Summer in Minnesota brings warm days, backyard fun, and unfortunately, powerful thunderstorms that can wreak havoc on your home’s chimney. To keep your fireplace and chimney system safe and functional, it’s essential to be proactive about protection. That’s why we always recommend scheduling a chimney inspection in Minneapolis, MN, before or during the rainy season to catch problems early.
At 2nd Generation Chimneys, we’ve seen how summer storms can quietly damage your chimney over time. Even if you don’t see visible cracks or leaks, water can infiltrate small openings, freeze and expand later, and eventually compromise your chimney’s structure. That leads to issues like weakened mortar joints, spalling bricks, rusted components, and interior water damage—all of which are preventable with the right care.
How Summer Storms Impact Chimneys
Heavy rains and high winds can do more than just dampen your evening plans. Rainwater can enter your chimney flue, seep into bricks and mortar, and begin breaking down your chimney from the inside out. Over time, this water damage can cause mold, odors, and even structural issues that affect your entire fireplace system.
Wind-driven rain is especially dangerous, as it often finds its way through flashing, chimney caps, or crown cracks. Once moisture gets inside, it doesn’t just dry out. It lingers, promoting decay and corrosion.
Excess moisture can also impact the efficiency of your fireplace or stove. If your chimney liner becomes damaged or compromised by water intrusion, it can reduce draft performance or lead to dangerous gas buildup inside your home. The result? Poor indoor air quality and potentially serious safety risks.
Waterproofing Is Key
One of the best things you can do to protect your chimney during storm season is to waterproof it. A professional chimney waterproofing treatment creates a breathable seal over your masonry, allowing moisture inside the bricks to escape while preventing new water from entering. It’s a smart, cost-effective step to extend the life of your chimney and avoid costly repairs down the road.
Don’t Forget the Chimney Cap
If you don’t already have a chimney cap, now’s the time to install one. A properly fitted chimney cap keeps rain, animals, and debris out of your flue while still allowing smoke and gases to escape. It’s one of the simplest but most essential tools for storm-proofing your chimney.
Already have a cap? Great—just make sure it’s in good condition. Summer storms can loosen or damage caps, which means even the best one won’t do its job if it’s not secure.
