Now more than ever, we need the
security of a FORTIFIED Roof™.

Give your family extra protection from severe weather.

Severe thunderstorms can bring dangerous tornadoes, powerful straight-line winds, and damaging hail. Your roof is your home’s first line of defense against the weather.

When you replace your roof, have your roofer follow the FORTIFIED Roof standard.

To fight back against strong winds, FORTIFIED Roof seals the seams between your roof’s wood decking to keep rain out, adds stronger nails, and locks down the edges. The system is topped with a high-performance shingle that safeguards the integrity of your roof against hail.

How do you get a FORTIFIED Roof?


The FORTIFIED Roof standard is grounded in the best science and engineering knowledge from two decades of research and testing by the Insurance Institute for Business & Home Safety. FORTIFIED gives your roof system extra protection above what local building standards provide.

You can find FORTIFIED roofers in your area by searching the FORTIFIED directory. FORTIFIED roofers have been trained on FORTIFIED roof requirements.

Roofs built to FORTIFIED Home™–High Wind & Hail requirements feature upgrades like IBHS-rated impact-resistant shingles that improve your home’s durability and lower cost of ownership compared to standard roofs. Roofer will work with an independent 3rd party to ensure that FORTIFIED-approved materials are used and installed on your new roof.

Homes with FORTIFIED roof designations under FORTIFIED Home™–High Wind & Hail are eligible for wind and hail premium discounts in Oklahoma and elsewhere.


Your roof is more than just shingles.
