What does wind damage look like on a Triad roof?
Most wind damage in the Triad comes from summer thunderstorm downbursts, not tornadoes. A few strong gusts can tear off ridge caps, crease shingles and drop limbs on a roof in minutes.
Last reviewed against official sources. General information, not insurance or legal advice.
After a strong storm, look from the ground at the ridge, the corners and the side of the house that faced the storm: missing or folded shingles, ridge caps on the lawn, bent drip edge and gutters pulled loose. Wind damage is normally covered by a North Carolina homeowners policy as a sudden loss, subject to your deductible; worn-out shingles that simply fail are not.
Downbursts: the Triad's main wind threat
Short answer: a downburst is a column of rain-cooled air that slams into the ground and spreads out, and it can do tornado-like damage in a straight line.
NOAA's Storm Events Database lists 1,474 thunderstorm wind reports in Guilford, Forsyth, Alamance, Rockingham and Randolph counties from 2006 through 2025, spread over 403 separate days. July had the most (358), followed by June (312) and May (222). The highest measured gusts in that record include about 74 mph at Piedmont Triad International Airport on July 13, 2015, and about 72 mph at Smith Reynolds Airport in Winston-Salem on July 6, 2008 (converted from knots). Most reports are not measured gusts at all but damage: downed trees and power lines.
The Triad logged 1,474 thunderstorm wind reports from 2006 through 2025. On September 18, 2026, the airport (GSO) measured a 69 mph gust. Check edges, ridges and the windward side after a storm like that.
Non-thunderstorm wind
Strong winds also come without storms. NOAA lists high wind events in the Triad on dates such as March 12, 2014, February 14, 2015, March 2, 2018, and February 16, 2025, and Helene's remnants brought damaging wind on September 27, 2024. These winds last for hours instead of minutes, which works shingles loose that a short gust would not.
Checking your roof from the ground
| Look at | Signs of wind damage |
|---|---|
| Ridge and hips | Missing cap shingles, cap pieces in the yard |
| Corners and gable ends | Shingles missing or flipped back |
| Mid-slope | Shingles with a straight crease line, or dark patches where shingles are gone |
| Edges | Bent drip edge, gutters pulled away from the fascia |
| Vents and pipes | Turbine or box vents tilted or gone, loose pipe boots |
| Yard and driveway | Shingle pieces, granules and limbs |
Creased shingles are the hardest to spot. The tab was bent back by the wind and the seal broke, so it may lie flat now and blow off next time. A roofer can check by gently lifting tabs and should photograph each crease.
Why older Triad roofs lose shingles first
Shingles rely on a strip of sealant that bonds each course to the one below. Years of summer heat and winter cold cycles can weaken that bond, and shingles installed in cold weather may not have sealed well. Older three-tab shingles generally have lower wind ratings than modern laminated shingles. When some shingles blow off a roof that otherwise looks fine, it's worth asking a roofer whether the rest are still sealed.
Insurance in North Carolina
- Sudden wind damage is usually covered by the homeowners policy. Unlike the coast, Triad homes don't have NCIUA wind policies, so the claim goes to your regular insurer.
- Check your declarations for a separate wind/hail or named-storm deductible; some policies have one even inland.
- Expect the adjuster to separate storm damage from wear. Dated photos of the roof before the storm help.
- If repaired shingles won't match, ask how your insurer handles matching under its policy.
See reading your policy and wind and hail deductibles.
Recording the storm
- Write down when the worst gusts hit and save the warning from the NWS office in Raleigh (or Blacksburg, for Rockingham County).
- Photograph shingle pieces in the yard where they landed.
- Note damage to fences, sheds, siding and screens too.
- Use the Storm Center to find the storm reports for your area.
After the power comes back
Big Triad wind events often knock out power for a day or more, and roof checks get put off. Once things settle, walk the house again: look for new ceiling stains, check the attic with a flashlight for daylight or wet decking, and look at the roof from across the street. Damage that's reported weeks later is harder to tie to one storm, so note what you find with the date.
Frequently asked questions
How strong does wind have to be to damage a roof?
The National Weather Service calls a thunderstorm severe at 58 mph, and gusts that strong can lift shingles. Older shingles with weak seals can fail at lower speeds.
Is a downburst covered the same as a tornado?
Generally yes. Homeowners policies cover windstorm damage whether it came from straight-line wind or a tornado. Your deductible is the same unless your policy has a special deductible for named storms.
A few shingles blew off. Should I file a claim?
Compare the repair cost with your deductible first. A few shingles may cost less than the deductible to repair, but get the roof checked for creased shingles you can't see from the ground.
Will the insurer pay to replace the whole roof?
Only if the damage warrants it under your policy. Insurers pay to repair storm damage; the whole roof is usually replaced only when damage is widespread or repairs aren't possible.
Policies vary. Check your own policy and ask your insurer or agent about anything that affects your claim. Laws and rules can change; this page reflects official sources as of October 29, 2026. RoofingGreensboro.com is not a contractor, insurer, adjuster or law firm.
