Living in Miami means living with hurricanes. Every year from June through November, homeowners across South Florida face the same critical question: is my home protected? The answer depends entirely on the hurricane protection system you choose, and the differences between your options are enormous in terms of cost, convenience, safety, and long-term value.
This guide breaks down every hurricane protection option available to Miami homeowners. We compare impact windows, impact doors, accordion shutters, roll-down shutters, hurricane panels, and plywood across every factor that matters: cost, protection level, code compliance, insurance savings, convenience, and property value. By the end, you will know exactly which option fits your home, your budget, and your lifestyle.
Why Hurricane Protection Is Mandatory in Miami
Miami-Dade County sits within the High-Velocity Hurricane Zone (HVHZ), the most stringent wind protection zone in the United States. After Hurricane Andrew devastated South Florida in 1992, destroying over 25,000 homes, the building codes that followed represent the hardest lessons learned from that catastrophe.
Under the Florida Building Code, every new construction and major renovation project in the HVHZ must include approved hurricane protection for all openings, meaning every window, door, sliding glass door, and garage door. There is no exception for small windows, bathroom windows, or any other opening. If wind and debris can penetrate it, it must be protected.
The science behind this requirement is straightforward. When a hurricane strikes, wind-borne debris, often pieces of roofing, tree limbs, gravel, and building materials, becomes airborne at speeds exceeding 100 miles per hour. If that debris penetrates a window or door, it creates an opening that allows wind pressure to enter the structure. Internal pressurization can blow off the roof from the inside, collapse walls, and cause total structural failure. A single unprotected window can be the difference between a home that survives and a home that is destroyed.
This is why the HVHZ testing standards are so demanding. Products must pass the large missile impact test, which fires a nine-pound two-by-four lumber at 34 miles per hour directly at the window or shutter, followed by thousands of cycles of positive and negative pressure that simulate sustained hurricane-force winds. Only products that pass both the impact and the cyclic pressure testing earn approval for use in the HVHZ.
Impact Windows and Doors: Always-On Protection
Impact windows and impact doors are the gold standard of hurricane protection. Unlike every other option on this list, impact-resistant windows and doors provide permanent, continuous protection without any preparation, deployment, or human action. When a hurricane watch is issued, there is nothing to do. Your home is already protected.
How Impact Windows Work
Impact windows use laminated glass consisting of two panes of tempered glass bonded to a tough interlayer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). When struck by debris, the glass may crack, but the interlayer holds the broken pieces in place, preventing penetration. The window remains intact as a barrier against wind and water. This is the same technology used in automobile windshields, scaled up and reinforced for hurricane-force conditions.
The frames are equally important. Impact window frames are constructed from heavy-duty aluminum, reinforced vinyl, or composite materials, and are anchored to the structure with heavy-gauge screws and structural brackets. The entire assembly, glass, frame, and anchoring system, is tested and certified as a unit.
Benefits Beyond Storm Protection
Impact windows deliver substantial value beyond hurricane season. The laminated glass construction provides year-round benefits that no shutter system can match:
Property Value +5 to 10%
Impact windows are one of the highest-ROI home improvements in South Florida. Buyers pay a premium for homes that are already protected, and appraisers factor impact windows into valuations.
Energy Savings 15-25% (with Low-E)
Impact windows with Low-E coatings and insulating interlayers dramatically reduce heat transfer, lowering air conditioning costs year-round in Miami's tropical climate.
Noise Reduction Up to 50%
Laminated glass is one of the most effective sound barriers available for residential use. Road noise, aircraft, construction, and neighborhood sounds are significantly dampened.
99% UV Protection
The interlayer blocks nearly all ultraviolet radiation, preventing fading and deterioration of furniture, flooring, artwork, and fabrics.
Enhanced Security
Impact glass is extremely difficult to break through, providing burglar resistance equivalent to or better than a security bar system.
Insurance Discounts 25-45%
Impact windows qualify for the highest level of insurance discounts available for opening protection, often reducing wind premiums by 25 to 45 percent.
Cost of Impact Windows
Impact windows are the most significant upfront investment, typically ranging from $40 to $75 per square foot installed, depending on the window type, size, and frame material. For a typical Miami home with 15 to 20 openings, a complete installation generally falls between $15,000 and $40,000. For a detailed breakdown, see our cost guide. While the initial cost is higher than shutters, the combination of insurance savings, energy savings, and increased home value means impact windows often pay for themselves within 7 to 12 years.
