What Causes Fireplace Leaks?

The most common cause of fireplace leaks is wear and tear on the chimney. Others are leaks in the flashing, mortar, or chimney cap. The following are some of the causes of fireplace leaks:

Damaged Flashing

Flashing is a protective layer, usually made of aluminum or steel, that acts as a sealant between the base of your chimney and your roof when combined with tar. You run the risk of letting water into your fireplace if the flashing seal is damaged or comes loose in any way. The good news is that flashing damage can be detected early and then fixed by a professional.

Chimney Cap Damage

A chimney cap is a metal piece that fits on top of your chimney to keep animals and water out of your fireplace. Water can easily enter a chimney cap if any area of either the solid top or mesh siding develops big gaps. It may simply become worn out over time or damaged by severe storms or animal intrusion. This kind of damage is often difficult to detect.

Deterioration of the Mortar and Bricks

When the mortar that holds your fireplace bricks together begins to deteriorate, it does a poor job of keeping water out. It is possible that your mortar is nearing the end of its useful life if you see areas near your chimney that appear worn out or are unusually wet. This can be fixed, just like the causes of other fireplace leaks

Faulty House Siding

The siding of a house could impact the efficiency of a fireplace. If the wood siding on your home is warped, missing, or peeling away, water may seep through the siding and into your chimney. It is important you replace or repair your siding when it is faulty.

Completely Unconnected Damage

There are times when a leak originates elsewhere but is eventually able to get to the chimney, where it then visibly enters a room at the point of the chimney.
