5 Biggest Signs of a Chimney Leak

When a chimney first starts leaking, you might not realize it right away. It’ll take some time for you to notice that your chimney leaks when it rains since most leaks will start off small.

But over time, you will begin to see signs of a chimney leak. You might also recognize that you could have a leak simply by inspecting your chimney from time to time. Here are five of the biggest signs of a chimney leak.

1. No Cover on the Top of Your Chimney

The cover that sits on the top of your chimney is designed to keep everything from animals to debris out of it. It’s also in place to prevent rain from falling directly down your chimney.

As a result, you’re often going to find that rainwater will be able to get into your chimney and make its way into your home if you don’t have a chimney cover. You will need to have a missing chimney cover replaced ASAP to stop this from turning into a big problem.

2. Damaged Crown on Your Chimney

A chimney crown is located right underneath a chimney cover. One of its sole purposes is to stop rain from being able to enter your chimney.

But as your chimney expands and contracts over the course of the year with the different weather patterns, your chimney crown can crack. And even a small crack in your chimney crown can invite rainwater to come into your home.

You should sneak a peek at your chimney crown every so often and look for any signs of cracking. You will need to get a damaged chimney crown either repaired or replaced to avoid letting moisture enter your home through it.

3. Worn-Out Brick and Mortar Joints in Your Chimney

When your chimney was first built, the bricks and mortar that were used to create it were very strong. But over time, the joints in between the bricks and mortar can start to weaken and let water pass through them.

If this is happening in your home, you will no doubt have at least some rainwater sneaking through the cracks in between brick-and-mortar joints. You’ll need to have these cracks repaired and consider waterproofing your chimney sometime soon.

4. Faulty Flashing Around Your Chimney

All of the various things in your home that come up through your roof need to have what’s called flashing around them. Flashing is a thin piece of metal that is put into place to stop rainwater from getting into a home through the cracks that surround chimneys, vents, etc.

Flashing can wear down over the years and eventually stop doing its job. It can also get damaged if you ever have a new roof installed and roofers don’t take the time to replace it.

You should inspect the flashing for your chimney and replace it if you see that it’s no longer providing your chimney with the protection it needs.

5. Condensation Inside Your Chimney

Most chimneys have liners in them that prevent the interior of the chimney from overheating. These liners are also designed to stop condensation from building up in a chimney.

If you have a chimney liner that has gone bad or, worse, if you don’t have a liner at all, you should look into getting one. Otherwise, this could be to blame for your leaky chimney.

How Chimney Leaks Can Affect Your Home

If you fail to recognize the signs of a chimney leak or simply choose to ignore them, it isn’t going to bode well for your home. Chimney leaks can cause a wide range of complications in a house.

A chimney leak can result in:

  • Damage done to the walls in your home that surround your chimney
  • Any wood around the perimeter of your chimney rotting
  • Mold growing in the areas around your chimney

If you experience any of these issues, it will put you in a position where you’ll have to repair both your chimney and whatever other problems a chimney leak caused. It’s why you shouldn’t hesitate to get help with a chimney leak as soon as you notice it.
