A Leaky Chimney Crown May Be Causing Your Chimney Leak!
Whenever it rains, snows, or sleets, your chimney crown takes a beating. Moisture (especially in excessive amounts) can have devastating effects on the chimney itself because of its erosive nature. Age and settling can also cause the chimney crown to crack, flake, and crumble — and unfortunately, once one little crack or hole is made, water will continuously wear away at it, making it bigger and bigger.
There are other problems that can cause crowns to leak as well — most commonly, improper construction. There are a few basic rules for building a long-lasting chimney crown:
- Chimney crowns should be built with a drip edge, which is an edge that extends beyond the chimney stack or chase by at least 2 inches.
- Chimney crowns should be built at least 3 inches thick at their thinnest point.
- Chimney crowns should be slightly sloped on all sides to encourage rain, snow, sleet, and ice to slip off instead of settling on top.
- Chimney crowns should be made of a strong, erosion-resistant cement, not a standard mortar.
Unfortunately, these basic rules aren’t always heeded during crown construction.
That’s why the crown is one of the first areas we inspect when we’re called out to locate a leak and repair a leaky chimney. If an inspection and leak investigation does reveal that the crown has damaged areas or that it wasn’t built properly at the start, the good news is: Trinity Chimney Service can help.
