Dangers of Leaking Chimney Flashing

by | Apr 12, 2017 | Chimney Leaks

Flashing is a vital component of the chimney system with a very specific job. Many other parts of the chimney system have dual purposes and multiple jobs. However, the flashing’s sole purpose is to protect the joints where the chimney meets the roof. If installed incorrectly, it allows water into the roof, the masonry, and the interior structure of the house.

Flashing is nothing but multiple sheets of thin metal placed in a specific pattern to protect the junction of roof and chimney. Many factors go into the flashing installation. This includes the type of roof (tin, shingles, metal, etc.), the slant of the roof, and the size and kind of chimney. This tedious process of flashing installation is essential for home safety and the life of your roof and chimney. A common reason that flashing leaks is improper installation, incorrect materials, or animal tampering. Only a certified chimney sweep should be trusted for this important work. He will know how to repair old flashing or install new flashing that will last.

What to Do if Your Chimney Leaks?

If you notice a chimney leak, you should schedule an inspection as soon as possible. Even if you experience a leak in another part of the house, you should have your chimney assessed. This is because water can travel through the interior structure until it reaches the lowest point, then will form a leak. One of the first things your chimney sweep will check is the flashing, as it’s a common source of leaks. An unaddressed leak can lead to structural damage, mold, and health-related risks.

Calling a chimney sweep is the best way to get to the bottom of a flashing leak. Calling a roofer or general contractor will cost time and money, but may not solve the problem. In fact, a roofer doesn’t even have the training and experience to install chimney flashing, though they might advertise that they do.

What’s the Big Deal?

If flashing is damaged, installed incorrectly, or missing, it allows water into the home to damage the structure and the chimney. Chimney leaks can stain, deteriorate, and damage beams, ceilings, floors, and wall coverings. Additionally, masonry chimneys are only waterproofed with special industry sealant above the roof. This means if water is allowed to trickle down the chimney it can cause damage to the masonry itself as well as unsightly stains. Water can wreak havoc on your masonry chimney and the chimney flashing is one of the best ways to prevent a chimney leak.
