Protecting a home from a hurricane requires two separate plans: one for wind and one for flooding. Wind measures keep the roof, windows, garage door and structural connections from failing. Flood measures address the property’s elevation, enclosed areas and insurance exposure. Begin with local hazard maps and a qualified assessment of your home, then combine durable retrofits with seasonal preparation and a current coverage check.
Start with the hazards that actually affect your property
Hurricanes can damage a house through several different paths: extreme wind, wind-borne debris, wind-driven rain, storm surge, rainfall flooding and rising water around the foundation. A measure designed for one path may do little for another. For example, a shutter can protect a window from debris, but it does not stop storm surge from entering a low-lying enclosure. Conversely, a flood opening designed to equalize water pressure is not a substitute for protecting the roof.
Check wind exposure and local requirements
Use your local building department and emergency-management office to identify applicable wind loads, required opening protection and permit rules. FEMA’s wind-retrofit guidance treats the roof, windows, doors, garage doors and structural connections as related parts of one system. Coastal exposure, nearby terrain, the age of the building and previous alterations can all change the appropriate design.
Do not assume that a product marketed for hurricanes is automatically suitable. Opening dimensions, attachment surfaces, wind exposure, approval ratings and installation details must match the specific house and the rules in its jurisdiction.

Check flood, rainfall and storm-surge exposure
Review current flood maps and local storm-surge and rainfall-flood information. Ask the floodplain official how the property’s base flood elevation, lowest floor, foundation type and enclosed areas affect permitted work. Flood risk can exist outside a mapped high-risk zone, and a house that has never flooded may still be exposed to surge or intense rainfall.
Record the elevation and use of each lower-level space. A garage, crawlspace, storage area or room below the base flood elevation may be treated differently from occupied living space. These facts determine whether a flood-opening approach is applicable, whether other mitigation is required and what permits are needed.
Have the home assessed before choosing a retrofit
Gather the construction year, roof age, roof shape, framing type, foundation type, window and door dimensions, garage-door design and any previous repairs. A qualified roofing or wind-retrofit professional can inspect concealed connections and identify vulnerabilities that are not visible from the ground. Floodplain officials, building officials and design professionals can determine whether a proposed change complies with local floodplain rules.

Protect the roof first
The roof is the home’s first large wind-exposed surface. A failure at the covering or deck can allow rain into the building and create forces that lead to larger structural damage. IBHS recommends a professional roof inspection and repair of identified weaknesses. FEMA’s wind-retrofit guide also addresses roof attachment and connections between the roof, walls and foundation.
Inspect and repair existing vulnerabilities
- Have a qualified professional inspect the roof covering, deck attachment, edges, flashing, penetrations and connection points.
- Repair deteriorated materials and correct installation defects before hurricane season rather than waiting for a forecast.
- Ask whether the roof-to-wall connections are adequate for the home’s location, age and construction. This question may require access to the attic or concealed framing.
- Replace or reinforce components only with methods appropriate to the existing structure and local code.
A roof inspection is not the same as a visual check from a ladder. Structural connections and deck nails may be hidden, and an apparently sound roof can still have an inadequate attachment pattern.

Use durable reroofing improvements when the roof is replaced
IBHS describes these features for a FORTIFIED Roof: ring-shank nails installed in a tighter roof-deck nailing pattern, a sealed roof deck that limits water intrusion if the roof covering is damaged, and secured roof edges. These features improve resistance and reduce the chance that a covering failure becomes extensive water damage, but they do not make a home hurricane-proof.
Discuss the roof assembly as a whole with the contractor. The correct fastening pattern, edge treatment, underlayment, deck condition and connection details depend on the roof design and local requirements. Keep invoices, product documentation and inspection records; they can help demonstrate what work was performed and support future maintenance.

