Chimney leaks from failed flashing
Why it happens here
The hilly terrain in Hillcrest pushes water against the uphill side of the chimney. The flashing is the first line of defense, and when it pulls away from the brick or rusts through, water goes straight in. This is the most common leak source we find.
Our approach
We remove the old flashing, install new copper or aluminum flashing, and seal it properly to both the chimney and the roof. Then we waterproof the brick so water cannot soak in from the sides. We also check the crown while we are up there.
