If you are concerned with the effects of weather on your roof, this is the shingle for you.

TruDefinition™ Duration STORM™ Impact Resistant Shingles with WeatherGuard® Technology are the perfect shingle choice for inclimate weather conditions. Unlike standard shingles, these shingles feature an integrated polymeric backing material that allows the shingle to met one of the industry's highest ratings for impact resistance, UL2218, Class 4. Underwriters Laboratories (UL) has one of the most demanding standards for testing the impact resistance of shingles. Their test determines the amount of stress a newly manufactured roofing shingle can withstand without cracking and then rates the shingle's performance. TruDefinition Duration STORM shingles have achieved the highest rating possible - Class 4.

The test uses 4 different sized steel balls to simulate the force of free-falling hailstones. To test the impact resistance, the shingles are struck twice in the same spot. A class rating is then assigned to signify resistance to a particular size steel ball - the higher the class rating, the greater the resistance.

In addition to having a best-in-class rating, the Storm Shingles are also easier to install and handle than other UL 2218 rated shingles. They resist scuffing and marking during hot weather installations and they will not fuse together in the bundle or on the rooftop during high temperature conditions.

If that isn't enough, this shingle is made with the SureNail Technology that features a tough, woven engineered reinforcing fabric to deliver consistent fastening during installation. Triple Layer Protection™ , a unique 'triple layer' of reinforcement occurs when the fabric overlays the common bond of the shingle laminate layers that offers excellent fastener holding power. Superior adhesion thanks to the Tru-Bond® sealant grips tightly to the engineered fabric nailing strip on the shingle below. With excellent adhesive power that has been specially formulated, the wide adhesive band helps keep the shingle layers laminated together. The industry's first asphalt roofing shingle engineered to deliver 130-MPH wind warranty performance with only 4 nails.
