The inspection
What we found. Holes in the chimney flashing and no proper counter flashing, multiple exposed nails, missing and lifting flashing on the lower roof, and wall-to-roof transitions in poor condition. In one area the substrate sloped toward the house.
The lower roof. The lower roof is low-slope, where shingles need two layers of underlayment. That was not there, and the shingles were at or past the end of their service life.
Our recommendations. Replace the lower roof with proper low-slope detailing and underlayment, tune up and reseal the upper roof, and fully replace the chimney flashing with step and counter flashing.
