Hi all,
I have an room addition with a gable roof that is offset about 8 inches from the existing roof (i.e., lower than the roof on the rest of my cabin). The existing gable exterior is T1-11 siding. When I install flashing at the point where the new roof meets the old gable, do I caulk around the point where the exposed portion of the flashing where it meets the gable, or is it better to cut a kerf in the T1-11 gable, insert the flashing into the kerf, and caulk?
Something like this:
