Notes for Table 4: 1.For attachment systems not listed in the table for 19/32-inch-thick (15.1 mm) sheathing use the allowable aerodynamic uplift resistance from the table for 15/32-inch-thick (11.9 mm) sheathing. 2.Fasteners shall have a minimum edge distance of 11/2 inches (38.1 mm) from the head of the tile and located in the pan of the tile to obtain the values in Table 3. 3.Ring shank nails shall be 10d ring shank corrosion-resistant steel nails with the following minimum dimensions:(3-inch long (76.2 mm), 0.283-inch (7.2 mm) flat head diameter, 0.120-inch (3.0 mm) undeformed shank diameter or 0.131-inch (3.3 mm) screw diameter). 4.Smooth or screw shank nails shall be 10d corrosion-resistant steel with the following minimum dimension: (3-inch long, (76.2 mm) 0.283-inch (7.2 mm) flat head diameter, 0.120-inch (3.0 mm) undeformed shank diameter or 0.131-inch (3.3 mm) screw diameter). 5.Screws are #8 course threaded, 2.5-inch-long (63.5 mm), corrosion-resistant steel wood screws conforming to ANSI/ASME B 18.6.1. 6.The fastener hold nearest the overlock shall be used when a single nail or screw is required. The fastener hole nearest the underlock and the fastener hole nearest the overlock shall be used when two nails or screws are required. 7.When using eave and field clips, attachment of the tiles is accomplished by a combination of nails and clips. Tiles are nailed to the sheathing or through the battens to the sheathing with one or two 10d corrosion-resistant nails, (Notes 2 and 3 above). Additionally, each tile is secured with a 0.060-inch-thick (1.5 mm) and 0.5-inch-wide (12.7 mm) clip which is secured to the plywood sheathing or eave fascia, as appropriate, with a single nail per clip. The nail shall be placed in the hole closest to the tile for clips having more than one nail hole. The following clip/nail combinations are permitted: a.Aluminum alloy clip with 1.25-inch (31.8 mm) HD galvanized roofing nail (0.128-inch (3.3 mm) shank diameter). b.Galvanized steel deck clip with 1.25-inch (31.8 mm) HD galvanized roofing nail (0.128-inch (3.3 mm) shank diameter). c.Stainless steel clip with 1.25-inch (31.8 mm) HD galvanized roofing nail (0.128-inch (3.3 mm) shank diameter). 8.Field clips and eave clips are to be located along the tile where the clip’s preformed height and the tile’s height above the underlayment are identical. 9.The allowable aerodynamic uplift moments include a generic restoring gravity moment of 6.5 ft-lbf for a direct deck and a restoring gravity moment of 5.5 ft-lbs for a batten installation. 10.Counterbatten values not included. For attachment systems not listed in table for 15/32-inch-thick (11.9 mm) sheathing, use allowable aerodynamic uplift moment from table for 15/32 – inch-thick (11.9 mm) sheathing. 302 E Santa Clara Ave 9/25/2024
