What Kind Of Damage Can Hail Do To Roofs?

In Central Texas, hailstorms are a seasonal threat that can strike without warning, leaving a trail of property damage in their wake. For homeowners and business owners, one of the most vulnerable parts of any structure during a hailstorm is the roof. At Castex Roofing, we’ve seen firsthand how hail, no matter the size, can compromise roof integrity, shorten lifespan, and lead to costly repairs if not addressed promptly. Understanding the types of hail damage that can occur is the first step in protecting your property and ensuring timely maintenance.

Shingle Damage

One of the most common effects of hail is visible damage to asphalt shingles. Hailstones can cause dents, bruising, cracks, and granule loss. Even if a roof appears intact from the ground, granule loss can reduce UV protection and lead to premature aging of the shingle. Bruising beneath the surface may not be immediately visible but can compromise the waterproof barrier, increasing the risk of leaks over time.

Larger hailstones can completely crack or shatter shingles, especially if the roof is older or already weakened. This type of damage often requires shingle replacement or even a full roof replacement if the impact is widespread.

Metal Roof Denting

While metal roofs are highly durable, they’re not immune to hail damage. Large or high-velocity hailstones can leave noticeable dents and dings in panels, flashing, and ridge caps. While cosmetic damage may not immediately affect performance, deep dents can distort seams or damage protective coatings, potentially leading to rust or water intrusion.

At Castex Roofing, we inspect metal roofing for both structural and aesthetic damage after a hailstorm to ensure long-term performance.

Tile and Slate Cracking

Clay, concrete, and slate tiles are prone to cracking or breaking when hit by hail. These materials are strong but brittle, and a direct hit from even moderate-sized hail can leave cracks that allow water to seep beneath the tiles. If not addressed, this can result in leaks and damage to the underlayment or decking below.

We recommend prompt inspection after any storm for tile or slate roofing, as small cracks can worsen with time and exposure to heat and moisture.

Hidden Damage and Future Leaks

Not all hail damage is visible from the ground. Subtle issues like lifted shingles, punctured underlayment, or dented vents can lead to long-term problems if left unchecked. Over time, even minor hail damage can cause roof systems to fail, resulting in interior water damage, mold growth, and increased energy costs.
