Hurricane Impact Garage Doors in Miami-Dade & Broward

Your garage door is the largest opening in your home, and under Florida’s strictest building code it has to prove it can hold. Garage Door Shield supplies and installs NOA-approved impact-rated doors across Miami-Dade and Broward. Call (305) 998-0991.

Why the Garage Door Fails First

In a major storm, the garage door is usually the first part of a house to give way. It is the largest unsupported opening in the structure, and the only one designed to move.

What happens next is the part homeowners underestimate. Once the door fails, wind enters the garage and pressurizes the interior of the house with nowhere to escape. That internal pressure pushes upward and outward, against the roof from below and against the walls from inside. Roofs are engineered to resist wind pulling from above, not lifting from underneath.

What the Code Requires in Miami-Dade and Broward

Miami-Dade and Broward counties are designated High Velocity Hurricane Zones (HVHZ) under the Florida Building Code. This is the most demanding wind-load standard in the United States, and it applies to every garage door installed in either county.

Wind-load rating. Design wind speeds in Miami-Dade start at 175 mph. Your door must be engineered to withstand the positive and negative pressure those speeds generate across the full door span.

Impact resistance. In HVHZ zones a wind rating alone is not enough. The door must also survive strikes from wind-driven debris, verified through standardized missile impact testing.

Both are certified through a Miami-Dade Notice of Acceptance (NOA), documentation confirming the product passed testing under protocols TAS 201, TAS 202 and TAS 203. Products carrying an NOA are the only ones legally permitted in HVHZ zones. NOAs also require periodic renewal, so an expired NOA can create problems at permit or at sale.

How to Tell If Your Door Is Rated

Check three places, in this order.

The label on the inside of the door. Look along the inside face of the panels or on the track near the top. A rated door carries a permanent label listing the manufacturer, the model, and an NOA number.

Your permit records. If the door was installed with a permit, your county building department has the record and the approved product number on file.

Your wind mitigation inspection report. If you have had one done for insurance, it will state whether your garage door opening is protected.

If you cannot find a label anywhere, the door almost certainly predates current code. Most doors installed before the code tightened following Hurricane Andrew do not meet today’s requirements, and neither do many builder-grade doors installed since.

What Hurricane Rated Doors Cost

A single door installed typically runs $1,200 to $2,400. A double door runs $2,200 to $3,200.

Where you land in the range depends on material, insulation value, window configuration and hardware finish. Every price includes the door, hardware, permit and installation, and every door we install in Miami-Dade or Broward is NOA approved, because nothing else can be permitted here. You will have a written, itemized quote before anything is ordered.

The Insurance Angle

Florida insurers offer wind mitigation credits for homes with verified opening protection, and the garage door counts as an opening. After the door is installed, a licensed inspector documents it on a wind mitigation form that you submit to your carrier.

The size of the credit varies by insurer, by policy and by what else on the home is protected. We cannot promise a specific number, and you should be skeptical of any contractor who does. What we can tell you is that the credit is real, it recurs every year, and for many homeowners it offsets a meaningful share of the door’s cost over time. Ask your agent what your carrier allows before you decide on a door.

The Installation Process

Assessment and measurement. We measure the opening, check the header and framing, and review your options on site. Free, no obligation.

Product selection. Material, insulation, windows, hardware and finish. We show you the NOA documentation for whatever you are considering.

Written quote, then permit. Garage door replacement is a permitted alteration throughout Miami-Dade and Broward. We handle the filing.

Installation and handover. Typically one day for a standard residential replacement. After county inspection we walk you through operation, maintenance and warranty, and leave you the NOA documentation for your insurance file.

Hurricane Door Questions

Does my garage door legally have to be hurricane rated in Miami-Dade?

If you are installing or replacing a garage door in Miami-Dade or Broward, yes. Both counties are High Velocity Hurricane Zones, and only products with a Miami-Dade Notice of Acceptance may be permitted there. An existing older door is generally not required to be replaced retroactively, but it cannot be re-permitted, and it remains the weakest point in the structure.

What is the difference between wind-load rated and impact rated?

A wind-load rating means the door can handle the pressure of high winds. An impact rating means it can also survive being struck by flying debris. Outside HVHZ zones a wind rating alone is sometimes sufficient. Inside Miami-Dade and Broward, you need both.

Can I reinforce my existing door instead of replacing it?

Bracing kits exist and are better than nothing, but they address wind pressure only, not impact, and they do not make a non-rated door code compliant. They also have to be installed before each storm and removed afterward. For a door already near the end of its life, replacement is usually the better value.

How long does installation take?

Most standard residential replacements are completed in a single day. Custom doors have a manufacturing lead time, typically several weeks, but the installation itself is still a one-day job.
