There’s truth in the saying “April showers bring May flowers,” but if you aren’t careful, those showers can also bring devastating leaks – especially when it comes to your chimney. The tips below will help you ensure that your roof and chimney are in the best possible condition.
By following these tips, you can avoid potential leaks and the associated costly repairs.
Use a Chimney Cap
The best way to prevent leaks is to install a chimney cap or repair the one already in place. The chimney cap is designed to prevent rainwater from traveling straight down through the chimney and into the fireplace area, making it one of the most important components of the system.
If you don’t have one, you should install one right away. Otherwise, a chimney cap check is included in your annual maintenance. You might also consider a top-sealing damper, which seals tight when closed thanks to a heavy-duty gasket.
Repair Your Masonry
Another common cause of chimney-related leaks is cracked masonry. The masonry is the only thing separating the inside of your chimney from the elements. If it cracks, water can easily penetrate and enter the space between your chimney and liner.
This can cause numerous issues, including mildew, black mold, or significant rot. Never put off chimney masonry repairs; doing so could cost you tens of thousands of dollars in repairs.
Check and Repair Flashing at the Base
Failed flashing is often the cause of some of the most devastating chimney leaks. Fortunately, it is relatively easy to repair your flashing, and installing new flashing is almost as simple if needed.
Flashing consists of metal strips that cover the tiny gap between your chimney and your roof. While it typically serves its purpose, it can become loose, crack, or split over time. One of the best ways to prevent this is by using a flashing sealant.
Tar is the most popular, but a few companies make elastomeric sealants that last far longer.
Consider Waterproofing the Brick and Chimney Crown
Though the benefits of waterproofing your chimney are still debated, it is beneficial for those in especially rainy and windy climates, such as Chicago. Waterproofing stops rain, snow, ice, and meltwater from penetrating into the porous brick and concrete structures of your chimney.
This helps negate the possibility of leaks and can also prevent cracked and discolored masonry. However, this is only effective if you purchase a quality product and hire a professional to apply it.
Though all these tips can significantly protect your home from damage associated with chimney leaks, the absolute best thing you can do is have your chimney cleaned and inspected at least once per year. Trained professionals can spot potential problems before they allow for leaks, saving you hundreds, thousands, or even tens of thousands of dollars.
