FORTIFIED Roofs and Texas Home Insurance: TDI's Push for Discounts, Explained for Fort Worth Homeowners

Fort Worth homeowners replace roofs the way other people replace tires. Hail is a fact of life in Tarrant County, and after the adjuster leaves, the same question comes up every spring: is there a roof that actually lowers my insurance bill?

In 2026, Texas regulators gave that question a sharper answer. Here is what the FORTIFIED standard is, what the state did and did not do, and how to make sure you get paid for the roof you buy.

What Is a FORTIFIED Roof?

FORTIFIED is a program of the Insurance Institute for Business & Home Safety (IBHS), an independent 501(c)(3) nonprofit research organization supported by property insurers and reinsurers. fortifiedhome.org describes it as "a voluntary construction and re-roofing Program designed to strengthen homes and commercial buildings against specific types of severe weather such as high winds, hail, hurricanes and even tornadoes," and says more than 100,000 families have chosen it.

There are three residential levels, and every one starts with the roof: "a FORTIFIED Roof is required for every level of FORTIFIED designation." Per fortifiedhome.org, a FORTIFIED Roof requires:

• A sealed roof deck. If wind strips the shingles, the plywood underneath is exposed and water pours through the seams. "FORTIFIED requires roof decks to be sealed to prevent this type of water damage."
• Ring-shank nails in an enhanced pattern. "Instead of common smooth nails, FORTIFIED requires ring-shank nails, installed in an enhanced pattern, to help keep the roof deck attached to your home in high winds."
• Locked-down edges. The standard calls for "a wider drip edge and a fully adhered starter strip," because roofs usually begin failing at the edge.
• Wind- and rain-resistant attic vents and chimneys anchored to the structure.

FORTIFIED Silver adds pressure-rated (and in hurricane-prone areas, impact-rated) windows and doors, wind-rated garage doors, gable end and chimney bracing, and anchored porches and carports. FORTIFIED Gold adds "an engineered continuous load path" tying roof to walls to foundation. For most Fort Worth re-roofs, the conversation is about FORTIFIED Roof.

How Is FORTIFIED Different From a Class 4 Shingle?

Most homeowners (and more than a few roofers) blur this. A Class 4 rating belongs to the shingle. A FORTIFIED designation belongs to the roof system, and a third party verifies it.

IBHS is pointed about the difference. Its hail page notes that "many homeowners choose Class 4 impact-resistant (IR) shingles. Yet, years of research by the Insurance Institute for Business & Home Safety (IBHS) show many IR shingles do not perform as expected in real-world storms." IBHS buys shingles "just like the consumer—from local suppliers," tests them with lab-made hail, and scores dents, tears, and granule loss from Poor to Excellent.

For hail country, FORTIFIED offers a Hail Supplement. A shingle roof seeking it "must use a product with an overall score of 'Excellent' or 'Good' on the IBHS Roof Shingle Hail Impact Ratings." Those products, the roof page says, "outperform typical Class 4 shingles when tested against realistic hailstones and will better protect your home from hail up to 2" in diameter."

What Did TDI Do on September 16, 2026?

First, TDI issued Commissioner's Bulletin B-0008-26, addressed to "all property and casualty insurance companies writing residential property insurance in Texas." It "encourages all property and casualty insurance companies operating in Texas to develop meaningful, actuarially supported premium discounts" for loss mitigation, and names the examples: "building or retrofitting homes to resilient construction standards like IBHS FORTIFIED Home™, using impact-resistant roofing materials, and proactively protecting against wildfire."

It asks insurers to build each mitigation item into their rating plans, tell policyholders which credits exist, and minimize administrative burdens "such as forcing homeowners to submit separate, redundant loss mitigation surveys." New or expanded discounts must be filed through SERFF, the state rate-filing system.

Second, in its news release the same day, TDI went further: "TDI also recommends changes to state laws that would require insurance companies to consider whether a homeowner has taken steps to protect their home from wind, hail, and wildfire damage when setting rates. The next legislative session begins in January." Commissioner Amanda Crawford put it this way: "Texans who invest in reducing risk should see the benefit of those investments reflected in what they pay for insurance."

Note the verb. The bulletin encourages; it does not set a percentage, even though the Governor's office describes it as having "directed insurers to account for a home's FORTIFIED roof status in rate setting so premiums reflect the lower risk." The number on your policy is still the company's to file.

Where Did This Come From? The Governor's August Directive

On August 24, 2026, Governor Greg Abbott sent Commissioner Crawford a two-page letter. Its first directive: "Require insurers to include a home's FORTIFIED roof status in their rate setting calculation to reduce the cost of insurance premiums." It also told TDI to prohibit refusing to write or renew based on the age of the property "including individual components such as the age of the roof."

The letter's framing is cost: "the average annual homeowner's insurance premium in Texas has increased 79 percent in six years, from under $2,000 in 2020 to over $3,500 in 2026." The Governor has also proposed a Texas Roof Fortification Program "to reduce wind and hail damage" for the next session.

