Why Is My Chimney Leaking?

Chimneys are exposed to a variety of weather conditions all year round. One of the most common household problems is a leaking chimney, especially during rainy seasons. This can happen for different reasons, but the good news is that it can be easily fixed.

This article will cover all the possible reasons chimneys can have leaking problems and how to solve them.

How to recognize a chimney is leaking

The sooner you realize you’re dealing with a leaking chimney, the better. Unfortunately, many homeowners don’t realize that their chimney is leaking until it has already caused damage. The most obvious sign of a leaking chimney is water gathering in the fireplace or flue.

However, lots of other minor occurrences can also indicate that a chimney has a leak. For example, if you can hear water dripping somewhere in the vicinity of the chimney or if the house has an odd dank smell. Another sign of a leaky chimney is stains on the walls around the chimney, even cracked walls inside or outside the house.

Causes of chimney leaks

The most common cause is a missing or damaged part. The outer side of a chimney consists of four main parts: the chimney cap, chimney flashing, masonry, and chimney crown.

Chimney cap

If a chimney doesn’t have a cap, it’s natural that water seeps directly into it when it rains. The majority of chimneys come with chimney caps, which are also used to prevent debris and animals from getting in. If the chimney cap wasn’t properly installed, this could be the reason your chimney is leaking.

Chimney flashing

The flashing is an essential part of the chimney, as it separates the chimney and the roof. Its job is to keep water away from the chimney. Since it’s usually made from aluminum, it may rust or corrode, leading to a leak. It’s best to hire a professional to fix or install the chimney flashing, as it can be difficult and somewhat dangerous for those who don’t know what they’re doing.

Masonry

Heavy and consistent rain can also damage the masonry on the chimney, causing the bricks to crack and flake. Some homeowners solve this problem by waterproofing their chimneys, as it’s an effective way of keeping their chimneys in optimal conditions. This is usually done by professionals who apply a heavy coat of water repellent to the masonry.

Chimney crown

A chimney’s crown is the upper part made from cement used to keep the rain out of the chimney. Since it’s exposed to different weather conditions all the time, water and snow may create small cracks all over the crown. These small cracks may seem harmless at first, but they can quickly cause damage if left unchecked.

Prevent the chimney from leaking

It’s important to catch a leaking chimney early on. Whatever is causing your chimney to leak, the best solution is to call a professional who will determine the exact source of the problem and fix it before more damage is done.
