What a FORTIFIED Roof Means for Texas Home Insurance

This guide explains what a FORTIFIED roof is, how it differs from an impact-resistant roof, and what the Texas Department of Insurance (TDI) has said about discounts for loss mitigation. It ends with the questions to ask a roofer and an insurer before you count on any credit.

The short answer

A FORTIFIED roof in Texas is one built or re-roofed to a voluntary wind-resistance standard from the Insurance Institute for Business & Home Safety (IBHS). TDI has encouraged, not required, Texas home insurers to offer actuarially supported discounts for standards like FORTIFIED. Whether any discount exists, and how large it is, is each insurer's decision.

TDI's Bulletin B-0008-26, dated September 16, 2026, puts it this way: "TDI encourages all property and casualty insurance companies operating in Texas to develop meaningful, actuarially supported premium discounts that allow homeowners who invest in loss mitigation to share in the financial benefits of the risk reduction they create."

That is encouragement, not a requirement. The bulletin gives no discount amount, and neither of the TDI pages cited here gives a figure for a FORTIFIED credit, so this guide gives none either.

What FORTIFIED is

FORTIFIED is a construction and re-roofing standard from IBHS, not a TDI program. As IBHS describes it, the standard focuses on strengthening homes against high wind and wind-driven rain.

IBHS describes three designation levels that build on each other: Roof, Silver and Gold. The work is documented by an independent evaluator, and the designation comes as a certificate that has to be renewed periodically, according to IBHS.

TDI's pages do not define FORTIFIED or set its requirements; the bulletin names it as an example of a resilient construction standard. For the requirements of each level and how renewal works, ask IBHS directly. For what a designation means for your own policy, ask your insurer.

A FORTIFIED roof is not the same as an impact-resistant roof

A FORTIFIED roof and an impact-resistant roof answer different questions: impact resistance is about how a roofing material stands up to impact in a laboratory test, while FORTIFIED is about how the whole roof system is built against wind and wind-driven rain. A roof can qualify for one without the other.

The impact-resistant column below draws on TDI's Products qualifying for impact-resistant roofing credits page (as of February 24, 2023). The FORTIFIED column draws on how IBHS describes its program.

For the Texas Windstorm Insurance Association (TWIA), the same TDI page sets out the test standard: "To be eligible for the credit, the roofing materials must have passed UL Standard 2218 and be classified as either Class 1, 2, 3, 4."

So a Class 4 shingle does not by itself make a roof FORTIFIED, and a FORTIFIED designation is not an impact-resistance class. If a roofer's sales pitch treats the two as the same thing, ask which one is being offered, what paperwork you will receive, and who issues it. Our guide on impact-resistant shingles in Texas covers the Class 1 to 4 system, the label and form PC068 in detail.

Where Texas stands as of October 2026

As of October 2026, TDI's position on FORTIFIED and other wind mitigation discounts is set out in Bulletin B-0008-26, which encourages insurers to develop such discounts without setting any amount. The bulletin is addressed to all property and casualty insurance companies writing residential property insurance in Texas.

The bulletin names the kinds of loss mitigation it has in mind, including building or retrofitting homes to "resilient construction standards like IBHS FORTIFIED Home™" as well as using impact-resistant roofing materials and proactively protecting against wildfire.

The bulletin also lists actions companies can take to recognize homeowners who have made loss mitigation investments. One is explicitly incorporating each loss mitigation item into rating plans. Another reads:

Informing policyholders of credits available for windstorm, wildfire, and other loss mitigation efforts.

A third is minimizing administrative burdens on consumers, such as making homeowners submit separate, redundant loss mitigation surveys or inspection forms along with any certificates or official designations. The bulletin also reminds insurance companies that want to introduce new discounts or expand existing loss mitigation credits to submit their filings through SERFF, the electronic system insurers use to file rates and forms with TDI.

The bulletin does not name a discount size, and it does not say any given insurer offers a FORTIFIED credit today. Treat it as a reason to ask your insurer, not as an answer.

What a FORTIFIED designation may be worth

Whether a FORTIFIED designation qualifies a Texas home for a premium credit, and for how much, depends on the insurer. Neither TDI page cited here publishes a FORTIFIED discount figure, so any number you see should come from your own insurer in writing.

That leaves two figures to collect yourself before you decide: what building to the standard would add to the cost of your roof, and what credit, if any, your own insurer confirms for it. A credit that one company gives may not carry over if you later move your policy to another company, so ask any company you are considering.

For impact-resistant roofing, TDI's roofing credits page says each class may bring a different credit and that each company sets the amount. That is a separate question from FORTIFIED, and a roof could qualify for one, both or neither, depending on how it is built and what each insurer accepts.

Steps to take before you re-roof

The practical window for a FORTIFIED roof in Texas is generally before a re-roof starts, because the designation covers how the roof is built. These steps can help you find out what a designation would mean for your home before you commit.

1. Ask before the work starts. If you are replacing the roof anyway, ask your roofer whether it can build to the FORTIFIED standard and how an independent evaluator would be involved. IBHS is the place to confirm the requirements for each level.
2. Ask your insurer which credits it actually offers. Ask your insurance company, or an agency that compares several companies, which mitigation credits it offers for homes in your area, what proof it wants, and whether it gives anything for FORTIFIED, impact-resistant roofing, or both. Do this before counting on any credit.
3. Keep every document. Keep the FORTIFIED certificate, any evaluator paperwork, the roofing product label and any installation form such as PC068. Note when the certificate needs to be renewed.
4. If you have TWIA coverage, ask TWIA too. TDI's roofing credits page says TWIA offers credits for impact-resistant roofing materials that meet its UL Standard 2218, label and form PC068 conditions. Ask TWIA what it accepts. Our guide on windstorm insurance and TWIA in Texas explains how that coverage works.
5. Send the paperwork once and confirm it was applied. After the work is done, send your documents to your agent or insurer and check your next declarations page or renewal for the credit you were told about.

• The same bulletin names building or retrofitting homes to resilient construction standards like IBHS FORTIFIED Home, using impact-resistant roofing materials, and proactively protecting against wildfire.

Take the next step

If a re-roof is coming, the two answers worth having in writing before the contract is signed are what building to the FORTIFIED standard would cost on your home and what credit, if any, your insurer gives for it. With both, you can weigh the cost against the credit yourself.
