When severe weather strikes, a FORTIFIED Roof keeps the wind and rain out, preventing a cascade of damage that can destroy your home and belongings. FORTIFIED Roof was specifically designed to prevent damage that commonly occurs during high winds, hurricanes, hailstorms, severe thunderstorms, and even tornadoes up to EF-2. No matter what type of roof you have—shingles, metal, or tile—the following FORTIFIED Roof requirements will make your home stronger.
Roof damage often begins when wind gets underneath the roof edge and begins ripping it away from the home. To help protect this vulnerable area, FORTIFIED requires specific materials and installation methods, including a wider drip edge and a fully adhered starter strip, that when used together create a stronger system.
If wind rips off your roof covering―such as shingles, metal panels or tiles―it exposes the wood beneath and allows water to pass through the gaps and enter your home. FORTIFIED requires roof decks to be sealed to prevent this type of water damage.
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. In fact, using ring-shank nails nearly doubles the strength of your roof against the forces of winds.
In hail-prone areas, FORTIFIED requires shingles tested by IBHS to show they can withstand hail up to 2 inches in diameter. These shingles outperform typical Class 4 shingles when tested against realistic hailstones and will better protect your home.
Danny Lipford, host of Today’s Homeowners, explains the benefits of FORTIFIED and why he chose to follow the standard when building his own house.
