Hello everyone. Before I purchased my house there was a sun room addition that was built onto it with a flat roof. Just recently, the roof started to leak through into my sun room. I really dislike the concept of having a roof with virtually no pitch, so I've decided to rebuild a better, pitched roof in its place. My issue is how to lay it out.
I'm going to attach a couple images I made that show both an aerial and side view of the roof in question. Please excuse my amateur paint skills!
Should I attach a ridge board to the wall underneath the window and run rafters from it? Do I need to place something underneath the ridge board so it can hold the weight of the rafters? How big do the rafters and ridge board have to be? I figured 2x6 for the rafters since it appears to be standard, but I don't know how to gauge the ridge board size. I've tried my best to research about roofing, but I have virtually no hands on experience with it so it's hard to visualize everything.
