Roof Sheathing And Fascia Board

Where should roof drip edge flashing be placed.

Roof sheathing and fascia board.

Vinyl is becoming more popular because it requires little. On my shed my sheathing does not protrude actually how both my house and shed are done is a 1 x 6 house 1 x4 shed fascia is installed to end of rafters then 1 x 1 1 2 is tacked onto the fascia at the top. Click to enlarge any image our illustration above shows proper placement of the roof drip edge atop the roof sheathing before installation of roofing felt or ice and water shield and spaced a bit away from the fascia. Then i do a metal drip edge to cover it all.

The framing continues with roof sheathing. This is a known issue that is directly caused by capping over the fascia instead of doing a proper job and replacing it. Most of the roof runoff is going off the roof not down the fascia board. I also found an online standard example of fascia also flush with the surface of the sheathing bevelled to meet the pitch and rafter tails.

They don t explain fascia subfascia roofing very well. The plan i consulted had 1x6 fascia flush with the surface of the sheathing rafter tails angled to match the bird s mouth cut and pitch of the roof. 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. 1 by 8 boards commonly used on the eave and rake overhangs when soffits will not be installed rather than as roof sheathing.

The roof sheathing comes down and ends on top of the 1 x fascia. The inch thick boards extend from the eaves just past the exterior walls where they butt up against the plywood roof sheathing. Mark the thickness of the roof sheathing 1 2 in. The boards are more attractive when viewed from underneath than rough plywood.
