Chimney Leaking? Here’s Why!

chimney-masonry-worn-brickOof! We know just how troubling a leaky chimney can be! Water damage of that sort can be costly to repair and it can certainly put a damper on your budget! And, more importantly, any excess water entering your home can create a health risk for you and your family. Therefore, it really is important to know why chimney leaks happen in the first place!

There are several reasons why chimneys begin to leak, and being aware of these causes can help you avoid the problem altogether. So, we have listed just some of these reasons for you below! All you’ve got to do is keep reading (and, of course, remember to contact our team when you need chimney repair in St. Paul, MN.)

Here’s What’s Going On

Like we mentioned above, there are a number of reasons why chimneys begin to leak. These include:


Chimneys develop condensation when water vapor is created as a byproduct of the combustion process. Without a chimney liner, this condensation can build on the walls of the chimney and leak into your home. Not only does this damage the home, but it’s also extremely dangerous.

Damage to the Brick and Mortar

The original brick and mortar material can develop leaks over time. Some people find cracks in the original chimney to be charming or to add character, but this is a major problem when it comes to potential moisture damage and creosote buildup. To prevent this, you can invest in waterproofing your chimney.

Leaky Chimney Flashing

The chimney flashing is what seals the chimney to the rooftop. The chimney flashing is angled to stop water from dripping into the home, but it can wear out over time. Eventually, chimney flashing needs replacement, and it can be a complicated job. Water-stained ceilings, mold and mildew, and other signs of water leakage often indicate the flashing is in need of repair or replacement.

No Top

Finally, an easy reason for moisture coming into the chimney is that there’s nothing stopping it from pouring right in as it rains. An open chimney top may have been the norm a century ago, but that doesn’t mean it’s safe.  A chimney cap can help you avoid this problem — it blocks the rain, which reduces moisture damage, and it keeps animals and small debris out. This is important because when debris gets stuck at the bottom of the chimney, it may allow carbon monoxide to leak into the home.
