Does Roof Sheathing Overhang Fascia

In most cases if the shingles go past the drip edge about 3 4 of an inch the shingle edge will break the surface tension unless your roof has a shallow pitch then the water will reach the drip edge and if drip edge is tight to the facia board it will run down the fascia so as added insurance leave space between the fascia and drip edge.

Does roof sheathing overhang fascia.

This opens the door to the possibility of water damage by letting gravity work against you. Make sure it is square level etc. The exposed edges of the 3 layers of rigid insulation are no longer exposed. But if you snap it at 40 inches then the sheathing will not project over the subfascia or true fascia.

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. I ve seen it done both ways but i like it to overhang the fascia. Use your speed square on the fascia board and run the sheathing down to that. With a flat shed roof the roof simply extends past the wall plate to provide an overhang.

Most houses have fascia running along all of the eaves the overhangs at the bottom of the roof. Use 2x6 for fascia board. Homes that have gable roofs the classic roof style with triangle topped walls at each end also have fascia running up the gable ends of the roofline. Don t overhang the sheathing at all.

Soffits appear anywhere a roof extends beyond the walls by more than a few inches. Because this style of a shed has a flat roof it can facilitate a wider overhang which is ideal for storage. 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 you re putting a drip edge and ice and water shield on that should take care of any possibility from water getting inbetween the ply and the fascia detail.

When sheathing a roof the first step is to snap a line so that the first row goes on straight.
