Roof tie-downs, storm shutters, garage door reinforcement, securing outdoor items, and a 72-hour pre-landfall preparation timeline.
Evacuation saves lives in storm surge zones — but for people sheltering in place in sturdy structures outside surge zones, the condition of their home determines their safety. A well-prepared home can withstand a direct hit from a moderate hurricane with manageable damage. An unprepared home may suffer catastrophic failure that kills its occupants.
Home preparation for a hurricane or cyclone has two components: the year-round structural improvements that cannot be done in the hours before a storm, and the immediate pre-storm actions in the 72 hours before landfall. Both matter.
The roof is the most vulnerable component of a residential building in a hurricane. Wind pressure both pushes down on the roof from above and lifts it upward from below. At high wind speeds, the net effect is often upward — the roof acts like a wing. Once the roof is removed, the walls lose their structural bracing and typically collapse.
Hurricane straps (also called rafter ties or H-clips): Metal connectors that mechanically connect the roof rafters or trusses to the wall top plate and wall framing. Without them, the roof is held on primarily by nails — insufficient in hurricane-force winds.
In many pre-1992 US homes in hurricane-prone areas, hurricane straps were not required and may not be present. A roofer or building contractor can inspect your attic and confirm whether straps are present and correctly installed.
If hurricane straps are not present, retrofitting is possible — a contractor can install straps from the attic space. This is one of the highest-value structural investments for hurricane-prone homes.
Roof deck fastening: The plywood or OSB roof deck (the structural sheathing between the roof framing and the roof covering) is attached with nails. In older homes, the nail spacing and nail type may not meet current wind standards. Improving roof deck fastening (using ring-shank nails or screws at closer spacing) significantly improves resistance to roof covering loss.
The garage door is often the largest opening in a home and one of the most vulnerable elements. In many residential garage doors, the panels are held in their tracks by relatively light hardware. Under hurricane wind pressure, garage doors can bow, flex, and fail — and once the garage door fails, wind pressure enters the structure, pressurising it from inside and dramatically increasing the likelihood of roof loss.
Retrofit options:
After Hurricane Andrew (1992), Florida updated its building codes to require garage doors tested to specific wind pressure standards. Homes built to post-1992 Florida building code in many areas have significantly more resistant garage doors. Confirm your door's rating if you are not certain.
Storm shutters: The most reliable permanent solution. Types include:
Storm shutters that are rated for hurricane conditions have been tested to withstand wind-borne debris impact, which is the primary window failure mechanism in hurricanes.
Plywood boarding: If permanent shutters are not installed, 12mm (half-inch) plywood can be cut, pre-drilled, and stored for rapid installation. Pre-cut plywood panels with pre-drilled holes and marked positions (label each panel with its window) dramatically reduce installation time. Install plywood with screws into the wall framing, not just the window frame or stucco/cladding.
Impact-resistant glass: A structural window upgrade — glass that meets Florida Product Approval or Miami-Dade impact standards does not require covering. This is the most convenient long-term solution but the highest upfront cost.
Sliding glass doors: These are particularly vulnerable due to their size and the relatively poor track sealing. Ensure bracing bars are installed in the interior track to prevent door panel removal. Panel protectors (storm panels) are available.
Outdoors — secure or remove all potential projectiles: Any unsecured outdoor object becomes a dangerous projectile at hurricane-force wind speeds. Items that appear harmless in calm conditions — a plastic lawn chair, a ceramic pot, a garden hose reel — can become lethal at 150+ km/h.
Items to secure or bring inside:
Tree and vegetation management (pre-season, not at 72 hours): Overhanging branches near the roof, window, or power service entry are hazards. Proper trimming of trees before hurricane season — by a qualified arborist using correct technique — reduces the risk of branches becoming projectiles or entering the building.
Note: Do not attempt to trim trees 72 hours before a storm — this is a year-round maintenance task. At 72 hours, your focus is property securing, not major work.
Roof inspection:
Walk around and look at your roof from the ground. Identify:
A roof with existing damage will fail sooner and more catastrophically in hurricane conditions. If significant damage is identified, contact a roofing contractor — though at 48 hours this may not be feasible before the storm.
Safe room considerations:
If your home does not have a purpose-built safe room, identify the interior room that offers the most protection:
Stock the safe room with: water (one full bathtub plus bottled), flashlights, first aid kit, phone charger, weather radio, spare clothing.
Water storage:
Fill your bathtub completely. This water is for flushing toilets and possibly drinking (purify if needed) if municipal water supply fails. Commercial bathtub water storage bags (WaterBOB and similar products) hold more and prevent contamination. One full bathtub = approximately 300 litres.
Fill all available containers with drinking water — a hurricane can disrupt water service for days to weeks.
Generator pre-positioning:
If you own a generator:
Food preparation:
Ice:
Purchase bags of ice and store in coolers. Prioritise medication that requires refrigeration (insulin, certain cardiac medications) — ensure an adequate cold storage solution if power loss is likely.
Final check of supplies:
| Supply Item | Minimum Recommended |
|---|---|
| Drinking water | 4 litres per person per day × 7 days |
| Non-perishable food | 3-day minimum, 7-day preferred |
| Prescription medications | 30-day supply |
| Phone chargers (fully charged) | One per household member |
| Battery/hand-crank weather radio | Charged or batteries confirmed |
| Cash (small denominations) | ATMs may not work for days |
| First aid kit | Checked and complete |
| Flashlights and spare batteries | Confirmed working |
| Generator and fuel | If owned — tested and fuelled |
⚠️ If an evacuation order is issued for your zone at any point in the 72 hours before landfall — leave immediately. No home is worth your life in a storm surge zone. The time to leave is when the order is issued, not when conditions begin to deteriorate.
| Situation | Action |
|---|---|
| Hurricane season starts (June 1, Atlantic) | Inspect roof; trim trees; check storm shutters; test generator |
| Hurricane Watch issued | Begin securing outdoor items; review evacuation plan |
| Hurricane Warning issued (72 hrs) | Secure all outdoor items; complete pre-storm checklist |
| 48 hours before landfall | Install shutters or plywood; fill water storage; check food supply |
| 24 hours before landfall | Fill fuel (car and generator); prepare safe room; charge all devices |
| Garage door not rated for hurricane | Install bracing kit before storm season; replace if old |
| No storm shutters available | Pre-cut plywood panels; store with pre-drilled holes and labelling |
| Evacuation order for your zone | Leave immediately — do not wait |
| Generator available | Position outside; test; ensure fuel supply; pre-run extension cords |
| After storm passes | Do not go outside until all-clear confirmed — eye passage may cause false lull |
