What to Watch for After Summer Storms

Just when you thought your chimney was out of the woods after a long, snowy winter, here comes summer. Here in Pittsburgh, we’re no strangers to summer storms. The hot, humid weather can lead to microbursts, which bring localized heavy rain, hail, and tropical storm winds that can damage masonry chimneys. So far this summer, the Pittsburgh area has received over five inches of rainfall, nearly double the amount from last year. To protect the structural integrity of your chimney, here’s what to watch after summer storms.

Summer Storms Can Damage Chimneys

Summer storms, particularly microbursts common in our region, can add significant pressure on your home, and your chimney often bears the brunt of it. High winds can dislodge components, heavy rain can penetrate already weakened areas, and hail can damage the crown. These storms can compromise the chimney’s structural integrity and its ability to vent smoke and exhaust.

Chimney Leaks

One of the most immediate concerns after a heavy storm is a chimney leak. It might appear as water stains on your ceiling or walls near the fireplace, a puddle inside the firebox, or even dripping sounds. Leaks are not always immediately evident and often go unnoticed until significant damage has occurred.

Water Damage

Heavy rainfall and localized flooding can cause extensive damage to the chimney and its interior components. This damage can weaken the flue liner, erode mortar joints, and even create conditions for mold and mildew to grow within the chimney structure and invade your home.

Chimney Crown Cracks

The crown protects the chimney flue and masonry from moisture intrusion. However, strong winds or hail can cause new cracks and widen existing ones, allowing water to seep directly into the chimney’s interior.

Dislodged Flue Cap

A secure flue cap prevents rain, debris, and animals from entering your chimney. But high winds during a storm can easily dislodge or damage this protective cover, leaving your flue vulnerable to water intrusion, pests, and blockages that can make your fireplace or stove unsafe to light.

Rusted Chimney Chase Cover

If you have a pre-fabricated chimney, it likely has a metal chase cover at the top. Hail and wind-driven rain can damage the protective coating on these covers, leading to rust. A rusted chase cover will eventually allow water to enter the chimney chase, damaging the flue and its components.

Warped Flashing

The chimney flashing is supposed to prevent water from entering the joint where the chimney meets the roofline. Strong winds and heavy rain can bend, tear, or dislodge the flashing, creating an open pathway for water to enter and damage the attic, roof deck, ceiling, and walls in your home.

What to Do After a Summer Storm

After a summer storm, it’s essential to conduct a visual inspection of your chimney from the ground when it is safe to do so. Look for any visible damage to the:

• Chimney cap
• Chimney crown
• Exterior bricks and mortar
• Flashing

If you notice or suspect any damage, it’s essential to act quickly. Ignoring storm damage can lead to more extensive and costly repairs, as well as potential safety hazards. Even if you don’t see immediate signs of chimney damage, a professional inspection is highly recommended, especially after a severe summer storm has passed through the area.
