FORTIFIED Roofs in Louisiana: Requirements, Cost & Process

A FORTIFIED roof is built to a research-based standard from the Insurance Institute for Business & Home Safety (IBHS), and the work is independently verified before IBHS issues a designation. This guide explains what goes into one, how verification works, what affects cost, how FORTIFIED homes performed in a real hurricane, and where to check Louisiana grants and insurance incentives. GSAS Construction Group is a certified FORTIFIED Roof installer.

The Quick Answer

What Is a FORTIFIED Roof?

FORTIFIED is a voluntary construction and re-roofing program created by IBHS, a nonprofit research organization supported by property insurers and reinsurers. IBHS tests full-size buildings under wind, wind-driven rain and hail conditions at its research center in South Carolina, and uses that research to set the FORTIFIED standards.^[1]^[2]

A FORTIFIED roof isn’t a brand of shingle. It’s a complete roofing system built to specific requirements — how the deck is attached and sealed, how edges, vents and the roof covering are installed — and then verified: an independent evaluator documents the work and IBHS reviews it before issuing a designation for your home. That verification is what separates a FORTIFIED roof from a roof that’s simply described as “storm-ready.”

How a Roof Fails in a Storm

The shingles you can see are only one part of your roofing system. In a storm, wind can damage the roof covering, lift its edges, or even detach the decking underneath. Once the covering is gone, rain can pour in through the joints between deck boards — soaking insulation and ceilings even when the roof structure itself survives.^[3]

The attachment, edge details and water-resistant layers beneath your shingles are what matter most when a storm tests your roof. That’s exactly what FORTIFIED focuses on.

What Happens Beneath Your Shingles

The Principal FORTIFIED Roof Upgrades

These summarize the 2025 FORTIFIED standard, which applies to roofs permitted (or, where no permit is required, installed) on or after November 1, 2025. Your contractor and evaluator confirm the exact assembly for your home, site and materials.^[4]^[5]

UPGRADE 1

Stronger deck attachment

Old roofing is removed, damaged wood is replaced, and the roof deck is fastened to the framing with specified ring-shank nails — the standard detail uses 8d ring-shank nails at 4-inch spacing. IBHS reports enhanced attachment with ring-shank nails can roughly double uplift resistance compared with common smooth nails.^[3]^[4]

UPGRADE 2

A sealed roof deck

The seams between deck boards are sealed with an approved system — seam tape with specified underlayment, a qualifying two-layer underlayment, or a full self-adhered membrane. If the shingles are torn off, this layer keeps rain out of your attic. IBHS reports it can reduce that water intrusion by up to 95% under its testing conditions.^[3]^[4]

UPGRADE 3

Strengthened edges & flashing

Roof edges are where wind gets a grip, so the standard specifies reinforced edge details and proper flashing around the perimeter and penetrations.^[3]^[4]

UPGRADE 4

Tested roof covering

Asphalt shingles must be rated ASTM D3161 Class F or ASTM D7158 Class H and installed with six nails each per the manufacturer’s high-wind instructions. Metal, tile and low-slope systems can also qualify when the assembly carries the required design-pressure ratings.^[3]^[4]

UPGRADE 5

Wind- and rain-resistant vents

Ridge and off-ridge vents must be tested (TAS 100(A)) to resist wind-driven rain. Near saltwater shorelines, corrosion-resistant fasteners are required, and hurricane designations also call for temporary storm protection for gable vents.^[4]

UPGRADE 6

Independent verification

A third-party FORTIFIED Evaluator documents the required elements during the project — including the deck before it’s covered — and IBHS reviews that documentation before issuing a designation.^[1]

Test results like “up to 95%” and “roughly double” are component-level findings under IBHS testing conditions, not guarantees for a whole house. See the full technical checklist.

A Regular Re-Roof vs. a FORTIFIED Roof Scope

Plenty of conventional roofs are well built. The difference is that a FORTIFIED scope spells out specific requirements and has them verified by a third party.

