How Many Nails Should Be Used To Nail Roof Sheathing

I m adding a deck with roof to the side of my house.

How many nails should be used to nail roof sheathing.

Each of these factors plays a role in determining how many nails you ll need to use per board during roof sheathing application. Ansi national design specification nds chapter 12. Spacer type panel edge clips are available from some manufacturers. There are different kinds of roofing nails made of different materials and in various sizes.

Roofing nail should have a barbed shank until the head which eliminates nail pops blow offs and roof leaks. I ll be using 3 8 plywood sheathing on 2x8s with 16 centers. Boards require a minimum of two nails per truss while sheathing requires six nails due to face width and nail spacing. Roof sheathing panel spacing hints.

The problem exists because nail sizes and spacing used to attach the sheathing to the roof s structural members rafters or trusses do not provide enough strength to keep the sheathing on. Because of this concept many building standards groups specify that only nails and staples are to be used for wood structural panel attachments in wall applications. I read something that said the sheathing should be nailed on with 8d nails where i was planning to use 1 1 2 ringed plywood nails. Use a 10d box 0 128 inch by 3 inch nail as a spacer to gauge 1 8 inch edge and end spacing between panels.

A structure s roof truss spacing can vary from every 12 to 24 inches.
