13 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 (70% Kynar) Kynar 500/Hylar 5000 painted 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 08/02/

14 Panels are fastened directly to the eave structural members through factory pre-punched holes in both panels and structural members. This transfers all roof movement to the ridge or high side expansion joint. Every connection is precisely pre-punched 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 pre-punched panel endlap utilizes a two piece clamped connection. A structurally supported bottom reinforcing plate with four stainless steel studs is placed into the pre-punched 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. MR-24 ROOF SYSTEM GENERAL 08/02/

15 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 produce 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 move 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 the same as seams on beverage cans and auto gasoline tanks. Roof panel runs that exceed panel shipping lengths 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.

16 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 with expansion and contraction caused by thermal forces. A. Made of high strength 304 series 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 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 sleeves keep 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. MR-24 Roof Clip MR-24 ROOF SYSTEM GENERAL 08/02/

17 PANEL ENDLAP SPLICES Panel endlap splices are made with stainless steel studs factory-welded to a back-up plate and then inserted through factory, pre-punched 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 are 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 $ 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). Detail Y005. MR -24 Roof Maintenance Cost Comparison Chart *NRCA National Roofing Contractors Association MR-24 ROOF SYSTEM GENERAL 08/02/

18 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. Detail Y007. MR-24 Insulated Panel With Thermal Spacer Block *Consideration must be given to potential condensation areas such as interior gutters and skylights, which are susceptible to condensation problems.

44 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 the entire 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 provide roof movement to accommodate thermal expansion and contraction 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 GENERAL 08/02/

45 MR-24 roof panel Bearing plate Thermax insulation board Liner panel 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 /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 wind loads to the walls (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. Detail 101. CMR-24 Panel Clip and Tab Assembly CMR-24 ROOF SYSTEM GENERAL 08/02/

46 The structural engineer may elect to use a structural steel deck in lieu of the steel liner panel to provide for total 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 FM (FMG test 4471) 1-60, FM 1-90, FM 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 a 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 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 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.

69 VSR II ARCHITECTURAL STANDING SEAM ROOF SYSTEM BY BUTLER VSR II Roof System GENERAL INFORMATION The VSR II roof system is a versatile, structural standing seam roof designed primarily for architectural applications. The VSR II roof system s aesthetically pleasing appearance of clean, bold lines allows the freedom of design expression. The VSR II 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. VSR II ROOF SYSTEM GENERAL 08/02/

70 Detail Y200. VSR Panel Cross Section VSR II ROOF SYSTEM The VSR II roof panels are factory roll formed 16 wide with two major corrugations 2 high on each edge. The flat of the panel has subtle striations. Seam sealant is factory installed in the female corrugation. Panels are standard 24-gauge steel with either acrylic coated Galvalume or Galvalume with Butler-Cote 500 FP painted (70% Kynar) 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 II Roof System is 1/4:12. Detail Y201. VSR II Moveable Panel Clip ROOF MOVEMENT Moveable two piece clips at the intermediate roof structural members, roof ridge and panel transitions allow for thermal movement of the roof panels relative to the substructure. The moveable roof clip tab is factorycentered and secured into the roof panel seam. The clip allows for 2 total movement of thermal expansion and contraction movement. A +/-100 F temperature differential in a 200 foot run of steel panel, after roof installation, will produce 2 of total roof clip 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. VSR II 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. VSR II ROOF SYSTEM GENERAL 08/02/

71 WIND UPLIFT The VSR II roof system carries the highest ratings awarded for wind uplift. They are listed below. - UL-Class 90 Rating (UL Test 580) - Factory Mutual (FM4471) Windstorm Classifications 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. VSR II Panel Seam DESIGN VERSATILITY The VSR II roof system is designed for installation on either new roof construction or retrofit roof construction when attaching to: - metal roof decks per AISI specification - wood roof decks per APA specification - bar joist secondary roof structural members - per SJI specification - wood joist secondary roof structural members per TPI specification - metal building secondary roof structural members - slope build-up roof structural members The maximum spacing between supporting secondary roof structural members is /16 on the roof slope. The VSR II 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 II roof system. Detail Y205. VSR Fascia Note: Not recommended in snow and/or ice areas VSR II ROOF SYSTEM GENERAL 08/02/