	Regular re-roof	FORTIFIED Roof scope
Tear-off & decking	Varies by job and local code	✓ Full removal, damaged wood replaced, minimum 7/16″ decking
Deck attachment	Varies by job and local code	✓ Specified ring-shank nails (standard detail: 8d at 4″)
Deck seams	Varies by job and local code	✓ Sealed with an IBHS-approved system
Shingles	Manufacturer’s standard install	✓ Class F or Class H rated, six nails, high-wind install
Roof vents	Varies	✓ Tested for wind-driven rain (TAS 100(A))
Who checks the work	The contractor and any local inspection	✓ Independent FORTIFIED Evaluator, then IBHS review
Proof you can show	Your invoice and warranties	✓ IBHS designation certificate, plus your warranties

Roof, Silver and Gold

FORTIFIED builds in layers, and each level includes everything before it. A roof replacement earns a FORTIFIED Roof designation — it doesn’t mean the whole home meets Silver or Gold.

FORTIFIED Roof

Focuses on the roof system — attachment, sealed deck, edges, covering and vents. It addresses a major source of storm damage, and it’s the level most homeowners pursue when replacing a roof.

FORTIFIED Silver

Everything in Roof, plus protection for additional vulnerable parts of the home, such as reinforced gable ends, chimneys and attached structures, and pressure-rated garage doors. Exact requirements depend on the standard and location.^[6]

FORTIFIED Gold

Everything in Roof and Silver, plus a continuous structural load path that connects the home from the roof through the walls to the foundation.^[7]

Hail protection is a separate, optional Hail Supplement — ask whether your estimate includes it.^[3]^[5]

How FORTIFIED Designation Works

IBHS issues the official designation after reviewing the evaluator’s documentation. Here’s what the journey looks like with GSAS:^[1]

Talk through your roof

We review your roof’s condition, your location, the level you want, and whether you plan to apply for a grant.

Check eligibility & line up the evaluator

Your home’s eligibility is reviewed and an independent FORTIFIED Evaluator is identified — before any work begins.

Get a written scope

Your estimate names the standard that applies, the exact materials, who is responsible for what, and every fee.

Build & document

Construction is photo-documented while the deck, fasteners and sealing are still visible, then the finished roof is documented too.

Evaluator submits to IBHS

The evaluator submits the compliance package, and IBHS reviews it against the standard.

Receive your certificate

If approved, IBHS issues your FORTIFIED designation certificate. Keep it somewhere safe.

Send it to your insurer

Give your carrier the certificate to ask about discounts, and note the expiration date.

Because the evaluator has to document components before they’re covered, FORTIFIED must be planned before work begins — it can’t be added to a finished roof. Under the 2025 standard, FORTIFIED Roof components must be installed by a qualified FORTIFIED Wise roofing contractor with an active directory listing.^[5]

Can My Existing Home Qualify?

An existing home may qualify, but eligibility and the work needed should be checked before construction. The official eligibility review looks at the dwelling type, foundation, roof areas, framing, decking, rooftop equipment and accessories. A few examples of what can come up:^[8]

✓Dry-stack foundations are not eligible
✓Duplexes and townhomes can require participation from the other owners
✓Manufactured homes need specific HUD and foundation documentation, and elevated homes may need foundation photos
✓Rooftop decks and HVAC units can require an engineering analysis
✓Older wood-board decking with large gaps needs additional consideration

Screening isn’t a guarantee of designation. Your evaluator can flag issues that affect the scope and budget before you commit.

Evidence From a Real Hurricane

How FORTIFIED Homes Fared in Hurricane Sally

A University of Alabama study commissioned by the Alabama Department of Insurance examined insured homes hit by Hurricane Sally in coastal Alabama. Across the FORTIFIED levels studied, FORTIFIED homes came out well ahead of comparable homes:^[7]

55–74%

lower loss frequency — FORTIFIED homes had fewer claims

15–40%

lower claim severity — claims that did occur were smaller

40,000+

insured homes studied, including 1,705 FORTIFIED Roof and 5,712 FORTIFIED Gold homes

Silver wasn’t studied because its sample was too small, and tree-related claims were excluded. These findings describe that storm and study population — they aren’t a forecast of any individual homeowner’s savings.

