FORTIFIED Commercial Roofing
Above Code. Built to Survive. Discount-Eligible.
IBHS FORTIFIED™ construction is the third-party-verified standard for above-code storm-resistant commercial roofing. Designed to address the most common roof failure modes in hurricane and tornado events — and eligible for premium insurance discounts of 5–25% across our markets.
What Is FORTIFIED?
The Standard for Commercial Storm Resistance
The IBHS FORTIFIED standard was developed to address the gap between minimum code compliance and actual storm performance. The Insurance Institute for Business & Home Safety (IBHS) is the research arm of the property insurance industry — they investigate actual building failures after major storms, identify what could have prevented them, and publish those findings as the FORTIFIED standard.
For commercial buildings in hurricane-prone and severe-weather markets, FORTIFIED construction provides a documented, verifiable standard that goes beyond what local building codes require. The standard targets the specific failure modes that cause catastrophic commercial roof losses: edge metal and perimeter pull-off, deck uplift, inadequate fastener density, and water intrusion through compromised coverings.
Critically, FORTIFIED designation is verified by an independent IBHS-trained evaluator after installation — not self-certified by the contractor. The standard is published, the inspection is third-party, and the resulting designation is recorded in the IBHS FORTIFIED registry. It's the most credible commercial storm-resistance credential in the industry.
The result is a roof system that performs measurably better when conditions are worst — and that qualifies for documented premium discounts from most commercial property insurance carriers in our coastal and storm-active markets.
Why Commercial Owners Choose FORTIFIED
Third-Party Verified
FORTIFIED designation requires an IBHS-trained evaluator to inspect installation against the published standard — not contractor self-certification. The verification is independent and the standard is published, making FORTIFIED the most credible commercial storm-resistance designation available.
Insurance Premium Discounts
Many commercial property carriers across LA, AR, MS, AL, FL, and TX offer 5–25% premium discounts for FORTIFIED-designated commercial roofs. The annual savings can offset the upgrade cost within 5–8 years on most commercial buildings — and the discount continues for the life of the roof.
Engineered for Real Failure Modes
FORTIFIED specifications target the most common commercial roof failures observed in hurricane and tornado events: edge metal pull-off, perimeter membrane failure, deck uplift, and inadequate fastener density. Every requirement traces back to documented post-storm engineering investigations.
Operational Continuity
A roof failure during a major storm event doesn't just damage the building — it interrupts operations, damages inventory, voids tenant relationships, and triggers extended business interruption claims. FORTIFIED roofs perform measurably better when the building most needs them to.
Documented Asset Value
FORTIFIED designation creates a permanent, third-party-verified record of construction quality. Useful for property transactions, financing, refinancing, and any due diligence process where storm-resistance documentation matters.
Carrier Specifications
Some commercial property carriers in coastal Louisiana and Florida now require FORTIFIED-level construction for full coverage on certain building types and locations. We help owners ensure carrier specifications are met during the re-roof process.
Compatible With All Membrane Types
FORTIFIED Commercial standards apply to TPO, PVC, EPDM, modified bitumen, metal, and steep-slope shingle systems. The standard isn't a specific membrane — it's a set of attachment, sealing, and edge-detailing requirements that any major commercial system can meet.
Local Code Plus
FORTIFIED is designed to exceed local building code requirements. In jurisdictions with strong wind codes (Florida HVHZ, Louisiana coastal), FORTIFIED is roughly equivalent. In jurisdictions with weaker baseline codes (much of LA, AR, KS, MS, TX inland), FORTIFIED represents a significant upgrade over code minimum.
What FORTIFIED Addresses
Edge & Perimeter Failure
The most common commercial roof failure in high-wind events. Wind uplift along the roof perimeter exceeds the field of the roof by 2–3x. FORTIFIED requires enhanced edge metal attachment, including continuous cleat anchoring and additional fastener density.
Deck Uplift
Sub-standard deck-to-framing fastening schedules can allow entire roof deck sections to lift away from the building during sustained high winds. FORTIFIED requires enhanced deck-to-framing fastener spacing throughout the field and additional density at perimeters.
Membrane Seam & Fastener Pull-Out
Mechanical attachment systems can fail at fastener heads if the attachment density isn't engineered for the building's wind zone. FORTIFIED requires FM Global-rated wind uplift specifications appropriate to the building's location.
Sealed Roof Deck
Even when the primary covering is damaged or removed, a properly sealed roof deck (using fully-adhered self-sealing underlayment or taped seams) prevents water from entering the building during the storm. This single specification often prevents the most catastrophic interior damage.
