A FORTIFIED roof is built to a stronger standard than an ordinary roof, and in a hail-and-wind market like Dallas that difference is the whole point. FORTIFIED is a construction standard developed by the Insurance Institute for Business & Home Safety (IBHS) after decades of real-world storm research, and Arrington Roofing is FORTIFIED-trained — a member of our team has passed the FORTIFIED Wise roofing contractor exam (the IBHS contractor training program), and Arrington is listed in the FORTIFIED contractor directory. The standard started in the hurricane states and is now moving into Texas, where our spring hail and straight-line winds put roofs under the same kind of stress. This page explains what a FORTIFIED roof actually involves, what its designation levels mean, why it matters for a Dallas home, how the verification step works, and how it can lower your insurance premium.

What Is a FORTIFIED Roof?

FORTIFIED is a voluntary, engineered building standard — not a product or a brand of shingle. IBHS designed it around the three things that most often fail on a roof during a severe storm: the edges lift, the deck attachment gives way, and water gets in once the covering is gone. A FORTIFIED roof addresses each of those failure points with stronger fastening, a sealed roof deck that acts as a second line of defense, and reinforced edges. The result is a roof engineered to stay on the house and keep water out when an ordinary roof would not. A peer-reviewed 2025 study found that homes with a FORTIFIED roof had 73% fewer insurance claims and 72% lower losses than standard-construction homes — the kind of measured difference that explains why insurers reward it.

What Are the FORTIFIED Designation Levels?

One point worth clearing up: a FORTIFIED designation belongs to a home, not to a contractor. IBHS awards three levels, each building on the one before it, and which one fits a house depends largely on whether it's an existing roof or new construction.

FORTIFIED Roof (base level)

The foundation of every FORTIFIED home, focused on preventing water intrusion and keeping the roof system attached during high wind through a sealed, locked-down roof deck and reinforced edges. It can be applied to an existing house during a reroof, which is why this is the level most Dallas homeowners will pursue — and the one Arrington works with most.

FORTIFIED Silver

Includes every FORTIFIED Roof requirement, plus structural upgrades to windows, doors, and gable ends so wind-driven rain and debris can't enter through the openings. Reaching Silver on an existing home can require reinforcement or reconstruction at those openings.

FORTIFIED Gold

The highest level. It builds on Silver by creating a continuous load path that ties the roof, walls, and foundation together so the whole structure resists high winds as a single unit. Gold is best achieved on new construction, because doing it after the fact means opening up walls. There is no Platinum level at this time.

For the great majority of Dallas reroofs, FORTIFIED Roof is the practical and achievable designation, and it's where Arrington concentrates its FORTIFIED work.

How Is a FORTIFIED Roof Built Differently?

In the video at the top of this page, Arrington owner Chris Arrington walks through an actual FORTIFIED installation point by point — the clearest way to see what separates it from a standard reroof, and the same process our crews follow on every FORTIFIED job. Below, we break down the specific upgrades that define the build, each one targeting a known failure point.

1. Tighter Deck Fastening

On a standard roof, the decking is fastened with nails spaced eight to twelve inches apart. A FORTIFIED roof tightens that to four inches, using ring-shank nails whose ridged shafts grip the wood far harder than smooth nails and resist pulling loose under uplift. The deck is what everything else attaches to, so anchoring it more securely strengthens the entire system from the bottom up.

2. A Sealed Roof Deck (the Secondary Water Barrier)

This is the upgrade homeowners tend to find most reassuring. Before any underlayment goes down, the seams where the decking panels meet are covered with an adhesive-backed sealing tape, applied across the roof in a checkerboard pattern. If a storm ever strips the shingles off entirely, that sealed deck keeps water from pouring into the house — the difference between a damaged roof and a flooded home. It is the single feature that most defines a FORTIFIED roof.

3. Reinforced Edges and Flashing

Roof edges are where wind gets its first grip, so they get extra attention. The metal drip edge is set with a minimum two-inch overlap onto the deck and nailed every four inches in a staggered pattern for a stronger hold, rather than the wider spacing used on a standard roof. Ice-and-water shield — the peel-and-stick membrane we'd normally reserve for valleys and around penetrations — is run around the full perimeter as well, sealing the most vulnerable edges.

4. Stronger Shingles, Nailed for Uplift

The covering itself has to meet the standard. A FORTIFIED asphalt roof uses at least a laminated (architectural) shingle rated for 130 mph winds, and each shingle is hand-nailed with six nails instead of the typical four. Because the nail line on each course also passes through the shingle below it, every shingle effectively ends up secured by twelve nails — a meaningful gain in resistance when wind is trying to peel the roof back.

