The mechanical fastener spacing is as follows: Zone 41 (37 psf) — 8" o.c. in the 4" lap and three rows, staggered, spaced 8" apart @ 8" O.C. Zone 42 (62 psf) — 6" o.c. in the 4" lap and three rows, staggered, spaced 6" apart @ 6" o.c. Zone 43 (93 psf) 4" o.c. in the 4" lap and three rows, staggered, spaced 4" apart @ 4" O.C. All calculations are based on RAS-117 and the information contained in CertainTeed NOA 20-0110 expiring 06/19/2023. The cap sheet will be CertainTeed Flintlastic GMS. A portion of the main house will have a sloped metal roof installed. The metal roof will be a DM Class 1000, 1" nailstrip, 26 ga. galvalume coated steel roof panel, 16 wide, with 1" snap seam. The design pressures for the sloped metal roof are 37 psf in zone 1, 62 psf in zone 2 and 93 psf in zone 3 for a "C" exposure, less than 15 foot tall average roof height. These fastening patterns will meet the structural criteria of the 2020 Florida Building code, 7'h. Edition, with a "C" exposure during a 170 mph.it, 132 mph asd wind event.