Insurance Discount Range
5–25% premium discount on commercial property insurance, depending on carrier, market, and FORTIFIED tier. Often offsets upgrade cost within 5–8 years.
Three Designations
FORTIFIED Roof, Silver, and Gold
Each FORTIFIED tier adds protection beyond the previous level. We help you select the right designation based on building type, exposure, and budget.
FORTIFIED Roof
The base FORTIFIED designation. Focuses entirely on the roof system: enhanced deck attachment, sealed roof deck, perimeter and edge specifications, and impact-resistant covering. The most common FORTIFIED specification for retrofits and re-roofs.
Best For
Existing buildings adding storm-resistance during a re-roof
FORTIFIED Silver
Builds on FORTIFIED Roof with additional protections: enhanced soffit and gable attachments, attic vents that resist water intrusion, and pressure-rated rooftop equipment. The right tier when the building owner wants meaningful upgrade beyond just the roof covering.
Best For
New construction or major renovations seeking measurable storm-resistance gains
FORTIFIED Gold
The highest FORTIFIED designation. Adds full continuous load-path detailing: structural connections from the foundation through the framing to the roof. Most commonly applied to new construction or substantial renovation.
Best For
New construction in hurricane zones; mission-critical commercial assets
Who It's For
When FORTIFIED Makes Sense
FORTIFIED Commercial is the right specification when storm exposure, insurance economics, or operational continuity are major considerations for the property. It's available across all our markets with FORTIFIED-trained evaluators on staff.

FORTIFIED Commercial FAQ
- FORTIFIED Commercial™ is an above-code construction standard published by the Insurance Institute for Business & Home Safety (IBHS). It specifies enhanced roofing requirements — including perimeter detailing, deck attachment, sealed underlayment, and fastener density — designed to withstand hurricane, tornado, hail, and high-wind events. Unlike basic code compliance, FORTIFIED designation is verified by a third-party IBHS-trained evaluator after installation.
- In most markets we serve, yes. Louisiana, Alabama, Mississippi, and many parts of Texas and Florida have commercial property insurance carriers that offer premium discounts of 5–25% for FORTIFIED-designated commercial roofs. The exact discount varies by carrier, building type, and zone. The annual savings often offset the upgrade cost within 5–8 years and continue for the life of the roof. We can help connect you with insurance brokers familiar with FORTIFIED discounts in your market.
- FORTIFIED Roof is the entry-level designation focused on the roof system — deck attachment, sealing, perimeter, covering. FORTIFIED Silver builds on Roof with enhanced soffit, vent, and rooftop equipment requirements. FORTIFIED Gold adds full continuous load-path detailing from foundation to roof. For most commercial re-roof projects on existing buildings, FORTIFIED Roof is the practical choice. Gold is most commonly applied during new construction or substantial renovation.
- Yes. FORTIFIED Roof designation is achievable during a routine re-roof on most commercial buildings. The work occurs naturally during tear-off and installation, with FORTIFIED-specific upgrades to deck attachment, sealing, edge metal, and perimeter detailing. The IBHS evaluator inspects during and after installation. Brown's Roofing has FORTIFIED-trained staff who can scope and execute FORTIFIED upgrades on commercial re-roof projects.
- FORTIFIED Roof typically adds 5–15% to a commercial re-roof project — for enhanced deck attachment, sealed underlayment, edge specifications, and the IBHS evaluator certification fee. FORTIFIED Silver adds another 5–10% for soffit, vent, and equipment upgrades. The actual premium depends on building size, base specification, and existing condition. We provide a comparison estimate (standard re-roof vs. FORTIFIED Roof) so you can evaluate the economics for your specific building.
- Yes. FORTIFIED specifications address tornado, hail, and severe straight-line wind events as well as hurricanes. In our Tornado Alley markets — Wichita, Little Rock, Shreveport, Lafayette, Monroe — FORTIFIED roof construction provides measurable performance gains in the spring and summer severe-weather seasons. Insurance discounts in inland markets are typically smaller than coastal markets but often still available.
- Yes. Brown's Roofing is an IBHS FORTIFIED-Certified contractor — we hold the contractor credentials required to scope, install, and document FORTIFIED Roof projects. The IBHS evaluator who issues the designation is required by IBHS to be an independent third party (not a contractor employee), so we coordinate the evaluator's mid-installation and post-installation inspections, supply the documentation they require, and stand behind the installation through the certification period.
