How to Attach Copper Flashing to Bricks

Copper flashing is very durable and helps ensure the roof overhang remains waterproof. Properly installing the copper flashing to the brick chimney or other brick structure on the roof ensures the water does not enter the brick wall. Many people wrongly open holes and try to screw the flashing to the brick, causing water to leak through the screw holes. With the right supplies and directions you will be able to install the copper flashing properly with no risk of water leak.
