Hurricane-Resistant Home Construction in Florida

Load Paths, Roofs, Storm Shutters, and Beyond Code

Every new home in Florida is built to resist hurricanes, but “built to code” covers a wide range, and the details are where homes succeed or fail. A new build is your one chance to get those details right at the lowest cost. The connections hidden in the walls and the roof deck under the shingles can’t be easily upgraded later, and neither can the floor height. This guide explains how hurricane-resistant construction works, what the code requires, what storm shutter options you have, and where it can pay to go further. It’s part five of our series on building a house in Florida.

Short version: A hurricane-resistant home depends on a continuous load path: roof sheathing nailed to the framing, the framing strapped to the walls, and the walls anchored to the foundation. Florida’s code has required ring-shank nails for roof sheathing and a sealed roof deck since the 2020 edition, applying statewide outside Miami-Dade and Broward. Windows, doors, garage doors, and skylights must carry Florida product approval and be rated for your wind pressures. In wind-borne debris regions, they also need impact glass or approved storm shutters. Shutter options range from removable panels to accordion and roll-down systems. Any product sold as hurricane protection must be state-approved, and an HOA can’t deny protection that meets its adopted specifications. After Hurricane Ian, FEMA’s assessment team saw no wind-related structural damage to any home built under the Florida Building Code. It found elevation was the clearest predictor of flood performance. Florida insurers must offer discounts for wind-resistant features, so document them with a wind mitigation inspection.

What Hurricane Ian showed about modern code

FEMA sends a Mitigation Assessment Team after major hurricanes to study how buildings performed. After Ian hit near Fort Myers in 2022 as a high Category 4 storm, the team’s findings, as summarized by the International Code Council, were striking:

• Wind: the team “did not observe wind-related structural damage to any post-FBC homes,” meaning homes built under the Florida Building Code, which took effect in 2002.
• Flood: building elevation was a universal indicator of performance. Many older homes took 2 to 8 feet of water, while newer, elevated homes did far better.
• Claims: average NFIP building claims were $48,091 for buildings built after 2010, compared with $164,891 for buildings built before 1980.
• Roofs: roof coverings, both shingles and metal panels, were the most widely damaged component, especially at hips and ridges. Newer roof coverings generally performed better.

The takeaway for a new build: the structure is well protected by today’s code. The places to focus are the roof covering, the openings, and how high the house sits.

The continuous load path

Hurricane winds push on walls and pull up on the roof. A house survives when every piece is tied to the next, all the way down to the foundation. Engineers call this the continuous load path:

1. Roof covering to roof deck: shingles, metal, or tile fastened to the sheathing per the product approval
2. Roof deck to framing: sheathing nailed to trusses or rafters with the required nails and spacing
3. Roof framing to walls: metal clips or straps at every truss, rather than nails alone
4. Walls to foundation: anchor bolts, straps, or reinforced block tied into the footing

Florida’s wind mitigation form rates roof-to-wall connections from toe nails up through clips, single wraps, and double wraps. That’s a good reminder that some connections are stronger than others, and that insurers notice. Ask your builder which connectors the plans call for, and have your inspector check them before drywall. See independent inspections.

Walls: concrete block or wood frame?

The roof: where most hurricane damage starts

• Shape: hip roofs, which slope on all four sides, generally handle wind better than gable roofs with flat triangular ends. Roof geometry is one of the categories on Florida’s wind mitigation form. If you choose gables, make sure the gable ends are braced.
• Deck nailing: since the 2020 code, roof sheathing must be fastened with ring-shank nails, sized to the sheathing thickness.
• Sealed roof deck: also since 2020, statewide outside the High-Velocity Hurricane Zone, new roofs need a sealed roof deck. The options are a full self-adhered membrane, self-adhered tape over every deck seam plus underlayment, or two layers of underlayment. If the roof covering blows off, this layer helps keep rain out. Tile roofs follow the Florida high-wind tile installation manual.
• Roof covering: choose a product rated for your wind speed, installed exactly to its Florida approval. Hips and ridges are the weak spots, so installation quality there matters. The roofing article in this series compares metal, shingle, and tile.
• Soffits and vents: soffits, ridge vents, and other roof vents are common entry points for wind-driven rain. Ask for rated products and secure attachment.

Windows, doors, and garage doors

Openings matter because a broken window or a failed garage door lets wind inside. That pressure pushes up on the roof from below. Under Florida Statute 553.842, exterior doors, windows, skylights, shutters, and impact protective systems must carry Florida product approval, and each is rated for the design pressure it can handle.

