You rely on your home's chimney to safely remove all traces of carbon dioxide and toxic gases from fireplaces and other interior sources that burn wood, oil, and coal. While these features are sturdy and built to withstand the elements, they can still sustain exterior damage from heavy rain and wind that requires chimney repairs. The following guide outlines several ways that stormy weather may affect a chimney's operation and structural integrity.

How Storms Can Damage Your Chimney

1. Crack Mortar and Brick

Frequent and heavy storms can cause cracks to emerge in the chimney's mortar. These weak spots may also lead to fissures in the bricks, which can eventually fall away from the chimney as they deteriorate. Depending on the weather's severity, homeowners may find piles of bricks on the roof or in the yard. Cracked mortar can also mask interior structural damage.

2. Tear and Warp Flashing

A chimney has flashing around the seams where the stack meets the roof. These pieces are often made from galvanized metal or rubber, and they cover and seal the spaces where moisture could seep through. Severe weather, like strong winds, can snap tree branches or toss around other debris that could impact the flashing. As a result, sheets could tear or warp and pull away from the chimney. 

Rain can get into these openings, and unaddressed leaks can cause water damage to the roof and underlying materials. Chimney repair specialists say leaks that drip into fireplaces are among the top signs of torn or damaged flashing.

3. Displace Chimney Caps

Storms are notorious for causing the chimney cap to blow off. This metal component is designed to keep rain, twigs, rodents, and other unwanted items from coming down the shaft. Winds and rain can completely remove the cap or cause it to shift. If this key part is not secured properly, your home is also susceptible to water leaks, which can lead to mold and mildew growth.

4. Cause Heavy Moisture Absorption

The chimney's masonry is also susceptible to moisture buildup after frequent storms. As a result, a condition known as efflorescence can develop. When this happens, clumps of chalky, white deposits may start to leach out of the bricks of the structure. Their presence is typically a sign that bricks and masonry are absorbing high levels of moisture. If not repaired promptly, efflorescence can lead to extensive structural damage to the home's exterior.
