What is the average cost of a fortified roof?

A FORTIFIED roof (the IBHS hurricane-resilience certification) typically runs 10 to 20% more than a standard FBC-compliant replacement. On a 2,000 sq ft Treasure Coast home, that puts pricing at roughly $10,800 to $46,000 in 2026. The premium covers wider drip edge, fully sealed roof deck (tape over every seam), ring-shank nails in a 6/6 pattern, and a certified third-party inspection. Material choice still drives most of the price. Metal and tile cost more than architectural shingle even at FORTIFIED spec. Insurance discounts often recover the upgrade cost in 5 to 8 years through wind-premium reductions on Florida carriers.