“Wind entering the home through an opening or broken window, can create strong upward pressure on the roof, much like air can build up in a balloon.”
IBHS President and CEO Roy Wright made that statement in an October 8, 2018 release. It explains why opening protection is part of roof protection: a broken window or failed door can pressurize the interior while wind continues to flow over the outside of the roof.
Protect windows, doors and the garage
Windows and other openings are vulnerable to wind-borne debris and pressure changes. FEMA identifies storm shutters as a common opening-protection option. The right system depends on the opening, the wall around it, the design wind speed and local approval requirements.

Choose and install shutters for the specific opening
- Measure every window, glazed door and other opening that needs protection; dimensions are rarely identical throughout a house.
- Identify the substrate where fasteners will attach. Masonry, wood framing and previously repaired walls require different attachment details.
- Confirm that the shutter or panel system is approved for the local wind and debris requirements and that its installation instructions match the building.
- Install permanent tracks, anchors or brackets before a storm threatens. Test that each panel, shutter or accordion system can be deployed without improvised hardware.
- Store removable components where they remain dry, accessible and clearly labeled for each opening. Replace damaged parts before the next season.
Storm shutters are not a universal product recommendation. A system that fits one window may be unsuitable for another, and a poorly anchored shutter can fail with the opening it was intended to protect. Ask the building department whether permits or inspections are required.
Recommended Free Tools
Do not overlook the garage door
A wide garage door presents a large flexible opening. FEMA and IBHS both identify garage doors among the vulnerabilities to assess. Check the door, tracks, rollers, hinges, anchorage and the wall framing around the opening. If the door is not rated for the local wind conditions, a qualified contractor can determine whether reinforcement or replacement is feasible. Do not rely on a temporary brace unless it is an approved system installed as directed.
Include entry doors and other penetrations
Inspect exterior doors, sliding doors, skylights, vents and service penetrations. Verify that locks engage the frame and that the frame is securely attached to the surrounding wall. Protect glazed doors and other large openings with a system designed for them; a window panel should not be assumed to protect a door.
Build a continuous roof-to-foundation load path
IBHS describes a continuous load path as a connected route that carries wind forces from the roof through the walls and into the foundation and ground. If one connection is weak, the force can concentrate at that point and contribute to progressive failure. FEMA’s guide discusses higher retrofit levels that address connections as well as openings.
What a load-path assessment examines
- Roof-to-wall connections, including whether existing connectors are present and properly fastened.
- Wall-to-floor and floor-to-foundation connections that transfer uplift and lateral forces.
- Shear walls, bracing and the ability of the structure to resist racking.
- Garage and large-opening framing, where interruptions can reduce the strength of a wall line.
- Foundation condition and the connection between the lowest structural elements and the ground.
These are structural retrofit questions, not generic do-it-yourself tasks. A licensed engineer, architect or qualified wind-retrofit contractor should evaluate the existing construction and specify connectors, fasteners and access requirements. Adding a connector without confirming the strength of the wood, masonry or foundation receiving it can create a false sense of security.

