Crumbling chimney crowns on wind-exposed roofs
Why it happens here
The crown takes the full force of wind-driven rain and the freeze-thaw cycle. Water gets into hairline cracks, freezes, and pries them open wider each winter. After a few seasons, the crown is cracked through.
Our approach
We rebuild the crown with a flexible crown mix that moves with the freeze-thaw cycle instead of cracking. We also add the correct overhang so water drips off instead of running down the brick.
