Oh, Summer! Warmer weather, longer days, and…mild to severe thunderstorms. Believe it or not, these Summer storms can actually damage the exterior of your home, including your chimney, just as much as harsh winter weather! These storms bring rain, high winds, lightning, debris, and sometimes even hail with them. So what chimney damage should you watch out for this Summer?

Damage to the Chimney Crown and Cap

The chimney crown is the concrete slab that seals the top of your chimney; protecting it from moisture, debris, and animal entry into the chimney and flue. Unfortunately, if the crown was improperly constructed or has been previously damaged, it is more susceptible to leaks and damage during severe weather. Your chimney cap can become loosened – or even blow away entirely – due to winds during summer storms. The heavy rainfall can also cause areas of your chimney cap to rust.

Damage to the Flashing and Masonry

High winds and flying debris can cause the flashing to lose its watertight seal. Leading to moisture entering your chimney and possibly your home. Unfortunately since we live in an area with severe Winters, the masonry of your chimney can lead to decay and deterioration. Bricks act as a sponge, so the rainfall absorbed during the summer expands during the freeze-thaw cycle of the winter.

How To Prevent Summer Chimney Damage

The best way to prevent damage to your chimney during the summer – and throughout the rest of the year – is with regular maintenance. An annual chimney sweep keeps the flue clean and free from blockages while a regular chimney inspection ensures all chimney components are in good condition and have not been damaged. You should also sealcoat your chimney to deflect water absorption.
