A leaking chimney can cause costly destruction such as ceiling stains, insulation saturation, drywall warping, mold growth, and structural damage. If you have a leaky chimney or you suspect chimney damage, it’s time for you to schedule a chimney leak repair.
Below are a few possible reasons why your chimney may be leaking:
Uncovered Chimney Tops: It’s normal for quite a bit of rain to fall straight down through the opining in your chimney if you do not have a chimney cap. A chimney cap not only keeps the water out, but it also prevents birds and debris from getting in, keeping the flue of your chimney unblocked. If the flue is blocked by anything, the blockage could lead to the release of carbon monoxide into your house and subsequently, the risk of carbon monoxide poisoning. If you don’t already have a chimney cap, now is a good time to buy one. At Bob Davis Chimney & Fireplace, we have our own fabrication facility where we construct both standard and custom-designed chimney caps with a lifetime warranty.
Cracks in the Chimney Crown: The cement part on the top of the chimney is called the crown. Its primary function is to keep rain and snow from falling in around the tiles. Over time, the chimney crown could be weakened as a result of water damage or the structure could shrink due to climate changes. Such cracks should be fixed promptly to stop the water from reaching further into your home and threatening the structure of your house.
Cracks in Bricks and Mortar Joints: From the day they are built, chimneys are exposed to harsh elements and temperature changes. Because the masonry structure is composed of very porous bricks and mortar joints, moisture and rainwater can easily soak into them. This causes cracks over time and allows water to fall down inside of the chimney and into the house.
Cracked or Torn Chimney Flashing: Flashing is a type of metal—usually aluminum—placed around the chimney base and covered with shingles to keep water from falling into the area where the chimney comes through the roofline. If the flashing is not properly installed or has worn away over time, water will find its way between the chimney and the roofline, causing leakage issues. Usually, some waterproof materials, such as tar and sealing products, are used to seal the flashing to prevent further leaks.
