INTRODUCTION MISSION STATEMENT Butler Manufacturing Company (Butler) is a team of talented, ethical and motivated individuals committed to providing our worldwide customers with products and services that create extraordinary levels of satisfaction. Butler’s Roof Systems Group prides itself in offering customers a wide variety of weathertight roof systems that are truly unsurpassed in design, function and value. MANUAL’S PURPOSE This Design/Specifier’s Manual serves as a reference manual for all builders, contractors, designers and customers seeking general information, specifications and details on the various Butler roof systems. The goal of the Design/Specfier’s Manual is to help user’s determine which of Butler’s roof systems and details are most appropriate for a project. PRODUCT INFORMATION The development and design of these roof systems began with the MR-24® and Butlerib II roof. The MR-24 roof system was the first modern-day standing seam roof system. Today, it is specified more than any other standing seam roof on the market. To meet the diversified needs of the ever-changing building market, Butler designed and developed the CMR-24®, VSR™, Butlerib® II. All of these roof systems are available with weathertightness warranties backed by Butler. Each of the roof systems offered by Butler is presented in this manual with a general description, CSI Specifications and panel-specific details. Questions, comments or additional assistance may be directed to Butler’s Roof Systems Group at (800) 478-0319.

ROOF SYSTEM

FEATURES

FASTENING/SEALANT

SYSTEM MR-24® Panel

* The MR-24 roof clip and tab assembly allows up to 2-1/2” of roof movement to accommodate thermal contraction and expansion. * Staggered panel endlaps provide greater strength and weathertightness. * The MR-24 roof system carries the highest wind uplift rating awarded by Underwriter’s Laboratories (UL) Class “90” rating. * Weathertight warranties are available up to 25 years. * Available in standard colors and Galvalume. *Factory Mutual (FM) approval.

* Weathertightness is assured because of Butler’s exclusive Pittsburgh Double-lock Standing Seam. Each roof panel is joined and mechanically turned 180° by the Roof Runner® portable roll-forming machine, completing a 360° seam along the entire length of the panel. * Roof clips hold roof panels to supporting structural members with no fastener holes to penetrate panels. * Every clip connection is prepunched to ensure proper alignment.

CMR-24® Panel

* The CMR-24 roof system uses the same exclusive panel seaming process and clip systems as the MR-24 roof system. * CMR-24 combines an interior steel liner and a vapor retarder to protect the insulation and to give the building interior a finished look with excellent energy savings. * Superior quality rigid board insulation is available in a variety of thicknesses (up to 4-1/4”) and insulating values. * The CMR-24 roof system features a UL-Class 90 wind uplift rating. * Weathertight warranties are available up to 25 years. * Available in standard colors and Galvalume. * FM approved.

* Because the CMR-24 roof system also uses the exclusive Pittsburgh double-lock standing seam, the same assurance of weathertightness is offered as the MR-24 roof system. Each roof panel is joined and mechanically turned 180° by the Roof Runner portable roof-forming machine, completing a 360° seam along the entire length of the panel. * A specially designed bearing plate under the roof panel clip evenly distributes the weight to prevent insulation damage.

VSR™ Panel

* The VSR roof system is specifically designed for architectural applications on roof slopes of 1/2:12 inches and greater. * Concealed fixed clips anchor the roof panels for panel lengths of 40 feet or less. Moveable clips are furnished for longer lengths and are capable of handling up to 2-1/2” of thermal movement. * The VSR panel configuration accommodates complex roof geometries and simplifies flashing designs, and can be used in continuous roof-to-fascia design treatments. * Both fluted and unfluted panel designs are available in 16” widths. * The VSR roof system features a UL-Class 90 wind uplift rating. * Weathertight warranties are available up to 25 years. * Available in standard colors and galvalume. * FM approved.

* Both the roof clips and panels have a factory-installed sealant to provide an extra measure of protection against leaks.

ROOF SYSTEM

FEATURES

FASTENING/SEALANT

SYSTEM

Butlerib® II Panel

*The Butlerib II roof system is the basic roof system for metal buildings, with panel lengths up to 40’ in three-foot widths used on roof slopes of 1/2:12 inches or greater. *Prepunched panels assure accurate installation and positive endlap matching. Slotted holes allow roof panels to move with thermal expansion and contraction. *1-1/2” corrugation makes the Butlerib II roof panel one of the strongest in the industry. *Purlin bearing full side-lap corrugation provides extra support at the panel side laps. *The Butlerib II roof system features UL-Class 90 wind uplift rating, and offers weathertightness warranties up to 10 years. *FM approved. *Available in standard colors and Galvalume

*Scrubolt™ fasteners are standard. Also available are Lock-Rivet™ fasteners and Self-Drilling Screws that hold roof panels to supporting structurals allowing thermal panel movement. An EPDM washer placed between the fastener head and the roof panel ensures weathertightness. *A special sealant groove is factory-formed into each roof panel for installing Panlastic (a butyl sealant that seals lap connections against capillary action of water). Sealant is field-applied.

Slope Build-Up Structural System

*The recommended slope range is 1/4:12 inches to 6-1/2:12 inches. *Maximum height of the Slope Build-Up System above the existing roof plane shall be 15’. *The Slope Build-Up System has been designed in accordance with the latest edition of the AISI, the AISC and in accordance with reliable engineering methods and practices. *The Slope Build-Up System, in most cases, requires a 3” minimum layer of blanket insulation to be used between the roof panel and the retrofit Z-purlin.

MR-24® STANDING SEAM ROOF SYSTEM BY BUTLER®

MR-24® Roof System

GENERAL INFORMATION The MR-24® roof system has demonstrated its outstanding performance since 1969 with over 2,000,000,000 (two billion) square feet in use on buildings subject to nearly every possible weather condition worldwide. Every part of the exclusive MR-24 roof system uses quality materials to insure a weathertight standing seam roof that performs like a monolithic steel membrane to protect the building. Every product feature, coupled with the use of acrylic coated Galvalume® for unpainted roofing, plus exclusive use of Butler-Cote® 500 FP finish system on galvanized steel, provides the durability and long life that owners and specifiers demand. THE MR-24® ROOF SYSTEM Roof panels are factory roll-formed 24” wide. The installed panels have two major corrugations, 2-3/4” inches tall with cross flutes 6” on center (o.c.) along the entire length of the panel. This reduces wind noise and improves walkability. Roof clips with stainless steel tabs (50% stronger than galvanized roof clip connectors) are secured to the prepunched supporting structural members. This insures proper alignment, maintains modularity and allows movement of roof panels without causing damage to the roof system. Detail Y001. MR-24® Panel Cross Section

MR-24® ROOF SYSTEM GENERAL

Panels are fastened directly to the eave structural members through factory prepunched holes in both panels and structural members. This transfers all roof movement to the ridge or high side expansion joint. Every connection is precisely prepunched at the factory, purlins, eaves, end splice, ridges and flashings to ensure proper alignment when the roof is installed. Proper alignment is critical to allow the completed, seamed together roof, to expand and contract with temperature change.

