Most of what's driving South Carolina home insurance premiums up is out of your hands — reinsurance costs, statewide storm losses, carriers pulling back from the coast. I break all of that down in Why Home Insurance Is More Expensive in South Carolina in 2026.
But there's one powerful lever you can pull — and hardly any agent talks about it. South Carolina law requires insurers to give you a discount for making your home more wind-resistant. Do the work, document it, and your premium comes down — sometimes by a lot. Better still, the state has a grant program that can help pay for the biggest upgrade.
I'm Ben Mauldin, an independent agent in Lexington. Here's how wind mitigation credits work, what earns them, and how to stack them with a state grant.
What wind mitigation credits actually are
Wind mitigation credits are mandatory premium discounts that South Carolina requires insurers to offer when your home has features that help it stand up to hurricane-force wind. This isn't a promotion a carrier can choose to skip — it's built into state law.
How big is the discount? The combined credits can reach up to 48% of the wind portion of your premium for a fully mitigated home, and the average homeowner who qualifies saves around 14%. On a coastal policy, that's real money every single year — for improvements that also make your home safer.
The catch is that the credit isn't automatic. You have to prove your home has the qualifying features, and that proof comes from a wind mitigation inspection.
What actually earns the credit
A wind mitigation inspection looks at the specific features engineers know keep a roof on a house during a hurricane. The big ones:
- Roof shape. A hip roof (sloped on all sides) sheds wind far better than a gable roof and earns a strong credit.
- Roof deck attachment. How the plywood decking is fastened — nail type and spacing — matters enormously.
- Roof-to-wall connections. Hurricane clips or straps that tie the roof to the walls (versus just nails) are one of the most valuable credits.
- Roof covering. Shingles or covering rated to current building-code wind standards.
- Secondary water barrier. A sealed layer under the roof covering that keeps water out even if shingles blow off.
- Opening protection. Impact-resistant windows and doors, or storm shutters.
- Gable-end and garage-door bracing. Reinforcement at the home's most vulnerable failure points.
You don't need all of them to save money. Even a few of these features can move your premium — which is exactly why an inspection is worth doing.
The inspection and the form that unlocks the discount
Here's the mechanism. A qualified inspector evaluates your home and documents the features on a standardized wind mitigation report (in South Carolina, the Uniform Mitigation Verification Inspection Form, OIR-B1-1802). That report is what your carrier uses to apply the credits.
The process is simple:
- Get a wind mitigation inspection.
- Send me (or your agent) the completed report.
- The qualifying credits get applied to your policy.
An inspection is a modest one-time cost, and if it uncovers even a couple of credits on a coastal home, it often pays for itself in the first year — and every year after.
What to Do If you own a coastal or near-coastal home and have never had a wind mitigation inspection, that's very likely money sitting on the table. Get the inspection, send me the OIR-B1-1802 report, and I'll make sure every credit you've earned is actually applied to your policy. Many homeowners are already sitting on features they're not being credited for.
The gold standard: a FORTIFIED roof
If you're already facing a roof replacement — or you want the maximum credit — the upgrade to aim for is an IBHS FORTIFIED roof. FORTIFIED is a nationally recognized construction standard built specifically to keep roofs on and water out during severe storms. It typically earns among the largest insurance credits available, and in a tightening coastal market it can also make your home easier to insure in the first place.
It costs more than a standard roof — but that's where the state steps in.
The state may help pay: SC Safe Home grants
South Carolina runs the SC Safe Home Mitigation Grant Program through the Department of Insurance, and it can help cover the cost of strengthening your roof:
- Up to $7,500 (non-matching) or $6,000 (matching) for work meeting the full IBHS FORTIFIED Roof standard.
- Up to $5,000 (non-matching) or $4,000 (matching) for other eligible wind-mitigation work.
- Covers upgrades like roof deck attachment, secondary water barrier, roof covering, gable-end bracing, opening protection, and window/door reinforcement.
Eligibility is aimed at owner-occupied primary residences in eligible South Carolina coastal counties. Since 2007 the program has awarded thousands of grants and tens of millions of dollars to coastal homeowners.
One important timing note: the grant runs in funding windows and the money runs out — it isn't always open. As I write this it's between windows. So the move is to get your paperwork and roof scope ready now, then apply the moment the next window opens. Confirm the current status directly at https://doi.sc.gov/605/SC-Safe-Home.
A quieter benefit: mitigation can help you get covered
In today's coastal market, the value isn't only the discount. Carriers are picky about the homes they'll write, and a well-mitigated roof — especially a FORTIFIED one — can be the difference between an offer and a "no." If you've been non-renewed or struggled to find coverage, mitigation is one of the most effective things you can do to get back in the market. (More on that in Non-Renewed by Your Home Insurance Company in South Carolina.)
It also pairs with the reality of coastal deductibles: a stronger roof means fewer claims and less chance of ever paying that big percentage hurricane deductible out of pocket. And if you carry wind coverage through the state Wind Pool, mitigation credits can apply there too.
Putting it together
Here's the simple game plan for a coastal South Carolina homeowner who wants to fight back on premium:
- Get a wind mitigation inspection and send me the report — capture the credits you've already earned.
- If you need a new roof, go FORTIFIED — biggest credit, better insurability.
- Watch for the SC Safe Home grant window and have your paperwork ready to help pay for it.
- Have me re-shop your policy with the credits applied — sometimes the savings plus a better carrier is a dramatic improvement.

Frequently Asked Questions
What are wind mitigation credits in South Carolina? They're premium discounts that South Carolina law requires insurers to offer when your home has features that resist hurricane wind — like hurricane straps, a hip roof, impact-resistant openings, or a secondary water barrier. Combined credits can reach up to 48% of the wind portion of your premium, and the average qualifying homeowner saves around 14%.
How do I get a wind mitigation discount? Have a qualified inspector complete a wind mitigation inspection and document your home's features on the standardized report (OIR-B1-1802 in South Carolina). Give the report to your agent, and the qualifying credits are applied to your policy.
What features qualify for wind mitigation credits? Roof shape (hip roofs earn more), roof deck attachment, roof-to-wall connections (hurricane clips/straps), code-rated roof covering, a secondary water barrier, opening protection (impact windows/doors or shutters), and gable-end and garage-door bracing.
What is a FORTIFIED roof? FORTIFIED is a nationally recognized IBHS construction standard designed to keep roofs on and water out during severe storms. It typically earns among the largest insurance credits and can make a coastal home easier to insure.
How much is the SC Safe Home grant? The SC Safe Home program offers up to $7,500 (non-matching) or $6,000 (matching) for a full FORTIFIED Roof, and up to $5,000 (non-matching) or $4,000 (matching) for other eligible wind-mitigation work, for eligible owner-occupied homes in coastal counties. It runs in funding windows, so check current availability at doi.sc.gov/SC-Safe-Home.
Can wind mitigation help me get insured if I've been non-renewed? Yes. Beyond the discount, a well-mitigated or FORTIFIED roof can make coastal carriers more willing to write your home, which can be the difference between getting an offer and being declined.
