Not quite sure that I understand your description of the question, but all window headers are framed conventionally. We have a dual pitched roof. The main roof slope is 10/12, which is steep and 6/12 for the flared portions. Because of the overhang depth, the roof edge gets low. At the windows, we flared the roof to a 6/12 pitch which raises the roof and eave to a normal height at is relates to the window.

Thanks,
