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, homeowners are encouraged to opt for the Hail Supplement to their FORTIFIED designation. To achieve this added level of protection, shingles must score Good or Excellent on the IBHS Hail Impact Ratings. These outperform typical Class 4 shingles when tested against realistic hailstones and will better protect your home from hail up to 2” in diameter.
