What counts as storm damage to a roof?
Storm damage is harm to the roof from a sudden weather event: wind that tears off or lifts shingles and metal, debris and limbs that puncture the surface, hail that bruises shingles, and wind-driven rain that gets into openings the storm created. It is different from wear and tear, which builds slowly from sun and age, and insurers treat the two very differently.
On the Galveston County mainland, the storms that matter most are tropical systems during the Atlantic hurricane season, which runs from June 1 to November 30, along with strong spring and summer squall lines. Hurricane Ike in 2008 spared Texas City from flooding thanks to the levee, but its winds and rain still damaged roofs. Hurricane Beryl in July 2024 came ashore as a Category 1 and stripped shingles across the region.
The damage that hurts most later is often the least visible. Shingles that were lifted and resettled look normal from the street, yet their seal is broken, and they become the next leak.
How storm-damaged roofs are repaired
Storm repair usually happens in two stages. First comes the dry-in: tarps fastened over battens, or temporary patches, to stop more water from entering while the insurer, the roofer and the weather line up. The roofer photographs the damage before covering it.
Second is the permanent repair. Depending on the extent, that means replacing torn and lifted shingles and hand-sealing loose tabs, rebuilding ridge caps, re-fastening or replacing metal panels and trim, replacing damaged decking and underlayment, and fixing gutters and flashing that were pulled loose. When damage is spread across most of a slope or the whole roof, replacement of those slopes may be the sensible scope.
In Galveston County, permanent roof work that reaches the deck generally has to meet the windstorm building code, and TWIA coverage depends on a WPI-8 certificate of compliance. The certificate comes from a Texas Department of Insurance appointed inspector or a licensed engineer who checks the work while it is being done. Arranging that inspection is part of planning the repair, not something to remember afterward.
Signs a storm damaged your roof
- Shingles, ridge caps or metal trim in the yard or street
- Exposed underlayment or bare wood visible from the ground
- Tabs that look raised, creased or out of line
- Limbs on the roof or scrape marks along the eaves
- Dented gutters, vents or metal panels after hail
- New ceiling stains in more than one room
- Gutters pulled away from the fascia
- Granules washed out at the downspouts after the storm
How storms damage mainland roofs
Wind uplift does the most. As wind flows over a roof, it creates suction on the surface, strongest at the edges, corners and ridge. That is why damage tends to start at the rakes and eaves and peel inward. Shingles installed with too few nails or nails placed too high give way first.
Wind-driven rain is the second blow. Tropical rainbands push water sideways and even upward, into ridge vents, under lifted tabs, past flashing tops and through any opening the wind made. Roofs that never leak in normal weather can leak in these conditions.
Flying debris and trees cause punctures. Limbs from live oaks and other yard trees can break through shingles and decking, and loose items blown off neighboring properties dent and tear metal.
Finally, time does its part. A roof that took minor damage in one storm and was not checked often fails in the next, because the broken seals and loose fasteners give wind an easier start.
What to do and check after the storm
- Make sure everyone is safe and stay clear of downed lines; call 911 or the utility for those.
- Photograph the roof from all sides of the yard, plus every interior stain, before anything is moved or covered.
- Catch water inside with buckets and move belongings away from drips.
- Report the damage to your insurer and note the claim number.
- Keep receipts for tarps and any emergency work.
Take a short video walking the full exterior and interior with the date visible on your phone. It is quicker than dozens of photos and shows the damage in context for the adjuster.
The roofer's visit after a storm
- Document. The roofer photographs each damaged area, slope by slope, including lifted tabs.
- Dry-in. Openings are covered with battened tarps or temporary patches if rain is coming.
- Assess. They inspect decking from the attic, test shingle seals and check flashing, vents and gutters.
- Explain. You get a written scope that separates storm damage from older wear.
- Coordinate. The scope can be shared with your adjuster, and the windstorm inspection is planned if needed.
- Repair. Permanent work is completed, with the inspector visiting during the job where required.
Factors that shape storm repair
| Factor | Effect on the job |
|---|---|
| Extent of damage | Spot repairs versus replacing whole slopes. |
| Deck damage | Brings in deck replacement and windstorm requirements. |
| Insurance process | Adjuster visits and approvals set the timing. |
| Windstorm inspection | Inspections during the work must be scheduled. |
| Regional demand | After a big storm, roofers and materials are stretched across the area. |
Insurance and windstorm paperwork, in plain terms
Many mainland homes carry two policies that touch the roof. Wind and hail coverage in the coastal area often comes through the Texas Windstorm Insurance Association or another windstorm carrier, while the homeowners policy covers other perils. After a storm, check which policy applies before calling, so the claim goes to the right place the first time.
Keep a simple folder for the claim: the claim number, the adjuster's name, every photo and video, receipts for tarps and emergency work, and the roofer's written scope. When the permanent repair needs windstorm certification, add the inspection dates and the WPI-8 itself once it is issued. That certificate matters again when the house is sold or the policy renews, so store it with your deed and insurance papers.
If an adjuster and a roofer disagree about what was damaged, ask the roofer to point out each item in photos and to separate storm damage from older wear in writing. Clear documentation settles most of those disagreements faster than a phone argument.
When storm damage is an emergency
Treat it as urgent when there is an open hole in the roof, a tree on the house, water pouring through ceilings, or water near electrical fixtures. In those cases, safety and a temporary cover come first, and the paperwork follows.
Stay off the roof in wind and rain, and after a storm watch for weakened decking and loose debris. If a tree has hit the house or the structure looks unsafe, get everyone out and call 911.
Storm damage questions
What is a WPI-8?
The Texas windstorm certificate of compliance. In TWIA's coastal area, which includes Galveston County, it shows that roof work met the windstorm building code and keeps the home eligible for TWIA coverage.
Can I make repairs before the adjuster comes?
Temporary repairs that stop more damage, such as tarping, are normally expected; keep receipts and photos. Permanent repairs are best held until the insurer has seen the damage, unless they tell you otherwise.
My shingles are all there. Could the roof still be damaged?
Yes. Wind can break the seal under shingle tabs without removing them. Those tabs lift and leak in later storms, which is why an inspection after a major blow is worth it.
Who handles TWIA versus my homeowners policy?
In the coastal area, wind and hail are often insured separately through TWIA or another windstorm policy, while other perils sit with the homeowners policy. Check your own policy documents or ask your agent.
How do I spot a storm-chasing contractor?
Be wary of door knockers who want payment up front, offer to waive your deductible, or cannot show local registration and insurance. Take time to check anyone before you sign.
Does hail damage roofs here?
Hail is less frequent near the coast than inland, but it does happen with spring storms. Bruised shingles and dented vents are the signs a roofer looks for.
