Chimney leaks when it rains is a common issue we see during the rainy season. Though chimneys may appear to be a solid block or marble column, they actually have several distinct parts. And since they’re always exposed to the elements, they’re more vulnerable to damage.
Sometimes the impact of a rough climate on a chimney isn’t obvious, but here are some things to watch out for.
Chimney flues are constructed of one or two foot sections of terracotta clay liner. Some chimneys are unlined without the safety benefit of a series of clay flue liners. Both of these substances are subject to water damage without appropriate treatment. Water can do a lot of harm once it gets into a house. These are some signs your flue might be cracked and leaking:
- Mold and rot
- Dripping roof
- Dank smells
- Warped floors
- Efflorescence on the firebox brick or fireplace facing material
- Peeling or paint or plaster on a wall next to the fireplace facade
The chimney is often one of the most overlooked parts of a home. It seems solid, but the interior is fairly delicate.
Cracks in the masonry are not uncommon, but unfortunately, they’re usually the most costly to repair. On the upside, you’re less likely to overlook the damage until it turns into a chimney leak.
Broken or Missing Cover
It seems so simple, yet we often see chimneys that have faulty covers, or no cover at all. Luckily, this is an easy issue to fix. A chimney cap with mesh netting keeps rain out of the chimney and attic, as well as animals.
Moisture damage can cause bricks to tumble down inside the chimney. This is mostly an issue with older homes that aren’t lined properly. Nests can also stop up a chimney. The resulting clog interferes with airflow, which is dangerous if carbon monoxide is able to build up.
