Leaking roof vent or flashing

Answer: call a roofer.

Leaks around roof vents, pipes, or flashing are one of the most common causes of roof leaks. Flashing — the thin metal strips that seal transitions between the roof and chimneys, vents, or walls — deteriorates over time from UV exposure, thermal cycling, and storms. Even a small gap lets water infiltrate into the attic and down through ceilings. A roofer can remove the old flashing, install new step or counter flashing, reseal vent boots, and verify there's no hidden water damage in the decking below.
