How to Tell if Hail Damaged Your Roof

Hail rarely announces itself the way a fallen tree limb or a missing shingle does. Most hail damage is subtle, sitting on the roof surface where it is difficult to see from the ground, yet it can still compromise how well your roof sheds water. Knowing what to check after a storm helps you decide whether it is time to call a professional.

Start With Evidence Around Your Property

Before you even think about the roof itself, walk your property for ground-level clues that a hail event was significant enough to cause damage.

Granules in the gutters: Check gutters and downspout splash blocks for accumulated asphalt granules dislodged from shingles during the storm.
Dented gutters and downspouts: Soft metal components dent easily and help establish the approximate size of the hail that hit your property.
Dented air conditioning units, vents, or siding: These exterior surfaces often show hail impact clearly, even when the roof damage above is harder to spot.
Damaged window screens or dented vehicles: If cars or screens on your property show hail marks, the roof was very likely hit with similar force.

Signs of Hail Damage by Roofing Material

Asphalt Shingles

Asphalt shingles are the most common roofing material in the United States and the most susceptible to visible hail impact. Look for:

Granule loss: Impacts dislodge the protective granule layer, exposing the asphalt mat underneath.
Soft bruising: Larger hailstones create circular impact marks that resemble a bruise — the fiberglass mat below is fractured even if the surface looks intact.
Cracking or splitting: Severe impacts crack shingles outright, letting water reach the underlayment immediately.
Broken seal strips: Hail can break the adhesive strips that bond shingles to each other, increasing wind-uplift risk in future storms.

Metal Roofing

Metal roofs are significantly more hail-resistant than asphalt shingles, but they are not immune. Look for cosmetic dents, damage to exposed fasteners on through-fastened panels, and cracked or chipped paint coatings that can lead to corrosion over time.

Tile Roofing

Concrete and clay tile are brittle and crack readily under hail impact — even hailstones under 1 inch in diameter can crack individual tiles. Broken tiles expose the underlayment and create an immediate leak pathway if not replaced promptly.

Wood Shakes and Shingles

Wood shakes show hail impact as sharp-edged splits that run with the wood grain. Unlike asphalt bruising, these splits are usually easy to spot on inspection, and splits that penetrate through the shake create an immediate water intrusion risk.

What a Professional Inspection Checks That You Can't See From the Ground

A roofing contractor performing a hail damage inspection examines more than just the visible shingle surface:

Ridge and hip caps: Often the most exposed surfaces and the first to show damage.
Metal components: Vents, pipe boots, flashing, and skylights, which dent visibly and help confirm hail size.
Attic interior: Daylight penetration, water staining, or compromised decking that would not be visible from the roof surface.

Inspectors typically photograph each impact point and produce a written report documenting hail size estimates based on the diameter of impact marks on soft metals like aluminum gutters. For more on what a professional roof inspection includes, see Inspections & Assessments.

When to Call a Professional

Because most hail damage is not visible from the ground, the safest approach after any hailstorm is a prompt professional inspection — even if you see no interior symptoms. Hail damage that goes unaddressed often worsens over 12 to 24 months as granule loss accelerates water intrusion into the asphalt mat. Acting quickly also matters for insurance: delayed filing gives insurers grounds to attribute damage to wear and tear rather than the storm.

Frequently Asked Questions

What does hail damage look like on asphalt shingles?

Hail impact on asphalt shingles typically shows up as soft, circular bruising where the fiberglass mat underneath is fractured even if the surface looks intact, along with granule loss that exposes the asphalt mat. Larger impacts can crack or split the shingle outright, and hail can also break the adhesive seal strips that bond shingles together.

Why do I need to check my gutters after a hailstorm?

Granules dislodged from asphalt shingles accumulate in gutters and downspout splash blocks after a hail event, making gutters one of the easiest ground-level places to spot early evidence of impact. Dents in the gutters and downspouts themselves also help establish the size of the hail that hit your property.

Can I tell if my roof has hail damage just by looking from the ground?

Not reliably. Most hail damage is not visible from the ground or from inside the home, especially on steep-slope roofs. Ground-level clues like granules in gutters, dented AC units, or damaged window screens can suggest a storm impacted your property, but a professional inspection on the roof surface is the only way to confirm actual damage.

Does hail damage metal or tile roofing differently than shingles?

Yes. Metal roofing typically shows cosmetic dents, damage to exposed fasteners, and cracked or chipped paint coatings rather than punctures. Tile is more brittle and can crack from hailstones under 1 inch in diameter, which exposes the underlayment beneath and creates a leak pathway if not addressed.

How soon should I get my roof inspected after a hailstorm?

As soon as possible, even if you see no interior symptoms. Hail damage that goes uninspected often worsens over 12 to 24 months as granule loss accelerates water intrusion into the asphalt mat. Getting an inspection promptly also strengthens an insurance claim, since delayed filing gives insurers grounds to attribute damage to wear and tear instead of the storm.