Every one of these upgrades goes beyond ordinary building code. Sealed deck seams, increased attachment of the deck to the structure, increased attachment of the underlayment to the deck, and increased attachment of the drip edge and shingles at the edges are all requirements code does not impose. For homeowners who also want hail protection, the FORTIFIED system can be upgraded to meet the Hail Supplement, which calls for a Class 4 (impact-rated) shingle — the most relevant upgrade in a hail market like Dallas.

Why Does a FORTIFIED Roof Matter for a Dallas Home?

North Texas sits in one of the most active hail corridors in the country, and the spring 2026 season was a reminder of why — the late-April outbreak alone brought several days of severe storms and large hail across the metroplex. A standard roof is built to shed weather; a FORTIFIED roof is engineered to survive the worst of it and protect what's underneath even in a failure. For a Dallas homeowner weighing a roof replacement, especially after hail damage or storm damage, building back to the FORTIFIED standard turns a forced expense into a lasting upgrade rather than a like-for-like replacement that will face the same storms with the same vulnerabilities.

IBHS frames the homeowner payoff in three plain terms. You stay dry — a FORTIFIED home helps protect the structure and what's inside from high winds and wind-driven rain. You get back home quicker — by limiting water intrusion when a roof is damaged, FORTIFIED can reduce or eliminate the time a family spends displaced. And you may save money — a FORTIFIED designation may qualify for an annual wind mitigation credit that lowers your premium, though that depends on your specific policy and carrier.

The Verification Step: How a Home Earns Its FORTIFIED Certificate

This is the part homeowners most often miss. Building to the FORTIFIED standard is necessary but not sufficient on its own — the home only earns its official designation after an independent, IBHS-approved FORTIFIED evaluator verifies the work and documents it, which is what generates the certificate. That certificate is what you hand your insurer to claim a wind mitigation credit. In practice it means the build has to be done correctly and documented at the right stages (the sealed deck, for example, has to be photographed before the underlayment covers it). We build to the standard and coordinate the documentation an evaluator needs so the verification goes smoothly and you actually end up with the certificate in hand. Getting this part right is what protects both payoffs — the insurance wind-mitigation credit and any grant funding — because a skipped step or an undocumented stage can cost you eligibility for either, even on a sound roof. We photograph each required phase and work directly with the evaluator so nothing falls through the cracks.

Can a FORTIFIED Roof Lower My Insurance and Help with Cost?

Often, yes — though insurance and grant help work very differently, and it's worth being clear-eyed about both. On insurance: because a FORTIFIED roof is proven to reduce storm losses, many Texas insurers offer a discount on the wind-and-hail portion of your premium for a home that earns an official FORTIFIED designation. How much varies by carrier, so check with your agent for the specific wind-mitigation credit available on your policy. On cost help: the Federal Home Loan Bank of Dallas runs a FORTIFIED Fund that can offset the cost of building to the standard — but it's important to understand what this grant is and isn't. It is not automatic and not unlimited. For 2026 the fund offers up to $17,000 per household to replace an existing roof to the FORTIFIED standard, for homeowners at or below 120% of the area median income; a second round of funding opened July 1, 2026 and runs through December 31 or until the money is claimed, whichever comes first, on a first-come, first-served basis. The grant is never paid to you as cash — the fund works only through a participating member bank or credit union, which passes the money through as a grant for the roof itself. It also carries conditions with real teeth: the contractor must hold the required IBHS FORTIFIED credential, the roof must use approved materials and methods, an independent third-party evaluator must verify and document each phase, and the home has to earn its FORTIFIED certificate. Skip a step or miss a required photo and the funding can be delayed or denied even on a well-built roof — which is why it has to be planned from the start rather than "backed into" afterward. And because the grant offsets the cost rather than eliminating it, and not every roofer can offer it, who you work with matters.

Arrington's FORTIFIED Credentials

FORTIFIED is still new to Texas, and Arrington moved early to be ready for it. Our team member James Townsend has completed the 2025 FORTIFIED Standard Roofing Contractor Exam through FORTIFIED Wise, the contractor training program run by IBHS, earning that credential on February 19, 2026 (valid for three years) — his certificate is shown on his team profile. Arrington is also listed in the FORTIFIED contractor directory. As additional team members complete their FORTIFIED training, we'll add them here. This training is what backs our ability to build correctly to the standard — the formal FORTIFIED designation itself is always awarded to your home by an independent evaluator, as described above.
