What do you need to know before hurricane season?

Hurricanes bring three distinct threats at once: wind, rain, and storm surge or inland flooding. Each one damages a home differently, so protecting against one doesn’t protect against the others. That’s why a hurricane-ready home checklist looks different from a general emergency plan, and why “hurricane prep” really means three overlapping projects: wind hardening, flood exposure, and evacuation readiness.

The Saffir-Simpson scale rates hurricanes 1 through 5 based on sustained wind speed. It’s a useful shorthand, but it has a real limitation worth understanding: the category tells you about wind, not about storm surge or rainfall, which are often the more damaging and deadlier parts of a hurricane. A Category 2 storm that stalls over your area and dumps two feet of rain can cause more damage than a fast-moving Category 4. Don’t let the category number alone determine how seriously you take a storm.

The single most important concept in hurricane-resistant construction is the continuous load path. It’s a method of building that uses metal connectors, hurricane straps and clips, to create a continuous structural chain that transfers wind loads from the roof, down through the walls, to the foundation. The goal is to hold the house together against the uplifting and lateral forces of hurricane-force winds, rather than letting any single weak connection fail first.

For homeowners, the practical takeaways from this concept are:

• Roof deck attachment matters more than people realize. A sealed roof deck, using a secondary water barrier under the shingles, can reduce water intrusion by as much as 95% even if the primary roof covering is damaged or lost. This is one of the highest-value upgrades available, and one of the least visible from the curb.
• Wind-rated roofing materials add real protection. High-wind rated shingles (Class H) combined with proper nailing patterns create a meaningfully stronger defense than standard materials and standard fastening.
• Windows and doors are a structural weak point, not just a comfort issue. If a window or door fails during a hurricane, it can cause a catastrophic increase in internal pressure that blows the roof off the house from the inside. Impact-resistant windows and doors are the strongest option in hurricane-prone areas. Storm shutters that meet the appropriate wind-load standards are a reasonable, lower-cost alternative if full replacement isn’t in the budget.
• Garage doors are commonly overlooked. An unbraced garage door is one of the largest openings on most homes and a frequent failure point.

In coastal areas, storm surge is often the most destructive part of a hurricane, not the wind. Homes in coastal flood zones typically need a raised foundation, piers or pilings, to elevate the structure above the base flood elevation defined by FEMA flood maps. Inland, away from surge risk, a reinforced slab-on-grade foundation is standard.

This is also where flood insurance becomes relevant even for a wind-focused disaster: standard homeowner’s insurance does not cover flooding, including storm surge. If you’re in a hurricane-prone coastal or near-coastal area, a separate flood policy, typically through the National Flood Insurance Program, is not optional protection. See Flood risk & prevention for the specifics.

Many insurance companies in hurricane-prone states offer real, meaningful discounts for homes with documented wind mitigation features. A wind mitigation inspection, performed by a qualified inspector, documents things like your roof shape, roof-to-wall connections, and window protection, and that documentation can lower your premium. Ask your insurer directly about wind mitigation credits before assuming your rate is fixed.

The FORTIFIED Home program, developed by the Insurance Institute for Business & Home Safety, is the recognized standard for hurricane-resistant construction, with a tiered approach (Roof, Silver, Gold) to retrofitting a home for resilience. See the FORTIFIED upgrade bridge for what each tier involves and what it costs.

Look up your evacuation zone now, before there’s any pressure to decide quickly. Evacuation zones are typically assigned by county or parish emergency management based on storm surge risk, and they’re usually available through a simple address lookup on your local emergency management website. Knowing your zone in advance means you’re not searching for it while also tracking a storm and packing a car.