72 The VSR II 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 application is not recommended in any areas where snow and/or ice may accumulate on the roof.) VSR II panels may show slight waviness, known as oil canning. This is a natural condition for panels of this type. The standard subtle striations 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 200 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 II roof is designed for use with or without roof insulation. It can accommodate blanket insulation (three to six inches thick fiberglass blanket) over the top of the roof structural members. 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). The VSR II 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 (1/4 thick polystyrene) used with either short or tall moveable roof clips at all roof structural members (except the eave), further increase energy efficiency. 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 building roof deck or other metal panel. The use of a rigid insulation board requires a bearing plate under the roof clip and the use of longer fasteners to secure the panel clip. The VSR II roof system can be installed directly over a plywood or steel roof deck without insulation. Minimum 30-pound roof felt or other vapor retarder is recommended. A sound minimizing material and/or slip-sheet may be installed between the panel and the roof deck. MOISTURE/VAPOR CONTROL The standard application of the VSR II roof system, using faced blanket insulation, meets most building end use requirements where the interior RH is 30% 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 Panel Cross Section BUTLERIB II ROOF SYSTEM GENERAL 08/02/

97 Butlerib II Panel Sealant Location Pre-designed 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 corrugations 1-1/2 high. The underside panel lap corrugation is roll-formed with a sealant groove to retain the sealant and a down-turned return leg to provide support for roof traffic. This provides an improved weather sealing at the lapped corrugation. Pre-punching 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 allow 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 EPDM gasketed washer fits between the fastener head and the roof panel to insure weathertightness. Detail Y301. Butlerib II Detail Y302. Butlerib II Detail Y303.

98 WEATHERTIGHTNESS The sealant groove (formed into the underside panel lap corrugation and upper panel end) provides the installer with a clear and specific location for the sealant. The butyl rubber sealant remains pliable for decades and keeps the roof weathertight. DESIGN VERSATILITY Panels are standard 26- or 24-gauge in either acrylic coated Galvalume or galvanized (G-90 coating) with painted Butler-Cote 500 FP, (70% Kynar) Kynar 500/Hylar 5000 finish. Maximum spacing between the secondary roof structural members is /16 on the roof slope. The Butlerib II roof system, with the exclusive 1-1/2 high corrugation, is designed to meet most live loads and wind loads for any roof configuration. This roof panel, with its tall corrugation, is one of the strongest standard ribbed panels in the industry. The minimum roof slope for application of the Butlerib II roof is 1/2:12 inches. Butlerib II Panel to Structural Member Detail Y306. Butlerib II Panel Corrugations Detail Y307. Other Manufacturer s Panel Corrugations The maximum panel run for a continuous run of punched panels, on the same slope is 180. Optional unpunched panels are available, but not recommended for panels on the same slope running more than 80 continuously. The maximum recommended panel length is 40. WIND UPLIFT The Butlerib II roof system carries the highest ratings awarded for wind uplift and are listed below: 1. UL-Class 90 Rating (UL Test 580) 2. Factory Mutual (FM4471) Approved I-90 Windstorm Rating In many locales, a wind rating will result in lower insurance premiums for a building.

116 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 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. The Retrofit Roof Panel Clip is installed through the existing roof panel into the existing building purlin. 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. If the existing roof was installed off module, then the Low Profile MOM system should not be used as the existing panel ribs may interfere with the installation of the new roof panel clips. HIGH PROFILE METAL OVER METAL ROOF SYSTEMS The High Profile MOM minimum application is to roof slopes of 1/4:12 inches or greater. This system is designed to allow for the installation of the MR-24 and VSR II roof systems over an existing metal or other roof with major corrugations higher than 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 heel height is 0 inches. RETROFIT CONSTRUCTION GENERAL 08/02/

