Intersecting Roofs Different Pitch

With this method and a framing square you can join roofs of different pitches and still have perfectly aligned equal width soffits a builder describes how he uses a framing square and full scale layout to solve this tricky problem.

Intersecting roofs different pitch.

A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. The roof has two valleys of different pitches of which the lines n l k are the seats or runs. We wanted to make the porch roof as steep as possible while keeping the peak of the roof below the wall to roof intersection at the top of the shed roof. Does anyone know of a tutorial for different intersecting roof pitches.

I am sure someone has had this issue before but when i submit a question for different intersecting roof pitches in the video library nothing comes up. After a taking some measurements and doing a bit of ciphering we established that the steepest pitch we could use on the porch roof was 4 in 12. Their steep pitch also lets water run off easily ultimately reducing the need for additional waterproof roof treatments that lower pitched roof types require. Explore framing complexities that result when roofs of two different pitches intersect.
