Wind damage to roof shingles usually shows up as creased, lifted, curled, or missing tabs along the edges and ridges of the roof, plus granule loss and loosened flashing. The tell that separates it from other damage is the pattern: wind works the perimeter and the windward slope, lifting and folding shingles rather than scattering random dents across the field. A shingle can be wind-damaged and still lie flat, so the crease line matters more than whether anything blew off.
This guide covers what wind damage looks like from the ground and up close, how much wind it actually takes, and how to tell wind damage apart from hail damage and ordinary aging before you call a contractor or file a claim.
What does wind damage look like on roof shingles?
Wind damage on asphalt shingles appears as six repeatable signs: a horizontal crease across the shingle face, lifted or unsealed tabs, curled corners, fully missing shingles, exposed or scoured granule loss, and bent or displaced flashing. Most of it clusters at the roof edges, hips, and ridge, because uplift pressure is highest where the wind first catches the roof plane.
- Creased shingles. A wind-lifted shingle that folds back leaves a fold line where granules rub off, usually a lighter horizontal streak. A creased shingle has a broken seal and a fatigued mat, so it counts as failed even after it lies flat again.
- Lifted or unsealed tabs. Wind breaks the factory adhesive strip that bonds each shingle to the one below. The tab may not look damaged, but it lifts freely by hand and reseals poorly, leaving the next gust an entry point.
- Curled corners. Repeated flexing turns up the bottom corners of tabs. Curling from wind concentrates on the windward slope, unlike age curling that spreads evenly across the whole roof.
- Missing shingles. Bare patches, or shingles in the yard, mean the seal and nails let go. Missing tabs expose the underlayment and the shingle course beneath to water within hours.
- Granule loss. Wind-driven grit and debris scour the surface coating, leaving smooth, shiny, or darker patches. A rush of granules in the gutters after a storm is often the first sign.
- Damaged flashing. Wind bends or loosens the metal at chimneys, valleys, and sidewalls, opening gaps that leak long after the storm.
How much wind does it take to damage shingles?
Unsealed or aged tabs can lift at gusts of 45 to 57 mph, below the 58 mph threshold the National Weather Service uses to log damaging thunderstorm wind. A correctly installed, still-sealed shingle roof resists far more, because modern asphalt shingles are rated to 90, 120, or 150 mph. The gap between those numbers is almost always the sealant bond and the nailing, not the shingle itself.
| Wind speed | Typical effect on shingles |
|---|---|
| 45 to 57 mph gusts | Unsealed or aged tabs lift and crease; new, sealed shingles usually hold |
| 58 to 74 mph (damaging thunderstorm) | Creasing and unsealing across the windward slope; poorly nailed tabs blow off |
| 75 to 95 mph (Category 1 hurricane range) | Widespread missing shingles, torn tabs, flashing displacement |
| Above 95 mph | Large field losses, exposed decking, structural damage possible |
Asphalt shingles carry a wind rating tested under ASTM D7158 (Class D at 90 mph, Class G at 120 mph, Class H at 150 mph) or the older fan-based ASTM D3161 (Class A at 60 mph, Class D at 90 mph, Class F at 110 mph). Most architectural shingles sold today are Class H or Class G. That rating only holds if the shingle was installed to the manufacturer spec, which in high-wind zones means six nails per shingle placed in the nail line and, on cold installs, hand-sealed tabs. Improper nailing is the reason a rated roof can fail at half its label speed, and it is often why a claim gets contested. For the causes behind tabs letting go, see why shingles blow off a roof.
Wind damage vs hail damage vs normal aging
The single most useful skill in reading a shingle roof is telling wind damage from hail damage and from ordinary wear, because they get repaired and claimed differently. Wind leaves directional, edge-heavy damage with creases and missing tabs. Hail leaves random circular bruises with soft spots. Aging spreads uniform curling and granule thinning across the entire roof with no storm pattern.
| Feature | Wind damage | Hail damage | Normal aging |
|---|---|---|---|
| Pattern | Directional, worst on windward edges, hips, ridge | Random, scattered across all slopes | Uniform across the whole roof |
| Signature mark | Horizontal crease, lifted or missing tab | Round bruise or dent, often 0.5 to 2 inches | Even curling, thinning granules |
| Granule loss | Streaked along creases and scour lines | Circular clusters exposing black mat | Gradual, roof-wide |
| Feel underfoot | Loose, liftable tabs | Soft, bruised spots (like a bruised apple) | Brittle, firm |
| Timing tie | Follows a windstorm, one direction | Follows a hailstorm | No storm event |
If the marks are round and soft rather than creased, you are likely looking at impact damage instead. Compare the two side by side with hail damage to roof shingles. Mixed storms produce both at once, which is why adjusters document them separately on the same claim.
Where wind damage shows up first
Wind damage concentrates on the windward slope and along every roof edge: eaves, rakes, hips, and the ridge. Uplift pressure peaks at these transitions because the wind accelerates as it bends over the roof plane, so a shingle at the ridge sees more force than one in the middle of a slope. Older, sun-baked shingles that have lost their seal fail here first.
