You're standing in your Edmond driveway the morning after a severe weather event, looking at damage scattered across your yard. Shingles on the lawn. Dents in the gutter guards. A piece of flashing bent at an odd angle. The storm brought both straight-line winds and marble-sized hail, and now you're trying to figure out what actually damaged your roof—and why that distinction matters for your insurance claim.
Wind damage and hail damage look different, behave differently, and sometimes get handled differently by insurance adjusters. Understanding what you're dealing with helps you document the damage correctly and communicate effectively when filing your claim.
How Wind Damages Your Roof
Wind works on your roof through lifting force. Straight-line winds or tornado-adjacent gusts hit your home and create suction on the opposite side. That upward pressure tries to peel shingles from their nails. It starts at the edges and corners where the force is strongest.
You'll typically see:
- Shingles lifted or creased along ridge lines and eaves
- Missing shingles in concentrated areas, not scattered randomly
- Exposed nail heads where the seal broke
- Torn or peeled underlayment visible through gaps
- Damaged flashing around chimneys, vents, and roof-to-wall transitions
Wind damage follows patterns. Oklahoma's prevailing winds come from the south and southwest, so north-facing and west-facing roof slopes take the hardest hits. You'll see more lifting on those sections than on south-facing slopes. Architectural features that disrupt airflow—dormers, valleys, complex hip-and-ridge configurations—concentrate wind force and show damage first.
The National Weather Service's Norman office tracks Oklahoma's wind events throughout the year. We get sustained high winds during spring and fall storm systems, not just from tornadoes. A 60-mph straight-line wind event can lift shingles just as effectively as a brief tornado touchdown, especially if your roof's already 10-15 years old and the sealant has degraded.
How Hail Damages Your Roof
Hail works through impact force. Ice balls fall from severe thunderstorms—especially the supercells that form along the dryline from March through June—and they strike your roof at terminal velocity. The damage depends on hail size, wind speed during the fall, and what the hail hits.
Look for:
- Bruising or denting on shingle surfaces—dark spots where granules compressed
- Missing granules in random impact patterns
- Cracked or fractured shingles where the mat broke underneath
- Dents in metal components like vents, flashing, gutters, downspouts
- Damage on all roof slopes facing upward, not directional like wind
Oklahoma experiences more hail days per year than any other state, according to NOAA research published in Weather and Forecasting. Central Oklahoma sits at the peak of that activity. Hail measuring one inch in diameter or larger causes shingle damage that compromises the roof's waterproofing integrity, even if the shingles don't look catastrophically destroyed from the ground.
Hail damage sometimes isn't immediately obvious. A shingle can take a direct hit from three-quarter-inch hail, lose half its granule protection, and still look mostly fine for another year. Then UV exposure degrades the exposed asphalt mat. Thermal cycling cracks the weakened areas. Suddenly you've got leaks that insurance adjusters want to call "wear and tear" instead of storm damage.
Why the Difference Matters for Insurance Claims
Your homeowners policy in Oklahoma covers both wind and hail damage under the same wind/hail peril designation. Your percentage-based deductible applies to either cause. But insurance companies sometimes handle the claims differently based on what caused the damage.
Wind damage tends to be more immediately visible. Missing shingles photograph well. Lifted edges are obvious. Adjusters can see it from the ground.
Hail damage requires more careful inspection. An adjuster walks your roof with a test square—usually a 10x10 section—and counts impacts. They're looking for a minimum threshold of hits per square to justify a full replacement recommendation. Miss those impacts during documentation, and you might get approved for a repair instead of the replacement you actually need.
Many Oklahoma storm events deliver both perils simultaneously. You'll have wind-driven hail hitting the roof at angles, creating impact damage on one slope while lifting shingles on another. Your claim documents everything—wind damage, hail damage, related damage to other components—and the adjuster determines causation and coverage.
What Combined Wind and Hail Damage Looks Like
Storms that bring 70-mph winds and golf ball hail—like systems that have hit Piedmont and Deer Creek—often leave lifted shingles with hail bruising on the exposed underlayment. Flashing torn loose by wind, then dented by hail. Missing shingles and granule loss in the same damaged sections.
Combined damage creates a more urgent situation than either peril alone. Wind lifts a shingle, breaking its seal. Then hail impacts the now-exposed underlayment, which wasn't designed to take direct hits. Or hail weakens a shingle by fracturing the mat, and subsequent wind events tear that compromised shingle loose. The damage compounds.
Photograph both types of damage separately. Take close-ups of hail impacts. Wide shots of missing or lifted shingles. Document the metal components—dented vents and flashing support your claim that the storm delivered significant impact force. The more thorough your documentation, the harder it is for an adjuster to downplay the severity.
Documenting Both Types of Damage Correctly
Start your documentation immediately after the storm passes, while the damage is fresh and before subsequent weather events confuse the timeline. Walk your property with your phone and take systematic photos:
- Overview shots of each roof slope from the ground
- Close-ups of any visible shingle damage, lifted edges, or missing sections
- Photos of debris in your yard—shingles, granules, broken flashing
- Dents on metal components like AC units, gutters, downspouts, vents
Don't climb on your roof yourself. Document what you can safely see from ladders, ground level, or second-story windows. You're not trying to prove damage definitively—you're establishing that a storm event occurred and that your property sustained impact.
Schedule a professional inspection within a few days of the storm. Our inspection approach looks for both wind and hail damage patterns, documenting everything with detailed photos and measurements. That inspection report becomes supporting documentation for your claim. It's not the adjuster's only source of information, but it's evidence that a roofing professional identified damage consistent with the storm event.
Should You File a Claim?
Oklahoma Statutes §36-1250.5 addresses claim filing timelines, allowing up to 24 months for wind or hail damage claims, but homeowners should consult their policy and consider speaking with an attorney for specific guidance. Practical considerations often push homeowners to file sooner. Wait too long, and proving storm causation gets harder. Subsequent weather events add new damage that adjusters can point to as alternative explanations. Normal wear accumulates. Your documentation loses credibility.
Consider filing if you've documented legitimate damage, regardless of whether it's primarily wind, primarily hail, or a combination. Your insurance company has 10 business days to acknowledge receipt of your claim and 45 days to accept or deny it. The clock starts when you file, not when the storm hit.
Most homeowners in Edmond can't definitively say whether wind or hail caused specific damage—and they don't need to. That's the adjuster's job. Your job is to document that a covered peril occurred, that damage exists on your property, and that the damage is consistent with the storm event. The insurance company investigates causation and determines coverage.
Understanding the difference between wind and hail damage helps you communicate clearly during the claims process, recognize what you're looking at during inspections, and make informed decisions about repairs versus replacement. Both perils are serious threats to Oklahoma roofs. Both deserve prompt attention after storms roll through.
