The Importance of Addressing Chimney Leaks
As we’ve stated many times before, water is a chimney’s worst enemy. When water or moisture gets into your chimney, it can cause a wide range of serious problems. Water will bring even the most well-built chimney to its knees, causing cracked mortar, flaking bricks and compromising its structural integrity. When water gets into the creosote inside your chimney liner, it eats into the mortar, accelerating the damage.
There are many possible causes for a chimney leak, including:
Damaged/Defective Chimney Crowns
Missing/Defective Chimney Caps
Cracks/Gaps in the Mortar Joints or Chimney Masonry
Because it sticks up above the roof, your chimney is constantly exposed to the elements — wind, snow, rain and the freezing and thawing cycles of winter. Masonry materials are very porous, so they absorb a large amount of water. The constant cycle of freezing and thawing puts a large amount of stress on the chimney, leading to cracking, chimney leaks and structural damage.
Protect Yourself Against Chimney Leaks
There are several ways to protect yourself against chimney leaks:
- Make sure you have a professional-grade chimney cap installed.
- Replace or repair a damaged chimney crown.
- Repair chimney mortar cracks or gaps.
- Inspect and repair any leaky flashing around your chimney.
- Waterproof your chimney!