MR-24® Roof Clip The MR-24 prepunched panel endlap utilizes a two piece clamped connection. A structurally supported bottom reinforcing plate with four stainless steel studs are placed into the prepunched panels. Then a corrosion resistant aluminum top panel strap clamps the panel endlaps together eliminating any attachment to supporting structural members. This allows the entire roof to move as a single unit. The endlaps are also staggered to permit the full 360° “Pittsburgh” Double-lock seam through this critical joint.

Detail Y002. Mr-24 Clip and Tab Assembly The MR-24 roof system includes a complete line of accessories (IFCurbs, stainless steel gutter, etc.) designed to fit perfectly with the MR-24 system.



Date 2/5/08

Number 70-01.2


ROOF MOVEMENT The MR-24 roof system is designed to provide thermal movement at all intermediate roof structural members,

panel transitions and at the ridge. The roof panel clip is fastened directly to the intermediate roof secondary structural members. The tab in the roof clip is rolled into the roof panel seam. The clip allows thermal movement. A +/-100° F temperature differential, after roof installation, will allow total movement of 2-1/2”. Factory-installed, breakaway spacers insure that the tab is centered prior to panel seaming. These plastic spacers break away as the panel thermal movement occurs, allowing the roof panel clip to more freely.

MR-24 Roof Clip as Seamed to Roof Panels WEATHERTIGHTNESS Factory-applied sealant in the field rolled Pittsburgh Double-Lock seam joint eliminates capillary leaks. The roof panels are continuously and permanently field seamed with a four-stand, portable electric roll-forming machine called the Roof Runner. Roof panels are permanently seamed together with a 360° Pittsburgh Double-Lock Seam creating a single steel membrane, floating, monolithic roof. This seam is similar to seams on beverage cans and auto gasoline tanks. Roof panel runs that exceed panel shipping length are spliced together over roof secondary structural members to provide support. The panel endlap splice joins the panels together, but not to the secondary structural members. This allows the panels to move with thermal expansion and contraction. Roof Runner Seamer

MR-24 ROOF CLIP SYSTEM The MR-24 roof clip securely holds the panels to the supporting structural member system while allowing the entire roof to move from expansion and contraction caused by thermal forces. A. Made of high strength 304 stainless steel, the tab is wrapped around the bar to eliminate separation from the

clip. The stainless steel material folds tightly into the Pittsburgh Double-Lock seam for weathertightness. The MR-24 roof clip tab is more than 50% stronger than most other standing seam tabs made from carbon steel.

B. The yoke design includes heavy 16-gauge galvanized steel with stiffening ribs and flanges for added strength. The roof panels rest securely on the broad top of the yoke. The support flanges are turned down and every edge is smooth to allow roof movement. C. A special triangular-shaped steel bar lets the tab slide easily. A cadmium coating provides a smooth lubricated surface for tab movement. The bar is positioned high in the clip (only 1/8” below the panel) to eliminate binding as the roof moves. D. The self-centering sleeve keeps the tab perfectly positioned in the center of the clip. As the entire roof begins to move, the sleeves snap away to allow the tab and roof to move a full 2-1/2 inches. This permits buildings up to 500 feet wide without the need for special expansion joints. The self-centering sleeve breaks away at less than eight pounds of force but can easily withstand the jostling associated with shipping and installation.

PANEL ENDLAP SPLICES Panel endlap splices are made with stainless steel studs factory-welded to a back-up plate and then inserted through factory, prepunched panel holes. A butyl rubber tape sealant (with nylon spacers to assure sealant is retained within the splice and not over-compressed) is applied on the bottom panel before the top panel and aluminum panel strap is installed. Stainless steel flange nuts secure the panel strap to assure a weathertight connection. Panel splices are staggered between adjacent panel runs to allow for the full 360° Pittsburgh Double-Lock Seam through the splice joint. WIND UPLIFT The MR-24 roof system carries the highest ratings awarded for wind uplift. They are listed below. - Underwriters Laboratories (UL)-Class 90 Rating (UL Test 580). - ASTM E-1592 Wind Uplift Test Standard - Factory Mutual (FM 4471) FM I-60, FM I-75, FM I-90, FM I-120 and higher For many owners, a wind rating will result in lower insurance premiums for a building. Specific areas of roofs in high wind applications (over 100 mph) may require panel reinforcement and / or require use of 22-gauge in lieu of 24-gauge panels. ROOF MAINTENANCE Conventional roofs average $0.08 to $0.15 per square foot per year for maintenance (based on NRCA* data). The MR-24 roof averages $0.0075 to $0.015 per square foot per year for maintenance. ENERGY SAVINGS While most roof systems are designed to save energy, few actually do so without causing problems. For example, when thicker insulation is used with many types of roofs, fuel bills may be reduced, but the additional insulation may also speed up the inevitable deterioration of the roof membrane. The MR-24 roof system moves freely with the forces of expansion and contraction without causing any roof deterioration. The MR-24 roof is designed to incorporate blanket insulation (three to nine inches thick). *NRCA – National Roofing Contractors Association



Date 2/5/08

Number 70-01.5


When most metal roofs are installed, the insulation is often compressed at points where the roof is fastened to the structural member. Where insulation is compressed, a thermal short circuit is created, reducing energy efficiency. Optional 3/4” thermal blocks and taller roof clips can be used with this application at all roof secondary structural members to further increase energy efficiency. A roof requiring more than six inches of blanket insulation to meet energy requirements, may have the insulation applied between the roof secondary structural members (running perpendicular to the panel runs).

Detail Y006. Mr-24 Insulated Panel Without Thermal Spacer Block MOISTURE/VAPOR CONTROL The standard application of the MR-24 roof system using faced blanket insulation meets most building end use requirements where the interior relative humidity (RH) is 30% or less*. Building interiors requiring 30% to 50% RH, require blanket insulation with a quality, low-perm facing for specific vapor control, special attention to insulation application at joints and roof to wall transitions, and provisions for adequate air movement. Building interiors with RH requirements of 50% or greater, require a mechanical engineer’s approval of the insulation system planned in conjunction with adequate vapor control and air movement.

