Make a pencil mark on the sheathing where a horizontal line would meet the exterior wall.

Attic ventillation consists of two gable vents (maybe 12"x18") on a 28 x 32 roof. To determine the number of squares of soffit required, measure the under-eave areas and multiply the length by the width for each overhang. Add up the total of all overhangs and divide the total by 100 to determine the number of squares.

. Secure the underlayment in place with staples or nails. Click on this link for more ideas for your next construction project and roof framing repairs.

Make sure the outer edge extends over the gutter. 1–22.

Not enough overhang at the bottom will cause the water to fall between eavestrough and fascia. Add up the total of all overhangs and divide the total by 100 to determine the number of squares.

Make a 1- to 2-in. yahoo.

Once you’re satisfied that the fascia will go on straight, align the bottom edge of a 2-foot level with the level cut of a rafter tail.
Overlap the other pieces of eave strip by at least 1” and nail them in place.

Shingle the addition roof, letting the new shingles fold through the valley center and onto the old roof deck by at least 1 ft. Re-lay the shingles you removed from the existing roof. .

2. If it doesn’t, pull the drip edge out slightly from under the shingles. It’s common practice to set trusses and rafters to hang past the wall to make the desired roof overhangs, but the ease of sealing the transitions from the roof to the vertical surface of the wall makes creating a tight building envelope. To determine the number of squares of soffit required, measure the under-eave areas and multiply the length by the width for each overhang. . .

This summer we will be repairing water damage to the wall directly beneath this gable along with re-roofing and re-siding.

. Nail lumber to the rafters so twice the overhang length is in the roof.

We decided to use oversized 8-by rough-cut posts and beams in the design.

Once you’re satisfied that the fascia will go on straight, align the bottom edge of a 2-foot level with the level cut of a rafter tail.

Rip-cut the starter strip or starter pieces so that they butt up against the second course of existing shingles and are even with the front edge of the existing roofing.
