One layer of minimum '/2inch-thick (12.7 mm), water- resistant core gypsum sheathing, complying with ASTM C 79, is installed over the counterbattens using 4d drywall nails or equivalent. The gypsum sheathing joints must be tightly butted. As an alternative to 1/2 -inch -thick (12.7 mm) gypsum sheathing, two layers of Elk Corporation's Versashield underlayment (ER -5627) may be used. In accordance with Section 1510.4 of the IBC, Section R907.4 of the IRC, and Section 1510.4 and Appendix Section 1516.3 of the UBC, when the steel panel roofing system is installed over wood shake or wood shingle roofs, the '/2inch thick (12.7 mm), water-resistant core gypsum sheathing, described above, installed over the counterbattens and covering the entire surface of the existing wood roof, or two layer of Elk Corporation's Versashield underlayment (ER -5627), satisfies the requirements of Section 1516.3 and Table A -15-A of the UBC Appendix. Steel roof panels so installed over existing roofs comply with UBC Standard 15-2 and are Class A fire -retardant roofing assemblies. 4.6 Wind Resistance: For jurisdictions adopting the IBC, IRC, BNBC and SBC, the maximum allowable wind uplift pressure is as shown in Table 2 of this report. The balance of the installation must be as described in Section 4.0 of this report. Recognition in jurisdictions adopting the UBC is limited to Exposure B areas where the basic wind speed does not exceed 70 mph (112.70 km/h), the building height is less than 40 feet (12 192 mm), and installation is in accordance with Section 4.4 or 4.5 of this report. 4.7 Structural Diaphragm: Structural roof diaphragms using the roof panels described in this report must be constructed as follows: Nominally 1 -inch - by -6 -inch standard grade, or better, Douglas fir sheathing or sheathing of other species having a specific gravity of 0.50 or greater, spaced a maximum of 91/2 inches (241 mm) on center, must be nailed to framing in accordance with the applicable code. Framing members must be spaced a maximum of 24 inches (610 mm) on center. Wood battens, counterbattens and the roofing panels are installed over spaced sheathing in accordance with Section 4.1 of this report. Fasteners attaching the counterbattens to the roof must penetrate into the framing members and must be within 6 inches (152 mm) of the counterbatten ends. The resulting diaphragm has an allowable shear of 180 Ibf/ft (2628 N/m) and is equivalent to 15/32 inch -thick (11.9 mm) wood structural panels complying with DOC PS 1 using 8d common wire nails over nominally 2 -inch wood framing members in an unblocked diaphragm, with nails 6 inches (152 mm) on center at the edges and 10 inches (254 mm) on center in the field of the panel. The maximum aspect ratio is 4:1. Diaphragm deflections, based on using 75/32inch-thick (11.9 mm) wood structural panels complying with DOC PS 1, must be estimated by using the following equation: A = 5vL318EAb + vL/59600 + 0.003384L + 7-(AA/2b For SI: A = 381 vL3/2EAb + vL/2347 + 0.086L + 25.42:(AA/2b where: A = Area of chord cross section [(in2 (mm2)]. b = Diaphragm width [ft (mm)]. E = Elastic modulus of chords [Ibf/ft2 (kPa)] (per AF&PA-NDS). L = Diaphragm length [ft (mm)]. v = Maximum shear due to design loads in the direction under consideration [Ibf/ft (N/m)]. A = Deflection [in. (mm)] F(AA = Sum of individual chord -splice slip values on both sides of the diaphragm, each multiplied by X, the splice distance to the nearest support. Calculations for diaphragm deflection must account for the usual bending and shear components as well as any other factors, such as nail deformation, that will contribute to the deflection. 4.8 Canyon Shake, Barrel Vault and NB Tile Panels -Direct Application to Roof Deck (No Battens): The panels may be installed directly to deck without battens as a new roof covering assembly. The sheathing must be minimumt5/32inch-thick (12.7 mm) wood structural panels complying with DOC PS 1, covered with underlayment in accordance with Section 4.3 of this report. The minimum roof slope must be 3:12 (25 -percent slope). The panels must be fastened to the sheathing in accordance with Tables 1 and 2 of this report. 5.0 CONDITIONS OF USE The Gerard steel roofing panels described in this report comply with, or are suitable alternatives to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 The panels must be manufactured, identified and installed in accordance with the applicable code, this report and the manufacturer's published installation instructions. 5.2 Prior to reroofing with the panels, the existing roof must be inspected and approved by the code official, as required by the applicable code.