CMR-24® STANDING SEAM ROOF SYSTEM BY BUTLER®

CMR-24® Roof Panel System

GENERAL INFORMATION The CMR-24 roof system uses the same panel, seaming process and clip as the MR-24 roof system with the addition of a metal liner panel, vapor retarder and a rigid insulation board. CMR-24 panel seams are permanently rolled formed for weathertightness. A clip holds the panels securely to the structural system while allowing for roof movement. This roof system has demonstrated outstanding performance for over three decades. The CMR-24 roof system has been used on buildings subject to nearly every possible weather condition worldwide. CMR-24 has an added feature (a metal liner panel on the interior) that delivers a uniform, attractive interior appearance, diaphragm action-to-transfer wind loads, and added protection to the roof insulation from any interior abuse. ROOF MOVEMENT The roof system is designed to allow thermal expansion and contraction movement at all intermediate roof structural members, panel transitions, gable trim and at the roof ridge. The base of the panel clip rests on a bearing plate to prevent damage to the insulation board during installation of the roof panel clip. The clip is fastened through the insulation board and liner panel directly to the intermediate roof secondary structural members. The tab in the roof clip is secured into the roof panel seam. The clip allows 2-1/2” thermal expansion and contraction movement. A +/-100° F temperature differential, after roof installation, may produce a 1-1/4” movement. Factory-installed, breakaway tab spacers insure that the tab is centered prior to panel seaming. These tab spacers break away as panel thermal movement occurs.

CMR-24 Roof System Typical Seam

WEATHERTIGHTNESS Refer to the MR-24 Roof System section for complete description of the weathertightness features of the CMR-24 roof system. Refer to the 1.05 Warranties specification for available weathertightness and material warranty requirements for the CMR-24 roof system. DESIGN VERSATILITY Maximum spacing between intermediate secondary roof structural members is 5’-0 13/16” on the roof slope. The steel liner panel is 28-gauge, either Galvalume or galvanized (G-60) painted white on the exposed side and is secured to secondary structural members with self-drilling screws. The liner also acts to provide limited diaphragm bracing capability to transfer loads through the roof system (contact a Butler representative to obtain tested diaphragm capability). The CMR-24 roof system is designed to meet most live load and wind load codes for any roof configuration.



Date 2/5/08

Number 70-03.2


The structural engineer may elect to use a structural steel deck in lieu of the steel liner panel to provide for total designed roof diaphragm bracing capability. Refer to the New Construction Application section for application details. The minimum roof slope for the CMR-24 roof is 1/4:12 inches for warranty consideration. Refer to the 1.05 Warranties specification for available material and weathertightness warranties requirements. Adequate roof slope allows for proper roof drainage. Panel runs greater than 250’ with building widths of 500’ (from the low eave attachment to the end of the panel run) require a stepped roof transition expansion joint and structural joint transition. This requires an elevation change of 8” minimum for the roof step transition. WIND UPLIFT The CMR-24 roof system carries the highest ratings awarded for wind uplift. They are listed below. - UL-Class 90 Rating (UL Test 580) - ASTM E-1592 - FM (FMG test 4471) 1-60, FM 1-90, FM 1-120 and higher. For many owners, a wind uplift rating will result in lower insurance premiums for a building. Specific areas of roofs in high wind applications (over 100 mph) may require panel reinforcement and / or require use of 22-gauge in lieu of 24-gauge panels. ENERGY SAVINGS While most roof systems are designed to save energy, few actually do so without causing problems. For example, when thicker insulation is used with many types of conventional roofs, fuel bills may be reduced, but the additional insulation may speed up deterioration of the roof membrane. The CMR-24 roof is metal system and moves freely with the forces of expansion and contraction without causing any roof deterioration. The CMR-24 roof is designed to incorporate a minimum of 3/4” through 4-1/4” rigid insulation board over the top of the liner panels. The tested “U” value through the composite section with 3/4” Thermax® insulation board is 0.10 BTU hr./sq.ft./deg.F and is 0.054 BTU/hr./sq.ft./deg.F with 1-3/4” Thermax insulation board. MOISTURE/VAPOR CONTROL The standard application of the CMR-24 roof system uses a 0.0032” minimum thickness vinyl vapor retarder with a minimum perm rating of 1.0 meeting most building end uses where the interior RH is 30% or less.* Optional vapor retarders with higher perm ratings are available for building requirements with interior RH higher than 30%. These high humidity applications require special attention to vapor retarder joints along with provisions for adequate air movement. Building interiors with RH requirements of 50% or greater require a mechanical engineer’s approval of the insulation system designed in conjunction with adequate vapor control and air movement. *Consideration must be given to potential condensation areas such as interior gutters, skylight and roof to wall junctures.

VSR™ ARCHITECTURAL STANDING SEAM ROOF SYSTEM BY BUTLER®

VSR™ Roof System

GENERAL INFORMATION The VSR™ roof system is a versatile, structural standing seam roof designed primarily for architectural applications. The VSR roof system’s aesthetically pleasing appearance of clean, bold lines allow the freedom of design expression. The VSR roof can be utilized for almost any roof configuration, and easily accommodates complex roof geometries and simplifies flashing designs. Every product feature, coupled with the use of Galvalume for unpainted roofing, plus exclusive use of Butler-Cote 500 FP finish system (a full strength, low gloss 70% Kynar 500/Hylar 5000 painted finish) provides the durability and long life that owners and architects demand.



Date 2/5/08

Number 70-05.1

VSR™ ROOF SYSTEM GENERAL

Detail Y200. VSR™ Panel Cross Section

VSR™ ROOF SYSTEM The VSR roof panels are factory roll-formed 16” wide with two major corrugations 2” high on each edge. The flat of the panel is standard with longitudinal flutes 4” on center or optional without flutes. Seam sealant is installed in the female corrugation. Panels are standard 24-gauge in either acrylic coated Galvalume or galvanized (G-90 coating) with Butler-Cote 500 FP painted 70% Kynar 500/Hylar 5000 finish. The roof system is secured to the roof structural members by roof panel clips and self-drilling screws. The minimum slope for the VSR Roof System is 1/2:12.

ROOF MOVEMENT Moveable two-piece clips at the intermediate roof structural members, roof ridge and panel transitions allow thermal movement for all panel runs over 40’. Panel runs less that 40’ may use the fixed clip. The moveable roof clip tab is factory-centered and secured into the roof panel seam. The clip allows for 2-1/2” total movement of thermal expansion and contraction movement. A +/-100° F

Detail Y201. VSR™ Moveable Panel Clip



Date 2/5/08

Number 70-05.2


Temperature differential, after roof installation, will produce 2-1/2” of total movement. WEATHERTIGHTNESS Factory-applied sealant is field-seamed into the panel seam to eliminate leaks through the vertical ribs. The panels are continuously and permanently field-seamed to provide a single membrane, floating monolithic roof.

