What is the FORTIFIED standard, and is it worth it for your home?

FORTIFIED Roof. The starting tier, focused entirely on your roof. It calls for stronger nails and a tighter fastening pattern (ring-shank nails for better roof deck attachment), a sealed roof deck so water stays out even if shingles are lost, reinforced roof edges, and wind- and rain-resistant vents. In testing, a sealed roof deck alone can keep out roughly 95% of wind-driven rain that would otherwise pour through gaps in the sheathing.

FORTIFIED Silver. Everything in Roof, plus protection for the rest of the building envelope: reinforced gable ends and soffits, impact-rated windows and doors in hurricane-prone areas, a pressure-rated garage door, and protection for exposed mechanical and electrical equipment. Think of Silver as tying down every obvious weak point beyond the roof.

FORTIFIED Gold. The full package. Gold adds a continuous load path: engineered connections from roof to walls, walls to floors, and floors to foundation, so the house behaves as one structure under wind and uplift rather than a collection of separately attached parts. This tier requires a structural engineer and is verified in more depth than the other two.

Costs depend on roof size, pitch and condition. Get a written bid from a FORTIFIED-trained roofer.

Silver and Gold don’t have a clean national price range published, since they’re effectively whole-house structural and envelope projects. Treat these as something to get a real bid on from a FORTIFIED-trained contractor and engineer, not a number to estimate from a generic range.

For context on the value: mitigation spending broadly returns about $6 in avoided future losses for every $1 spent, based on a long-running national study of federal mitigation grants. FORTIFIED-specific wind standards carry a similar benefit-to-cost ratio.

Several states now tie FORTIFIED designations directly to insurance discounts, and the specifics vary meaningfully by state:

• Alabama requires insurers statewide to offer FORTIFIED discounts, and Strengthen Alabama Homes pays up to $10,000 toward a FORTIFIED Roof.
• Mississippi’s wind pool (MWUA) offers about 20% off for FORTIFIED Roof, 25% for Silver and 30% for Gold, with some individual insurers offering discounts as high as 55% off the wind portion of the premium.
• North Carolina has a filed rate plan offering FORTIFIED incentives in 18 coastal counties.
• Louisiana’s Regulation 136 requires insurers to discount premiums on FORTIFIED homes statewide, starting with policies issued or renewed on or after January 1, 2027.
• Georgia has incentive frameworks in specific areas as well.
• Kentucky and Oklahoma are launching similar state-backed roof-hardening grant programs, modeled directly on Alabama and Florida, though not always tied to full FORTIFIED certification specifically.

If you’re outside these states, ask your insurer directly. Many carriers offer voluntary mitigation credits even without a state mandate behind them, and that list is actively growing as more insurers respond to rising disaster losses.

1. Find a certified FORTIFIED evaluator. Every designation requires one; there’s no way to get certified without an independent third-party evaluation. IBHS maintains an evaluator directory.
2. Hire a FORTIFIED-trained contractor or roofer alongside your evaluator, ideally before work starts, not after, so the work is documented correctly as it happens rather than inspected after the fact.
3. Complete the retrofit or construction. Your evaluator documents materials (shingle labels, window and garage door ratings, vent specifications) and installation details throughout, not just at the end.
4. Evaluator submits documentation to IBHS, who reviews it and issues the designation certificate.
5. Keep it current. Designations typically last around five years, with re-certification focused mainly on roof condition. Ask your FORTIFIED evaluator for a fee quote up front.
