Chimney flashing failure on brick chimneys
Why it happens here
Brick chimneys in Pine Hills have often settled slightly over 50 years, opening gaps where the flashing meets the masonry. Caulk patches fail within a season because the masonry moves with temperature changes. Water gets behind the flashing and into the attic.
Our approach
We remove the old flashing entirely and install new step and counter flashing cut into the mortar joints. Then we seal with polyurethane caulk rated for Florida heat. This is a permanent fix, not a patch, and it usually takes three to four hours.
