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.

Intersecting roofs different pitch.

Does anyone know of a tutorial for different intersecting roof pitches. 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. 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.

To find the length of the valley rafter on the right side of the front gable on the line k l square up the rise of the roof from l to m connect m with k and we have the length of the valley after. Explore framing complexities that result when roofs of two different pitches intersect. Their steeper pitch also evokes a more minimal design and the materials used to make a skillion roof including metal tend to be slick unlike the bulkier shingles or tiles of a classic. I have a farmhouse design i am working on where i want my main body roof to be 6 12 and a couple gables facing the front to be 12 12.
