I had a new roof put on our 1930’s cape style house during a renovation project. It was sub-contracted out. The roof is complicated due to an addition that was put on the back of the house. The old roof had two layers - asphalt shingles over top of cedar shingles - no sheathing under the original cedar shingles. While in the attic I noticed that it appears they did not bring the sheathing up to the edge of a sidewall, but left the original shingles. (sorry if the wrong vocabulary is used, I am a novice) I can only add one picture since I’m new to the forum.
Any opinions would be appreciated. Many thanks!