117 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, etc. to fill the holes made in the roof when fasteners are pulled out. RETROFIT CONSTRUCTION FASTENER CALCULATIONS 08/02/

118 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 = pounds The test pullout value is 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 the 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 that 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. RETROFIT CONSTRUCTION FASTENER CALCULATIONS 08/02/

119 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 is 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 of 90 mph exposure B) of a typical roof attachment fastener is as follows: Local Building Code Wind Load: Required wind uplift load =14.2 psf (determined for the IBC 2003 for a field of roof zone) Factor of Safety = 3.0 Secondary structural spacing = 5.0 feet Required uplift resistance = 14.2 psf x 3.0 x 5.0 feet = 213 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 = 213 lbs/ft Roof Project Test Pullout Value Required Fasteners lbs/fastener 213/320 = 0.67 per ft. or 1 every 18 inches lbs/fastener 213/450 = 0.47 per ft. or 1 every 24 inches lbs/fastener 213/600 = 0.36 per ft. or every 33 inches lbs/fastener 213/150 = 1.42 per ft. or every 8.5 inches RETROFIT CONSTRUCTION FASTENER CALCULATIONS 08/02/

120 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 Gage Steel Bar (2) Joist Deck Plywood Construction (embedment depth) Supplier Fastener Description Fastener Length /2 3/ /4 1-1/4 Buildex Roofgrip 1-5/ Screw to 12 Tapcon 3-3/4 1/4 HWH to 5 1/4-10 1, Type 17 1/2, / HWH Teks/5 1/4 x 14 3/ HWH Teks/3 1/4 Type 3/4 to B 8 Fabco 1/4 5 to Insulfixx 12 #14 Type A 1 to /32 7/8 to Scrubolt 5 3/8 1 to Scrubolt /4 Confixx to 6 (1) If no number is shown, use is not recommended. (2) 1/8 minimum thickness. IMPORTANT NOTES (embedment depth) 1 1-1/4 1-1/ 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. RETROFIT CONSTRUCTION FASTENER CALCULATIONS 08/02/

121 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 14.2 psf ft. = 213 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.

126 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 pre-punched 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 During The Slope Build-Up system requires that a 3 minimum layer of 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.

127 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.

128 B. Base Z-purlins parallel to top Z-purlins are used when existing secondary structural members run perpendicular to the NEW eave. (Parallel installation.) SLOPE BUILD-UP SYSTEM GENERAL 08/02/

129 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 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 coal tar 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 GENERAL 08/02/

227 NEW CONSTRUCTION ROOF SYSTEM APPLICATIONS BY BUTLER GENERAL INFORMATION New Construction involves using Butler roof products on new non-butler buildings. 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 pre-punched 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 pre-punched 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 pre-punched 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 electricpowered hydraulic Bar Joist Top Chord Puncher may be leased from Butler s Roof Runner Department for this purpose.) 3. All other bar joists may have their roof panel 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 pre-punched 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. 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. NEW CONSTRUCTION APPLICATION GENERAL 08/02/

228 VSR II ROOF SYSTEM The VSR II 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 deterioration due to stress buildup. Top elevation of the eave roof structural must be in the same roof plane as the flat of the VSR II roof panel. (Refer to VSR II 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 1/2 for short moveable clips or 1-1/4 for tall moveable clips. The VSR II 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 II 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 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. 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. NEW CONSTRUCTION APPLICATION GENERAL 08/02/

239 GENERAL INFORMATION Below is a summary description of the various roof system accessories. Each is described further in the pages following. 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 1/4 to 13 outside diameter pipe sizes. 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 chaindriven, 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. It is designed for installation at the ridge on roof slopes of 1/2:12, 1:12 and 4:12 inches. The gravity ventilator is used with the Butlerib II roof system only.

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.

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 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 150 MPH or more. 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, onsite full time during roof installation, can provide Butler-issued photo certification I.D. upon request. Under other warranties, the owner is left to find the responsible party and enforce the terms of the warranty. ROOF WARRANTIES GENERAL 08/02/

266 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. ROOF WARRANTIES GENERAL 08/02/
