Hail damage on a roof appears as dark circular bruises or dents on asphalt shingles where granules have been knocked away, dents or dimples on metal panels, and cracks or chips on tile. You'll often see granules collecting in your gutters after a storm. Because some damage only shows up during a close rooftop inspection — and can worsen through Utah's freeze-thaw winters — a free professional inspection is the safest way to know for certain.
How Hail Damages Utah Roofs
Utah County sits in one of the most active hail corridors in the western United States. Storms rolling through the Wasatch Front can produce hail ranging from pea-sized (half an inch) to golf ball-sized (1.75 inches) between April and September — with peak activity in May, June, and July.
The damage hail causes depends on three things: hail size, wind speed during the storm, and the age and condition of your roof at the time of impact. A 10-year-old roof with worn granules is far more vulnerable to the same storm than a roof installed three years ago.
When hail hits asphalt shingles, it dislodges the protective granule layer — the small, sand-like particles embedded in the shingle surface. Those granules serve as UV protection and water-shedding armor. Once knocked away, the exposed asphalt underneath dries out, cracks, and eventually leaks. The tricky part: this process often takes months or years, which is why Utah homeowners discover leaks long after the storm that caused them.
Utah County's freeze-thaw cycles accelerate hail damage. Water gets into micro-cracks in storm-damaged shingles, freezes in winter, expands, and widens those cracks. A bruised shingle in September can become an active leak by February. This is why inspecting within weeks of a significant storm matters more in Utah than in warmer climates.
7 Signs of Hail Damage to Look For
Some of these you can spot from the ground. Most require getting on the roof — or having a trained contractor do it. Here's what to look for:
Dark Circular Bruises or Dents on Shingles
This is the most common sign of hail damage on asphalt shingles. Look for dark spots, roughly circular, where the shingle surface appears depressed or "soft." These are impact points where hail knocked granules loose. The exposed asphalt looks darker than the surrounding shingle and may feel spongy when pressed firmly with your thumb.
Visible from rooftop only on smaller hail; may be visible from ground on larger hailGranules in Your Gutters and Downspouts
Check your gutters after any significant storm. A small amount of granule loss is normal on aging shingles, but finding a significant accumulation — particularly concentrated after a storm — is a strong indicator of hail impact. Scoop the granules out and look for the gritty, sand-like material that resembles coarse gravel. Also check at the bottom of your downspouts where granules tend to collect.
One of the easiest signs to check from the groundDents on Soft Metal Surfaces
Before climbing on your roof, check metal surfaces at ground level: gutters, downspouts, aluminum window trim, AC unit housing, and any metal flashing visible from the ground. Hail leaves small, random dents on these soft metal surfaces — they look like someone tapped them repeatedly with a ball-peen hammer. If you see dents on these surfaces, your roof almost certainly took impact too.
Best indicator you can assess without getting on the roofCracked, Split, or Missing Shingles
Larger hail — anything over 1.25 inches — can crack shingles outright or split them along the surface. You may also find shingles that have been knocked entirely off the roof by the combination of hail impact and wind. Cracked shingles are an active water intrusion point and should be addressed immediately, not monitored over time.
May be visible from the ground if concentrated in one areaDamaged or Lifted Flashing
Flashing is the metal material that seals transitions on your roof — around chimneys, skylights, vents, and roof valleys. Hail can dent, lift, or crack flashing, creating gaps where water can enter. Flashing damage is especially serious because these are already the most water-vulnerable points on any roof. Look for lifted edges, visible gaps, or obvious denting around any roof penetration.
Often missed by untrained inspectors; always check flashing firstExposed or Damaged Underlayment
In severe hail events, you may be able to see dark patches on your roof where shingles have been stripped away, exposing the underlayment (the black felt or synthetic material beneath the shingles). If you can see this from the ground with binoculars, you have significant damage. The underlayment is not designed for long-term weather exposure — it will fail within months if left uncovered.
Sign of severe damage requiring urgent attentionCeiling Water Stains or Attic Leaks
If hail damage has progressed to active leaking, you'll find evidence inside your home. Look for brown or yellow water stains on ceiling drywall, wet insulation in your attic, or daylight visible through the attic decking. Check your attic within a few days of any major storm — catching infiltration before it reaches living areas saves significantly on repairs. Note that attic leaks can appear far from the actual roof damage point due to how water travels along rafters.
Indicates damage has already progressed — act immediatelySafety note: We don't recommend homeowners get on their own roofs to check for damage. Beyond the obvious fall risk, walking on damaged shingles can worsen the damage and complicate insurance claims. Use binoculars from the ground to look for obvious signs, check gutters and downspouts, and schedule a free professional inspection for a safe, thorough assessment.