Accordion Shutters: Permanent and Deployable
Accordion shutters are permanently mounted beside each window or door opening and fold out horizontally on a track when a storm approaches. They are the most popular shutter type in South Florida and offer a good balance of protection, cost, and convenience. When not in use, they stack neatly to the sides of the opening.
How Accordion Shutters Work
Accordion shutters consist of interlocking aluminum or steel blades that ride on a top and bottom track. To deploy them, you pull the shutter panels from one or both sides across the opening and lock them in the center with a latch or key lock. The entire process takes approximately 10 to 30 minutes for a typical home, depending on the number of openings and whether any shutters are hard to reach.
Because they are permanently attached, there is no storage requirement. You do not need to haul panels out of a garage or find space for bulky equipment. Accordion shutters are always right where you need them.
Pros and Cons
Advantages: Accordion shutters cost approximately $15 to $20 per square foot installed, making them the most cost-effective permanently mounted option. They deploy quickly without tools. They meet Florida Building Code requirements for the HVHZ. They qualify for insurance discounts. They also provide security when locked.
Disadvantages: Accordion shutters are visible on your home at all times, even when folded. Some homeowners find them unsightly. They block all natural light and visibility when deployed, turning your home completely dark. They require someone to be physically present to deploy them, which is a serious concern if you are traveling when a storm approaches. They do nothing for energy efficiency, noise reduction, or UV protection. They can corrode in the salt air of coastal Miami without regular maintenance and lubrication.

Roll-Down Shutters: The Premium Shutter Option
Roll-down shutters, also called rolling shutters, are housed in a box mounted above the window or door opening. They roll down vertically along side tracks to cover the opening. Available in both manual crank and motorized versions, roll-down shutters are the strongest and most convenient type of shutter, and also the most expensive.
How Roll-Down Shutters Work
The shutter consists of interlocking extruded aluminum slats that coil around a barrel inside a housing box. Manual versions use a hand crank or strap to lower and raise the shutter. Motorized versions operate at the push of a button and can often be integrated with smart home systems or operated remotely. Deployment takes just minutes for a motorized whole-home system.
Pros and Cons
Advantages: Roll-down shutters provide the highest impact resistance of any shutter type. The motorized option allows remote deployment, meaning you can protect your home from anywhere. They are more aesthetically streamlined than accordion shutters when retracted. They meet all Florida Building Code requirements and qualify for top-tier insurance discounts. They also provide excellent security and can deter break-ins.
Disadvantages: Roll-down shutters are the most expensive shutter option, typically costing $25 to $45 per square foot installed, with motorized versions at the higher end. The housing box above the window is visible and changes the exterior appearance of the home. Like all shutters, they block light and visibility when deployed. Motorized versions require electrical connections and can fail during power outages without battery backup. Maintenance costs are higher because of the mechanical components.
Hurricane Panels: Budget-Friendly Basic Protection
Hurricane panels are removable sheets of corrugated aluminum or steel that bolt onto permanent tracks or clips installed around each window and door opening. They are the cheapest form of code-compliant hurricane protection and remain a common choice for budget-conscious homeowners.
How Hurricane Panels Work
Permanent header and sill tracks are installed above and below each opening. When a storm approaches, you lift each panel into the top track, swing the bottom into the lower track, and secure it with wing nuts, barrel bolts, or clips. The panels overlap each other to create a continuous barrier. Clear polycarbonate panels are also available and allow some light transmission, though they cost more than metal options.
Pros and Cons
Advantages: Hurricane panels are the most affordable code-compliant option, costing approximately $7 to $15 per square foot. They meet Florida Building Code requirements for the HVHZ when properly installed with approved hardware. They qualify for insurance discounts. When removed, they are invisible and do not alter the appearance of your home.
Disadvantages: Hurricane panels take 4 to 8 hours to install on a typical home, usually requiring two people and a ladder. They are heavy and awkward to handle, especially on second-story windows. They require significant storage space in your garage or shed when not in use. The installation process is physically demanding and can be dangerous on ladders in pre-storm conditions. You must be home to install them, and with South Florida evacuation timelines, you may not have enough advance warning. Panels can also be dented, bent, or lost over time.
