This roof had been leaking off and on for some time. Adoon Smith went out there and diagnosed the problem as the flashing around a vent.
We came out and fixed this by first removing shingles from vent. Then we installed Ice and water shield. Next, we installed step flashing and flashing to vent. Then, we installed the surface mount counter flashing. Following that, we painted and sealed vent and counter flashing to match shingles. We finished up by re-shingling properly.
What a difference a repair makes!
