What Kind of Hail Will Damage an Asphalt Shingle Roof?

The roof is an essential component of any building. Besides protecting from harsh weather conditions, your roof keeps the structure safe and secure. However, when severe weather strikes, your roof can receive significant damage, and hail is one of the most damaging elements. Additionally, asphalt shingle roofing is particularly vulnerable to hail damage. The shingles can be easily cracked or even torn off, leaving the underlying structure exposed. In this blog, we will explore the different types of hail damage that can occur on an asphalt shingle roof. So, what kind of hail will damage an asphalt shingle roof? Let’s dive in.

First, What Kind of Hail Will Damage an Asphalt Shingle Roof?

Let’s get the short answer out of the way right away. Hail that’s a half-inch in diameter may be reason to call a professional roofer for an inspection – especially if strong wind is involved. However, if the hail is closer to an inch in diameter, count on damage and plan for repair work.

Damage that Hail Does to an Asphalt Shingle Roof

1. Bruising

Hail can cause dents or bruises on an asphalt shingle roof, leading to a loss of granules from the shingle surface. This can result in weakened shingles, which are more susceptible to damage from further hailstorms or other extreme weather conditions.

2. Cracking

Hail can also cause cracks in asphalt shingles, leading to leaks and other water damage. Even small cracks can allow water to penetrate the shingle. This can lead to damage to the underlying structure of the roof.

3. Puncturing

Larger hailstones can puncture through the surface of asphalt shingles, leaving holes that allow water to seep into the roof. This can result in significant damage to the underlying structure of the roof, as well as damage to the interior of the building.

4. Granule Loss

Asphalt shingles are coated with small granules that protect the shingle from UV rays and other environmental factors. Hail can dislodge granules from the shingle surface. As a result, this can weaken the shingle and leave it vulnerable to further damage.

5. Shingle Displacement

Hail can also cause asphalt shingles to become displaced from the roof, exposing the underlying structure to the elements. This can result in water damage to the roof and interior of the building, as well as potentially compromising the roof’s structural integrity.


In conclusion, hail can cause significant damage to asphalt shingle roofs, including bruising, cracking, puncturing, granule loss, and shingle displacement. If you suspect that your roof has been damaged by hail, it is important to have it inspected by a professional as soon as possible. Timely repairs can help prevent further damage and extend the life of your roof. Therefore, homeowners must invest in high-quality roofing materials that withstand severe weather conditions, including hail. By taking proactive steps to protect your roof, you can help ensure the safety and security of your home or business, even in the face of extreme weather.
