How To Sheath A Roof Ridge

I have seen two thoughts.

How to sheath a roof ridge.

Necessarily at the edge of the sheathing. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame. Roof sheathing is a lot more than just flat panels onto which shingles are attached. Holes drilled in roof sheathing for ventilation roof diaphragm action is maintained.

When one slope is completely sheathed pop a chalk line down any slope edge as in a hip roof that needs to be cut at an angle. The typical thickness range for sheathing is 3 8 to 3 4 inch. A tapered piece of sheathing can be cut to fill in at the eave if necessary. How should the sheathing meet at the roof peak when there will be no ridge vent.

Nailing accuracy is crucial along this member. During a hurricane the strength of the sheathing on the roof can greatly impact the homes ability to weather the storm. I noticed when the job was all done that they had left a gap in the ridge of the gambrel roof sheathing of about 3 inches and applied the asphalt shingle cap directly over it. Leave a slight gap as if the sheathing was cut a little short and install the sheathing to a matching edge no gap.

Method for maintaining a continuous load path at the roof ridge by nailing roof sheathing. The connection between the roof sheathing and the structure is a vulnerable point that is known to fail during a hurricane. Sheath one slope of the roof at a time ripping the top course to the needed width at the ridge. Tighter nail spacing is recommended 4 inches on center maximum.

This is a simple pitched roof line with ridge beam and rafters attached with slope hangers. Osb is lightweight relatively inexpensive and strong enough to resist bending or breaking should someone walk on the roof. Never attach roof sheathing with staples. The roof s sheathing helps to keep the roof trusses or rafters properly spaced and is the strength that holds.

8d ring shank nails should be used instead. They pre fab all the walls and build the shed on site. In the u s roof sheathing is almost always composed of wood usually osb oriented strand board or plywood. Having virtually no framing experience i purchased a 10 16 cedar shed from shedsusa.

Keep these tips in mind when roofing in hurricane areas.
