Roof Sheathing Should Be Installed

This can be done with a straight piece of lumber 6 feet to 10 feet long or a long carpenter s level.

Roof sheathing should be installed.

In areas where the wind speed is greater than 130 mph nails for attaching the roof sheathing to intermediate supports should be spaced 6 inches on center for at least the first 48 inches from the ridges eaves and gable end walls. 24 inches on center the actual distance between panel supports measured along the slope is greater than the truss spacing. Local roof repair contractors inspect the sheathing during maintenance repairs and especially during roof replacement. Trusses or rafters should be shimmed as necessary to provide a level nailing surface.

Never attach roof sheathing with staples. Then its condition is inspected. 8d ring shank nails should be used instead. Tongue and groove installations require thicker material at least 1 1 2 inches thick as they don t often require insulation and often double as the ceiling.

If the top chords of trusses or rafters are warped or bowed install blocking to straighten. Sheathing is installed perpendicular to roof trusses. There should be at least 3 8 inch of space between the fastener and the panel edge. The first thing we check is the thickness of the material used.

This can cause a problem because while the hip trusses maintain their normal spacing e g. Sheathing should be a minimum of 19 32 inch thick. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame.
