Chimney leak from failed flashing or crown
Why it happens here
Wind-driven rain on the ridge above Clinton Parkway pushes water past flashing that has worked loose, and freeze-thaw cycles crack the crown at the flue bond. Both let water into the attic and down the stack.
Our approach
We rebuild flashing with a flashing bender for a tight fit, pour a new crown with chimney crown mix, and seal both with waterproofing sealant. Then we hose-test the repair before we pack up.
