Living in South Florida means dealing with hurricane season every year. Your garage door is the largest opening in your home and one of the most vulnerable points during a storm. At CMC Door Service, we bring 20 years of experience to installing and repairing hurricane-rated garage doors across Miami-Dade, Broward, and Monroe County. Here’s everything you need to know about protecting your home with the right garage door.
Why Hurricane-Rated Garage Doors Are Required in South Florida
If you already know you need one and want the design pressures, sizes and prices, that is on the hurricane garage doors service page. This page explains what the approval means.
Florida Building Code requires all garage doors in the High-Velocity Hurricane Zone (HVHZ), which includes Miami-Dade and Broward counties, to meet strict wind resistance standards. These doors must withstand design wind speeds of 175 mph in Miami-Dade and 170 mph in Broward, and pass both large and small missile impact tests. If your garage door fails during a hurricane, the sudden pressure change can blow off your roof and cause catastrophic structural damage to your entire home.
Miami-Dade County Wind Code Requirements
Miami-Dade County has some of the strictest building codes in the nation. All garage doors installed in Miami-Dade must carry a Notice of Acceptance (NOA) from the Miami-Dade County Product Control Division. This certification ensures the door has been tested and approved for use in the HVHZ. At CMC Door Service, every hurricane-rated door we install comes with full NOA documentation and meets or exceeds all local building codes.

Signs Your Current Garage Door Isn’t Hurricane-Ready
Many older homes in Miami, Fort Lauderdale, Hollywood, and the Florida Keys still have garage doors that don’t meet current hurricane standards. Warning signs include visible rust or corrosion on tracks and panels, doors that rattle or shake in moderate winds, missing or damaged weather stripping, single-layer non-reinforced panels, and doors without impact-rated glass windows. If you notice any of these issues, it’s time to book a free inspection with CMC Door Service. We’ll assess your current door and provide honest recommendations for upgrades that fit your budget.
How Much Do Hurricane Garage Doors Cost in Miami?
The cost of a hurricane-rated garage door in Miami typically ranges from $1,200 to $4,500+ depending on the size, material, and design. Single-car doors start around $1,200 to $2,500, while double-car doors range from $2,000 to $4,500 or more. Factors that affect pricing include the wind rating level, insulation value (R-value), material choice such as steel, aluminum, or wood, window options with impact glass, and custom design features. We offer flexible financing options to make hurricane protection affordable for every South Florida homeowner.
Garage Door Maintenance Tips for Hurricane Season
Even the best hurricane-rated garage door needs regular maintenance to perform at its best when a storm hits. Our recommended pre-hurricane season checklist includes inspecting and lubricating all moving parts including springs, rollers, and hinges, testing the auto-reverse safety feature on your opener, checking weather seals and bottom rubber for cracks or gaps, tightening all hardware and bracket connections, verifying the door is properly balanced, and testing the manual release in case of power failure. CMC Door Service offers comprehensive preventative maintenance packages starting at affordable rates. Regular maintenance can extend the life of your garage door by 10+ years and ensure it’s ready when hurricane season arrives.

Common questions about hurricane impact approval
What does HVHZ approval actually mean?
HVHZ is the High-Velocity Hurricane Zone, which covers Miami-Dade and Broward. A door approved for it has been tested to the design wind speed for that county and has passed both the large and small missile impact tests. It is a tested certification, not a manufacturer's description.
What wind speed does a garage door have to withstand in Miami-Dade?
Design wind speeds are 175 mph in Miami-Dade and 170 mph in Broward. The pressure figure in pounds per square foot that follows from that depends on the size of the opening and where it sits on the building, which is why two doors with the same rating are not always interchangeable.
What is a Notice of Acceptance and do I need one?
A Notice of Acceptance (NOA) is issued by the Miami-Dade County Product Control Division and confirms the door has been tested and approved for the HVHZ. Every garage door installed in Miami-Dade must carry one. Every hurricane-rated door we install comes with its full NOA documentation.
How do I tell whether my existing garage door is hurricane-rated?
The warning signs of a door that is not are visible rust or corrosion on tracks and panels, a door that rattles or shakes in moderate wind, missing or damaged weather stripping, single-layer non-reinforced panels, and windows without impact-rated glass. If any of those apply it is worth having it inspected, and the inspection is free.
How much does a hurricane-rated garage door cost in Miami?
Typically $1,200 to $4,500 or more. Single-car doors start around $1,200 to $2,500 and double-car doors run $2,000 to $4,500 or more. What moves the price is the wind rating level, the insulation R-value, the material, whether you want impact glass, and any custom design work.
Which hurricane-rated brands do you install?
Clopay, Amarr, Haas Door and Raynor. All four engineer specifically for South Florida wind load requirements, and between them they cover everything from a single-car residential door to a large commercial rolling door.
What happens if my garage door fails during a hurricane?
The garage door is the largest opening in most homes. If it fails, the sudden pressure change inside the building can lift the roof off and cause structural damage to the whole house. That is the reason the code treats it as seriously as it does.