Plywood: The Last Resort
Plywood is the fallback option that many homeowners consider because of its low cost and availability at any hardware store. However, it is essential to understand that plywood does not meet the Florida Building Code for hurricane protection in the HVHZ. Using plywood is choosing to be non-compliant with the code, which has serious implications for insurance, safety, and liability.
Why Plywood Fails as Hurricane Protection
Standard plywood has never passed the HVHZ large missile impact test. A nine-pound two-by-four traveling at 34 miles per hour will penetrate most plywood thicknesses. Even 5/8-inch CDX plywood, the thickness most commonly recommended, can fail under the debris impact and pressure cycling that approved products must withstand.
Plywood also takes 4 to 8 hours to install on a typical home and requires pre-drilling, lag bolts, and a ladder. Sheets must be custom-cut for each opening. In pre-storm conditions with rain and wind, this installation process becomes genuinely dangerous. And if you are away from home when a storm threatens, plywood offers no protection at all.
Insurance and Financial Consequences
Because plywood does not meet the Florida Building Code, it does not qualify for any insurance discount on wind premiums. Your wind mitigation inspection will classify your openings as unprotected. You will pay the highest possible insurance rates, and in the event of storm damage, your claim may be reduced because your home did not have approved protection.

Which Option Is Right for You?
Choosing the right hurricane protection depends on three factors: your budget, your lifestyle, and the type of property you own. There is no single answer that works for everyone, but the following guidelines will help you make the right decision.
The True Cost of NOT Having Hurricane Protection
The cost of installing hurricane protection is real and significant. But the cost of not having it is far greater. A single window failure during a Category 3 or higher hurricane can result in catastrophic interior damage with average claims exceeding $50,000.
Hurricane Damage Statistics
A single window failure during a Category 3 or higher hurricane can result in catastrophic interior damage. When wind enters through a broken window, the internal pressure can blow out other windows, lift the roof, and destroy walls. Average insurance claims for hurricane wind damage in Florida exceed $50,000, and total losses for homes with structural failure frequently exceed $150,000 to $300,000. In many cases, the damage exceeds the home's value and triggers a total loss.
Even a near-miss or Category 1 hurricane can cause $10,000 to $30,000 in water damage if wind-driven rain enters through unprotected openings. Water intrusion destroys drywall, flooring, insulation, electrical systems, and personal belongings. Mold remediation alone can cost $5,000 to $30,000.
Insurance Implications
Without approved hurricane protection, you will pay the highest wind insurance premiums available. In Miami-Dade County, the difference between having impact windows and having no protection can be $1,500 to $3,000 per year in additional premiums. Over 10 years, that is $15,000 to $30,000 in insurance costs alone, often enough to pay for a complete impact window installation.
Additionally, if you file a claim after a hurricane and your home did not have code-compliant protection, your insurer may apply depreciation, deny portions of the claim, or argue that the damage was preventable. An unprotected home is a financial liability on every level.
Florida Building Code Requirements for Hurricane Protection
The Florida Building Code sets specific requirements for hurricane protection based on your location within the state. Miami-Dade County and Broward County are designated as the High-Velocity Hurricane Zone (HVHZ), which has the most stringent requirements in the country.
Permit Requirements
All hurricane protection installations in Miami-Dade County require a building permit. This applies to impact windows, impact doors, all types of shutters, and even permanent track installations for hurricane panels. The permit process requires product approval documentation, engineering calculations for wind loads, and a final inspection after installation. Working without a permit can result in fines, and unpermitted work can create significant problems when selling your home.
Insurance Discounts by Protection Type
Florida law requires insurance companies to offer discounts for hurricane mitigation features, including opening protection. The size of your discount depends on the type and extent of protection you have, as determined by a wind mitigation inspection.
Opening Protection Ratings
The wind mitigation inspection form classifies your opening protection into one of four categories:
Maximizing Your Discount
To qualify for the highest insurance discount, every single opening in your home must be protected with an approved product. This includes windows, entry doors, sliding glass doors, French doors, garage doors, and any other opening in the building envelope. Missing even one small window will drop you from Rating A and significantly reduce your discount.
Impact windows and doors provide a significant advantage here because they protect every opening simultaneously and permanently. With shutters, you must deploy every single shutter before every storm. If one shutter fails, sticks, or is overlooked, your home has an unprotected opening during the worst possible moment.
