How to Spot Hail Damage on Your Roof: A Homeowner's Guide

After a hailstorm, your roof may look fine from the ground — but hidden damage could be shortening its lifespan and leading to costly leaks. Here's what every homeowner should know about spotting hail damage early.

Signs of Hail Damage on Asphalt Shingles

The most common signs include dark spots where granules have been knocked off, cracked or broken shingles, dents in the shingle surface, and exposed fiberglass mat. Granule loss is particularly important — those granules protect the asphalt from UV damage, and without them, your shingles will deteriorate much faster.

Check Your Gutters and Downspouts

After a storm, look in your gutters for an unusual amount of granules. Some granule loss is normal over time, but a large accumulation after a storm is a red flag. Also check for dents in aluminum gutters — if hail dented your gutters, it likely damaged your shingles too.

Inspect Soft Metals Around Your Roof

Check your roof vents, flashing, and chimney caps for dents. These soft metals dent more easily than shingles, so they serve as a reliable indicator of hail impact on your roof.

What Size Hail Causes Damage?

Hail as small as 1 inch in diameter (about the size of a quarter) can damage asphalt shingles. Larger hailstones cause progressively more severe damage, with baseball-sized hail (2.75 inches) capable of punching holes through roofing materials.

When to Call a Professional

If you notice any of these signs — or if your area experienced a significant hailstorm — schedule a professional inspection right away. Many types of hail damage are difficult to see from the ground and worsen over time. A professional inspector can identify hidden damage and help you file an insurance claim before it's too late.

Most reputable roofing companies offer free storm damage inspections. Take advantage of this — the inspection costs nothing and could save you thousands in future repairs.
