Florida wind code
What your door actually has to withstand
Design pressure is measured in pounds per square foot, and it is what a product approval is written against. Find your wind speed, your exposure and whether the house is one storey or two, and the number below is what the door has to be rated for.
Miami-Dade County
175 mph
Exposure C, for most residential buildings
Broward County
170 mph
Exposure C, for most residential buildings
Monroe County and the Keys
Varies
Exposure C or D, varies by island and distance from open water, so it is checked per address
What rated actually means
Struts, heavier track, commercial hardware
A wind rated door is not simply a thicker panel. It carries horizontal steel struts across the back of each section, commercial grade track, and heavier rollers, hinges and springs sized for the load. The whole assembly is tested together, which is why swapping parts on an existing door does not make it rated.
There is nothing to bolt to the floor before a storm and nothing to store the rest of the year. You close it and you lock it.
Design pressure
Minimum required pressures, Exposure C
Positive is the wind pushing the door in. Negative is it pulling the door out, and it is nearly always the bigger number. That is why a door that looks solid from the driveway can still come off its tracks: it gets sucked outward, not pushed inward.

Local rules
Four things that catch people out here
Every door needs an impact rating, windows or not
Miami-Dade and Broward require all garage doors to carry the large missile impact rating, whether the door has windows in it or not. That is stricter than most of the state and it is the single most common reason a door bought elsewhere cannot legally be installed here.
Standard windows are not sold here
Because of the impact requirement, standard glazing is not available in Miami-Dade or Broward at all. If you want windows, they have to be the impact-rated version, which is a different and more expensive product.
A compliant door needs no posts or pins
A properly rated door is reinforced with horizontal struts, heavier track, and commercial-duty rollers and hardware. There is nothing to bolt to the floor before a storm and nothing to store the rest of the year. You close it and lock it.
Your insurer may want more than the code
Code is a minimum. Insurers sometimes require a higher rating than the code does, and many give a wind mitigation credit for a door that exceeds it. It is worth asking them before choosing, because the discount can outlast the difference in price.
Large missile impact
The glass is meant to crack
The large missile test fires a nine pound length of two by four at the door at roughly 50 feet per second, then cycles the pressure thousands of times afterwards. A window that passes usually looks like this: the outer pane is broken right through, and the laminated interlayer still holds it in the frame so the opening never breaches.
That is the whole point of the rating. Nobody is claiming the glass survives undamaged. What matters is that the envelope of the building does.
How it is worked out
Four steps to your rating
We do this for you on the estimate, but it is worth knowing what drives the number.
-
Find your wind speed
From the Florida wind speed map for your address. Miami-Dade is 175 mph and Broward 170 mph for most homes.
-
Find your exposure
B, C or D. Almost everywhere in Miami-Dade and Broward is Exposure C, unless you are within 600 feet of open water.
-
Note the structure
Single storey or two storey, because a taller building sees higher pressure at the same wind speed.
-
Read off the design pressure
Those three together give the positive and negative pressure your door has to be approved for, and the product approval number has to say so.
Exposure B
Urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions.
Exposure C
Open terrain with scattered obstructions, including flat open ground and grassland. All of Miami-Dade and Broward falls here unless it meets the Exposure D definition.
Exposure D
Within 600 feet of the ocean or another body of water at least 5,000 feet across. Design pressures come from the building code official or DASMA TDS-155x.

FAQ
Frequently asked questions
Are hurricane-rated garage doors required in Miami-Dade?
Miami-Dade and Broward sit in the High Velocity Hurricane Zone, the strictest wind-load region in the Florida Building Code. New and replacement garage doors in hurricane impact zones have to carry the required approval for the wind loads at your address.
Why does the garage door matter so much in a storm?
It is the largest opening in most homes. If it fails, wind gets inside and pressurises the structure, which is what lifts roofs. Reinforcing the door protects far more than the garage.
What makes a garage door hurricane-rated?
A combination of gauge and bracing (we use 21-gauge aluminium with WINDCODE reinforcement) plus heavier tracks and hardware, and a product approval covering the design pressures for the location.
Can my existing garage door be reinforced instead of replaced?
Sometimes. Retrofit bracing exists for some doors, but it does not turn an unrated door into a rated one. We will assess your door and tell you whether reinforcement or replacement is the honest answer.
Does a hurricane-rated door lower my insurance?
Many Florida insurers offer wind mitigation credits for code-approved opening protection. Your insurer decides, but we can provide the product documentation for your wind mitigation inspection.