Detail Y202. VSR™ Fixed Panel Clip VSR roof panel runs that exceed the maximum panel length are spliced over, but not attached to the roof structural members. This design allows the panel to move with the thermal expansion and contraction forces. Panel splices include a splice plate and four flange nuts to provide a clamped joint with a watertight seal. Refer to the Warranties Section for available weathertightness and material warranties and their requirements. WIND UPLIFT The VSR roof system carries the highest ratings awarded for wind uplift. They are listed below. - UL-Class 90 Rating (UL Test 580) - Factory Mutual (FM4471) Approved 1-105, 1-60 and higher Windstorm Classifications VSR™ Panel Seam In many locales, a wind rating can result in lower insurance premiums for a building. Specific areas of roofs in high wind applications may require additional roof structural members to create less than a 5’-0” spacing. DESIGN VERSATILITY The VSR roof system is designed for installation on either a new roof construction or a retrofit roof construction when attaching to: - metal roof decks – per AISI specification - wood roof decks – per APA specification - bar joist secondary roof structural members p per SJI specification - wood joist secondary roof structural members – per TPI specification - metal building secondary roof structural members - slope build-up roof structural members



Date 2/5/08

Number 70-05.3


Maximum spacing between supporting secondary roof structural members is 5’-0-13/16” on the roof slope. The VSR roof system is designed to meet most live load and wind load requirements within the continental (48) United States and Alaska for eave heights of 30’ or less. Roofs on buildings with eaves greater than 30’ and high wind load conditions are reviewed per project for application of the VSR roof.

Detail Y205. VSR™ Fascia Note: Not recommended in snow areas The VSR roof system can easily accommodate the roof eave panel extending from the roof to the wall downward. This can be done at the low or high eave to provide an attractive integral fascia. (This treatment is not recommended in any areas where snow may accumulate on the roof.) VSR panels may show slight waviness, known as “oil canning”. This is a natural condition for panels of this type. Longitudinal flutes and low gloss Butler-Cote 500FP finish system in lighter colors will reduce these visible effects. Structural members may be required to provide an adequate roof slope for an existing roof. Refer to the Miscellaneous Retrofit Construction section for the installation of required Retrofit Roof Structurals. The maximum panel run is 250’ from the low eave structural member attachment to the end of the panel run. The recommended shippable panel length is up to 45’-0” by truck. ENERGY SAVINGS While most roof systems are designed to save energy, few actually do so without causing problems. For example, when thicker insulation is used with conventional roofs, fuel bills may be reduced, but the additional insulation may also speed up the inevitable deterioration of the roof surface. The VSR roof is designed for use with or without roof insulation (fixed roof clip). It can accommodate blanket insulation (three to six inches thick fiberglass blanket) over the top of the roof structural members with a moveable clip.



Date 2/5/08

Number 70-05.4


The VSR roof system moves freely with the forces of expansion and contraction without causing any roof deterioration. When most metal roofs are installed, the insulation is often compressed at points where the roof is fastened to the structural member. Where insulation is compressed, a thermal short circuit is created, reducing energy efficiency. Thermal spacer blocks (1/2” thick extruded polystyrene) used with tall moveable roof clips at all roof structural member, (except the eave) further increase efficiency.

A roof requiring high density or more than six inches of blanket (a two layer system with insulation running over the purlins and the remainder between the purlins) insulation to meet energy requirements, may have insulation applied between the roof structural members (running perpendicular to the panel runs). Roof design requirements for a rigid insulation board of 1/2” through 4-1/4” thickness may be incorporated over a vapor retarder on top of the

Detail Y206. VSR™ Tall Moveable Panel Clip building roof deck or liner panel. Use of a rigid insulation board requires the use of a bearing plate with the roof clip and longer fasteners. The VSR roof system is also designed to be applied directly over a plywood roof deck without insulation. 30-pound roof felt, other vapor retarder or thermal break material between the panel and the wood deck is recommended. MOISTURE/VAPOR CONTROL The standard application of the VSR roof system, using faced blanket insulation, meets most building end use requirements where the interior RH is30% or less*. Building interiors requiring 30% to 50% RH, require blanket insulation with a low perm rated facing for specific vapor control, special attention to insulation application at joints and roof to wall transitions, and provisions for adequate air movement. Building interiors with RH requirements of 50% or greater, require a mechanical engineer’s approval of the insulation system planned in conjunction with adequate vapor control and air movement. *Special consideration must be given to potential condensation areas such as interior gutter, skylights and roof to wall junctures.

BUTLERIB® II ROOF SYSTEM GENERAL

Butlerib® II Panel Sealant Location Predesigned and factory-fabricated accessories (curbs, gutter, etc.) are available to minimize field modification and help maintain a weathertight fit. BUTLERIB® II ROOF SYSTEM The roof panels are factory, roll-formed 36” wide with three major corrugation 1-1/2” high. The underside panel lap corrugation is roll-formed with a sealant groove to retain the sealant and a downturned return leg to provide support for roof traffic. This provides an improved weather sealing at the lapped corrugation. Prepunching at the factory helps assure proper fit and alignment of each panel joint to help keep the Butlerib II roof system weathertight. The slotted holes at the upslope end of the punched panels allows thermal movement of the panel without tearing the metal or loosening the fasteners. The exclusive Lockrivet fastener provides constant gripping strength and will not loosen with the thermal movement of the roof. An E.P.D.M. gasketed washer fits between the fastener head and the roof panel to insure weathertightness.

SLOPE BUILD-UP STRUCTURAL SYSTEM BY BUTLER®

GENERAL INFORMATION The Slope Build-Up Structural System is a versatile retrofit system that creates a new roof slope. The Slope Build-Up System is installed with Butler’s exclusive VSR and MR-24 standing seam roof systems. The system may be used over a flat, low-sloped or steep sloped roof supported by a metal, wood substrate or concrete deck.

Before The Slope Build-Up System with MR-24 is used to create slopes starting at 1/4:12 inches. VSR minimum slope is 1/2:12. MR-24 is installed on prepunched structural members to maintain proper panel alignment and insure weathertightness. Slope Build-Up also accommodates the versatile VSR architectural roof system designed for higher slope applications where the roof plays a predominant role in the building’s appearance. The recommended slope range of a roof system is 1/4:12 through 6-1/2:12 inches with a maximum height of the system above the existing roof plane of 15’-0”. During The Slope Build-Up system requires that a 3” minimum layer of vinyl faced blanket insulation be installed between the roof panels and the retrofit purlin to control condensation and dampen vibration and noise. If moisture can enter the attic space, then it is recommended that the newly created attic space be properly vented to allow any entrapped moisture to escape.

SLOPE BUILD-UP SYSTEM GENERAL

LAYOUT OF SLOPE BUILD-UP REROOF The layout of the Slope Build-Up Reroof System to the existing structure can be achieved in one of three ways. A. Base clips can be used if existing roof is not compressable. The base clip can be used on other applications such as beams or joists if the existing structure has an engineering review and can support the concentrated loads.

Slope Build-Up System With Perpendicular Base Z-Purlin Detail

B. Base Z-purlins parallel to top Z-purlins are used when existing secondary structural members run perpendicular to the NEW eave. (Parallel installation.)



Date 2/5/08

Number 70-11.5


C. Base Z-purlins perpendicular to the top Z-purlins are used when existing secondary structural members run parallel to the NEW eave. (Perpendicular installation.)

