Dormer Window Installed

I've installed the window in the right-front dormer. I needed to do that before I could remove the work platform so that I can finish the shingles in front of the dormer.

A Few More Shingles

I'm working my way down between the dormers on the front now.

More Shingling

I've shingled one side of the second front dormer and now I'm working my way down the roof and in between the dormers.

Shingles are installed so that they overlap each other, and they're designed with an adhesive on the back so that they'll stick together where they're overlapped. This helps prevent them from getting blown off in the wind as well as preventing water from getting underneath. In hot weather, they'll start to stick together within about 15 minutes, and they're difficult to separate once that happens.

When I finish doing a section of shingles, I stick shims under the edges of the bottom two rows. The shims keep the shingles separated just enough so that they don't stick to the roof or to each other. This is important because when I'm doing the next section of shingles below, I need to be able to lift these edges up so that I can nail the top row of the next section in place. When I'm done nailing that top row, I pull out the shims and everything sticks together like it's supposed to.

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.
