What it really costs, and what you get back
The honest math: the grant is generous but not unlimited, you pay the evaluator either way, and the durable payoff is a legally mandated insurance discount that lasts as long as your certification does.
What the grant pays
Up to $10,000 of construction costs, paid directly to your contractor after the roof is certified. Not a reimbursement to you; you never touch the money.
What you pay
| Item | Amount | Notes |
|---|---|---|
| Evaluator's fees | Set by the evaluator | The state doesn't regulate or publish these. Get the price in writing before booking. Paid even if you don't end up qualifying. |
| Construction above $10,000 | Varies with your roof | IBHS says the FORTIFIED upgrade itself typically adds $1,000–$3,000 to a 2,000 sq ft re-roof. The total job can exceed the grant on larger or complex roofs. |
| Permits and code inspections | Local rates | Required by the statute; grant is contingent on them. |
One Kentucky evaluator estimates full FORTIFIED roof replacements at $12,000–$25,000 all-in. That's a marketing estimate, not an official figure; your quotes are the real number, and getting more than one from the approved list is allowed.
The insurance discount is law, not a favor
Since March 1, 2026, Kentucky law (KRS 304.13-342) requires insurers writing wind and hail coverage to provide a premium discount or rate reduction for homes with a FORTIFIED certificate, where actuarially justified. Send your insurer the certificate; if they receive it, applying the discount is mandatory, not optional.
How much? Kentucky sets no fixed percentage — amounts vary by insurer and their filed rates. Be skeptical of anyone quoting you "30–50% off": no official Kentucky source supports a number like that. Ask your own agent what your carrier files.
The other route: the insurance endorsement
Kentucky insurers must also offer an optional policy endorsement (KRS 304.13-346) that pays to upgrade to a FORTIFIED roof when a covered claim already requires roof replacement. If you miss the grant, this is the backup path: the storm that totals your old roof buys your fortified one. Ask your agent to add it before storm season, not after.
Certification lifespan
The FORTIFIED designation lasts five years and renews through a re-designation inspection. It transfers to the buyer if you sell — which makes it a listing feature, not just an insurance discount.
