How Hail Can Damage Your Roof and What to Do About It

Hailstorms can wreak havoc on your home, and your roof takes the hardest hit. Even small hailstones can cause significant damage, leading to costly repairs or even the need for a full replacement. Understanding how hail affects your roof and what steps to take afterward can help protect your home and your investment.

How Hail Damages Your Roof

1. Shingle Bruising and Granule Loss

When hailstones strike asphalt shingles, they dislodge granules from the surface. These granules protect the shingles from UV rays and water penetration, so losing them can shorten your roof’s lifespan. In some cases, the impact causes bruising, making the shingles more vulnerable to leaks over time.

2. Cracks and Fractures in Shingles

Larger hailstones can cause cracks or splits in asphalt, wood, or tile shingles. These fractures expose your roof to moisture, leading to water leaks, mold growth, and structural damage. Over time, cracked shingles will weaken and allow more water to seep in.

3. Damage to Flashing and Gutters

Hail can dent metal flashing, loosen gutters, or even break down their protective coatings. When flashing and gutters are compromised, water may not drain properly, leading to foundation issues and water pooling on your roof.

4. Indentations on Metal Roofs

While metal roofs are highly durable, large hailstones can still leave visible dents or dings. Though this might not immediately impact functionality, severe indentations could weaken the material over time.

5. Weakened Roof Sealant and Underlayment

If hail is large enough, it can break through the top layer of shingles and damage the underlayment. This weakens the overall integrity of your roof, making it more prone to leaks, especially during heavy rains.

Signs of Hail Damage to Watch For

After a hailstorm, check for the following: ✅ Missing or loose granules on shingles✅ Dents, cracks, or bruising on shingles✅ Damaged flashing or gutters✅ Leaks or water stains on ceilings and walls✅ Shingles that appear lifted or curling