• Design pressure: each window and door must meet the wind pressure calculated for its spot on your house. Corners see higher pressures.
• Impact protection: in wind-borne debris regions, openings need impact-rated products or approved shutters. Most of inland Central Florida isn’t in one, but coastal areas are. See Florida wind zones.
• Garage doors: often the largest opening on the house. Choose a wind-rated door, impact-rated where required, and make sure any glass panels in it are protected too.
• Entry doors and sliders: rated doors with proper anchoring, and sliding glass doors with protection planned from the start.

Storm shutters: your options

If you don’t choose impact glass, shutters are how you protect the openings. Even where they aren’t required, many inland owners install them for peace of mind and insurance credits. The main types:

Rules that apply to every shutter:

• State approval: under Section 553.842, a product can’t be marketed as hurricane, windstorm, or impact protection unless it’s approved. Get the Florida product approval number and confirm it covers your size and wind pressure.
• Installed to the approval: anchors, spacing, and the wall material all have to match the approval. On a new build, plan anchor locations into concrete or framing before the walls are finished.
• Plywood: the code allows precut wood structural panels only in limited cases on low-rise homes, with specific fastening prepared in advance. Ask your building department rather than counting on plywood.
• HOAs: under Florida Statute 720.3035, an HOA must adopt hurricane protection specifications. Those can cover color and style, but the HOA can’t deny an application that meets them.
• Insurance credit: on Florida’s wind mitigation form, the opening protection rating depends on the weakest protected glazed opening. Doors, garage doors, and skylights count too. One unprotected window can lower your credit, so protect everything.
• If you’re often away: seasonal residents and remote owners should favor systems that are permanent, quick to close, or motorized, or arrange for someone to deploy them. See the Florida snowbird guide.

Flood and storm surge: build up

Wind gets the headlines, but water does much of the damage. FEMA’s Ian findings point to elevation as the key. In A flood zones, Florida’s code requires the lowest floor at least 1 foot above the base flood elevation. Many owners go higher. Keep the AC condenser, water heater, and electrical panel above flood levels too. Foundation options and flood zone rules are covered in site prep and foundations, and coverage in Florida flood insurance.

Safe rooms

A safe room is a reinforced space built to protect people from extreme wind, designed to the ICC 500 standard and FEMA guidance. FEMA’s flood siting criteria are clear about storm surge:

• A safe room should not be located where storm surge or flooding could endanger people. It must be outside V zones and Coastal A zones, unless a local appeals board approves an exception.
• If one has to be in an A zone, FEMA says to elevate it to the highest of three levels: the local minimum, the base flood elevation plus 1 foot, or, for hurricane safe rooms, the 500-year flood elevation.
• A safe room must never be used in place of following an evacuation order.

In inland Central Florida, a safe room is mostly about extreme wind and tornadoes that can come with hurricanes. If you live in an evacuation zone, the plan is still to leave. See when to evacuate.

Going beyond code

• FORTIFIED: the Insurance Institute for Business and Home Safety (IBHS), a nonprofit research group, runs a voluntary FORTIFIED Home program with Roof, Silver, and Gold levels. Each step adds stronger roof, opening, and connection requirements, verified by a certified evaluator. Ask your builder whether they’ve built to it, and ask your insurer whether it earns a discount.
• Extra margin where it’s cheap: stronger roof-to-wall connectors, impact glass everywhere, a higher floor, and a wind-rated garage door all cost far less during construction than as retrofits.
• Staying livable after the storm: a generator connection, solar with a battery, and stored water make a strong house a usable one. See home backup generators and is solar worth it in Central Florida.

Getting insurance credit for what you built

Florida Statute 627.0629 requires insurers’ rate filings to include discounts or credits for features that reduce windstorm losses. These include roof strength and covering, roof-to-wall strength, wall-to-foundation strength, and opening protection. Features meeting the Florida Building Code’s minimums must be included, and since October 2023, insurers must post their mitigation discount information on their websites. The state’s uniform wind mitigation inspection form documents seven features: building code, roof covering, roof deck attachment, roof-to-wall attachment, roof geometry, secondary water resistance, and opening protection. Get a wind mitigation inspection when the house is done and send it to your insurer. See 4-point and wind mitigation inspections, My Safe Florida Home, and the hurricane preparedness guide.

Questions to ask your builder

• What design wind speed is the house built for, and is it in a wind-borne debris region?
• What roof-to-wall connectors are specified: clips, single wraps, or double wraps?
• Which sealed roof deck option will you use?
• What are the Florida product approval numbers and design pressures for the windows, doors, and garage door?
• What opening protection is included, and will every opening be covered?
• How high will the finished floor be above the base flood elevation?
• Have you built to the FORTIFIED standard, and what would it add?
