Choosing between two IBHS designations that protect different building layers, and which one your insurer will actually price.
The 2025 FORTIFIED Home Standard (effective 2025-11-01) defines two parallel designations: FORTIFIED Home, Hurricane & Hail (coastal) and FORTIFIED Home, High Wind & Hail (inland). Kentucky, Indiana, and Ohio fall entirely under the High Wind & Hail track. Within each track sit three ascending tiers: Bronze, Silver, Gold.
The tier list tracks what IBHS calls the "building envelope layers." Bronze covers roof only. Silver adds the second layer (wall continuity, anchored connections, opening protection for certain zones). Gold binds the third layer (a continuous load path that ties all the structural elements together). The cost gap between tiers is real, but the insurance-discount gap is often larger than the construction-cost gap, depending on carrier and county.

Per the 2025 FORTIFIED Home Standard, the roof covering must be rated to a target wind speed that matches the geographic design wind speed for the county. The roof deck attachment schedule is prescribed at a higher density than typical residential code. HECS typically finds builders underestimate this, the code-minimum 8d nails at 6-inch spacing is rarely sufficient for Silver.
Gold adds the continuous load path: prescriptive strap or connector schedules from rafter to top plate to stud to foundation. In a typical two-story Kentucky home, Gold drives a roughly 15-25% premium over Silver based on connector material costs alone (HECS project data ranges, IBHS does not publish a single national cost figure). For ranch or single-story homes the gap shrinks because the load path is shorter.
| FORTIFIED Tier | Roof Layer | Wall / Opening Layer | Continuous Load Path |
|---|---|---|---|
| Bronze | Sealed deck, rated shingles | Not required | Not required |
| Silver | Sealed deck, ring-shank nails, rated covering, anchored gables/branches/bracing | Not required at base; opening protection added for severe inland zones | Not required |
| Gold | Same as Silver | Required in specified zones | Full prescriptive strap schedule, top-to-foundation |
The opening-protection rule for inland Silver or Gold lives in the 2025 standard; specific wind-zone triggers determine whether impact-rated windows or rated shutters are mandated. Coastal Hurricane designations always require the full opening-protection layer; inland Kentucky projects usually escape that requirement except in high-wind corridors.
Insurance discount magnitudes are set carrier-by-carter and county-by-county. Public filings and carrier rate filings vary year to year. HECS commonly sees:
These are ranges compiled from HECS engagement files, not vendor-published numbers. The dollar payback period for Gold versus Silver usually lands between 4 and 9 years depending on annual premium and loan structure. Builders and developers pricing Gold for a buyer should request a carrier-specific quote before committing to the standard, sometimes the discount structure favors Silver plus a separate impact-rated shingle upgrade over a full Silver-to-Gold jump.
A common pitfall on FORTIFIED projects: the framing crew delivers Silver or Gold documentation, then the HVAC and insulation subs assume the air-leakage work is covered. It is not. The 2024 IECC R402.4.1.2 requires blower-door testing per ASTM E779 for jurisdictions enforcing 2024 IECC. Per Table R402.4.1.1, the binding ceiling for Climate Zones 4A and 5A is 3.0 ACH50, not 5.0. Kentucky and Indiana projects in HECS's service area are almost universally CZ 4A or 5A, so the 3.0 ceiling is always the operative number in this geography.
Duct tightness is governed separately by 2024 IECC R403.3.5 at 4 CFM25 per 100 ft² conditioned floor area when ducts run through unconditioned attic or basement. FORTIFIED High Wind & Hail does not retest duct leakage; the IBHS evaluator inspects connections and bracing but does not run a Duct Blaster. Two separate verifications must close out.
Working with HECS, HECS delivers blower door and duct leakage testing as standalone scopes or bundled with FORTIFIED evaluation for Kentucky, Indiana, Ohio, Tennessee, Illinois, and Missouri projects. The same NIST-calibrated fan verifies the air barrier the FORTIFIED evaluator separately inspected. HECS produces combined reports so the builder submits one package to the IBHS provider and the code official at once. Reach out via HECS contact or call (859) 983-7382.
HECS is an IBHS FORTIFIED Home Evaluator and runs the airtightness, duct, and combustion deliverables on Silver and Gold projects throughout our service area. Our package includes:
For projects pursuing ENERGY STAR Multifamily New Construction or NGBS Green simultaneously, our verifier team can stage the airflow deliverables to satisfy both the 2024 IECC and the ENERGY STAR MFNC v1.3 (Rev05) functional-testing checklist.
Is FORTIFIED Gold a meaningful upgrade over Silver for inland Kentucky? For sites with elevated design wind speed or recent hail-loss history, yes, Gold adds the prescriptive load path that keeps the roof attached under sustained uplift, which Silver does not. For sheltered interior-zone lots, Silver often gives better dollar-for-dollar storm protection per dollar spent. Run the carrier quote before deciding.
Does the 2025 FORTIFIED Home Standard change the Silver vs Gold cost gap? Material-cost percentages have held roughly steady across the 2020 and 2025 versions for inland High Wind projects, but the 2025 standard tightened opening-protection triggers for some wind zones, which can push Silver projects into requiring rated shutters or impact glass where 2020 did not. Have your evaluator confirm zone-specific triggers before design final.
Can HECS bundle FORTIFIED evaluation with code-required blower door and duct leakage testing? Yes. HECS delivers IBHS evaluation, ASTM E779 blower door testing to the 2024 IECC Table R402.4.1.1 ceiling of 3.0 ACH50, and duct leakage to outside per 2024 IECC R403.3.5 as a single field visit with combined reporting.
HECS serves Kentucky, Indiana, Ohio, Tennessee, Illinois, and Missouri from the Louisville base, with active city clusters in Louisville KY, Lexington KY, Cincinnati OH, Indianapolis IN, Evansville IN, Nashville TN, and St. Louis MO. Silver and Gold scopes run from schematic review through final verification, with the IBHS designation documentation bundled to the airtightness and duct package so the project has one source of truth.
