FORTIFIED Roofing: Complete Guide to Hurricane-Resistant Homes
FORTIFIED certification is the gold standard for hurricane-resistant roofing. This guide explains the program, certification levels, insurance savings, and how to get your roof FORTIFIED-certified in Louisiana and Texas.
FORTIFIED is not just another roofing standard—it's a scientifically proven system for building homes that survive hurricanes, severe thunderstorms, and high winds. Developed by the Insurance Institute for Business & Home Safety (IBHS), FORTIFIED standards have been tested against real-world storms and deliver measurable results.
This guide covers everything you need to know about FORTIFIED roofing: what it is, the certification levels, how much you can save on insurance, and the process for getting your home certified. In our Louisiana market, 72% of the roofs we install are FORTIFIED-certified because the benefits far outweigh the costs.
What is FORTIFIED?
FORTIFIED is a voluntary construction and re-roofing program developed by IBHS, an independent nonprofit funded by insurance companies. The program establishes building standards that go beyond minimum code requirements to provide meaningful protection against hurricanes, high winds, hail, and severe thunderstorms.
Why FORTIFIED Matters
Standard building codes establish minimums—they're designed to prevent catastrophic failure, not to prevent damage. FORTIFIED standards address the vulnerabilities that cause most storm damage:
- Roof-to-wall connections — The roof staying attached to the house during high winds
- Roof deck attachment — The plywood staying attached to the rafters
- Sealed roof deck — Preventing water intrusion even if shingles blow off
- Edge and ridge protection — Reinforcing the most vulnerable areas
- Proper ventilation — Maintaining attic pressure balance during storms
Proven Performance
FORTIFIED isn't theoretical—it's been validated by real hurricanes:
- Hurricane Michael (2018) — FORTIFIED homes in Mexico Beach, FL survived Category 5 winds while neighboring homes were destroyed
- Hurricane Laura (2020) — Studies showed FORTIFIED homes had significantly less damage than conventional construction
- Hurricane Ida (2021) — FORTIFIED homes in Louisiana demonstrated markedly better performance
Our perspective: We've seen the difference firsthand. After every major storm, we return to neighborhoods where we've installed both FORTIFIED and conventional roofs. The FORTIFIED roofs consistently perform better—fewer missing shingles, no water intrusion, less damage to call back and repair.
FORTIFIED Certification Levels
FORTIFIED offers three certification levels, each building on the previous one. For roof replacements, most homeowners pursue FORTIFIED Roof (the entry level), which provides the majority of the protection benefits.
FORTIFIED Roof™ (Bronze)
The most common certification for existing homes having their roof replaced. FORTIFIED Roof focuses on the roof system alone.
Requirements include:
- Sealed roof deck (self-adhering underlayment or sealed plywood joints)
- Enhanced nail pattern (more nails, closer spacing)
- Proper drip edge and starter strip installation
- Ridge cap shingles with enhanced fastening
- Attic ventilation meeting specific standards
- All roof penetrations properly sealed
Best for: Homeowners replacing their roof who want insurance discounts and better storm protection without structural modifications.
FORTIFIED Silver™
Adds opening protection (windows and doors) to the FORTIFIED Roof requirements. Windows and doors are the second most common failure point in hurricanes after roofs.
Additional requirements:
- Impact-rated windows and doors, OR
- Tested hurricane shutters for all openings
- Reinforced garage door (common failure point)
Best for: Homeowners doing a comprehensive renovation who want whole-house protection.
FORTIFIED Gold™
The highest level, adding structural requirements to connect the entire load path from roof to foundation.
Additional requirements:
- Roof-to-wall connections (hurricane straps or clips)
- Wall-to-floor connections
- Floor-to-foundation connections
- Continuous load path from roof to ground
Best for: New construction or major renovations where walls are open for structural work.
Insurance Savings
The most immediate benefit of FORTIFIED certification is insurance premium reduction. Louisiana is unique in mandating these discounts by law.
