Is your chimney leaking? There are several things that could be causing this, such as structural damage to your chimney or a broken chimney cap. Probably the most common problem that causes chimney leaks is broken, worn out, or incorrectly installed flashing.
What is Flashing?
The flashing is simply metal strips that cover the connection where the chimney meets the roof. It many times is made up of two layers – the step flashing and the counter flashing. Step flashing is L-shaped metal pieces that are “woven into the shingle courses and lapped up the side of the chimney.” Counter flashing then covers the edges of the step flashing, which helps to double protect against leaks.
Flashing can actually be made of materials other than sheet metal, such as plastic or composite materials, but the best bet is to stick with sheet metal, even if it is more expensive. Sheet metal is an effective defense against the leaks that you’re trying to avoid in your chimney.
Make Sure It Can Move
One important thing to remember is that there is a difference in the very solid structure of your chimney and the more flexible movement of your roof deck. This is another reason that the two-part flashing system is a good thing. This allows for movement while maintaining a seal that will protect your roof from water.
Signs That Your Roof is Leaking
There are signs to look for if you suspect that your roof might be leaking. Take a look at the mortar and bricks of your chimney. If they are flaking and peeling, it may be that you have a leak. Also, take a look around your fireplace. If the woodwork looks warped or the paint is bubbling, or if the wallpaper is torn or weakened, it could very well be that you need someone like the experts at Jiminy Chimney Masonry and Repair to take a closer look at what kind of shape your flashing is in. Sometimes it can have pin-point holes in it, simply from corrosion. Strong winds or rain can cause your flashing to loosen up. Sometimes flashing could just be improperly installed. Any of these things can cause leaks, and all of them can be fixed by the crew at Jiminy Chimney.
