Common Causes of Chimney Leaks

With the spring season upon us, we’re all ready for spring cleaning, spring showers, and some mucky weather. As we may start to rely less on our chimneys to keep us warm, there is still upkeep and work to be done to prepare for the off season. With increased rain and thawing ice, chimney leaks could be a concern and problem for some homeowners. Many leaks are minor and easy to fix, while some require more serious repairs and attention. Let’s take a look at some causes for these leaks.

4 Reasons Your Chimney Might Be Leaking

Mortar and/or Masonry Breaking Down

Luckily, the mortar that is on a chimney has a very long life, sometimes as long as 100 years. This expectancy is dependent on upkeep and protection from moisture, such as waterproofing efforts. Even a chimney that is taken care of well, however, can have issues with water. The most common reason for this is due to freeze and thaw cycles. In the colder months, if water finds its way into hairline fractures, it can freeze causing the gap to expand. When the ice thaws, you’ll be left with a larger crack than before. As this process repeats, it provides easier access for water to find its way inside your chimney and home.

Damaged Chimney Crown

At the top of your chimney, there is a cement surface called a chimney crown. This part of your chimney plays a vital role in keeping moisture out – especially in between the flue liner. Over time, this cement could be susceptible to cracks and damage that allows water to find its way inside. If small cracks are found early, spot fixes should solve the issue. However, if the cracks are expansive, a complete rebuild of that section may be necessary.

Missing Chimney Cap

Even on top of the chimney crown you need to have a chimney cap, which provides further protection from the elements. Rain, snow, debris, and critters are detracted due to this piece. If your chimney cap isn’t completely blocking debris from entering, it can allow debris to enter the chimney and block the path to allow fumes out. This can be dangerous as it can keep carbon monoxide inside. It is also a common cause for leaks.

Top Pan Issues on Chimney Chase

The top pan in chimneys lack durability. Occasionally, with a big rain storm, water can pool up. While this is an intended function of the top pan, sometimes as it sits it can cause rust. Over time, this can cause the pan to become brittle and crack allowing for leaks. Luckily this is a cheap and easy fix for your chimney professionals.
