Two houses on the same street can take the same storm and end up with completely different problems. One loses shingles off the ridge. The other looks untouched until the granules start washing into the gutters.
Wind damage roof problems and hail damage leave different marks in different places. Wind attacks edges, ridges, and corners. Hail scatters impacts across the open field of the roof, usually on the slope facing the storm.
Knowing which one you have changes what gets repaired, what your insurance covers, and how fast you need to move.
Start with location. It’s the fastest tell.
| What to check | Wind damage | Hail damage |
|---|---|---|
| Where it shows | Edges, ridges, corners, rake lines | Scattered across open slopes |
| What it looks like | Lifted, creased, or missing shingles | Round bruises, granule loss, cracked mats |
| Metal surfaces | Bent flashing, loose gutters | Dents in gutters, vents, downspouts |
| Yard evidence | Whole shingles or torn pieces | Granules washed into gutter ends |
| How it progresses | Gets worse as seals keep failing | Fixed at the moment of impact |
| Timing of leaks | Often days or weeks later | Usually only if the deck cracked |
A single Louisiana storm frequently delivers both. A line of storms moving through Denham Springs can drop hail on one slope and tear the ridge cap on another. Check every side of the house, not just the one facing the road.
You can find most of it standing in the yard with a pair of binoculars. Nobody needs to be on the roof.
Wind damaged shingles do not always go missing. A shingle that lifted, flexed, and settled back down looks normal from below but has lost its adhesive seal. That one is the dangerous kind, because it leaks without looking broken. A shingle that lost its seal usually needs a targeted repair rather than a full replacement, as long as the decking underneath is still sound.
Hail damage to shingles is harder to spot from the ground, which is why it goes unclaimed so often.
The impacts themselves leave round bruises where the granules are knocked away and the mat underneath is soft to the touch. They land randomly rather than in lines or patterns, and they show up on the slope that faced the storm.
The easiest evidence is not on the roof at all. Check these soft-metal surfaces first.
If the AC unit and the gutters are dented, the roof almost certainly took impacts too.
Hail also accelerates aging. A roof that survives a hailstorm with no leak can still lose years of service life, because every spot stripped of granules is now exposed to UV. That damage becomes a leak two or three summers later, long after the claim window closed.
Impact-resistant shingles are rated against this under UL 2218. The classes run from Class 1 to Class 4, tested with steel balls from 1.25 inches up to 2.00 inches in diameter, with Class 4 being the most resistant.
Wind does not push down on a roof. It lifts.
As air moves across a roof plane it creates lower pressure above the surface while pressure builds underneath. That difference pulls upward, and the pull concentrates hardest where the wind first catches an edge.
Corners get hit from multiple directions at once, which multiplies the effect. Ridges sit exposed on both slopes. Rake edges along a gable end are where wind gets its first grip.
Once it has that grip, failure spreads inward. This is why construction standards target those exact zones. The FORTIFIED standard from the Insurance Institute for Business and Home Safety calls for ring-shank nails in a tighter pattern, a sealed roof deck, and extra detailing at the drip edge to protect the roof’s most vulnerable line.
Shingle wind ratings are tested under ASTM D3161 Class F and ASTM D7158 Class H. Those ratings assume correct installation, which is where a lot of roofs quietly fall short.
This one catches homeowners in Walker and Prairieville every season.
Wind-driven rain does not need a hole. It needs a shingle whose adhesive seal has released. Rain moving sideways at 50 miles per hour gets under that lifted tab and onto the decking, where it soaks in rather than running off.
Nothing drips during the storm because the water is absorbed by the decking and insulation first. The ceiling stain appears days later, sometimes after the next ordinary rainfall, and by then the connection to the storm is easy to miss.
That delay causes two problems. The damage is worse than it would have been, and the claim is harder to tie to a specific dated weather event.
If a named storm passed over your house, check the attic within 48 hours even if nothing looks wrong from outside.
Stand on solid flooring or a joist. Bring a flashlight and turn it off once you’re up there so your eyes adjust.
Photograph anything you find, with the date. Attic photos carry real weight with an adjuster because they show water intrusion rather than cosmetic wear.
Not every curled shingle came from a storm, and adjusters look hard at this distinction.
Louisiana’s heat and humidity age a roof fast. Daily expansion and contraction makes shingles brittle and curled over time, with no wind or hail involved at all.
The difference is distribution. Normal aging spreads evenly across sun-facing slopes. Storm damage concentrates at edges and ridges for wind, or scatters in random impacts for hail.
Three questions sort most cases.
Evenly worn shingles across an entire slope with a clean yard and a dry attic usually means the roof is simply near the end of its life. That’s a replacement conversation, not a claim.
One local warning. After every major Louisiana storm, out-of-state crews arrive within days offering free inspections and fast signatures. Some are legitimate. Many are gone before the warranty matters. Check that the contractor is licensed in Louisiana and has a physical address you can drive to.
Usually yes, but the deductible is the part that surprises people.
Named storm and hurricane deductibles in Louisiana typically run two to five percent of the insured property value rather than a flat amount. The Louisiana Department of Insurance gives the example of a $250,000 home with a two percent deductible, where the homeowner pays $5,000 before the insurer pays anything.
One protection works in your favor. For policies issued or renewed on or after January 1, 2010, the separate named storm deductible applies on an annual basis across all named storm losses in a calendar year rather than per storm.
The claim timeline is set by statute.
The practical takeaway is that a documented, dated claim moves faster than a vague one. Photos taken within 48 hours are what makes proof of loss satisfactory.
Once the current damage is handled, the next step is making sure the roof is ready to prepare for the next storm.
Within 48 hours if you saw shingles in the yard or the storm was named. Wind-driven rain can soak decking for days before a ceiling stain appears, and early documentation makes an insurance claim considerably easier to support.
Yes, and this is the most commonly missed type. A shingle can lift, flex, and settle back down looking normal while its adhesive seal has failed. It leaks in the next wind-driven rain without ever going missing.
Check the soft metal around your house. Dents on gutters, downspouts, vents, and air conditioner fins mean hail hit hard enough to bruise shingles too. Those surfaces dent at smaller hail sizes than shingles do.
Not always, but the damage does not stop. Every spot where granules were knocked off leaves the mat exposed to UV, which shortens the roof’s life even if there is no leak today. Get it documented while the storm date is still recent.
Named storm and hurricane deductibles are typically two to five percent of insured value rather than a flat dollar amount. On a $250,000 home at two percent, that is $5,000 out of pocket. Your declarations page lists the exact figure.
No. For policies issued or renewed on or after January 1, 2010, Louisiana applies the separate named storm deductible on an annual basis rather than per storm.
