How to Identify Hail Damage on a Roof

Colorado hail doesn't always leave an obvious calling card. A roof can look fine from the street while hail has bruised the shingles underneath — damage that quietly becomes a leak months later. Here's how to spot it, what to check safely from the ground, and when to bring in a professional.

What hail actually does to a roof

Hail damages roofs in two ways. The obvious kind — cracked shingles, punctures, shattered tile — shows up immediately. The sneaky kind is bruising: the hailstone compresses the shingle mat and knocks off the protective granule coating, leaving a soft dark spot. The roof doesn't leak today. But with the granules gone, Colorado's high-altitude sun bakes the exposed asphalt, and within a season or two, that bruise becomes a failure point.

This is why "my roof looks fine" after a hailstorm is the most expensive sentence in Colorado roofing.

The safe ground-level check

Grab binoculars and walk your property's perimeter. You're looking for:

• Dented gutters and downspouts. Metal shows hail clearly. If your gutters are dimpled, your shingles took hits too.
• Damaged siding, window screens, and AC fins. Collateral damage confirms the storm's severity at your address.
• Debris on the ground. Shingle pieces, granule piles at downspout exits, broken tree limbs.
• Visible shingle damage. From the ground with binoculars: missing pieces, lifted tabs, dark patches.

Also check inside: walk the attic during daylight and look for pinpricks of light through the decking, plus any damp spots on rafters or insulation.

Signs on asphalt shingles

Asphalt shingles — the most common Colorado roofing — show hail as:

• Bruises: dark, soft spots where granules were knocked away. A pro can feel the difference; from the ground, look for uneven dark patches.
• Granule loss: heavy granule piles in gutters or at downspout mouths after a storm. Some loss is normal aging; sudden heavy loss is hail's signature.
• Cracks and splits: large hailstones crack shingles outright — these leak with the next rain.
• Exposed fiberglass mat: shiny spots where the asphalt layer was blasted off entirely.

Signs on metal, tile, and flat roofs

• Metal: cosmetic denting on panels, vents, and flashing. Standing-seam systems usually keep performing despite dents — but check seams and fasteners.
• Tile (clay/concrete): cracked or shattered tiles. One broken tile is an open door for water — these need prompt replacement.
• Flat/low-slope: punctures in the membrane, damaged flashing at edges and penetrations, and clogged drains that turn ponding into leaks.

How to document what you find

If you suspect hail damage, document before you call anyone:

1. Photograph everything from the ground — dents, debris, granule piles — with dates.
2. Note the storm date. Colorado hail season runs roughly mid-April through mid-September.
3. Keep a simple written log: what you saw, where, when.
4. Don't disturb anything. Leave the roof untouched for the professional inspection.

Good documentation helps every conversation that follows — with a roofer, and with your insurer if you go that route.

When to call a roofer

Call for a professional inspection if you see any of the signs above, if neighbors are getting roof work after the same storm, or if your roof is over 10 years old in hail country — older shingles bruise more easily. A proper inspection covers the full roof surface, flashing, vents, and the attic underside.
