A shed style was the best solution for this porch roof because of restrictions placed by the existing second-story windows. It would also have been difficult to match the pitch of the existing gable roof next to the porch.

When working with brick veneer, the author hangs the porch rafters from a structural double LVL ridge beam (shown before hanger installation).
