    The short answer

    A roof may have hail damage if you see bruised or missing shingle granules, dents in soft metal, cracked shingles, damaged vents, gutter dings, or new leaks after a storm. Because many signs are subtle from the ground, a professional inspection is the safest way to confirm the extent of damage.

    Common signs of hail impact

    Hail often leaves a pattern across exposed roof surfaces and metal details. The roof may look fine at first, but granule loss and bruising can shorten shingle life and make future leaks more likely.

    • Dark impact marks or exposed asphalt on shingles
    • Granules collecting in gutters or at downspouts
    • Dents on gutters, vents, flashing, or metal roof accessories
    • Cracked or split shingles after severe weather
    • Fresh ceiling stains or attic moisture after a storm

    What size hail can damage a roof?

    There is no single hail diameter that guarantees roof damage. Small hail can affect an older or already weakened roof, while a newer system may withstand larger stones without functional damage. Wind speed, hail density, impact angle, storm duration, shingle age, material type, roof slope, and previous wear all influence the result.

    Use hail size as a reason to look more closely, not as proof that a roof is damaged or undamaged. If nearby gutters, vents, siding, screens, vehicles, or soft metal show fresh impact marks, document the conditions from the ground and schedule a roof inspection.

    What to do after a hail storm

    Document what you can safely see from the ground, note the storm date, and avoid climbing on a wet or damaged roof. A roofing inspection can separate cosmetic marks from functional damage and create the photos and notes needed for next steps.
