FORTIFIED Roof, Silver, Gold: what each level actually requires

FORTIFIED is not a shingle brand and not a marketing badge. It is a construction checklist owned by IBHS, the insurance industry's research lab, published at fortifiedhome.org, and it comes in three levels that nest like rings. Around Lafayette and Baton Rouge, where ultimate design wind speeds sit roughly in the 130 to 140 mph band, per Louisiana wind-load references (exact per-address values come from the ASCE Hazard Tool or your building official), the levels describe how much of the house keeps holding together when that wind arrives. Insurers price the difference, which is why the discount statutes name the standard.

FORTIFIED Roof, requirement by requirement

The entry level is where nearly every existing home starts, and its requirements are specific enough to check on a bid. The sealed roof deck is the signature: taping or sealing the seams between decking panels cuts water intrusion by up to 95 percent when wind strips the covering, per IBHS, which is the difference between replacing shingles and replacing ceilings. The deck gets re-nailed with 8d ring-shank nails, roughly doubling its uplift resistance. Edges get locked down with drip edge of minimum 26-gauge metal, and the covering itself must be impact resistant. The exact nailing patterns and materials are in the prescriptive requirements document LDI publishes, which is the sheet worth handing to any bidder.

For context, Louisiana's code baseline is the 2021 international codes with state amendments, in force since January 1, 2023, per ICC-NTA. FORTIFIED layers its checklist on top of that baseline; the two are related but not interchangeable, and the designation documents the difference. The hurricane upgrades page takes each component one at a time.

The requirements read differently once you remember what they were written against. Laura arrived in 2020 as a Category 4; Delta made landfall 13 miles away 43 days later and cut power to roughly 40 percent of Lafayette, per AccuWeather; Francine pushed sustained winds measured at 44 knots to the LSU campus in Baton Rouge in September 2024, per the National Hurricane Center report. A sealed deck earns its place in the checklist during exactly those hours, when coverings fail and taped seams are what stand between wind-driven rain and the ceiling below.

Silver: the openings and edges of the building

Silver keeps the Roof requirements and moves outward to the places wind gets in: bracing for gable ends, protection for windows and other openings, a garage door rated for wind pressure, and anchoring for attached structures like carports and porches, per the IBHS program pages. The logic is pressurization: a failed garage door or window lets wind load the structure from inside. Most Silver items can be retrofitted on an existing home, which makes it the natural second step when a renovation already has openings or the garage in scope.

Gold: the load path

Gold keeps everything below it and adds the structural spine: an engineered continuous load path tying the roof to the walls and the walls to the foundation, per fortifiedhome.org/gold. Engineered is the operative word; this is design work, not a materials swap, which is why Gold shows up mostly in new construction and structural remodels where an engineer is already at the table.

The evaluator and the five-year clock

No level exists until an independent certified evaluator documents the work and IBHS issues the designation, and the designation is renewed on a five-year cycle, per the FORTIFIED program FAQ. The evaluator is the homeowner's hire, separate from the roofer, and under Louisiana's grant rules a contractor may not evaluate their own project. Expect the file to dwell on the parts of the roof that vanish from view as the job progresses: the deck nailing before underlayment covers it, the seam sealing, the edge metal, and the covering as installed. The evaluation page walks the visits and paperwork.

Which level makes sense, qualitatively

If you are re-roofing an existing house, Roof is the tier the project naturally reaches, the entry point for the discount statute, and the tier the grant program funds when rounds are open. Silver earns its cost most readily where exposure is high or the openings and garage are already being touched. Gold is a decision made at the drafting table. One practical note for bid meetings: name the level in the contract, because almost-FORTIFIED earns nothing. A roof with smooth-shank nails where ring-shank belongs, or unsealed seams under a premium covering, gets no designation and no discount; the evaluator checks the checklist, not the effort. On the money side, the benchmark structure arriving in 2027 varies by designation level as well as region, so higher tiers generally correspond to deeper discounts; the current published ranges and program status sit in the line below, and the cost guide prices the entry tier.
