Wind mitigation inspections: the highest-ROI inspection in coastal home insurance

If you own a home in Florida, coastal Texas, Louisiana, Mississippi, Alabama, the Carolinas, or coastal Georgia, a wind mitigation inspection might be the highest-return $75-$150 you ever spend. Premium reductions of 20-50% are common. Some homeowners see their annual premium drop by $1,000-$3,000 from a single inspection.

What a wind mitigation inspection is

A licensed inspector evaluates your home’s hurricane-resistance features using a standardized form (in Florida, it’s the OIR-B1-1802; other states have similar). The inspector documents:

• Roof shape — hip roofs deflect wind better than gable roofs
• Roof-deck attachment — nail pattern, screw spacing, deck thickness
• Roof-to-wall connection — toe-nailed, clipped, single wraps, double wraps
• Roof covering — Class A vs other, compliance with Florida Building Code or similar
• Opening protection — impact windows, hurricane shutters, garage door bracing
• Secondary water resistance — sealed roof deck or peel-and-stick underlayment

Each feature is marked compliant or non-compliant. The carrier uses the form to apply specific premium credits.

Why the savings are so large

Hurricane premiums in coastal markets are high because insurers price in expected catastrophe losses. A home that’s properly hardened against hurricane wind reduces the carrier’s expected loss substantially. Carriers translate that risk reduction directly into premium credits — sometimes dramatic ones.

In Florida specifically, premium credits from a wind mitigation form can include:

• Hip roof shape: 15-25%
• Roof-deck nail pattern (8d nails, 6”/6”): 10-20%
• Roof-to-wall connection (double wrap): 15-30%
• Opening protection (hurricane impact windows or rated shutters): 10-25%
• Secondary water resistance (sealed roof deck): 5-15%

Stacked, these can produce 35-50%+ reductions from baseline rates. Not every home qualifies for every credit, but most homes get at least 2-3.

What to do

1. Get a Florida-licensed wind mitigation inspector (or equivalent in your state). Many home inspectors do these as add-on services. Cost is typically $75-$150.

2. Ask your carrier to apply the credits when the form is complete. Some carriers apply credits automatically; others require you to submit the form.

3. If you don’t have current credits, consider improvements that can earn them:

   • Re-nailing roof deck during a re-roof — relatively cheap, big credit
   • Installing hurricane shutters or impact windows — expensive upfront, but credits + safety justify it on older homes
   • Adding hurricane straps during major renovations
   • Sealed roof deck during re-roofing — small added cost, real credit

4. Re-inspect every 5 years or after any major roof or window work. Improvements that earn new credits should be documented.

When it’s not worth it

The math always works out positively if you live in a hurricane-exposed area. But some specific situations to consider:

• Newer homes (post-2002 Florida) were built to current hurricane code; credits may already be baked into your base rate, leaving less marginal savings.
• If you’re moving soon, the credits transfer with the home as a sales feature — still worth doing for marketability even if you don’t see the full annual savings.
• If your carrier is non-renewing you anyway, the wind mitigation form alone won’t keep them — but it makes your home more attractive to alternative carriers.

For homes more than 10 years old in coastal hurricane zones, the wind mitigation inspection is the single best money-saving move in home insurance. Get one.