Use seasonal preparation as a supplement, not a substitute
Durable work can take weeks or months, so separate it from actions taken when a storm is approaching. IBHS recommends preparing in stages, with larger projects completed before the season and short-term tasks handled as a storm develops.
Before hurricane season
- Schedule the roof inspection and complete repairs.
- Test shutters and permanently installed opening-protection hardware.
- Inspect the garage door and exterior doors.
- Trim or remove loose items that could become debris, following local guidance for trees and utilities.
- Document the house with photographs and keep contractor records, warranties and insurance information in a secure location.
- Confirm where removable shutters, panels and tools are stored and who will install them.
When a storm is forecast
- Monitor official emergency-management instructions and evacuation orders; structural protection does not make a property safe to occupy in every storm.
- Deploy shutters and other approved opening protection according to the manufacturer’s instructions. Do not wait until winds make exterior work dangerous.
- Secure or bring inside loose outdoor objects and complete the roof and garage-door checks that can be done safely.
- Close interior doors as an additional precaution, as described in IBHS seasonal advice. This does not replace exterior opening protection.
- Move valuables and critical documents above expected water levels when flooding is possible, without delaying evacuation.
Flood protection starts with elevation and building type
Flood mitigation cannot be selected from a wind checklist. The appropriate method depends on the expected depth and velocity of water, the building’s elevation, its foundation and whether lower areas are enclosed. Local floodplain rules may restrict the materials, uses and alterations allowed below the base flood elevation.
Understand wet floodproofing’s limited purpose
FEMA’s 2025 homeowner guide discusses wet floodproofing for applicable enclosed areas below the base flood elevation. The approach allows floodwater to enter and leave automatically so that water pressure is reduced rather than forcing walls to resist unequal pressure. The guide’s example requirements include openings in at least two different walls and a minimum net opening area; covers or screens cannot block the required flow.
Those technical conditions apply only within the guide’s stated scope and do not authorize converting a lower enclosure into living space. The openings, placement, size, protection against blockage and any flood-resistant materials must be designed and approved under local rules. A floodplain official or qualified design professional should review the proposal before construction.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsFlood openings are not flood barriers
A compliant flood opening equalizes pressure; it does not keep water out. A barrier or dry-floodproofing approach attempts to exclude water and may be restricted or unsuitable for a particular residential structure. Choosing between approaches requires the property’s elevation, construction, flood exposure and local regulations. Installing an opening where a barrier is needed, or sealing an area that must be allowed to flow through, can increase damage and violate floodplain requirements.

Plan for storm surge without relying on one product
Storm surge can move water, debris and floating objects across a property. The safest response may involve evacuation, elevation or relocation decisions rather than a single wall, panel or seal. Ask local officials how surge depth, velocity and duration affect the site. Keep electrical equipment, fuel-burning appliances and other vulnerable systems above expected flood levels only when the work is designed and permitted for the building.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Flood insurance is a separate decision
FEMA’s homeowner checklist says standard homeowners policies generally do not cover flood damage. That checklist is older, so do not assume its wording reflects every current policy or market. Read the declarations and exclusions for your own policy and verify current flood-insurance terms, waiting periods, limits and availability through official National Flood Insurance Program information or a licensed insurance professional.
Insurance does not prevent damage, and physical mitigation does not guarantee coverage for every loss. Keep an inventory of the home’s contents, photographs, receipts and policy documents in a location that remains accessible after an evacuation. Ask how the policy treats below-grade areas, temporary relocation, debris removal and replacement value before a storm occurs.

Use evidence without treating it as a guarantee
IBHS announced in 2026 that a study of more than 40,000 homes affected by Hurricane Sally found homes with the organization’s stronger construction approach were 70% less likely to need an insurance claim. The announcement does not provide the study methodology in the available passage, so treat the figure as a reported study finding, not a universal causal estimate or a promise that any individual home will avoid damage.
The practical implication is to prioritize connected, well-maintained systems: a sound roof, protected openings and reliable load transfer. Each component still needs to be matched to the home and local hazard.
A decision sequence for homeowners
- Map the exposure. Identify wind, rainfall-flood and storm-surge hazards, then confirm the property’s flood zone and base flood elevation with local officials.
- Document the construction. Record roof, openings, garage, foundation, lower enclosures and previous alterations.
- Fix the roof. Complete inspection and repairs; if reroofing, discuss sealed-deck, stronger deck attachment and secured-edge details.
- Secure openings. Select and install opening-specific shutters or other approved protection, including a garage-door solution.
- Evaluate the load path. Obtain professional advice on roof-to-foundation connections before adding structural hardware.
- Choose flood measures narrowly. Determine whether compliant wet-floodproofing openings apply; do not confuse them with barriers or use them to justify occupied space below the required elevation.
- Check financial protection. Review the current homeowners policy and obtain verified flood-insurance information if appropriate.
- Practice the storm plan. Know who deploys shutters, where components are stored, which items move indoors and when evacuation takes precedence over property preparation.
The correct combination is property-specific. Local maps, elevation data, construction details, professional evaluation and current code requirements determine which wind retrofits and flood measures are lawful and worthwhile.
