Key takeaways
- A failed garage door can let wind pressurize the house and add uplift on the roof.
- Replacement garage doors in Florida must meet the design pressure for your home and carry product approval.
- Wind-rated doors resist pressure; impact-rated doors also resist flying debris.
- Windows in an impact-rated garage door must be impact-rated glass.
On most Central Florida homes, the two-car garage door is the single largest opening in the building — typically 16 feet wide. That makes it one of the most important parts of your home’s storm protection, and one of the most overlooked.
Why the garage door matters in a hurricane
When a garage door buckles or blows in, wind rushes into the garage. That can pressurize the inside of the house, pushing outward on walls and upward on the roof at the same time the wind outside is pulling on them. It is one of the reasons building-science organizations point to garage doors as a key weak link in older homes.
A properly rated garage door, installed to its approval, keeps that opening closed.
Florida’s requirements
In Florida, a garage door is part of the building envelope. A replacement door must:
- Be rated for the design pressure required for your home
- Carry Florida Product Approval (or an accepted local approval)
- Be installed exactly to its approval — including how it is fastened to the jambs and header
- Be permitted and inspected in most jurisdictions
Wind-rated vs. impact-rated
- Wind-rated garage doors are built and tested to resist a specified design pressure. They typically use reinforcing struts across sections, heavier-gauge hinges and track, and a specific fastening pattern.
- Impact-rated garage doors meet pressure requirements and pass debris-impact testing.
Most inland Central Florida homes need a wind-rated door as a minimum. Impact-rated doors make sense when your home requires impact protection or when you are protecting every opening — often to qualify for the best wind-mitigation insurance credit.
Reading the label
Rated garage doors carry a label, typically on an end stile or inside a section, identifying the manufacturer, model and rating or approval. Leave it in place — inspectors and wind-mitigation inspectors look for it. If your current door has no label, it may predate modern requirements.
Windows
Windows add light and curb appeal, but they must be part of the approved assembly. If the door is impact-rated, its windows must be impact-rated glass. Privacy and decorative inserts are available.
Insulation
Florida garages get hot. An insulated door keeps the garage — and adjacent rooms — cooler and makes the door quieter.
- Polystyrene insulation is a budget option.
- Polyurethane foam, bonded between steel skins, insulates better and makes the door stiffer and quieter.
Openers
If your opener is old, noisy or undersized for a heavier reinforced door, it may be worth replacing at the same time. Belt-drive openers are the quietest; wall-mount units free up the ceiling. Battery backup keeps the door working during power outages — useful after a storm.
Safety note
Garage door springs and cables are under extreme tension. Leave spring adjustment and replacement to professionals.
Style
The garage door can be a third of your home’s front elevation. Raised-panel, carriage-house, flush-modern and full-view aluminum-and-glass designs are all available in wind-rated versions — and matching the garage door to a new front door ties the whole exterior together.
Before hurricane season
- Test the door’s balance and operation
- Inspect tracks, rollers and hinges for damage
- Check the weatherseal at the bottom
- Keep the door closed during a storm
If your garage door has no rating label, is dented or feels flimsy, replacing it is one of the most valuable storm-season upgrades you can make.
Frequently asked questions
How do I know if my garage door is wind-rated?
Look for a label on the door, often on an end stile or inside a section, listing the manufacturer, model and design-pressure rating or product approval. Older doors may have no label at all.
Should I brace my garage door before a hurricane?
Older non-rated doors are sometimes reinforced with temporary bracing kits. A rated door installed to its approval is designed to perform without additional bracing — follow the manufacturer's guidance.
Can I add windows to a wind-rated garage door?
Yes, as long as the windows are part of the approved assembly. For impact-rated doors, the windows must be impact-rated as well.
