Wind Damage vs Hail Damage: How to Tell Them Apart
Texas storms often bring wind and hail together. Wind vs hail roof damage looks different, fails differently and calls for different repairs. Here is how to read both.

Why the difference matters
Hail damages a roof from above, by impact. Wind damages it from the edges, by lifting. The first leaves scattered marks across the surface. The second tears, creases or removes shingles, usually along edges, ridges and corners.
Knowing which one you have changes the fix. Hail damage spread across a whole slope can mean replacing that slope or the roof. Wind damage is often localized and repairable, unless the shingles have lost their seal across a wide area. Many roofs show some of each, and the repair has to account for both. It also changes how you describe the damage to your insurer, since some policies treat wind and hail under a separate deductible. Coverage always depends on your policy and on the insurer's decision.
There is also a timing difference. Wind damage is usually obvious within days: a shingle in the yard, a bare patch on the roof, a leak at the next rain. Hail damage often stays quiet for months while bruised shingles slowly lose granules. Homeowners who only check for the obvious tend to find the hail damage when it is much harder to tie to one storm.
What hail damage looks like
Random round marks
Impacts scattered across the slope with no line or pattern, heavier on the side the storm came from.
Bruises and soft spots
Dark circles where the shingle gives a little under light pressure. The mat underneath may be fractured.
Granule loss in spots
Small bald circles that expose black asphalt or the fiberglass mat.
Dented soft metal
Dimples on gutters, downspouts, vents, flashing and the AC unit fins.
What wind damage looks like
Missing shingles
Whole shingles or tabs gone, leaving the underlayment or older layers exposed. Usually near edges, ridges or corners.
Creased shingles
A horizontal fold line across the shingle where wind lifted it and it bent back. The shingle may still be in place but has lost strength.
Broken seals
Shingles that lift easily by hand because the adhesive strip let go. They will fail in the next storm.
Lifted flashing and ridge caps
Metal flashing pulled loose and ridge caps cracked or missing, which opens a path for water.
Debris impact
Gouges and punctures from branches or flying objects, often in a line or a cluster.
When both hit the same roof
In a Texas thunderstorm, wind and hail usually arrive together. A roof can show hail impacts on the slope that faced the storm and wind damage on the edges and ridges. Hail can also break the seal on shingles, which makes them easier for the next wind to lift. That is why a roof can look fine after the hail and then start losing shingles weeks later.
The safest approach is to document everything at once. Photos of each type of damage, with the date of the storm, help your roofer decide on the repair and give you a clear record if you choose to file a claim. If hail is the main concern, our guide on how to identify hail damage on asphalt shingles goes deeper.
Some marks are neither wind nor hail. Blisters from heat leave small pits with sharp edges. Normal aging wears granules evenly, worst on the sunniest slopes. Foot traffic leaves scuffs along a path, and branches scrape in arcs under the tree. A good inspection names each mark for what it is, instead of calling everything storm damage. That honesty protects you: a report that inflates damage can create problems with your insurer, and one that misses it leaves you paying later.
If you already have a leak after the storm, follow our steps on what to do after a hailstorm damages your roof: contain the water, photograph it and get the area covered before the next rain.
A quick check after a windy hailstorm
Look at the yard first
Shingle pieces, granules or flashing on the ground are the fastest sign that something came off the roof.
Check edges, ridges and corners
From the ground or a window, look for missing tabs, lifted edges and gaps along the ridge. These are the wind zones.
Check the open slopes
Use binoculars to look for dark spots or scattered marks in the middle of the slopes. That is where hail shows.
Inspect soft metals and gutters
Dents on metal point to hail. Gutters pulled away from the fascia or bent downspouts point to wind or debris.
Check inside
Look at the attic and ceilings for new stains. Wind damage at the edges often shows as water near exterior walls.
Document and schedule an inspection
Take dated photos of everything and book a professional roof inspection before the next rain.
How the repair usually differs
Wind damage limited to a few shingles or a section of ridge is usually a roof repair: replace the missing or creased shingles, reseal or replace the flashing, and check the surrounding seals. If shingles are lifting across large areas, a repair only buys time, because the next strong wind will find the shingles that are still loose.
Hail damage that covers most of a slope rarely makes sense to patch, because the new shingles will not match and the bruised ones around them keep failing. In that case the conversation moves toward roof replacement, especially on an older roof. A replacement is also the moment to consider shingles rated UL 2218 Class 4 for impact and a wind-rated installation that follows the manufacturer's nailing pattern, since both storms will be back. Our storm damage team inspects for both and explains which one you are dealing with.
Material matters too. Hail can dent metal roofs, and whether a dent is only cosmetic or affects how the panel sheds water changes the repair. Tile can crack under hail and slip when wind lifts it. Flat and low-slope roofs are more exposed to wind at the edges and to punctures from debris. The checklist above applies to all of them, but the repair is specific to each material.

Frequently Asked Questions
Is a creased shingle really damaged if it is still on the roof?
Usually yes. A crease means wind lifted the shingle past its limit and bent it. The fold weakens the shingle and often breaks its seal, so it is likely to tear off or let water in during the next storm. Creased shingles are typically replaced, along with a check of the ones around them.
Which causes more leaks, wind or hail?
Wind tends to cause faster leaks because it removes shingles and lifts flashing, leaving openings right away. Hail damage often leaks later, as bruised shingles lose granules and crack over months. Both deserve an inspection after a storm, because the slow damage is the one people tend to miss.
Does insurance treat wind and hail damage differently?
It can. Some Texas policies have a separate wind and hail deductible, and policies differ on what they include. Coverage depends on your policy and on your insurer's decision. Clear photos of each type of damage and a written estimate from a roofer help you present an accurate picture.
Can I just reseal lifted shingles myself?
Climbing a roof after a storm is risky, and resealing only works if the shingle is not creased or cracked. A roofer can tell whether the shingle can be resealed or has to be replaced, and can check the flashing and ridge at the same time.
