The 2025 FORTIFIED Home Standard took effect November 1, 2025 — here is what changes for inland Kentucky wind-zone projects.
Kentucky sits outside the High Velocity Hurricane Zone, so most of the state's residential builders spent the last decade ignoring FORTIFIED as a coastal program. That posture is now obsolete. Carrier discounts through national re-insurers and a wave of inland catastrophe losses have pushed IBHS FORTIFIED Home High Wind & Hail into the mid-South as a premium-rated construction option, and Kentucky builders pursuing FORTIFIED Silver or Gold in 2026 are hitting a revised roof-covering checklist that the 2025 Standard introduced.
Three recurring failures show up on HECS evaluations of in-progress FORTIFIED jobs in Jefferson, Fayette, and Boone counties. First, roofers submit shingle manufacturer documentation that proves ASTM D7158 Class H or D3161 Class F rating but lacks the IBHS-accepted sealed-edge or wind-set pattern spec — and FORTIFIED High Wind & Hail requires both the shingle rating and the manufacturer-listed high-wind installation pattern. Second, starter strip and hip/ridge cap specifications are not matched to the field shingle in the re-roof documentation packet. Third, sealed roof deck seams are missing on roughly one in four re-roof submittals we review, even though the 2025 Standard tightened the seam-tape requirement to all seams, not just interior panel seams.
These failures are not theoretical — they delay FORTIFIED designation until the failed checklist items are re-photographed and re-submitted, typically adding two to six weeks to close-out.

The High Wind & Hail designation is the inland designation, with Bronze, Silver, and Gold tiers — Silver requires the Roof layer; Gold adds the Windows and Annex layers.
For the roof covering layer specifically, the 2025 FORTIFIED Home Standard requires: asphalt shingles rated to ASTM D7158 Class G or H or ASTM D3161 Class F; manufacturer's high-wind installation pattern followed across field, starter, and hip/ridge cap; a sealed roof deck (taped seams on the entire deck, not just panel-to-panel interior seams); and roof deck attachment documented at 8d nails at 6-inch edge / 12-inch field spacing minimum (or existing attachment verified by an IBHS evaluator). Each checklist item carries a photograph, a manufacturer documentation reference, and a field-verification signature.
Kentucky is not in a hurricane zone, so FORTIFIED Hurricane — which carries impact-rated window and opening protection requirements — is typically not the right designation. For projects in Louisville, Lexington, and most of central Kentucky, the path is FORTIFIED Home — High Wind & Hail, with climate and design wind speed matched to ASCE 7 figures the IBHS evaluator pulls per county.
HECS provides FORTIFIED Home evaluations for Kentucky, Indiana, Ohio, Tennessee, Illinois, and Missouri projects. Our IBHS-trained evaluator scopes the roof-covering checklist, the sealed-deck checklist, and the documentation packet before the roofer starts — eliminating most re-submission cycles. For a scope call: (859) 983-7382 or hecsusa.com/contact/.
A typical FORTIFIED High Wind & Hail engagement on a Kentucky re-roof breaks into three visits. Pre-roof: HECS reviews the existing deck attachment, confirms the IBHS-required underlayment and seam-tape products, and issues a written scope that the roofer can hand to the shingle manufacturer's representative. This prevents the common mismatch where the shingle is spec'd at Class H wind rating but the starter strip on the estimate is a different product line.
Mid-roof: HECS returns when the deck is exposed (before underlayment goes down) to photograph the deck nailing pattern and the seam-tape application on every panel edge, valley, and penetration. This is the single most valuable site visit — sealed-deck failures caught here are a one-day fix; sealed-deck failures caught after shingles are on are a re-roof.
Final: HECS verifies the roof-covering layer on the ground and in the attic where applicable, audits the documentation packet against the FORTIFIED Home 2025 checklist, and submits the compliance file to IBHS. The HECS deliverable is the signed FORTIFIED evaluation that IBHS uses to issue the Silver or Gold designation.
For projects pursuing FORTIFIED Gold on existing homes, HECS also evaluates the window opening protection checklist and the Annex / continuous wall-to-foundation load path — the third-party verification package IBHS requires for the Gold tier.
Every HECS FORTIFIED evaluation produces a single PDF deliverable — a checklist aligned to the 2025 FORTIFIED Home Standard with photograph callouts keyed to each line item. For the roof covering layer, the report includes:
| Checklist Item | What HECS Verifies | Acceptable Evidence |
|---|---|---|
| Shingle rating | Class G/H per ASTM D7158 or Class F per ASTM D3161 | Manufacturer packaging photo + spec sheet |
| High-wind pattern | 6-nail pattern per shingle where manufacturer requires | Photo of nail pattern on field shingle |
| Sealed roof deck | All seams taped, not just panel interior | Mid-roof deck photo with tape visible |
| Roof deck attachment | 8d nails, 6" edge / 12" field minimum | Photo of nailing at eave edge + interior |
| Starter/ridge match | Same product line as field shingle | Manufacturer documentation cross-reference |
The deliverable goes to the IBHS FORTIFIED Home reviewer; HECS does not issue the designation — IBHS does. HECS issues the evaluation that the designation is based on, which is why evaluator independence and IBHS credentialing matter.
For projects that stack FORTIFIED with ENERGY STAR or NGBS certification, HECS can pull blower door and duct leakage data into the same field visit — verified per 2024 IECC R402.4.1.2 (the section that governs residential blower door testing, often confused with the duct tightness section R402.4.2). For Kentucky and Indiana projects in climate zones 4A and 5A, the binding blower door ceiling is 3.0 ACH50 per Table R402.4.1.1 — not the 5.0 number that the 2018 IECC mapped to zone 4.
Does FORTIFIED Home 2025 require a sealed roof deck on every project, or only on re-roofs? The 2025 Standard requires a sealed roof deck on every FORTIFIED designation — new construction and re-roof — under the High Wind & Hail and Hurricane Silver tiers. Tape must cover all panel seams, including those on panel edges that fall at hips, valleys, and penetrations, not just the panel-to-panel interior seams. HECS catches the edge-seam miss on roughly one in four in-progress Kentucky re-roofs in our experience.
Can a Kentucky FORTIFIED project use a shingle rated Class G under ASTM D7158 instead of Class H? Yes for High Wind & Hail — Class G and Class H are both acceptable under the 2025 Standard, provided the manufacturer's high-wind installation pattern is followed. Class F under ASTM D3161 is also accepted. What is not acceptable is the old approach of citing a manufacturer's warranty wind speed without naming the ASTM test method and class on the documentation. HECS verifies the ASTM citation line by line.
How does FORTIFIED interact with ENERGY STAR Multifamily New Construction or NGBS-2023 on a Kentucky project? FORTIFIED is a construction method standard, not an energy or green standard, so it stacks cleanly with ENERGY STAR MFNC v1.3 (Rev05) or NGBS-2023. HECS holds IBHS FORTIFIED, RESNET HERS Rater, and NGBS Green Verifier credentials, which lets us pull the FORTIFIED evaluation, blower door, and duct leakage into a single site-visit package for multifamily projects.
HECS provides FORTIFIED Home evaluation, blower door, and duct leakage services across Kentucky, Indiana, Ohio, Tennessee, Illinois, and Missouri. A typical FORTIFIED High Wind & Hail evaluation on a Kentucky re-roof runs three site visits and is delivered as an IBHS-acceptable documentation packet. HECS also serves Louisville KY, Lexington KY, Cincinnati OH, Indianapolis IN, and Nashville TN directly — call (859) 983-7382, email [email protected], or submit a scope request at hecsusa.com/contact/ for a written proposal.
