Dormer Construction: Framing the Slope

Today was rather annoying.

I had expected to completely finish framing the dormer and installing all the rafters today, but instead we only managed to frame the perimeter of the sloping roof. It turned out to be a lot trickier than any of us expected - part of this was due to  the geometry and the other part was due to the extremely poor shape of the hip rafter (the sloped corner beam) of the original roof . In preparation for doing the rafters, I removed the ridge tiles (triangular shaped tiles that protect the ridge/edge) and realized that we should reinforce this beam where we were building the dormer.

We then spent the rest of the day cutting intricate joints to get everything to fit together correctly...

Looking good...but...
We soon realized the hip rafter was in bad shape and needed reinforcing
We added an extra piece of wood to reinforce the hip rafter. This was really tricky because it intersected many other beams at the top. These joints had to be cut by hand

Finally - everything back together
