FORTIFIED roofs and the $10,000 Alabama grant, explained
Alabama has more FORTIFIED homes than every other state combined, over 53,000 of the roughly 80,000 in the country, because it pays for them, discounts them and has the data to show they work. Here's the whole picture for Mobile and Baldwin County.
What FORTIFIED is
FORTIFIED is a set of construction standards from the Insurance Institute for Business & Home Safety, the insurance industry's research lab, built on full-scale wind-tunnel and field testing of what actually fails in hurricanes. It comes in three levels. FORTIFIED Roof is the entry level and the one the grant pays for: a roof designed to stay attached and keep water out of the house even when the shingles are lost. Silver adds protection for openings, gables, attached structures and soffits. Gold ties the whole structure together with a continuous load path. The standard addresses winds to 130 mph, torrential rain, and, with the hail supplement, hail to 2 inches.
What a FORTIFIED Roof requires
The requirements are specific and testable, which is why an independent evaluator has to verify them. The roof deck is re-nailed with ring-shank nails in an enhanced pattern; IBHS testing found that switching to 8d ring-shank nails at tighter spacing can double the deck's uplift resistance. The seams between the deck panels are sealed with tape or a self-adhered membrane, which IBHS says can cut water intrusion by up to 95 percent if the roof covering is lost. The edges get a wider drip edge with a fully adhered starter strip, because hurricane wind attacks a roof at the eaves and rakes first. Attic vents must be rated to resist wind-driven rain. Asphalt shingles must be rated ASTM D3161 Class F or ASTM D7158 Class H; metal, tile and low-slope roofs must be tested to the site's design pressures. The evaluator inspects at the deck stage, before the underlayment covers the nailing and the sealing, and again at completion, and the home receives a designation certificate that your insurer uses.
What it costs
On a Mobile shingle replacement the FORTIFIED steps add roughly $1,500 to $2,500: the ring-shank nailing, the seam tape, the adhered starter, the rated vents, and the evaluator's fee of about $400 to $700. The University of Alabama's research puts the premium at 6 to 16 percent of a retrofit's cost and just 0.5 to 3 percent of new construction. On metal the added cost is mostly in the testing documentation and the deck work underneath. See roof replacement cost in Mobile for the full numbers.
What the data says
In May 2025 the University of Alabama's Center for Risk and Insurance Research, working with the Alabama Department of Insurance, published a study of more than 40,000 houses in Mobile and Baldwin counties, $17 billion of insured value, through Hurricane Sally. FORTIFIED homes had 55 to 74 percent lower claim frequency and 14 to 40 percent lower loss severity. They were almost a quarter of the policies but only 9 percent of the claims. If every home had been FORTIFIED, the study estimated insurer payouts would have been 75 percent lower (up to $112 million) and policyholder deductibles up to 65 percent lower (almost $35 million). The one caveat worth knowing: nearly half the claims involved fallen trees, which the roof standard does not address.
The money: four pieces
| Incentive | What it's worth | Who qualifies |
|---|---|---|
| Strengthen Alabama Homes grant | Up to $10,000 | Primary residences in Mobile and Baldwin counties, no income test, when a window is open |
| Insurance discount (required by 2009 law) | 25% – 35% off the wind premium for FORTIFIED Roof | Any designated home; 35–45% Silver, 45–55% Gold |
| FORTIFIED endorsement (2020 law) | Extra payment toward the upgrade after a covered loss | Available on every Alabama homeowners policy; ask your agent |
| Alabama income-tax deduction | Lesser of 50% of cost or $3,000 | Alabama residents; ask your tax advisor |
How the grant works in 2026
Strengthen Alabama Homes was created by 2011 legislation after Ivan and Katrina, is funded by the Alabama insurance industry and administered by the Department of Insurance, and has paid for more than 8,700 retrofits, about $86 million, since 2015. It pays 100 percent of the FORTIFIED mitigation cost up to $10,000 for an owner-occupied primary residence. In 2026 it opened quarterly, for Mobile and Baldwin County homeowners only, on separate days: Mobile on January 6, April 7, July 7 and October 6; Baldwin on January 8, April 9, July 9 and October 8. Applications go through strengthenalabamahomes.com, the official schedule is on the Grant Schedule page of that site, and the program line is 1-800-433-3966. Demand is far above supply and windows fill in hours, so have your account set up, your documents ready, and be online when the window opens. Once approved, you choose a participating contractor, the roof is built to the standard, the evaluator verifies it, and the program pays.
What to ask your roofer
Whether they've built FORTIFIED roofs before and can name the evaluator they work with; whether they re-nail and seal the deck on every roof or only when asked; which Class H shingles or tested metal system they'll use; whether the evaluator's fee is in the price; and whether they'll help with the application. And ask for the HBLB license card. We build every roof to the standard, designation or not, because it's the right roof for this coast. See our FORTIFIED roof service.
Common questions
Do I have to replace my roof to get FORTIFIED?
Yes. The deck re-nailing and sealing happen with the shingles off, and the evaluator has to see the deck before it's covered. The grant exists for exactly that moment.
Is the grant only for Mobile and Baldwin?
In 2026, yes; those are the counties with the coastal wind exposure. A November 2025 window for Jefferson, Tuscaloosa and Escambia was the first expansion beyond the coast since 2015, and the program's schedule page is the place to watch.
What if I miss the window?
Build to the standard anyway, get the designation, and take the discount; on a coastal policy it pays back the upgrade in a few years. If your roof can wait, we'll time the job to the next quarterly opening.
How much will my premium drop?
IBHS reports 25 to 35 percent off the wind portion for FORTIFIED Roof with most Alabama carriers, and the law requires insurers to offer a discount. On the coast, wind is most of the premium. Ask your agent for the exact figure with the certificate in hand.
Does FORTIFIED protect against trees?
No. The Sally study found nearly half the claims involved fallen trees, which the standard doesn't address. Tree work before the season is the other half of hurricane prep.
Can a metal roof be FORTIFIED?
Yes, when the panels and attachment are tested to the site's design pressures and the deck underneath is sealed and re-nailed. Many Eastern Shore FORTIFIED roofs are standing seam.
