TABLE 1504.1.1 CLASSIFICATION OF STEEP SLOPE ROOF SHINGLES TESTED IN ACCORDANCE WITH ASTM D316 OR D71581 MAXIMUM BASIC WIND SPEED, V, MAXIMUM ALLOWABLE STRESS ASTM D7158ᵃ ASTM D3161 FROM FIGURES 1609.3(1)-(12) OR DESIGN WIND SPEED, Vasd, FROM CLASSIFICATION CLASSIFICATION ASCE 7 (mph) TABLE 1609.3.1 (mph) 110 85 D, G or H A, D or F 116 90 D, G or H A, D or F 129 100 G or H A, D or F 142 110 G or H F 155 120 G or H F 168 130 H F 181 140 H F 194 150 H F For SI: 1 foot = 304.8 mm; 1 mph = 0.447 m/s. a. The standard calculations contained in ASTM D7158 assume Exposure Category B or C and building height of 60 feet or less. Additional calculations are required for conditions outside of these assumptions. 1504.5 Edge securement for low-slope roofs. Low-slope built-up, modified bitumen and singleply roof system metal edge securement, except gutters, shall be designed and installed for wind loads in accordance with Chapter 16 and tested for resistance in accordance with Test Methods RE-1, RE-2 and RE-3 of ANSI/SPRI ES-1, except basic design wind speed, V, shall be determined from Figures 1609.3(1) through 1609.3(12) as applicable. 123
