Your Garage Door Hurricane Checklist — Work Through This in May, Not When a Storm Is Named

Last updated: May 2026 — reviewed against current TWIA requirements for Nueces, San Patricio, and Aransas counties.

We say that with some feeling, because we’ve watched it happen.

Why this city takes garage doors seriously when other places don’t

If you’ve moved here from inland Texas, the amount of attention garage doors get around the Coastal Bend can seem excessive. It isn’t, and the reason is written into this region’s history.

Hurricane Celia made landfall near Corpus Christi in August 1970 and caused extensive structural damage across Nueces County. Forty-seven years later, Hurricane Harvey came ashore near Port Aransas on San Jose Island around 10 p.m. on August 25, 2017, as a Category 4 storm with maximum sustained winds of 130 mph. The National Weather Service recorded a gust of 140 mph at the Aransas County Airport in Rockport. Local authorities reported that nearly every house in Fulton sustained damage, and entire blocks in Rockport were destroyed.

A garage door is the largest single opening in most homes. When it fails under that kind of wind, the garage interior pressurizes and pushes outward on the roof and walls at the same moment the storm pushes inward from outside. That two-directional loading is a documented contributor to the catastrophic roof and wall failures this region has seen firsthand.

That’s why Nueces, San Patricio, and Aransas counties treat garage doors as a regulated building component. It isn’t bureaucracy. It’s a lesson this coast has already paid for.

Before hurricane season: the full checklist

1. Confirm your door’s wind-load rating against current requirements.

Every wind-rated door carries a design pressure (DP) rating, and what your property requires depends on your specific address and exposure category — not a blanket county number. A beachfront property on Padre Island in 78418 faces a higher requirement than a home in Calallen in 78410, even though both are Corpus Christi addresses. If you don’t know your door’s rating, start here. We check it at no charge. See our Nueces County wind codes guide →

2. Test the manual release.

Power outages are routine during Gulf storms. If you can’t operate the door by hand, you may not be able to get a vehicle out or secure the garage during an outage. Pull the release cord, confirm the door moves manually and smoothly, then re-engage it. Do this with the door closed.

This is the item we find failed most often on inspections — not broken, just never exercised. A release mechanism nobody has touched in eight years frequently doesn’t move freely when it finally matters.

3. Inspect springs and cables for corrosion.

A wind-rated panel doesn’t perform to its rating if the counterbalance system behind it is compromised. Look for rust or pitting on the spring coils, fraying at the cable anchor points, and corrosion at the bottom brackets.

In this climate that last one deserves particular attention. The bottom bracket sits low, catches splash-back from rain and irrigation, and is reliably where corrosion starts first — often before there’s visible rust anywhere else on the door. If you’re in Flour Bluff, on Padre Island, along Ocean Drive, or anywhere in North Beach, assume it’s further along than it looks. See our salt air corrosion guide →

4. Check track bracket security.

Loose or corroded wall-mounting brackets are a weak point under wind load. Confirm brackets are tight and show no significant corrosion at the fasteners. On older homes along Ocean Drive and the established Bay Area streets, original brackets have often been quietly corroding at the mounting screws for decades while looking perfectly sound from the driveway.

5. Verify the door’s balance.

Disconnect the opener and lift the door halfway by hand. It should stay put. A door that drifts up or down indicates spring tension issues worth addressing before the season rather than during it.

6. Inspect panels for damage.

Dents, buckling, or corrosion that’s compromised a panel creates a point where wind pressure concentrates. Address it in spring. See our panel replacement service →

7. Confirm weatherstripping condition.

Bottom seals and perimeter weatherstripping won’t stop hurricane-force wind, but degraded seals let wind-driven rain into the garage during the lesser storms that hit far more often than hurricanes do. This is one of the most common sources of water damage we see, and one of the cheapest to prevent.

8. Locate your documentation.

Know where your door’s rating and installation records are. If you need to file a windstorm claim or answer an insurance question — which happens more routinely in Rockport, Fulton, and Port Aransas than most places — having it on hand matters. See our TWIA and TDI certification guide →

What this checklist looks like in your specific neighborhood

• Highest exposure — Port Aransas, Padre Island, Flour Bluff, Rockport, Fulton, Aransas Pass, North Beach. Work through every item, and treat items 1 and 3 as non-negotiable. Multi-directional salt exposure means the corrosion side of this list matters as much as the wind rating.
• Bayfront — Ocean Drive, the Bay Area, Portland, Ingleside. Same list, with particular attention to bracket condition on older housing stock.
• Buffered metro — Southside, Calallen, Annaville, Tuloso-Midway, Gregory, Taft. Corrosion items are less urgent; wind-load verification is not. Requirements apply throughout the county.
• Inland — Robstown, Kingsville, Alice, Sinton, Odem, Bishop, Driscoll, Banquete, Agua Dulce. Design pressure requirements are generally lower this far from open water, but lower isn’t zero. Items 1, 2, and 5 still apply.

When a storm is actually approaching

• Close the door and keep it closed. It’s the largest opening in your home and the barrier keeping wind from pressurizing the structure.
• Do not leave it partially open to “equalize pressure.” This is persistent folk advice and it is wrong. An open or partially open garage door lets wind in rather than relieving anything.
• Move vehicles and valuables away from the door if it’s older or you have doubts about its rating.
• Parking a vehicle behind the door is a last-resort stopgap if you genuinely doubt the door will hold. It is not a substitute for a rated door.

Why bracing kits are a partial answer at best

Temporary bracing kits can add reinforcement to a door that isn’t wind-rated. Honestly, though: they generally don’t bring an older non-rated door up to full TWIA-compliant performance, particularly in the higher exposure categories nearer open water. Better than nothing in a pinch. Not equivalent to a rated system.

After a storm passes

Before operating the door normally, look at it. Check track alignment, panel condition, and whether hardware sits differently than before. A door that took wind stress can look functional while being compromised, and running it can turn a repair into a replacement.

Photograph any visible damage before repairs begin. Storm damage is typically covered where gradual wear is not, and that documentation genuinely supports a claim. See our insurance coverage guide →

Why May, specifically

Scheduling in spring buys you availability, unhurried work, and — this is the part people underestimate — time to actually order a door. Wind-rated doors are frequently special-order items with lead times measured in weeks, and that lead time does not compress because a storm is in the Gulf.

Every year we field calls in late August from people who’d been meaning to get to this since spring. We help where we can. We’d rather see you in May.