Cost

What Does a FORTIFIED Upgrade Cost?

IBHS gives a typical range of $1,000 to $3,000 for the FORTIFIED upgrade on a re-roof of a 2,000-square-foot home. That’s the added cost on top of the roof replacement — not the full roof price, and not a local quote. Your roof’s condition, size, pitch, materials and any hidden deck damage all affect the final number.^[1]

A complete FORTIFIED estimate should clearly show:

✓The base re-roofing work and the additional FORTIFIED scope, shown separately
✓Removal, disposal, and how decking or framing repairs will be priced
✓The specified roof covering, sealing method, edge details, flashing and vents
✓The evaluator fee, documentation charges, and who submits to IBHS
✓Whether the optional Hail Supplement is included, and its added cost
✓Any engineering, unusual roof conditions or rooftop equipment work
✓Written allowances and how you’ll approve hidden damage found during tear-off
✓Payment schedule, plus the manufacturer and workmanship warranties
✓Who fixes an incomplete or noncompliant submission

Louisiana Grants & Insurance Incentives

Louisiana Fortify Homes Program grants

The Louisiana Department of Insurance offers grants of up to $10,000, limited to construction costs, in periodic rounds — check the LDI website for whether registration is open. Requirements include a primary residence with a homestead exemption, active insurance with wind coverage, and flood insurance where the program requires it. New construction, condominiums, mobile homes, and roof patching or partial repairs are excluded, and eligible parishes are listed for each round.^[9]

Important: the program does not fund homeowners who fortify first without receiving a grant. If you plan to apply, don’t start work until the grant process allows it. Grant eligibility and FORTIFIED designation eligibility are also separate — qualifying for one doesn’t establish the other.

Insurance discounts

Louisiana law provides for insurance premium discounts on FORTIFIED-certified homes. IBHS reports Louisiana examples exceeding 50% of the wind and hail portion of premiums, and some policies offer endorsements that may help pay for a FORTIFIED upgrade after a covered roof-replacement loss. Availability, limits and pricing vary by insurer.^[10] Questions to ask your carrier:

✓What credit applies to my home and designation level?
✓Does it apply to my whole premium or only the wind and hail portion?
✓What certificate or documentation do you need?
✓Do I need a current designation to keep the credit?
✓Do you offer a FORTIFIED upgrade endorsement, and what triggers payment?

Grants and discounts are set by the State of Louisiana and individual insurers and can change. You may qualify, but no grant or premium reduction is guaranteed. Reviewed October 2026.

How Long a Designation Lasts

Initial FORTIFIED certificates generally expire five years after they’re issued, and homes can be redesignated.^[1] IBHS bulletin FH 2026-03, released September 29, 2026, adds eligibility limits for asphalt-shingle roofs on applications submitted on or after January 1, 2027:^[11]

✓New Roof designation: generally up to 15 years from the initial designation
✓Existing roof with a documented installation date: generally up to 15 years from the shingle installation date
✓Existing roof with an unknown installation date: one initial term of up to five years, with replacement needed before redesignation

The bulletin doesn’t shorten terms issued before January 1, 2027, and it isn’t a general shingle service-life rule. Your evaluator can explain what applies to your roof.

What FORTIFIED Doesn’t Do

FORTIFIED is designed to reduce damage risk. To be clear, it does not:^[1]^[7]

✓Make your home hurricane-proof, tornado-proof or stormproof — keep following evacuation and shelter instructions
✓Protect against falling trees, which the Hurricane Sally study excluded because FORTIFIED isn’t designed for that hazard
✓Include hail protection automatically — the Hail Supplement is a separate, optional upgrade
✓Replace your warranties — the IBHS designation is separate from your manufacturer and workmanship warranties, and IBHS does not insure your roof

FORTIFIED Roof FAQs

What is a FORTIFIED roof?

