3 Reasons A Chimney Might Leak

Having fireplaces in the home serves as an asset when you want an additional heating source. Chimneys play a critical role in venting the smoke produced by a burning fire safely out of your home. While chimneys play an important role, then can also serve as a source of stress when they start to leak.

If you have noticed water coming into your home through its chimneys, here are three potential places you might want to look in order to identify the source of the leak.

1. Check the condition of the chimney cap.

Your chimney is fitted with a cap that protects the interior from penetration by small animals or moisture. When the cap is missing or damaged, water can easily infiltrate the chimney's liner and create a serious leak.

Replacing a missing or damaged chimney cap is an affordable way to address water leaks, so you should always start your investigation into a chimney leak by examining the condition of the chimney cap.

2. Check the condition of the chimney liner.

As you use your fireplace over time, the liner inside of the chimney can begin to corrode. This corrosion occurs when condensation from the gas fumes in the smoke of your fires accumulates on the interior surface of the liner.

The moisture from the condensation causes the liner material to corrode, leaving holes through which moisture from the outside can infiltrate your chimney. Checking the liner for signs of corrosion can help you determine if a faulty liner is to blame for your chimney leak.

3. Check the condition of the metal flashing around your chimney.

Strips of metal are applied to the seams where your chimney meets your home's roofing materials. This metal flashing is designed to help water flow away from the base of the chimney and safely into your roof's rain gutter system for removal.

Metal flashing can become damaged by high winds or heavy snowfall, rendering it vulnerable to water penetration. Conduct a visual inspection of your metal flashing for signs of damage or lifting when you notice a chimney leak, since replacing the flashing could be what is required to create a watertight seal around your chimney and prevent leaks in the future.

Being able to troubleshoot a chimney leak will help you identify the source of the moisture penetrating your home through its chimney. Carefully evaluate the condition of the chimney cap, liner, and the metal flashing around the chimney's base to identify potential problems, make the necessary repairs, and eliminate water leaks. Contact a contractor, like G.H. Erickson & Son, for more help.

About Me
Working With Professional Contractors

I have never been much of a DIY-er, but when I moved into my first home, I decided to try my hand at a few projects. My ideas blew up in my face--badly. I found myself struggling to put wiring back together and to repair the lawn that I had butchered. Instead of trying to clean up the mess and make things right on my own, I contacted a team of professional contractors for help. They were amazing to work with. They went through and worked room by room to repair my mistakes, and it was really incredible to see the difference they made.