Check the ridge cap and the first two courses at each rake edge before anything else. On the ground, scan for a shingle that sits slightly proud of its neighbors, a subtle shadow line, or a color streak where granules rubbed off. Binoculars from the yard catch most of this without a ladder, which is the safer way to start.
Interior signs of wind-damaged shingles
Wind damage often announces itself inside the house before it looks dramatic outside. Brown or yellow water stains on ceilings and upper walls, a persistent damp smell in the attic, or daylight visible through the roof deck all point to shingles or flashing that let go in a storm. Interior signs mean water has already found the gap.
Attic inspection after a windstorm is worth ten minutes: look for wet insulation, dark streaks on the underside of the decking, and drips near valleys or the chimney. Tracing a stain back to its roof source is rarely directly above the stain, since water travels along rafters before it drops.
What to do after you spot wind damage
Move in order: document first, protect second, then get a professional assessment. Photos taken before any temporary repair protect both your safety and a potential insurance claim, since an adjuster needs to see the original condition.
- Photograph everything from the ground. Wide shots of each slope plus zoomed images of creased, lifted, or missing shingles, dated the day of the storm.
- Note the storm. Record the date, peak gust if reported, and direction. This ties the damage to a covered event.
- Tarp active leaks only if safe. A weighted tarp over an exposed area buys time. Do not climb a wet or steep roof; that is a fall risk, not a fix.
- Get a professional inspection. A roofer or licensed inspector can walk the roof, lift tabs to test seals, and separate wind from hail and age.
- Call your insurer if damage is widespread. Confirm your wind deductible and whether the policy pays actual cash value or replacement cost.
Avoid nailing down lifted tabs yourself before an inspection. A creased shingle that gets face-nailed reads as a pre-existing repair and can weaken a claim. For the fix side, cost, and timeline once damage is confirmed, see wind damage roof repair.
Repair or replace a wind-damaged shingle roof?
Isolated wind damage on a roof with life left usually calls for spot replacement of the affected shingles and reflashing. Widespread unsealing, a roof past 15 years, or damage across multiple slopes tends to push toward full replacement, because resealing thousands of fatigued tabs is not reliable. The deciding factors are how much of the roof lost its seal and how old the shingles are.
| Damage extent | Typical action | Rough cost range |
|---|---|---|
| A few creased or missing shingles | Spot repair, reseal, replace flashing | $200 to $600 |
| One slope unsealed or torn | Section repair or partial replacement | $1,000 to $10,000 |
| Multiple slopes, aged roof | Full replacement | $15,000 to $30,000+ |
Ranges vary by region, roof size, pitch, and shingle grade, so treat these as planning numbers rather than a quote. Whether insurance pays depends on your policy and the age of the roof, and many carriers pay actual cash value on older roofs. See whether insurance covers wind damage to a roof for the claim path.

Frequently asked questions
What does wind damage look like on roof shingles?
It looks like horizontal creases across the shingle face, tabs that lift by hand because the seal broke, curled corners, fully missing shingles, and streaked granule loss. Damage concentrates on the windward slope and along edges, hips, and the ridge. A creased shingle is damaged even if it lies flat again, because the seal is broken and the mat is fatigued.
How much wind does it take to damage shingles?
Unsealed or aged tabs can lift at 45 to 57 mph gusts, below the National Weather Service damaging-wind threshold of 58 mph. Correctly installed shingles are rated to 90, 120, or 150 mph under ASTM D7158, but that rating only holds with proper nailing and an intact sealant bond. Poor installation is why a rated roof can fail at half its label speed.
Can wind damage shingles without blowing them off?
Yes. The most common wind damage is a broken sealant bond and a crease, not a missing shingle. An unsealed tab looks fine from the ground but lifts freely and lets water and the next gust underneath. This hidden damage is why a roof can pass a glance yet leak in the following storm, and why lifting tabs to test the seal matters during inspection.
How do you tell wind damage from hail damage?
Wind damage is directional and edge-heavy, with creases, lifted tabs, and missing shingles along the windward slope. Hail damage is random and scattered across all slopes, showing round bruises or dents with soft spots and circular granule loss. Wind follows one direction; hail hits everywhere. Mixed storms cause both, so adjusters document them separately on the same claim.
Does homeowners insurance cover wind damage to shingles?
Wind is a covered peril on most standard homeowners policies, so wind damage to shingles is often covered after your deductible. Payout depends on whether the policy pays replacement cost or actual cash value, and older roofs frequently get depreciated. Some coastal states apply a separate, higher wind or hurricane deductible, so confirm the terms before you file.
Should you repair or replace a wind-damaged shingle roof?
Repair when the damage is a few isolated shingles on a roof with years of life left. Replace when multiple slopes lost their seal, the roof is past roughly 15 years, or resealing large areas would be unreliable. The deciding factors are how widespread the unsealing is and how old the shingles are, not just how many tabs blew off.
