Florida homes face wind conditions that can place significant pressure on garage doors during hurricanes and severe storms.
Because garage doors are among the largest openings in many homes, they are an important part of the building envelope. FEMA notes that garage door failure during high-wind events can allow wind to enter the structure and increase pressure on walls and the roof.
For Sarasota homeowners, that means garage door condition, wind resistance, installation, and product approval can all matter when replacing or evaluating an existing door.
Why Garage Doors Matter During a Hurricane
A double garage door creates a very large opening in the front or side of a home.
During a high-wind event, the door can be exposed to both positive and negative pressure. If the garage door fails, wind can enter the garage and place additional pressure on the rest of the home. FEMA specifically identifies garage doors as vulnerable openings during severe wind events.
That is why wind-rated garage doors, proper installation, and secure attachment are important in hurricane-prone areas.
What Does “Wind-Rated Garage Door” Mean?
A wind-rated garage door is designed and tested to resist a specified amount of wind pressure.
Florida-approved garage doors can have different design-pressure ratings depending on the model, door size, construction, glazing, and intended installation location. Florida product-approval records show that approved garage doors may carry specific positive and negative design-pressure ratings and may have different limits depending on whether the door is impact-resistant.
The correct door is not determined by a single statewide number. The required design pressure depends on factors such as the building location, exposure, building height, opening size, and applicable code requirements.
Sarasota County Uses the Florida Building Code
Sarasota County currently identifies the 2023 Florida Building Code, 8th Edition as its current building code.
For garage doors, wind-load requirements are determined using the applicable structural provisions of the Florida Building Code. Product evaluation documents for Florida-approved garage doors specifically direct installers to determine the required design wind load based on the site and to follow the approved installation drawings.
This means a garage door that is appropriate for one Florida home may not automatically be suitable for another.
Wind Resistance and Impact Resistance Are Not the Same Thing
This is an important distinction.
A garage door can be designed to resist wind pressure without necessarily being impact-resistant.
Florida product-approval records include garage doors that satisfy stated wind-pressure requirements but are specifically listed as not impact resistant, while other versions are approved as impact-resistant.
If a garage door contains windows, the glazing and any required opening protection also need to be considered.
How Can You Tell What Your Existing Garage Door Is Rated For?
Start by looking for manufacturer information or labels on the door.
Wind-rated products may identify information such as:
- manufacturer
- model or series
- design-pressure rating
- installation drawing or approval reference
- applicable testing standard
FEMA recommends checking the door’s product information and installation documentation when evaluating its wind resistance.
If the rating cannot be determined, a garage door professional may be able to help identify the door or evaluate whether replacement should be considered.
Does an Older Garage Door Need to Be Replaced?
Not automatically.
An older garage door may still function well, but age alone does not tell you how the door will perform during severe wind.
Homeowners may want to consider the door’s condition, structural reinforcement, track attachment, hardware, product rating, and whether the installation meets current requirements.
If the door has extensive corrosion, damaged panels, loose tracks, repeated mechanical problems, or no identifiable wind-rating information, it may be worth discussing garage door replacement.
Before Hurricane Season
Before storm season, visually inspect the garage door for:
- loose or damaged tracks
- missing hardware
- significant corrosion
- cracked or damaged panels
- damaged rollers
- worn weather seals
- unusual movement when operating
- any required reinforcement that is missing or damaged
Do not make structural modifications to a wind-rated garage door without confirming that the change is compatible with the approved door system.
