Roof Sheathing Peak

It must be completed at the very end of the shingle run to overlap the uppermost shingles and form a weatherproof.

Roof sheathing peak.

Start the sheathing at the eaves and work your way up to 1 inch from the peak. How should the sheathing meet at the roof peak when there will be no ridge vent. Step 4 cut overhang. I have seen two thoughts.

This is a simple pitched roof line with ridge beam and rafters attached with slope hangers. Snap a chalk line along the overhanging sheets along each side of the roof aligned with the edge of the last rafter and trim off the excess sheathing with a circular saw. Nails size 8b should be installed every 6 inches on edges and every 12 inches in the center area. Leave a slight gap as if the sheathing was cut a little short and install the sheathing to a matching edge no gap.

Check for alignment and end support as you go. Preparing the peak capping a roof is the last thing done during a roofing project. For safety temporarily nail a 2 x 4 toe board horizontally across the lower panel of sheathing to brace yourself against as you add the second and subsequent courses of sheathing.