Slope Build-Up System With Parallel Base Z-Purlin Detail BASE SPANNING Z-PURLINS Base spanning Z-purlins are available in two standard web depths 3” and 5-1/2” and are supplied 15’-0” long. The purlins are typically installed perpendicular to the existing roof structural members. The design of the attachment of the new purlins to the existing structural members is the responsibility of the installation contractor. The purlin-to-purlin connections are made with a mechanically fastened lap splice creating a continuous purlin design. Base purlins can often be installed directly over an existing roof system with little preparatory work. This works well with aging single-ply membrane roof systems. However, the aggregate on asphalt or coaltar pitch built-up roofs is generally removed with a power broom before installing the new structural system. The ballast on single ply systems must always be removed.

SLOPE BUILD-UP SYSTEM CSI SPECIFICATIONS

1.03 DESIGN INFORMATION 1. The recommended slope range of the Slope Build-Up System is 1/4:12 inches through 6-1/2:12 inches. 2. Maximum height of the Slope Build-Up System above the existing roof plane shall be 15’-0”. 3. The Slope Build-Up System has been designed in accordance with the latest edition of the AISI, the AISC and in accordance with reliable engineering methods and practices. 4. The required design loads (dead, live, snow and wind) shall be applied to the Slope Build-Up System. The system will transfer these loads to the existing structure. This load transfer will result in concentrated loads being applied to the existing structure. Butler will not be held responsible for the structural integrity of the existing structure due to the additional dead load of the new roof system on the existing structure. A registered professional engineer should review the existing structure to determine the structural capacity; 5. The Slope Build-Up System, in most cases, requires a 3” minimum layer of faced blanket insulation to be used between the roof panel and the retrofit Z-purling to control condensation and dampen roof vibration and noise. If moisture can enter the attic space, then it is recommended that the newly created attic space be properly vented to allow any moisture to escape. 1.04 ROOF PANELS The Slope Build-Up System is designed to interface with either the Butler MR-24 Standing Seam Roof System or the VSR Architectural Standing Seam Roof System.

LOW PROFILE METAL OVER METAL™ RETROFIT APPLICATION BY BUTLER®

Low Profile Metal Over Metal™ System

GENERAL INFORMATION The Low Profile Metal Over Metal™ (MOM) System allows for the efficient installation of the MR-24 standing seam roof system over an existing through-fastened rib type roof with a minimum roof slope a1/4:12 inches and major corrugation height of 1-1/2” or less, spaced at 1”-0” on center. The MR-24 roof panels used on this system are permanently seamed together with a full 360˚ Pittsburgh Double Lock seam to assure weathertightness and long-term performance with minimal maintenance expense. The MR-24 roof clips, installed in predrilled holes, securely attach the roof panels to the existing supporting structural members with stainless steel tabs roll-formed into the panel seam. Stainless steel tabs are more than 50% stronger than coated carbon steel standing seam tabs. The clip design will accommodate expansion and contraction forces in roofs up to 500 feet wide. Panel support blocks rest on the flat of the existing panel and provide a bearing surface to transfer loads through the flat of the MR-24 roof panel to the existing structural members.

INTRODUCTION TO RETROFIT CONSTRUCTION BY BUTLER®

GENERAL INFORMATION This section provides product specifications and application details for the various retrofit Butler roof systems. Many retrofit options are available for roof repair or replacement. They are discussed below. STRUCTURAL ANALYSIS OF EXISTING BUILDING Structural analysis of the existing roof deck and structural members must be performed to determine if any reinforcement of the existing building’s framing is required. Analysis should be done by the building owner’s engineer to assure the application of the Retrofit system continues to meet current local building code requirements. SLOPE BUILD-UP STRUCTURAL SYSTEMS Butler provides specific design assistance and application detailing to produce any desired Slope Build-Up System and roof system. All roof applications can be applied to Slope Build-Up. Retrofit structural height change maximum is 15’, and must be designed to meet local building code requirements. LOW PROFILE METAL OVER METAL™ ROOF SYSTEMS The Low Profile MOM minimum application for roof slopes is 1/4:12 inches or greater. This system is designed to allow for the installation of the MR-24 roof system over an existing ribbed roof without the use of additional roof structural members in the roof field. The Retrofit Roof Panel Clip is installed through the existing roof panel into the existing building purlin on 2’-0” spacing. The MR-24 roof panel is then installed and seamed into place. The existing roof major corrugations must be 1’-0” on center and not be greater than 1-1/2” in height. HIGH PROFILE METAL OVER METAL™ ROOF SYSTEMS The High Profile MOM minimum application is to roof slopes of a1/4:12 inches or greater. This system is designed to allow for the installation of the MR-24 and VSR roof system (minimum 1/2:12) over an existing metal roof with major corrugations higher that 1-1/2” but less than 3” in depth. High Profile MOM uses spacer clips and 1-1/4” spanning members (Hat Sections) in the existing roof field to raise the new roof line above the existing roof panel corrugation. LIGHT GAGE STEEL TRUSSES Factory made light gage steel trusses can provide slope and simplify the installation of hip and valley framing. Light gage steel trusses can span up to 80 ft. and must have at least a 2:12 slope if the “heal height” is 0 inches.

RETROFIT CONSTRUCTION GENERAL

FASTENING A RETROFIT ROOF TO AN EXISTING ROOF

The installation of a standing seam roof in a reroof application may involve any number of existing conditions to which the new components must attach. In job planning and estimating, a considerable amount of effort must be put into the design of the installation. Some examples of existing conditions or components that can affect the type and size of fasteners are as follows:

1. Material to which the new roof components are to be fastened. 2. The thickness of roofing or existing insulation to remain above the existing structural components. 3. The condition of existing roofing, roof deck or structural component. Don’t forget that a leaky roof has

allowed water to stand on or adjacent to structural materials that could have deteriorated under these conditions.

4. Uplift requirements of the building code. 5. Preference of the installer of the new roof system.

It is critical that an on-site inspection of the roof be made. To determine the correct fastener to use in attaching the new roof structural to the old roof structural system, know the thickness of materials penetrated, types of materials, the condition of the old roof and the installation preference. The information gathered from the on-site inspection helps determine the specific fastener or series of fasteners for the specific application. Using information from a fastener supplier, determine the best fastener type and size for the project. The fastener or fasteners must be tested on each specific building to be reroofed. The pullout values must be determined during the on-site testing to determine the actual Fastener Holding Capacity versus the Published Theoretical Values. Actual fastener pullout values can be determined with the use of suitable Fastener Pullout Tool that shows the pounds force required. The method of obtaining test results is very simple and is as follows:

1. Determine the areas of the roof to be tested. The areas to be under the new roof structurals should be tested. A good rule of thumb is to run at least one pullout test for every 2,000 square feet on roofs up to 20,000 square feet and one pullout test for every 4,000 square feet on roofs 20,000 square feet and over. Large roofs have the possibility of having a wide range of conditions on the same roof, giving very different tested pullout values.

2. Drive the screw into the existing roof deck or structural member in an approved manner. 3. Attach the Fastener Pullout Tool to the fastener head. 4. Use the Fastener Pullout Tool and read the pullout force value (in pounds) required to pullout the fastener. 5. Repeat the test in all the other areas identified to be tested. (See step 1.)