Louisiana Insurance Discounts (Mandatory)
Louisiana law requires insurance companies to offer premium discounts for FORTIFIED-certified homes. The discounts apply to the wind/hurricane portion of your premium:
- FORTIFIED Roof — 20-35% discount on wind premium
- FORTIFIED Silver — 35-45% discount on wind premium
- FORTIFIED Gold — 45-52% discount on wind premium
For a typical Louisiana homeowner paying $4,000-$8,000 annually for insurance, a FORTIFIED Roof designation can save $800-$2,800 per year.
Texas Wind/Hail Discounts
While Texas doesn't mandate FORTIFIED discounts like Louisiana, many insurers offer credits for FORTIFIED certification or specific FORTIFIED features:
- Impact-resistant roof covering discounts (10-28%)
- Sealed roof deck credits
- Enhanced roof-to-wall connection credits
Contact your Texas insurer to ask specifically about FORTIFIED discounts—availability varies by carrier.
ROI Calculation Example
Here's a real-world example from our Louisiana market:
Sample FORTIFIED ROI (Louisiana)
- Standard roof replacement cost: $18,000
- FORTIFIED upgrade cost: +$2,500 (additional materials and labor)
- Annual insurance savings: $1,200 (30% on $4,000 wind premium)
- Payback period: ~2 years
- 20-year savings: $24,000 - $2,500 = $21,500 net benefit
This doesn't account for the avoided costs of storm damage repairs, which can easily exceed the insurance savings.
LDI Grant Program (Louisiana)
Louisiana's Department of Insurance (LDI) periodically offers grant funding to help homeowners offset the cost of FORTIFIED upgrades. When available, these grants can cover a significant portion of the upgrade cost.
Program Overview
The Louisiana Fortify Homes Program provides grants to help homeowners strengthen their roofs to FORTIFIED standards. Key details:
- Grant amounts — Typically up to $10,000 for roof retrofits
- Eligibility — Louisiana homeowners with owner-occupied primary residences
- Income requirements — Some grant rounds prioritize low-to-moderate income households
- Application — Online application through LDI when program is open
Combining with Insurance Savings
The real power comes from combining grant funding with insurance discounts:
- Grant covers upfront FORTIFIED upgrade cost
- Insurance discount provides ongoing annual savings
- Result: Net positive from year one
Program availability: The LDI grant program opens and closes based on legislative funding. Check the Louisiana Department of Insurance website for current program status, or ask us—we stay current on grant availability and can help you apply.
The FORTIFIED Certification Process
Getting FORTIFIED certification requires more than just installing the right materials—it requires third-party verification by an independent evaluator.
Step 1: Choose a FORTIFIED-Trained Contractor
Not all roofers understand FORTIFIED requirements. Look for contractors who:
- Have completed IBHS FORTIFIED training
- Have documented experience with FORTIFIED installations
- Can provide references from previous FORTIFIED projects
- Coordinate with FORTIFIED evaluators regularly
Step 2: Evaluator Pre-Inspection
Before installation begins, an IBHS-licensed FORTIFIED Evaluator inspects your existing roof to document conditions and confirm that FORTIFIED certification is achievable.
Step 3: Installation with Documentation
During installation, the contractor must photograph and document specific construction details that prove FORTIFIED standards were met. This includes:
- Sealed roof deck (before shingles installed)
- Nail pattern and spacing
- Drip edge installation
- Ridge cap fastening
- Attic ventilation
- All penetrations and flashing
Step 4: Final Evaluation
After installation, the FORTIFIED Evaluator returns to verify that all requirements were met. They review the photographic documentation and inspect the completed roof.
Step 5: Certification Issued
Once the evaluator confirms compliance, IBHS issues an official FORTIFIED designation certificate. This certificate is what you provide to your insurance company for the premium discount.
Timeline: For a typical roof replacement, the FORTIFIED certification process adds about 1-2 weeks to the overall project timeline.
Cost & ROI
FORTIFIED certification adds cost to a roof replacement, but the additional investment is typically modest compared to the benefits.
