If water is entering the home through the ceiling near a chimney, one of the prime suspects is often the chimney flashing. Flashing is the sheet metal that keeps the intersection between the chimney and roof watertight. It comes in different types, depending on the design of the chimney and homeowner preference, but it is generally made of two layers of overlapping metal plates.
These plates form a double-layered “skirt” around the base of the chimney so there is no joint there where water can leak in. One layer sticks up from the roof, and the other layer hangs down from the chimney, draping over the first layer. In this way, the chimney can expand and contract with heat from a fire without damaging the flashing or the roof. The outer layer of flashing is called the counter flashing. The lower, inner layer of flashing is called the base flashing.
The top of the counter flashing is sunk into the mortar joint between two bricks in the chimney and then bent downward at a 90 degree angle. This joint is then usually sealed with caulk. The joints between the separate plates are also caulked.
Affordable Roofing installs copper flashing. 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.
