Roof Sheathing Over Fascia Board

Where should roof drip edge flashing be placed.

Roof sheathing over fascia board.

Run fascia the thickness of the plywood higher than the fly rafter on the gable and flush on the sub fascia. I install the fascia flush with the top of the sub fascia. Starting with how to place the first row of sheathing we cover fastening methods the use of h clips stagg. Gable end detail overhang cut and then rebuilt to hide the thickness of the over roofing rigid insulation.

Installing the fascia before sheeting the roof solves a lot of problems. Roof edge detail overhang extended to hide the thickness of the over roofing rigid insulation. This would add another 3 4 to the thickness. Now that i ve modeled what i was going to build i decided i need a piece of molding to break up the plain look of just the fascia trim plank.

But if you snap it at 40 inches then the sheathing will not project over the subfascia or true fascia. We go in depth on how to install roof sheathing. This opens the door to the possibility of water damage by letting gravity work. Installed a new fully adhered membrane to the top of the old board sheathing prior to adding all that rigid insulation.

This is to just enough to cover the 3 4 x6 actual fascia. 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. Draw a full scale mockup and snap a line with fascia in kind when sheathing a roof the first step is to snap a line so that the first row goes on straight. Chalk your line up the rake 48 from the point where fascia meets sub fascia.

Most of the roof runoff is going off the roof not down the fascia board.