Note: Remember to take along some mastic, caulking, roof cement, felts, rubber and etc. to fill the holes made in the roof when fasteners were pulled out.

RETROFIT CONSTRUCTION FASTENER CALCULATIONS

The “Fastener Pullout Tool” is available through Dynamic Fasteners of Kansas City, Missouri or other fastener suppliers. Determine the actual tested pullout value to use to select the quality of fasteners per roof attachment connection in the following manner:

1. Take all the values for the roof or roof area (for a large roof) tested and discard the highest and lowest values (these are typically out of line with average values).

2. Take the average of the remaining values. 3. Repeat, if necessary, for values from other roof areas.

Example Test Pullout Values= 200 pounds 350 pounds 455 pounds (DISCARD) 225 pounds 300 pounds 405 pounds 305 pounds 180 pounds (DISCARD) Add together the remaining pullout values and divide by the number of pullout values added. Add: 200 pounds 350 pounds 225 pounds 300 pounds 405 pounds 305 pounds 1785 divided by 6 = 297.5 pounds The test pullout value is 297.5 pounds.

The pullout value is the force, in pounds, a fastener will resist if a pulling force (wind uplift) is exerted on it. The pulling force is generated by wind uplift forces, acting on the roof, and is transmitted through the roof to the structural member attachments. The wind uplift forces are determined by he local building code wind load requirements and applied per the building code. If UL-Class 90 Wind Uplift rating is required, it is recommended that a 120 psf uplift value be compared to the building code uplift for a fastening system which equals or exceeds, the UL-Class 90 Wind Uplift test on the roof panel. The higher of the uplift values should be used in determining the minimum required uplift resistance. The minimum required wind uplift resistance is a calculated value. It can be determined by multiplying together the wind load required by code, the spacing of the structurals and a factor of safety. Butler Manufacturing Company recommends a factor of safety of at least three, be applied to the required uplift resistance. This factor of safety takes into account the wide variability in holding strength of the old roof, because the tested pullout values might not represent all the minimum values.



Date 2/5/08

Number 70-14.3


In general, a minimum required uplift resistance value of 120 psf should meet, or exceed, most building code design uplift requirements when the wind speed in 90 miles per hour or less. However, the design wind uplift is a function of several variables (i.e. wind speed, exposure, type of occupancy, mean roof height, slope, etc.) and it varies throughout the roof depending on location (i.e. roof zone) as determined by the specific building code. Therefore, it is always Butler’s recommendation, that the building code design wind uplift be calculated and increased by a minimum safety factor of 3.0 before arbitrarily using the 120 psf minimum required uplift resistance value. An example of the required wind uplift resistance (wind load 80 mph or less) of a typical roof attachment fastener is as follows: Local Building Code Wind Load: Required wind uplift load = 20 psf (determined by the Building Code for a specific roof zone) Factor of Safety = 3.0 Secondary structural spacing = 5.0 feet Required uplift resistance = 20 psf x 3.0 x 5.0 feet = 300 lbs. per foot of secondary roof structural member UL-Class 90 Wind Uplift Load: Wind uplift test load = 120 psf (No factor of safety used) Secondary structural spacing = 5.0 feet Required uplift resistance = 120 psf x 5.0 = 600 lbs per foot of secondary roof structural member The quantity of fasteners required for secondary structural attachment would be the required uplift resistance divided by the actual tested pullout value of one fastener. The tested fastener pullout value must always be greater than the required uplift resistance in order to provide a reasonable factor safety for the actual fastener installation. The following example shows how the fastener quantity can be determined using various tested pullout values with the previous calculated required wind uplift resistance. Example: Using the required local building code uplift resistance = 300 lbs/ft Roof Project Test Pullout Value Required Fasteners 1 320 lbs/fastener 300/320 = 0.94 per ft. or 1 per foot 2 450 lbs/fastener 300/450 = 0.67 per ft. or 1 every 18 inches 3 600 lbs/fastener 300/600 = 0.5 per ft. or every 24 inches 4 150 lbs/fastener 300/150 = 2.0 per ft.



Date 2/5/08

Number 70-14.4


Currently Underwriters Laboratory does not require the structural to roof connection to be tested and included in their listing of tested and rated construction numbers. Determining the required number of fasteners by the previously described procedure (i.e. using the greater of the building code design uplift load and the UL-Class 90 wind uplift test load) will provide an attachment design with an adequate factor of safety for the specified loading. The contractor is responsible for selecting the type and length of fastener required. The contractor must also determine the quantity of fasteners. This can be done by giving fasteners per lineal foot of structural member, fasteners per base clip or total quantity of fasteners. The following information has been developed to aid in the selection of the proper fastener: Theoretical Ultimate Fastener Pullout Strength (1) Steel Deck or Structural Wood Wood Concrete

IMPORTANT NOTES

1. The pullout values given are for fasteners in new materials tested under ideal (laboratory) conditions by the fastener suppliers. The values are given only as a guide to determine the type of fastener that might be used for a certain application.

2. When using these values for new construction, appropriate safety factors must be applied to the pullout values. Butler recommends a minimum safety factor of 3.0.



Date 2/5/08

Number 70-14.5


3. When using these values for older, existing construction, Butler recommends that actual fastener pullout tests be run on the actual materials with which the fasteners will be used. The Fastener Pullout Tester has been developed to permit performance testing of fasteners under actual on-site conditions. For more information on Fastener Pullout Tester, please consult the fastener equipment supplier, such as Dynamic Fasteners of Kansas City, Missouri or others.

4. The load requirements used to choose specific fasteners for a project are as follows: a. UL-Class 90 uplift requirements should be used if they are higher than the local code

requirements, if UL-Class 90 certification is required. A 120 psf (lbs per sq. ft.) uplift with no safety factor, will meet or exceed, the UL-Class 90 uplift test on the roof panel.

b. Local building code wind uplift requirements should always be used to choose the minimum number of fasteners:

Example: Local Code Uplift Reg. x Safety Factor x Structural Spacing 20 psf 3.0 5.0 ft. = 300 lbs/ft. of structural UL-Class 90 Uplift Load Structural Spacing 120 psf 3.0 = 600 lbs./ft of structural Summary: Use 600 lbs./ft. – the larger of the two uplift requirements.

The paragraphs below include specific requirements for each Butler roof system and its application to New Construction. MR-24® AND CMR-24® ROOF SYSTEMS MR-24 AND CMR-24 roof systems require prepunched structural members for proper alignment of all roof panel seams and for allowing the planned thermal movement of the roof. Application to roof secondary structural members that are not punched require the addition of field-punching or field-drilling of holes to some of the intermediate steel structural members. Thermal spacer blocks are placed on structural members that are one inch (1”) lower than the eave structural member. NEW CONSTRUCTION APPLICATION REQUIREMENTS A. Eave Roof Structural Member must be a prepunched structural with the top elevation in the same plane as the flat of the MR-24 panel. (Refer to MR-24 Roof System Detail Y033.) A spanning member (hat channel) may be used for the eave secondary structural. When a stepped roof transition is required (due to building width) the first roof secondary structural member (at the eave of the raised portion of the roof) must be punched and at least eight inches higher than the lower roof panel. (Refer to MR-24 Stepped Elevation Detail Y031 or Y032.)

