What Texas Hail and Windstorms Can Do to a Chimney Without You Noticing

By the Lowes Chimney Sweep crew · Plano, TX

North Texas gets some of the most punishing hail and windstorms in the country, and after one rolls through, you check the roof, the fence, maybe the car. But almost nobody checks the chimney — because you can't really see the top of it from the ground. That's exactly the problem. Your chimney sticks up higher than anything else on the roof, which makes it a prime target for hail and wind, and the damage it takes is often invisible from below while it quietly opens the door to leaks and deterioration. Here's what these storms do to a chimney up where you can't see, and why a look after a big one is worth it.

Your Chimney Takes the Storm's Full Force

Think about where your chimney sits: the highest, most exposed point on the house, with no trees or structures shielding it. Hail slams into it from above and wind hits it from every side. Unlike the broad, sloped roof that sheds a lot of the impact, the chimney's flat crown, metal cap, and vertical brick faces take direct hits. So while your shingles might survive a storm that your chimney doesn't, you'd never know, because all of that action happens above your sight line. The chimney frequently sustains the worst damage on the whole roof and gets checked the least.

What Hail and Wind Actually Damage

Here's what we find after North Texas storms, none of it visible from the yard:

The cap. Hail dents and crushes caps, and high winds tear off ones that were poorly fitted or corroded. A damaged or missing cap leaves the flue open to rain and animals — often fixed with a new chimney cap.

The crown. Hail impact cracks and chips the concrete crown, and once it's cracked, water pours in. This is one of the most common and most consequential storm hits — crown repair work.

The brick and mortar. Wind-driven hail chips brick faces and can loosen mortar joints, weakening the masonry and creating new paths for water — addressed with masonry repair.

The flashing and chase cover. Wind lifts and bends flashing, and hail dents metal chase covers, both of which then leak.

Why You Don't Notice — Until It Leaks

The insidious thing about storm damage to a chimney is the delay. A hail-cracked crown or a bent piece of flashing doesn't announce itself. Everything looks normal from inside the house — until weeks or months later, when a heavy rain finds the new crack and you get a water stain on the ceiling or that white efflorescence on the brick. By then the storm is a distant memory and you don't connect the leak to it. Meanwhile, every rain in between has been enlarging the damage. The gap between the storm and the symptom is exactly why chimneys get overlooked and why the damage compounds.

There May Be an Insurance Angle

Here's something worth knowing: storm damage to a chimney is often covered by homeowners insurance, since it's sudden damage from a specific event rather than gradual wear. If a hailstorm cracked your crown or blew off your cap, that may be a claimable repair. But claims are much easier when the damage is documented soon after the storm and clearly tied to it — which is another reason a prompt post-storm inspection pays off. A professional can photograph and document the damage in a way that supports a claim, potentially saving you the out-of-pocket cost entirely.

Why a Post-Storm Inspection Is Worth It

You can't assess chimney storm damage from the ground, and climbing up yourself is neither safe nor useful without knowing what to look for. A chimney inspection after a significant hail or windstorm checks the cap, crown, brick, flashing, and chase cover, catches the hidden damage while it's still small, and documents it with photos. Catching a cracked crown right after the storm — before months of rain have poured through it — is the difference between a modest repair and a major water-damage project. It's a small, smart step after the kind of weather North Texas hands us every year.
