Intersecting Roofs Different Pitch

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.

Intersecting roofs different pitch.

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. The roof has two valleys of different pitches of which the lines n l k are the seats or runs. 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. Explore framing complexities that result when roofs of two different pitches intersect.

A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. Their steep pitch also lets water run off easily ultimately reducing the need for additional waterproof roof treatments that lower pitched roof types require. 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 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.
