Shingling Progress

I've been working on shingling the main roof this week. As I talked about in earlier posts; I'm using a top-down method of shingling. Here's a link to an article about it: Shingling From The Top Down.

When you shingle around a chimney, you put the shingles on the up-slope side of the flashing on top of the flashing. On the down-slope side; the shingles sit underneath the flashing. By keeping everything overlapping in that manner, water doesn't have a chance to get underneath anything.

The photo below shows the finished closed valley I mentioned in an earlier post. When shingling the dormer, the shingles that cross the valley (the area where the two roof planes meet) extend about 16" up onto the main roof. The shingles on the main roof are then installed on top of the ends of those dormer shingles, then trimmed off about 2-3" away from the centerline of the valley.