Additional Costs for FORTIFIED
The upgrade from a standard roof replacement to FORTIFIED Roof typically includes:
- Sealed roof deck materials — Self-adhering membrane or deck tape ($500-$1,500)
- Additional fasteners/nails — Enhanced nail pattern requires more nails ($100-$300)
- Evaluator fees — Pre-inspection and final evaluation ($400-$800)
- Additional labor — Extra time for documentation and precise installation ($500-$1,000)
- Total typical upgrade cost: $1,500-$3,500 beyond standard replacement
Return on Investment
In Louisiana, the math strongly favors FORTIFIED:
- Average upgrade cost: $2,500
- Average annual insurance savings: $1,000-$2,000
- Payback period: 1-3 years
- Certification duration: 5 years (renewable)
Over a roof's 25-30 year lifespan, FORTIFIED certification can provide $20,000-$50,000 in insurance savings alone—not counting avoided repair costs from storm damage.

Frequently Asked Questions
In Louisiana, absolutely yes. The mandatory insurance discount (20-52% on wind premium) typically pays for the FORTIFIED upgrade within 1-3 years, then provides ongoing savings for the life of the roof. Additionally, FORTIFIED roofs demonstrably perform better in hurricanes, potentially saving you thousands in repair costs. In Texas, the value depends on your specific insurance policy and whether your carrier offers FORTIFIED discounts—worth asking about.
A FORTIFIED Roof certification typically adds $1,500-$3,500 to the cost of a standard roof replacement. This includes upgraded materials (sealed roof deck, additional fasteners), evaluator fees ($400-$800), and additional labor for documentation and precise installation. The exact cost depends on roof size, complexity, and current condition.
FORTIFIED certification is valid for 5 years. To maintain your certification (and insurance discount), you'll need to have the roof re-evaluated before the certificate expires. Re-evaluation is simpler and less expensive than initial certification if no damage has occurred. If you've had repairs, those repairs need to meet FORTIFIED standards to maintain certification.
In most cases, no. FORTIFIED certification requires specific construction details that must be verified during installation—particularly the sealed roof deck, which is covered by shingles on an existing roof. The exception is if your existing roof was originally installed to FORTIFIED standards but never certified. A FORTIFIED evaluator can assess whether certification is possible.
A sealed roof deck is a secondary water barrier applied directly to the roof decking (plywood) before shingles are installed. It prevents water intrusion even if shingles are blown off during a hurricane. This can be achieved with self-adhering membrane (peel-and-stick), taped deck joints, or spray-applied sealant. The sealed deck is one of the most important FORTIFIED requirements.
Yes, Louisiana law (R.S. 22:1482) requires all property insurers to offer premium discounts for FORTIFIED-designated homes. The minimum discounts are set by law: 20% for FORTIFIED Roof, 35% for Silver, 45% for Gold. Individual insurers may offer higher discounts. You'll need to provide your official FORTIFIED certificate to receive the discount.
FORTIFIED Roof focuses solely on the roof system—sealed deck, enhanced fastening, proper edge details. FORTIFIED Silver adds opening protection (impact-rated windows/doors or hurricane shutters). FORTIFIED Gold adds structural connections throughout the home (roof-to-wall, wall-to-floor, floor-to-foundation). For most homeowners replacing their roof, FORTIFIED Roof is the practical choice.
No. Hurricane straps (metal connectors between roof trusses and wall plates) are just one component. FORTIFIED Roof certification doesn't require hurricane straps—that's a FORTIFIED Gold requirement. FORTIFIED Roof focuses on the roof covering and deck, not the structural connections beneath. However, hurricane straps are a good additional upgrade if you're doing major renovation work.
FORTIFIED Evaluators are licensed through IBHS. Your contractor should coordinate with an evaluator as part of the FORTIFIED installation process. If you need to find one independently, IBHS maintains a directory at fortifiedhome.org. In Louisiana, we work with several evaluators regularly and can coordinate the entire process.
Yes. FORTIFIED standards apply to all roofing materials, including metal. Standing seam metal actually meets or exceeds many FORTIFIED requirements by default (high wind rating, no exposed fasteners). The key additional requirements for metal roofs are proper edge detailing, sealed penetrations, and the documentation/evaluation process.
