Structural engineers describe garage door failure in a hurricane bluntly: once the door goes, the wind is inside the building. Pressure then builds against the roof structure from underneath, and what began as a door problem becomes a roof problem.
Know what your door is rated for
Florida requires garage doors to meet wind-load requirements statewide. Miami-Dade and Broward fall inside the High-Velocity Hurricane Zone, where the requirements are stricter again. Doors fitted before those requirements tightened are common, and many are not rated for the wind speeds their address now assumes.
Look for a label inside the door, usually on a section or the track, stating the design pressure. If there is no label, assume it is unrated until proven otherwise.
If you do one thing before June, find out whether your door is rated. Everything else on the list is maintenance — that one is structural.

Before the season
Pre-season inspection
- Confirm the door is rated for your address and the label is present.
- Tighten every track bracket and lag bolt — wind finds loose fixings first.
- Inspect the bottom seal; a failed seal lets water in even without wind.
- Test the balance and the auto-reverse.
- Look for rust at the bottom section, especially on coastal properties.
- Confirm the Garage Door Opener has a battery backup, or plan how you will open the door without power.
Bracing kits
If your door is structurally sound but under-rated, a retrofit bracing kit is a legitimate option and far cheaper than replacement. It must be a kit designed and approved for your door — timber propped against the inside is not bracing and does not work.
After the storm
Even if the door still opens, look along the top edge of each section for buckling, check the track for kinks and the cables for slack. Wind damage is often invisible until the door is next cycled, and that first cycle is where hidden damage becomes real damage.
Why the garage door is the one that matters
Ask a structural engineer about hurricane damage to houses and the garage door comes up almost immediately.
One more thing, because it matters. It is the largest opening in the building. If it goes, wind gets inside, and pressure then builds against the roof structure from underneath.
What began as a door problem becomes a roof problem very quickly. We say that from experience, not from a brochure.
Finding out what yours is rated for
There should be a label inside the door, usually on one of the sections or on the track.
This trips people up constantly. It states a design pressure — how much positive and negative pressure the assembly can take. Positive is wind pushing in. Negative is suction pulling out.
Suction is what usually takes a door, which is why anything that only resists inward push is not enough on its own.
No label anywhere? Assume it is unrated until somebody proves otherwise. Most people find this out the expensive way.
Our pre-season checklist
Every visit runs the same way, whatever the original complaint was. It is quicker than it sounds, and it stops us treating a symptom and calling it a fix.
- Confirm the door is rated for your address, and that the label is still there and readable.
- Tighten every track bracket and lag bolt — wind finds loose fixings first.
- Check the bottom seal, because a failed seal lets water in with no wind at all.
- Test the balance and both safety reverses.
- Look for rust at the bottom section, especially within a few miles of salt water.
- Confirm the opener has a working battery backup.
If something on that list is worn but not urgent, we say so and give you a rough idea how long it has left. That way you can plan instead of react. That is not a sales line. It is just how the hardware behaves.
The mistake we see most
Propping timber against the inside of the door and calling it bracing.
Short version? It does not work. Most failures are suction pulling the door outward, and a prop does nothing at all against that.
A retrofit bracing kit engineered and approved for your specific door does work — and it is far cheaper than replacing the door. That is not a sales line. It is just how the hardware behaves.
The short version
If you take one thing away from all of that: a door that is balanced, lubricated and has working safety reverses will outlast one that is not. By years, not months.
Almost everything we get called out to was preventable. Most of it was cheap to prevent, too.
So if any of this sounds like your door, get eyes on it while it is still an inconvenience rather than a breakdown. We would rather do the small job.

Finding out what yours is rated for

Now, the bit nobody mentions. It states a design pressure — how much positive and negative pressure the assembly can take. Positive is wind pushing in. Negative is suction pulling out.
Suction is what usually takes a door, which is why anything that only resists inward push is not enough on its own.
No label anywhere? Assume it is unrated until somebody proves otherwise. You will notice it long before it becomes urgent, if you know to look.
