What design problem do you see with this roof?
a. No flashing at the transition from upper roof to steeper lower roof.
b. Poor drainage path between the bottom of the valley and the edge of the roof.
c. Double front gables don't match the main roof.
d. Minimal roof overhang will not protect wood shingles on the gable from weather, accelerating their deterioration. This is form with minimal regard for function.