A. Eave Roof Structural Member must be a prepunched structural with the top elevation in the same plane as the flat of the MR-24 panel. (Refer to MR-24 Roof System Detail Y033.) A spanning member (hat channel) may be used for the eave secondary structural. When a stepped roof transition is required (due to building width) the first roof secondary structural member (at the eave of the raised portion of the roof) must be punched and at least eight inches higher than the lower roof panel. (Refer to MR-24 Stepped Elevation Detail Y031 or Y032.) B. Intermediate Roof Structural Member(s): 1. Are always punched at the top row of a panel run. 2. Require prepunched holes at the fifth roof secondary structural member (approximately 20 feet) from the eave and at every fifth roof secondary structural thereafter, prior to the end of the panel run. (An electric-powered hydraulic Bar Joist Top Chord Puncher may be leased from Butler’s Roof Runner Department for this purpose.) 3. All other roof secondary structurals may have their clips attached with the appropriate self-drilling screw. Care must be taken to assure that these roof clips are properly aligned with the other roof clips attached in the prepunched holes. If all roof clips are not in alignment, adequate roof movement may not occur and thermal forces may cause roof deterioration due to stress buildup. C. Bar Joist Lateral Bracing requirements are: 1. MR-24 Roof System provides no lateral bracing capability for bar joists, therefore lateral bracing must be provided. (Not by Butler.) 2. CMR-24 Roof System provides limited lateral bracing capability for bar joists. If this is planned, then provisions for providing bracing must be engineered into application requirements for each specific roof project.

NEW CONSTRUCTION APPLICATION

GENERAL

The above text outlines some of the requirements for these roof systems to qualify for the roof warranties listed in the warranties Section. The roof must meet or exceed the minimum roof slope and other requirements. VSR ROOF® SYSTEM The VSR Roof System panel clips are attached to all roof structurals with appropriate self-drilling screws. If all roof clips are not in alignment, adequate roof movement may not occur and thermal forces may cause roof deteriorations due to stress buildup. Top elevation of the eave roof structural must be in the same roof plane as the flat of the VSR roof panel. (Refer to VSR Roof System Detail Y225.) When using a moveable panel clip, the panel will be attached directly to the eave structural member. All intermediate structural members must be lower than the eave structural member by either a1/2” for short moveable clips or 1-1/4” for tall moveable clips. The VSR roof system provides no lateral bracing capability when applied directly to the top chords of either bar joists or wood joists. Therefore, required lateral bracing must be provided. VSR roof system applied over roof decking, requires the decking, not the VSR roof system, to provide lateral bracing to top chords of either bar joist or wood joists. The above text outlines some of the requirements for the VSR roof system to qualify for the roof warranties listed in the Warranties Section. The roof must meet or exceed the minimum roof slope and other requirements. BUTLERIB® II ROOF SYSTEM The Butlerib II roof system is designed for application to light gauge, steel eave structural members and purlins that have lateral bracing. The Butlerib II roof system is NOT designed for application to top chords of either bar joists or wood joists because of the stiffness of these structural members and the potential for slotting at panel fasteners. The above text outlines some of the requirements for the Butlerib II roof system to qualify for the roof warranties listed in the Warranties Section. The roof must meet or exceed the minimum roof slope and other requirements.

GENERAL

LITE*PANL panels are translucent Cool White, fiberglass reinforced plastic panels (insulated or uninsulated). The panels provide diffused natural light through the roof system while maintaining weathertightness. The LITE*PANL panels are used with MR-24, CMR-24 and Butlerib II roof systems.

Pipe flashing units are constructed of Ethylene Propylene Diene Monomer (EPDM) black synthetic rubber. A ductile, aluminum reinforcing ring is bonded to a rubber flange on the base of the flashing unit. Temperature range is -25°F to 250°F. Pipe flashings are available for a1/4” to 13” outside diameter pipe. Pipe flashing units are used with all Butler roof systems.

The ridge ventilator is non-powered, gravity operated and designed to fit Butlerib II, MR-24 and CMR-24 roof systems for roof slopes from 1/4:12 to 4:12 inches. The ventilators are constructed of 24-gauge, galvanized steel, factory-painted a white color. They are nominal 10’ long with a 9’ throat opening. The ventilators can be installed as a single unit or in multiple units along the ridge of the building. A chain-driven, worm screw operator mechanism operates the damper. The ridge ventilators are used with MR-24 and CMR-24 and Butlerib II roof systems.

The roof ventilator is fabricated from white color Acrylonitrile-Butadiene-Styrene (ABS) plastic and has the same configuration as the Butlerib II roof panel for ease of installation.

GENERAL

The IFCurb is an internally fastened roof curb constructed of maintenance-free, aluminum. The IFCurb is approved for “Weathertight Gold Warranty” when ordered through the Butler Roof Division. This product is available in six standard sizes or can be custom fabricated and tapered to match the roof pitch. It is shipped with all mounting accessories and instructions. The IFCurb is available for MR-24, CMR-24 and VSR roof systems.

The OTS Curb is a low cost solution for smaller roof penetrations. It is constructed form long-lasting, maintenance-free aluminum. Its unique “diagonal” positioning allows water to flow freely around the curb. The OTS Curb is available in six standard square sizes. Custom sizes are also available to 30” square. The OTS Curb is available for MR-24 and CMR-24 roof systems.

The Service Way is designed to protect the roof from frequent roof traffic and heavy concentrated loads which can damage roof panels, reduce roof life and possibly void the roof warranty. The Service Way is fabricated from 20-gauge, aluminum-zinc coated steel and supports concentrated loads up to 500 pounds. The Service Way provides a skid resistant surface and is installed so as not to penetrate the roof panels. The Service Way is available for MR-24 and CMR-24 roof systems.

This alternate design for heavy equipment uses a steel frame elevated above the roof and supported on pipe columns with pipe flashings penetrating the roof. Plastic curbs or light gauge metal curbs are used where duct-work passes through the roof. The combination of roof curb and elevated angle frame is available with MR-24, CMR-24, Butlerib II and VSR roof systems. The elevated angle frame is not supplied by Butler.

