Roof Sheathing Does Not Overlap Fascia Board

If the overlap is too short fix it by placing drip edge under the first row of roof shingles and be sure that the exterior edge is reaching over the gutter.

Roof sheathing does not overlap fascia board.

In this video i trim my truss tails by snapping a chalk line drawing a plumb line down from that line and then using a circular saw to cut them off. Then i do a metal drip edge to cover it all. Smooth the caulk bead with your finger and begin caulking the joint between the fascia board and the soffit also. When sheathing a roof the first step is to snap a line so that the first row goes on straight.

4 reduced roof tile overhang by capping over the boards the guttering will be set slightly further away from the roof tiles this may cause rain water to run behind the gutter rather than into it. This is a known issue that is directly caused by capping over the fascia instead of doing a proper job and replacing it. If the gutter is lower than the bottom edge of the drip edge install flashing behind the drip edge and over the back edge of the gutter to remove the gap. But if you snap it at 40 inches then the sheathing will not project over the subfascia or true fascia.

Gravity can be your buddy. This opens the door to the possibility of water damage by letting gravity work against you. On roofs with no eaves overhang or soffit proper installation of drip edge proud of the fascia board at the wall top is very important to avoid water damage to the building walls below. If the gutter is not secured snugly against the fascia or if the gutter was installed atop rather than under the drip edge you ll get this problem.

Start at the end of a fascia board and caulk the corner edge where two boards meet.