Hail Damage by Roof Material
Utah County homes use several roofing materials, each of which shows hail damage differently. Here's what to expect:
| Roof Material | How Damage Appears | Visible From Ground? | Insurance Coverage |
|---|---|---|---|
| 3-Tab Asphalt Shingles | Circular granule loss, dark bruises, cracks, missing shingles | Partially (large hail) | Typically covered |
| Architectural/Dimensional Shingles | Similar to 3-tab but harder to spot; look for soft spots and granule loss | Rarely | Typically covered |
| Metal Roofing | Visible dents, dimples, and paint chips; rarely causes leaks from impact alone | Yes (large hail) | Covered if cosmetic standards apply |
| Concrete or Clay Tile | Chips, cracks, or completely broken tiles; broken pieces may fall off | Sometimes | Typically covered |
| Wood Shake | Splits, cracks, and impact marks with sharp edges (different from weathering) | Rarely | Typically covered |
| TPO/Flat Roofing | Punctures, tears, and bruising; may not be obvious until it rains | No | Varies by policy |
The most important distinction for insurance purposes: adjusters look for functional damage (damage that compromises the roof's ability to protect your home) versus purely cosmetic damage (dents or marks that don't affect performance). A good contractor will document both and advocate on your behalf with the adjuster.
What Size Hail Actually Causes Damage in Utah?
Not all hail is equal. Here's a practical breakdown of what different hail sizes mean for Utah roofs:
- Under ¾ inch (smaller than a penny): Minimal risk to well-maintained roofs. May accelerate wear on aging shingles.
- ¾ inch to 1 inch (penny to quarter size): Can cause granule loss on asphalt shingles, especially on roofs over 10 years old. Inspect if your roof is aging.
- 1 inch to 1.5 inches (quarter to half-dollar size): Likely causes functional damage on most asphalt roofs. High probability of insurance-eligible damage. Inspect promptly.
- 1.5 inches and above (golf ball size and larger): Almost certain damage to all roof types. File an insurance claim. This size hail causes damage to vehicles, siding, and HVAC units as well.
The National Weather Service reports hail events by size after major storms. You can look up historical storm data for your specific zip code to support an insurance claim if you missed the storm date.

What to Do After a Utah Hail Storm
The steps you take in the first few days after a storm directly affect your insurance claim outcome. Here's the right sequence:
- Document the storm date immediately. Save any weather alerts, news coverage, or NWS reports about the storm. Your insurer will need to tie the damage to a specific event. Screenshots of weather apps work.
- Check for interior damage. Look at ceilings, walls, and your attic within 24 hours. If you find active leaks, call a contractor for emergency tarping before a full inspection — most insurers cover emergency protection.
- Inspect soft metal surfaces from the ground. Check gutters, downspouts, window trim, and your AC unit for dents. Photograph everything you find.
- Schedule a free rooftop inspection. Have a qualified contractor get on your roof within 1–2 weeks while storm evidence is fresh. A good inspector will document everything photographically for your claim.
- Contact your insurance company. Once you have the contractor's damage assessment in hand, call your insurer to start a claim. Having documented evidence before you call puts you in a much stronger position.
Utah homeowners typically have 1–2 years to file a storm damage claim, but the evidence degrades over time. UV exposure, foot traffic, and additional weather events make it harder to attribute damage to a specific storm the longer you wait. Inspecting and documenting within 30 days gives you the strongest possible claim position.
Hail Damage Insurance Claims in Utah
Utah homeowners insurance policies typically cover hail damage under the "peril of windstorm and hail" provision, which is standard in most policies. What isn't always standard is your deductible structure — some policies now use a separate, higher percentage-based deductible specifically for hail, rather than your standard flat deductible.
Before filing, review your policy's declarations page for a "hail deductible" or "wind/hail deductible" line item. Some Utah homeowners are surprised to find their hail deductible is 1–2% of their home's insured value rather than their standard $1,000 or $2,500 deductible.
The key factors that determine whether your claim is approved:
- Functional vs. cosmetic damage: Insurance covers damage that compromises your roof's protective function. Purely cosmetic damage (dents without leaks) may or may not be covered depending on your policy.
- Age and condition of roof: If your roof was already at the end of its useful life, the adjuster may apply depreciation, reducing your payout.
- Documentation quality: Claims with professional photography, storm date documentation, and a detailed contractor assessment close faster and at higher amounts.
- Filing timeline: Claims filed promptly after storms are easier to approve than claims filed a year later with ambiguous storm attribution.
A qualified roofing contractor in Utah County can walk the roof with your insurance adjuster — at no cost to you — to advocate for full coverage. This is a standard part of the service reputable roofers offer and is worth requesting when you schedule your inspection.