SERVICE-WAY FOR MR-24® AND CMR-24® ROOF SYSTEMS

• Economical compared to other known products. • Fast and easy installation. • Only five different parts used plus fasteners. • Install in either direction. • All panels are Galvalume steel (AlZn). • No fasteners penetrate the roof. • Can be relocated. • No special tools needed. • Skid resistant surface. The Service-Way is designed for use on MR-24 and CMR-24 roofs for both new and existing buildings. It is not recommended for roofs with slopes exceeding 1”:12”. It is common practice to mount HVAC units, skylights, hatches, fans, headhouses, etc. on the roofs of buildings. Roof-mounted units or components generally require servicing or access on a periodic basis thus increasing roof traffic. Frequent foot traffic and heavy concentrated loads can easily damage roof panels, greatly reduce expected roof life, and possibly void the roof warranty. The MR-24 Service-Way will solve this roof traffic problem. AVAILABILITY A. Both the parallel Service-Way (parallel with the panel ribs) and the perpendicular Service-Way (perpendicular

with the panel ribs) are packaged 16 lineal feet per carton. All necessary parts for installation, including erection drawing 1080613, are included in the carton.

The hidden fasteners provide an enhancement to the building’s appearance and improve its security. Laminated to the inside face of the StylWall II Flat panel is a rigid insulation board that improves the insulating properties of the wall and the flatness of the metal face. The tested “U” value of the panel with the board laminated to the interior surface equals one inch of fiberglass blanket insulation. Reducing the amount of additional insulation and the overall cost of the wall. The rigid backer, along with the special joint design, allows simple and secure installation. Because each new panel is positioned perfectly by nesting against the previous panel, a uniform joint is created each time with no unsightly variation in the size of the joint. The 16-inch panel width, combined with the side “return leg” acts like a metal stud allowing almost any conventional finishing material to be easily fastened to the interior of the wall system.

Butler Assurance The Butler Watertight Gold limited roof system warranty is backed by Butler Manufacturing Company, the worldwide leader in metal roof systems. With Butler you can be sure you have invested wisely in a quality roof solution that will yield years of worry free performance. Several key components make the Butler Watertight Gold warranty unique in the metal roofing industry. These items are an important part of the overall program to assure roof performance. When comparing warranties, be sure that each item is included.

• Warranty provides for material and labor to repair leaks. • Warranty to cover manufacturer supplied roof panels, trims, flashings, roof curbs, and manufacturer-

approved contractor-fabricated flashings. • Warranty to be non-prorated, 10 years or 20 years in length, with the option to extend the 10-year

warranty an additional 10 years. • Combined manufacturer/installer liability to be the original price paid for the installed Butler roof system. • Contractor’s installation supervisors to be manufacturer trained, tested, and certified through a formal

training program. • Manufacturer to provide third-party inspections upon project completion. Inspectors to be roof

manufacturer-trained employees of an independent roof consulting and/or testing firm. • Warranty to be transferable to a new owner if building ownership changes.

* Review the warranty document for a more complete explanation of coverage conditions and limitations. TYPICAL QUESTIONS When comparing warranties, take a minute to ask the following questions: • Does the warranty exclude damage from gale force winds? Strong gale force winds range from 47-54 MPH as listed in the Beaufort Scale. Damage caused by winds at or above this speed is cause for claim rejection with some warranties. Butler roof system design and warranty coverage is consistent with building code requirements for roof design to handle wind speeds that range from a minimum of 90 MPH to 140 MPH or more.

• Does the warranty require the installer to have a manufacturer trained, tested, and certified

installation supervisor on site full time during installation? Most other manufacturers’ warranties will not have a requirement regarding the experience, training or certification of the installation personnel or installation supervisor. A Butler trained installation supervisor, on-site full time during roof installation, can provide Butler-issued photo certification I.D. upon request. • Does the warranty program provide for timely and well defined claim resolution? Under other warranties, the owner is left to “find” the responsible party and enforce the terms of the warranty. • Does the warranty provide coverage up to the original installed price for the roof system? Most other roof warranties have fixed dollar liability limits that range from $0.20 to $2.00 per square foot. These warranties also exclude many roof system components such as trims and roof penetrations. Some warranties are even pro-rated, reducing coverage each year of the roof’s life. The Butler Watertight Gold warranty provides coverage up to the roof system’s original installed price for the full warranty period.

COLORS AND FINISHES GENERAL

ROOF DRAINAGE GUIDELINES

GENERAL INFORMATION This section provides guidance and assistance when determining roof drainage requirements for Butler and other commercial buildings. In many conventional designs, roof drainage must be considered. In conventional construction, and as this applies to retrofitting of conventional building roofs, several factors influence the drainage design and/or the slopes and direction of slopes on new roofs. The following are guidelines used to determine downspout sizing and spacing based on rainfall intensities I specific locations utilizing Butler standard gutter sizes and shapes. The theory and application of fluid mechanics as presented herein conforms to those accepted and utilized in fluid mechanics and engineering practice. Butler can assume no legal responsibility for design of gutter and downspout systems by unauthorized persons applying the principles and procedures outlined in this guide, in any manner, outside the scope and intent of the instructions contained herein. In no way do the roof drainage requirements, set forth in this guide, supersede the legal requirements set forth in various building codes of cities, towns, municipalities or states. Strict compliance with local ordinances is mandatory. RAINFALL INTENSITY Rainfall intensity (U.S.) is expressed in inches per hour. This quantity is determined from data obtained by measuring the accumulation at five (5) minute intervals throughout the entire rainstorm. The largest accumulation for a specific duration is then prorated over an hour. This quantity is not necessarily the total quantity of rain that will fall during a storm, but rather the maximum rate at which it falls during a small part of the storm. It should be recognized that the shorter the duration of a rainfall, the greater the expected average intensity during that period. In other words, during a storm lasting 25 minutes, any period less than 25 minutes in length, can have an average rainfall intensity greater than that of the entire storm. The critical period of rainfall for any building is that which produces maximum runoff. This period is equal to the time of heaviest concentration, since shorter periods do not represent total rainfall, and longer durations show a lesser rainfall intensity. The time of concentration is the time required for the maximum runoff rate to develop and is equal to the time required for a drop of water to run from the most remote point of the building to the point for which runoff is being estimated. Another factor that enters into intensity values is the return period. Presumably, an intensity value obtained from a weather station that has maintained maximum records for 50 years will be equaled or exceeded once every 50 years. This is called a 50-year return period. An intensity value which is exceeded twice in 50 years, or once in 25 years, is called a 25-year return period. The same manner determines 10, 5 and 2-year periods.

Number 70-20.1

ROOF DRAINAGE GENERAL

DESIGN CRITERIA Design requirements for interior gutters are intensified because an inadequate drainage system may cause structural or content damage. With exterior gutters, however, overflowing in most cases is not of serious consequence. Remember that the shape and size of the collector box is a key consideration with multi-width and interior gutters. See Butler Drawing C-107134 for a suggested method of field fabricating a typical collector box and screen. Intensity values for a period of five minutes and a return period of 50 years should be used to determine downspout requirements for interior systems. Intensity values to determine downspout requirements of exterior systems should be based on a five-minute duration and a five-year return period. Use the following technical data to design the roof drainage system for your building.
