What Size of Roof Nail is Used In Construction Industry

 The commonly used roof nail sizes in construction are as follows:
- 1-1/4 inch (32 mm): This size is widely utilized and suitable for asphalt shingles, cedar shingles, and lightweight roofing materials.
- 1-1/2 inch (38 mm): Slightly longer nails of this size are typically used for heavier roofing materials such as slate, tile, or thick wood floors.
- 2 inch (50 mm): Longer nails of this size are sometimes employed for ultra-thick or multi-story roofs, such as re-roofing over an existing roof.
- 3/4 inch (19mm): Shorter nails of this length can be used to secure roof bedding, tar paper, or house packaging.

The selection of nail size is based on the thickness and type of roofing material, as well as the required penetration depth into the roof panels. While longer nails provide better holding force, they should not penetrate the roof panels. Local building codes often specify minimum nail size requirements for different roofing applications.

In addition to nail length, nail diameter is also a crucial factor. Common roof nails range in diameter from sizes 11 to 14 (approximately 0.120 to 0.080 inches). Larger diameter nails offer greater drawing resistance.
