How to Get a Windstorm Certification for Your Home
A licensed contractor or engineer inspects the house against your state's wind mitigation standards and files the report with your insurer.

The inspection checks features that resist wind damage, things like roof shape, roof-to-wall connections, shutters and the age of the roof covering. Each feature gets scored against your state's wind mitigation form. Insurers use that score to lower the wind or hurricane part of your premium, since a roof less likely to fail is less likely to produce a big claim. Your agent can tell you which features matter most for your house and whether the inspection fee is worth the expected savings.
A wind mitigation credit only changes what you pay, not what the house is worth, which is why it's worth checking against more than one insurer. Some weigh roof shape and roof-to-wall connections more heavily than others, so the same certification can lower one quote a little and another a lot. Comparing now shows which company actually rewards the work already done on the house.
What the inspection actually checks
The inspector works through a form, usually the one your state's insurance department publishes, and scores specific parts of the house rather than giving a general impression of how sturdy it is. Roof shape matters a lot. A hip roof, which slopes on all four sides, handles wind better than a gable roof with flat vertical ends, and it usually scores higher. Roof covering age matters too, since a newer roof installed to current code gets more credit than an older one even if both look fine from the ground.
The roof-to-wall connection is often the biggest factor. Inspectors look for metal clips or straps tying the roof structure to the walls, called hurricane clips or straps, versus just nails, which pull loose more easily under wind pressure. They also check whether windows and doors have shutters or impact-rated glass, since a broken window lets wind inside the house and that pressure can lift the roof from underneath. The garage door gets a look too, because a standard door can fail under wind load and once it does, the whole house is exposed.
Most inspections take one to two hours and run somewhere in the low hundreds of dollars, paid by the homeowner, though this varies by inspector and region. The certification is typically good for several years before it needs to be redone, and the exact term is set by your state. If the roof gets replaced or you add shutters after the original inspection, a new report showing the upgrade is what gets the updated discount applied, not the old one.
Not every house scores well enough to make the inspection worth the cost. A house with an older roof, a gable end and no shutters may not qualify for much of a credit, and the inspector will tell you that before you pay for the full report in some cases. Asking a contractor or your agent which features your house is likely to score well on, before booking the inspection, saves paying for a report that comes back with little to show for it.
Where to find an inspector and what happens to the report
The inspector has to be qualified under your state's rules, usually a licensed contractor, building inspector or engineer who's trained to fill out the wind mitigation form correctly. Your state's insurance department website often keeps a list, and some insurers maintain their own list of inspectors whose reports they already trust. Picking someone from either list avoids a report that gets sent back for missing information or filled out in a way your insurer won't accept.
Once the inspection is done, the report goes to your insurer, not to a general state registry. You'll usually get a copy too, and it's worth keeping one for your own records since you may need to show it again if you switch insurers later. Some companies apply the credit automatically once the report is on file, others ask you to request it be applied to your policy, so it's worth asking your agent how your insurer handles it.
If you're switching insurers, bring the report with you. A current wind mitigation inspection is tied to the house, not the policy, so a new insurer can use the same report to calculate the same credit, as long as it's still within the valid period your state sets. This is part of why comparing insurers is worth doing even after you've already gotten the discount applied once. The same piece of paper can be worth different amounts depending on who's pricing it.
A few states also tie wind mitigation credits to building code updates, meaning a house built or re-roofed after a certain year may already qualify for some credit without a separate inspection, since the permit records show the construction met current standards. Your agent can tell you whether your state works this way and whether your house's build year already counts for something before you pay for an inspection at all.
Before you book an inspection
Check your roof's age and shape, and whether you have hurricane clips or shutters. Those are the features insurers score. Then compare quotes to see which company gives your house the most credit for them.
