Wind damage to a Houston roof shows up as creased shingles, lifted or missing tabs, exposed nail lines and bent flashing, most often along edges, ridges and the side of the house that faced the storm. Photograph what you can see from the ground, cover any opening that leaks, and have the roof inspected before you file a claim.
Hail gets the headlines, but in north Houston we document just as many roofs hurt by wind: summer thunderstorms with straight-line gusts, squall lines that roll through at night, and the outer bands of tropical systems. Wind damage is easy to miss because much of it hides in plain sight. A shingle can be lifted, folded back and dropped into place again, looking normal from the driveway while its seal and its strength are gone. This guide explains what wind actually does to a shingle roof and what to do about it.
How strong does wind have to be to damage a roof?
There is no single number, because the answer depends on the roof as much as the storm. The National Weather Service classifies a thunderstorm as severe when it produces winds of at least 58 mph, and NOAA notes that damaging straight-line winds come from ordinary thunderstorms, not only hurricanes. Shingles carry wind ratings from standardized lab tests, which Professional Roofing magazine explains here, but a rating assumes the shingles were nailed correctly and are still sealed. An older roof with brittle shingles or weak seal strips can lose tabs in gusts well below its original rating.
What does a creased shingle look like, and why does it matter?
When wind gets under a shingle tab, it lifts the tab and bends it backward. The bend happens at the weakest point, usually just above the nail line, and it leaves a straight horizontal crease across the shingle. When the gust passes, the tab often falls back flat. From the ground you may see nothing, or only a faint line where the granules cracked.
That crease matters for three reasons. The fiberglass mat inside the shingle has been bent past its limit, so the tab is weaker. The seal strip that held it down is broken. And the nails beneath it may have been pulled partway up. A creased shingle is usually the next one to tear off in the following storm, and the opening it leaves is where water gets in.
What are lifted tabs and broken seal strips?
Asphalt shingles have a strip of adhesive that bonds each course to the one below it after the sun warms the roof. That bond is a large part of a shingle's wind resistance. Wind can break it without creasing the tab, leaving shingles that flutter in the next breeze. Sometimes a roofer can hand-seal unsealed tabs following the manufacturer's instructions. A creased tab is different: sealing it down does not repair the damaged mat, so it normally needs to be replaced.
Where should I look for wind damage?
Wind loads are highest at corners, eaves, rakes and ridges, so damage clusters there. Use this table from the ground, with binoculars if you have them.
| What you see | Where it usually shows up | How urgent |
|---|---|---|
| Missing shingles, exposed underlayment or wood | Rakes, eaves, corners, the storm-facing slope | Urgent: cover it before the next rain |
| Horizontal lines or bends across shingles | Upper courses near edges and ridges | Schedule an inspection soon |
| Tabs that lift or flutter in a breeze | Edges, ridge caps, around vents | Schedule an inspection soon |
| Missing or loose ridge caps | The peaks of the roof | Soon; ridges leak in driving rain |
| Bent drip edge, loose flashing or vents | Roof edges, walls, chimneys, pipes | Soon; these are common leak points |
| Branch strikes or punctures | Under or near trees | Urgent if the deck is punctured |
| New ceiling stain or drip | Inside, below the damaged area | Urgent |
Also walk the yard. Shingle pieces, ridge caps or strips of metal on the ground tell you where to look. Keep them; they help identify your shingle line and document the event.
What should I do in the first few days after a windstorm?
- Stay safe and off the roof. Watch for downed power lines and hanging limbs. A wind-loosened roof surface is slippery and unpredictable.
- Photograph and write down the date. The Texas Department of Insurance recommends you take pictures and video and list the damage inside and outside. Note the date and time of the storm; the NWS Houston/Galveston office posts local storm information.
- Stop water from getting in. Most policies expect you to take reasonable steps to prevent further damage, and to keep receipts. If shingles are missing over living space, an emergency roof tarp is the usual answer; our roof leak emergency guide walks through the first hours.
- Get an inspection before permanent repairs. Once damaged shingles are replaced, the evidence is gone. Document first, then repair.
- Decide about a claim with the facts in hand. Knowing the scope first helps you judge whether a claim makes sense against your deductible.
Can a few wind-damaged shingles be repaired, or does the roof need replacing?
Often a repair is enough. If the damage is limited to a few areas, the surrounding shingles are still flexible, and a matching shingle is available, replacing the damaged pieces is the right call. In our preliminary ranges, roof repairs typically run $450 to $1,900 or more, and an emergency tarp runs $350 to $950.
The picture changes when creases run across a whole slope, when the shingles are so brittle that lifting one to replace its neighbor cracks it, or when the shingle line has been discontinued. Then the repair scope can grow to a slope or the full roof. What your insurer pays for is the insurer's decision under your policy; our part is to document the condition clearly enough that the decision rests on facts.
How do I document wind damage for an insurance claim?
Wind damage is harder to photograph than hail, so the documentation has to be deliberate. When we inspect, we photograph every slope by direction, capture creases in close-up with a reference for scale, record unsealed tabs, note missing pieces and damaged flashing, and measure the roof. That file goes to you. If you decide to file, our guide on how roof insurance claims work in Texas explains the next steps, and our claim documentation page shows how we organize the evidence.
Storm Bolt Roofing is a roofing contractor, not a public adjuster. We document damage and answer technical questions; your insurer decides coverage. And under Texas Insurance Code Chapter 707, no contractor may waive, rebate or absorb your deductible.
Wind damage questions from Houston homeowners
Does homeowners insurance cover wind damage to my roof in Texas?
Many Texas home policies cover wind damage, but not all. TDI notes that some coastal policies, including parts of Harris County along Galveston Bay, exclude wind and hail, which is sold separately. Check your declarations page and ask your agent; your insurer decides each claim.
Can a creased shingle just be glued back down?
Not reliably. Sealing holds the tab flat but does not repair the bent mat inside it, so the shingle stays weak at the crease. Creased shingles are normally replaced. Unsealed tabs without a crease can sometimes be hand-sealed.
How soon after a windstorm should I have my roof inspected?
As soon as it is safe and practical, and before the next rain if anything is missing. Reporting promptly also matters, because your policy sets how quickly you must give notice of a loss.
