In the weeks (months) since my last post, really quite a bit has happened, although, on this end it seems like it's been very slow. I've been doing as much work on the addition by myself as I can. That, of course, goes fairly slowly. By May I had gotten most of the framing up. At that point I realized I needed help.
The few rafters over the cantilevered part of the roof were not something I could set myself. The fascia boards will also help support the cantilever and I certainly couldn't get those up in place by myself. So I hired some pros from Burkey Construction to help me for 2 days. Chuck, Mike, Ron, and me got the roof framed, the walls sheathed, the roof sheathed, shingled, and the big window installed in 2 days.
The "box" hanging on the wall in the photo above is where the kitchen window will be. As I was framing, Jan asked if we could have a deep sill on the window over the kitchen sink for plants. Sure.
So that's what that bump-out is for. The window isn't there yet because it is still in the old wall inside. It was our biggest window looking out of our little apartment. It will be removed to make the new opening between the old space and the new one.
After the guys left, I installed the other windows and sealed the roof/metal wall connection. The corrugated metal wall presented a big problem for me here. I couldn't do a conventional flashing detail because of the corrugations and foam insulation on the inside. So here's what I did, and so far it's working. I filled the gaps between the new roof and wall with spray foam. Then I trimmed all the bulging foam flush with the roof and brushed on a water proofing sealer. The kit I bought came with a roll of fiber to embed into the sealer for strength. Followed by another coat of the sealer. I don't see this as a permanent fix, but if I keep it maintained, I think it will last. I'll probably just have to re-coat periodically. Maybe a better solution will come to me, but for now, it's keeping things nice and dry.
