Chimney Leaks: Flashing
At Toledo Roofing Company, we are all out to ensure that no leaks occur in your home and your chimney is no exception to that. Having a fireplace in your home keeps it warm and cozy but that comfort is accompanied by a huge price – maintaining the chimney flashing.
But before we get ahead of ourselves and smoke out the problems associated with the chimney flashing, what exactly is a chimney flashing?
Chimney Flashing: All You Need to Know
Every chimney has a metal sheet that keeps the intersection between the metal sheet and the roof watertight. This metal sheet is called the chimney flash.
When done correctly, the flashing around s chimney consists of two layers:
The step or base flashing is installed underneath a shingle and bent upward against the brick chimney.
This section of the flashing consists of L-shaped sheet that are then woven into shingle courses and lapped all around the side of the chimney.
In counter flashing, a second layer of metal is embedded in the chimney mortar joints. This later of metal is then folded down to cover the top of the initial step flashing. The folded corners are especially vulnerable. When done, this cutting and bending leaves a small spot open that should be sealed or closed with a high-quality material like urethane caulk.
Caulk can come loose overtime however and sometimes, if the chimney flashing still loon as good as new, re-caulking can be an option rather than entire chimney overhaul. Take note though that caulk should not be a substitute for poorly overlapped flashing work.
Also, the metals used for flashing may last only for sometime and the type used will depend on your location. Most people prefer copper because it has a long half-life and can be soldered. Copper is also the best material for flashing because it’s durable and the corners form a more watertight connection.
How to check for leaks around chimney
It is quite difficult to detect leaks around your chimney right away but prolonged leaks can cause serious damage. The moisture from continuous leaks can deep into roofing, attic and even ceiling area if care is not taken. This can lead to further problems like wood for, roof damage, moss and algae growth and drywall damage in the ceilings. At Toledo Roofing Company, we recommend that you check your chimney flashing at least twice a year and be sure there are no signs of leakage or loose caulk. Be careful if you suspect leakage as there might already be wood rot.