A FORTIFIED roof is built or replaced to the FORTIFIED Roof standard from the Insurance Institute for Business & Home Safety (IBHS). It's a complete set of requirements for how the roof deck is attached and sealed, how edges, vents and the roof covering are installed, and how the work is verified by an independent evaluator before IBHS issues a designation.

Is FORTIFIED a special shingle?

No. FORTIFIED is a roofing system standard, not a product. Asphalt shingles, metal, tile and low-slope systems can all qualify when the specific assembly meets the program's requirements.

Who verifies a FORTIFIED roof?

An independent FORTIFIED Evaluator checks and documents the required elements during the project, including parts that will be covered up. The evaluator submits the documentation to IBHS, and IBHS issues the designation if the roof meets the standard.

Who can install a FORTIFIED roof?

Under the 2025 standard, FORTIFIED Roof components must be installed by a qualified FORTIFIED Wise roofing contractor with an active directory listing. A contractor's listing is a provider qualification; your home's designation is a separate, project-specific outcome. It's worth verifying both.

Can my existing home qualify?

Often, yes, but it should be checked before construction. The eligibility review looks at the dwelling type, foundation, roof areas, framing, decking and rooftop equipment. Some homes need extra steps (for example, rooftop decks or HVAC units can require engineering), and dry-stack foundations are not eligible.

Is hail protection included?

Not automatically. The Hail Supplement is optional. Under the 2025 standard, asphalt shingles need a Good or Excellent rating in IBHS's hail ratings to qualify for it, and an impact rating alone no longer qualifies asphalt shingles.

How much does a FORTIFIED upgrade cost?

IBHS gives a typical range of $1,000 to $3,000 for the FORTIFIED upgrade on a re-roof of a 2,000-square-foot home. That's the added cost on top of the roof replacement, not the full price, and your actual cost depends on your roof's condition, size, and materials.

Does a FORTIFIED roof really perform better in hurricanes?

In a University of Alabama study of more than 40,000 insured homes hit by Hurricane Sally in coastal Alabama, FORTIFIED homes had 55% to 74% lower loss frequency (fewer claims) and 15% to 40% lower claim severity than comparable homes. Results describe that storm and study group, not a guarantee for any individual home.

Can I get a Louisiana grant for a FORTIFIED roof?

You may qualify for a Louisiana Fortify Homes Program grant of up to $10,000 toward construction costs when a grant round is open. Requirements include living in the home with a homestead exemption and carrying insurance with wind coverage. Check the Louisiana Department of Insurance website for current enrollment.

Should I start my roof before I get a grant?

No, not if you want the grant. The Louisiana Fortify Homes Program does not fund homeowners who fortify first without receiving a program grant. If you plan to apply, wait for the grant process before starting work.

Will a FORTIFIED roof lower my insurance?

It may. Louisiana law provides for insurance premium discounts on FORTIFIED-certified homes, and IBHS reports Louisiana examples exceeding 50% of the wind and hail portion of premiums. The amount depends on your insurer, home and designation level, so ask your carrier what applies to you.

How long does a FORTIFIED designation last?

Initial certificates generally expire five years after they're issued, and homes can be redesignated. Starting with applications submitted on or after January 1, 2027, IBHS bulletin FH 2026-03 also limits how long asphalt-shingle roofs stay eligible (generally 15 years from the initial designation or shingle installation date). Your evaluator can explain what applies to your roof.

Does a FORTIFIED roof mean I don't need to evacuate?

No. FORTIFIED reduces damage risk, but IBHS is clear that it doesn't make a home hurricane-proof or stormproof. Always follow evacuation and shelter instructions.

Is GSAS Construction Group a certified FORTIFIED Roof installer?

Yes. GSAS Construction Group is a certified FORTIFIED Roof installer listed in the FORTIFIED Wise contractor directory, a HAAG Certified Inspector, BBB A+ accredited, and a licensed, bonded, and insured Louisiana contractor serving Livingston, East Baton Rouge, Ascension, St. Tammany, Tangipahoa, and West Baton Rouge parishes.
