Copper chimney flashing is the most durable type of flashing, with the longest service life. Properly maintained and serviced, it can last the life of your roof. It also has the advantage of being solderable, for a watertight seal. Copper can also be embedded in fresh mortar and won’t degrade, even in mortar that’s continuously saturated. Our flashing is custom made for your chimney out of 16 oz. sheet copper.

The top of the counter flashing is sunk into the mortar joint between the bricks in the chimney and then bent downward at a 90 degree angle. This joint is then sealed with caulk. The joints between the separate plates are also caulked.
