With a person on each end, fold the underlayment in on itself, sticky aspect out. Try to push it down into the crease of the valley as tightly as potential. If this self-stick ice-and- water underlayment bridges either side of the decking, leaving a gap underneath, it might tear once you install the metal valley flashing.

Line up the underside of the first row of shingles with the bottom fringe of the starter row, making sure the seams are staggered. With that row full, you will need to determine the reveal (the portion of the shingle that is not covered by the one above it). Standard reveals differ between 5 and 6-half in. Whatever the reveal is supposed to be, snap a horizontal line that distance from the highest of the primary row of shingles . Cut the flashing back to the peak along each crease.

Cover the remainder of the roof with No. 15 asphalt-saturated felt underlayment (some codes could require No. 30). Each layer overlaps the lower one by no less than 2 in. Follow this step by nailing drip edge along rakes , on top of the underlayment. As you … Read More

The shingles are woven together from either side of the valley. The advantage of a woven valley is that it does not leave an exposed flashing, which results in a cleaner look. The downfall is that leaves and twigs don’t get washed away as simply, which can trigger little water dams. This is very true for roofs with low pitches.

Use a tin snips to cut the drip edge to dimension. Make positive this row has a slight overhang (1/4 to three/8 in.) past the drip edge. The starter course protects the roof by filling in the spaces beneath the cutouts and joints of the next row of shingles.

The adhesive on the starter course seals the tabs of the primary full course. Install the top ridge cap so the prevailing winds blow over the overlaps rather than into them. If wind is not a difficulty, begin at both aspect, or begin at each side and finish in the center. Rip the highest half off the final ridge cap shingle, and nail through the face of it with two nails on the ends of every side. Weave the step flashing and the roof shingles together so that water can’t get underneath the shingles.

If the overhang is greater than a foot, minimize some off and use the rest elsewhere. Another means of dealing with valleys is to make use of the “weave” method, which we don’t cover on this story.
