What hail damage looks like on asphalt shingles
On asphalt shingles, hail leaves round or irregular dents that break the surface of the shingle. The damage often appears as a bruise — the shingle may not have a hole, but the protective granules (the gritty coating) are knocked loose or missing in a circular pattern. This exposed area looks lighter or shinier than the surrounding shingle because you can see the darker asphalt underneath.
The dents cluster in groups rather than appearing in a single line. If you see three or more dents within a 10-foot section of roof, hail was likely the cause. The dents are typically the size of a marble or smaller, though larger hail can leave bigger marks. Unlike wind damage, which tears or peels shingles, hail damage is localized impact marks.
Fresh hail damage shows as dark spots or missing granules that stand out against the rest of the shingle. Over time, these areas may collect dirt or algae, making them harder to spot from the ground. This is why inspecting the roof soon after a hail storm matters — the damage is clearest when fresh.
Key Takeaways
- Hail creates round or irregular dents in asphalt shingles with missing or loosened granules, appearing as darker spots or bruises on the surface.
- Multiple dents clustered together in one area are a sign of hail; wind damage typically tears or peels shingles in a different pattern.
- Metal roofs show hail damage as dents or dings, while wood shakes may split or splinter at the impact point.
- Damage is easiest to see within days of the storm; older damage becomes harder to spot as dirt and algae accumulate.
- A professional roof inspector can confirm hail damage and document it for insurance purposes, which is necessary before filing a claim.
How hail damage appears on metal roofs
Metal roofing shows hail damage as dents or dings in the metal surface. Unlike asphalt shingles, metal does not lose granules — instead, the impact leaves a visible depression. The dent may be small and shallow or deep enough to catch your fingernail, depending on hail size and the thickness of the metal.
On standing-seam metal roofs (the kind with vertical ridges), hail dents often appear along the flat panels between the seams. The damage is usually easier to spot on metal than on asphalt because the dent creates a shadow that makes it visible from a distance. Paint may also chip or crack at the impact site, exposing bare metal underneath.
Metal roofs are generally more durable than asphalt in hail, and small dents alone may not require repair. However, if the paint is compromised or the dent is deep enough to trap water, the roof can rust or leak over time. An inspector can determine whether the damage is cosmetic or functional.
Hail damage on wood shakes and other roof types
Wood shakes and shingles respond to hail differently than asphalt or metal. Hail may cause the wood to split, splinter, or crack along the grain. The damage often looks like a gouge or a line running across the shake rather than a round dent. Wood is softer than asphalt or metal, so even smaller hail can leave visible marks.
On tile or slate roofs, hail can crack or break the individual tiles. A cracked tile may not be obvious from below, but it will leak once rain reaches it. Tile damage is often discovered during an inspection rather than spotted from the ground.
Composite or synthetic shingles fall somewhere between asphalt and wood in how they respond to hail. They may dent, crack, or lose surface material depending on their composition and the force of impact.
Where to look for hail damage on your roof
Hail damage is not evenly distributed across a roof. Look first at the south and west-facing slopes, which typically take the most direct impact during a storm. Damage is also more visible on the upper portions of the roof and along ridges and peaks.
Check the roof valleys (where two slopes meet) and around roof penetrations like vents, chimneys, and skylights. Hail can cause damage to flashing and sealant around these areas, which may lead to leaks even if the shingles themselves are intact. Gutters and downspouts may also show dents or damage from the same storm.
If you can safely access your roof or use binoculars from the ground, look for clusters of damage rather than isolated marks. A single dent could be from debris or age; multiple dents in one area point to hail. If the roof is steep or you are uncomfortable climbing, a professional inspector is the safer choice.
The difference between hail damage and other roof damage
Hail damage is often confused with other types of wear. Wind damage typically tears, peels, or lifts shingles, creating irregular edges and exposing the underlayment. Hail leaves dents or bruises with intact shingle edges. Age-related wear shows as widespread granule loss across the entire roof, not clustered in one area. Impact damage from falling branches creates a larger, more jagged mark than hail.
Algae or moss growth can look like dark spots on a roof, but it washes away or brushes off, whereas hail damage is permanent. Thermal cracking (caused by temperature swings) creates long, straight lines running across shingles; hail creates round or irregular marks.
If you are unsure whether damage is from hail or another cause, photograph it and have a professional inspect the roof. Documentation is important if you plan to file an insurance claim, because insurers distinguish between covered hail damage and other types of wear.
When to call a professional roof inspector
You should have a professional inspect your roof after any hail storm, especially if the hail was reported as large (golf-ball size or bigger). An inspector can confirm whether damage is present, assess whether it affects the roof's function, and document findings for an insurance claim.
Many homeowners insurance policies cover hail damage, but the insurer will typically send their own adjuster to inspect before approving a claim. A pre-claim inspection by an independent inspector gives you documentation and a professional opinion before you contact your insurer. Some roofers offer free inspections after storms; others charge a fee.
Do not delay inspection. Hail damage can worsen with rain or additional weather, and insurers may question whether damage occurred during the storm or developed later. Inspecting and documenting damage within days of the storm strengthens any claim you file.
Frequently Asked Questions
Can small hail dents in asphalt shingles cause leaks?
Small dents alone usually do not cause when ready leaks, but they compromise the shingle's protective layer. Once granules are missing, the underlying asphalt breaks down faster when exposed to sun and rain. Over time, this can lead to leaks. If damage is widespread across the roof, replacement may be necessary sooner than it would be otherwise.
How soon after a hail storm should I inspect my roof?
Inspect within 24 to 48 hours if possible. Damage is clearest when fresh, and early documentation helps if you file an insurance claim. Waiting weeks or months makes it harder to prove the damage occurred during the storm rather than from normal wear.
Will my homeowners insurance cover hail damage?
Most homeowners policies cover hail damage, but coverage depends on your specific policy and deductible. Contact your insurer after a storm to report potential damage. They will send an adjuster to inspect and determine what is covered. Some policies have separate hail deductibles that differ from your standard deductible.
What if I find hail damage but the roof is not leaking yet?
Damage that is not currently leaking may still warrant repair or replacement, depending on the extent and your roof's age. A professional can advise whether the damage will likely cause problems soon or whether monitoring is sufficient. If you plan to sell your home, undisclosed hail damage can complicate the sale.
Can I repair hail damage myself?
Small repairs like replacing a few damaged shingles are possible for experienced homeowners, but most hail damage is best handled by a professional roofer. If you file an insurance claim, the insurer may require that repairs be done by a licensed contractor. Improper repair can void your warranty and create new leaks.
