What’s a FORTIFIED Roof?

FORTIFIED Roof™ (formerly FORTIFIED Bronze™) helps homes better withstand severe weather by keeping the roof on and keeping water out.

  • Improves roof sheathing attachment
  • Provides a sealed roof deck
  • Reduces chances of attic ventilation system failure (roof vents and gable end wall vents)

How’d We Do This?

Creating a Hurricane Inside the IBHS Research Center


Using data gathered during Hurricane Florence, our 105 fans provide realistic wind-driven rain conditions during a tropical storm.


We tested sealing the roof deck and how it can reduce the risk of wind-driven rain damage.

Moving the Building into the Chamber

Moving the building specimen into the large test chamber requires overcoming a good deal of logistical challenges.

Day of the Simulation

The calm before the storm. Final preparations are made the day of the simulation at the IBHS Research Center.
