Home › Is a FORTIFIED roof worth it?
The honest maths · Checked 1 Oct 2026Is a FORTIFIED roof worth it in Oklahoma? With the $10,000 grant, almost always yes. Paying yourself, it comes down to your insurer’s discount and the size of your wind and hail premium. At some insurers’ rates the discount alone takes decades to repay the extra cost; at others it’s three or four years. Here’s the table, so you can find yourself on it.
| Your situation | What you’d pay | Verdict |
|---|---|---|
| 1. Roof needs replacing, you get the grant | On a $14,000 FORTIFIED roof: about $4,500 after the $10,000 grant and a $500 evaluator. A standard roof from the same roofer would be roughly $3,000 to $6,000 less than the FORTIFIED price, so around $8,000 to $11,000, all yours to pay. | Worth it. Cheaper than a standard roof |
| 2. Roof needs replacing, no grant | The FORTIFIED extra only: $1,000 to $6,000 over standard, or $1,500 to $4,000 over a Class 4 roof. | Depends on your discount. Use the table |
| 3. Roof is fine, you’d replace it early | The whole roof, while throwing away the years left on your current one. | Only with the grant. Compare your share with your deductible first |
Prices are Oklahoma contractors’ published ranges (Topside Roofing, Sooner Fortified Roofing). Grant terms from OID. Evaluator fee is a contractor estimate.
Some Tulsa homeowners have replaced roofs that were only about 7 years old. Their reasoning: their share after the grant was smaller than the deductible they’d pay if hail took the roof anyway, and the lower premium covered the rest within two years. Find the dollar figure of your wind and hail deductible on your declarations page. If your share of a grant roof is below it, situation 3 starts to make sense.
| Wind and hail premium a year | 6% (Nationwide) | 14% (Shelter) | 20% (IDS, Goodville) | 30% (State Farm) |
|---|---|---|---|---|
| $1,500 | 33 years | 14 years | 10 years | 6.7 years |
| $2,500 | 20 years | 8.6 years | 6 years | 4 years |
| $3,500 | 14 years | 6.1 years | 4.3 years | 2.9 years |
Our calculation: $3,000 divided by (premium × discount). Discount rates from OID’s sheet based on 2018 rate filings; ask your insurer for today’s rate. The discount applies to the wind and hail portion only, under 36 O.S. § 961 and 962. $3,000 sits in the middle of published FORTIFIED extras.
The discount is the only part you can bank each year, but it isn’t the only return. Verisk found 64.7% of Oklahoma roofs were hit by severe hail in 2025 alone. A roof built to resist that hail, with shingles IBHS rated Good in its lab hail tests, is less likely to need a claim in the first place.
FORTIFIED’s wind evidence comes from the Gulf Coast. OID cites a University of Alabama study of Hurricane Sally that found FORTIFIED homes had 55% to 74% fewer claims and claims 15% to 40% smaller. Oklahoma’s storms are different, so treat that as a signal, not a promise.
If your insurer files a low discount, your premium is small and your roof has years left, the numbers don’t stack up without the grant. Wait for a round, or for the day the roof needs replacing anyway.
If you’re selling within a year or two, you’ll pay the extra and someone else will collect most of the discount.
The table uses round numbers. The calculator on our home page takes your insurer, your premium and your quoted roof price. The insurance discount guide lists every insurer OID published.
If your roof needs replacing and you get the $10,000 Strengthen Oklahoma Homes grant, usually yes: you can end up paying less than for a standard roof. Without the grant it depends on your insurer’s discount and your wind and hail premium.
On a $3,000 extra, from about 3 years (30% discount, $3,500 wind and hail premium) to over 30 years (6% discount, $1,500 premium).
We haven’t found Oklahoma sale-price data. The certificate does transfer with the home, and buyers can use it to claim the discount.
Usually not without the grant. With it, some owners do when their share is smaller than their wind and hail deductible.
Ask for a standard price and a FORTIFIED price together. The gap is the number that matters. Also see published prices.
