Nails and Nailing Shingles/Shakes

31. Each roof shingle/shake shall be secured with two-driven, corrosion-resistant nails. (Specify size).

32. Use 3d "box" nails for new roof with 16" (406.4 mm) and 18" (457.2 mm) shingles.

33. Use 4d "box" nails for new roofs with 24" (609.6 mm) shingles.

34. Use 4d "box" nails for over-roofing with 16" (406.4 mm) and 18" (457.2 mm) shingles, and for hips and ridges.

35. Roof shakes shall be secured with corrosion resistant, hot-dipped, zinc-coated nails or aluminum or stainless steel nails -type 304 or 316. Nails shall be long enough to penetrate sheathing at least 1/2" (12.7 mm) (3/4" (19.05 mm) per UBC). 6d nails are usually adequate, but longer nails shall be used as shake thickness or weather exposure dictates.

36. If staples are used they shall be stainless (type 304 or 316) or aluminum. In drier climate regions, having a climate index or less than 35 as indicated by the USDA Forest Service, good quality electro-galvanized staples, conforming to ASTM A641, have proven satisfactory for applying untreaded shakes or shingles. Blue steel fasteners should not be used.
