Factors That Could Cause Your Chimney To Leak

Many of us want to know that everything is in working order with our fireplaces and chimney systems as the winter months approach. Sometimes issues need to be resolved before one may enjoy a winter of toasty flames. Leaks in chimneys are a significant problem. It’s critical to address any minor issues with your chimney as soon as possible because they could lead to bigger issues later.

It’s stressful and frustrating whenever you have a leak. Chimney leaks are among the most irritating ones. The uncertainty of whether to contact a chimney company or a roofing company only serves to increase your frustration. The truth is that your chimney could be leaking for a variety of reasons, and who you call will depend on what kind of leak it is.

1. The fireplace flashing is cracked
The flashing is the material—typically aluminum—that covers the portion of the chimney that protrudes through your roof and curves over the chimney’s side and roofing shingles. Flashing prevents water from entering the space between the roof and the chimney. In order to stop flashing leaks, waterproof tar is typically used to seal the flashing. However, this tar ultimately wears away, leading to issues. Tar doesn’t last as long as specialty sealing products, but they perform the job correctly.

2. Leaking chimney from a rusty chase top
You’ll have a chase top over the top of your chimney to prevent rainwater from entering the chimney directly. It will have a caulk-sealed hole cut out in the center for the chimney pipe and spark arrester to pass through. The chase will contain water if it is lower in the center than the remainder of the steel panel. The chase top is corroded through, as a result, allowing water to enter the chimney.

3. In mortar joints and bricks, cracks appear
Bricks and mortar are porous enough to absorb water when it rains if you have a brick chimney. The chase top (the top of your chimney) should always direct water evenly in all directions. Both the bricks themselves and the mortar and cement holding the chimney together may crack with time. Water may then fall inside the chimney and the house as a result of this. Even worse, after a rain, chimney walls in shaded locations will remain wet for a longer period of time, and the bricks will absorb the water and eventually let it seep into the home.

3. Cracks and loose knots in wood siding
When your home has wooden siding, there are two scenarios that could impact the condition of your chimney. In one instance, the wood’s knots will either loosen or fall off completely. The wood on the other could deteriorate, dry up, and crack. Water can enter the chimney and the home through the siding in either situation. Having a professional come out and inspect that everything in the siding and chimney is sealed properly is the best course of action in this situation.

Numerous factors might cause a chimney leak, which is typically repairable. To prevent significant concerns, it’s critical to identify problems early and take appropriate action.