TDI's September 14 response gives the regulator's reasoning in one line: "Texas law requires that insurance price should be correlated to the risk of each property. If a company is not considering mitigation in setting rates, there is opportunity to better align with that standard." It also floated a homeowner mitigation grant program for the Legislature to consider.

Why Does Texas Care So Much About Roofs?

Because roofs are where the money goes. TDI's Texas homeowners insurance market overview breaks paid losses out by peril. For 2024, Texas homeowners insurers paid roughly $4,933 million for hail and $2,210 million for wind, against $1,611 million for water and freeze, $1,092 million for fire, and $362 million for everything else. By our arithmetic, wind and hail were about 70 percent of paid homeowners losses that year. TDI's preliminary 2025 figures show the same shape: about $2,324 million for hail and $757 million for wind, again the two largest perils by a wide margin.

If you live anywhere in Tarrant County, that chart is your neighborhood. It is why most Texas policies carry a percentage wind and hail deductible instead of a flat dollar amount, and why roof age and material drive so much of what you pay for home insurance in Fort Worth. The roof is the one lever a homeowner actually controls.

Should You Upgrade to FORTIFIED When You Replace a Hail-Damaged Roof?

The best moment to go FORTIFIED is the moment you are already paying for a roof. The FORTIFIED FAQ says that "when re-roofing a 2,000-square-foot home, the cost increase is typically between $1,000 and $3,000." Your claim will generally pay for a like-kind roof, so ask the roofer to break the upgrade out as a separate line. Then run through these questions:

• Is the roofer a certified FORTIFIED Roofing Contractor? The FAQ states that each FORTIFIED roof "must be installed by a certified FORTIFIED Roofing Contractor." Search the directory at fortifiedproviders.com.
• Who is the evaluator? Per fortifiedhome.org, "FORTIFIED Evaluators are independent, third-party contractors who have been trained in the FORTIFIED program requirements." Hire one before tear-off, since the deck sealing and nailing get covered by shingles.
• Are you getting the Hail Supplement? In North Texas, this is the point. Confirm the shingle's IBHS hail rating is Good or Excellent, not just "Class 4."
• How does your policy settle roof claims? If it pays roofs at actual cash value, a new roof changes your position at the next claim. Read ACV versus replacement cost on roof claims first.

How Do You Document a FORTIFIED Roof for Insurance?

The process produces one piece of paper that matters: the designation certificate. According to fortifiedhome.org, "throughout the construction or reroofing process, your evaluator will be collecting documentation that key elements of the FORTIFIED standard are being met." IBHS reviews that file, and "when IBHS completes its review and determines a home meets the FORTIFIED standard it will send a designation certificate to the evaluator, who will then deliver it to you."

Keep the certificate, the roofer's invoice, and the shingle documentation together, and note the date: "Initial FORTIFIED designation certificates expire five years from the date they were issued." Insurers that discount FORTIFIED homes often "require the designation to be renewed every 5 years."

How Do You Ask Every Carrier for the Credit?

TDI's own consumer tip is blunt: "Ask your company if you're getting all the discounts you qualify for," and "don't forget to tell your company if you make major renovations." A new roof qualifies. The practical version:

1. Send the certificate to your current carrier and ask, in writing, which roof credits apply: FORTIFIED, impact-resistant roofing, roof age, or anything else. Ask for the new premium.
2. Do not stop there. Bulletin B-0008-26 encourages discounts; it does not standardize them. One company may file a FORTIFIED credit, another may only credit impact-resistant shingles, and a third may price roof age so heavily that the designation barely moves the number.
3. Have the finished roof quoted across carriers. This is where an independent agent earns the role. We take one set of facts (certificate, shingle rating, roof date) and price identical coverage across 22+ carriers so you can see what each one actually gives you for it. A captive agent can only show you one company's filing.
4. Watch the wind and hail deductible, not just the premium. Two similar premiums can carry very different percentage deductibles, and the cheaper one may cost you thousands more at the next hail claim.

What Happens Next in Austin?

Three threads to watch: whether carriers answer the bulletin with new SERFF filings; TDI's proposed rule barring refusals to write or renew based on the age of components such as the roof, which matters if your carrier has been non-renewing older roofs; and the January session, with TDI's mitigation recommendation and the Governor's Roof Fortification Program on the table.

None of that changes what to do this fall. Our practice is simple: we review every renewal and re-shop when an increase is out of line, and a new FORTIFIED roof is exactly the kind of change that justifies a fresh look. See also what switching from a captive carrier looks like and what to do when a renewal jumps. Hail is not only a Texas story, either: our St. Charles office hears the same roof questions from Kane County homeowners, and the documentation advice applies to Illinois home insurance too, though the TDI bulletin itself is Texas-only.

The Bottom Line

Texas just told its insurers, in writing, that stronger roofs should cost less to insure, but not how much less. For a Fort Worth homeowner, that means the FORTIFIED upgrade is worth pricing when you are already buying a roof, the certificate is worth guarding, and the credit is worth shopping, because it will not be the same at every carrier.
