Impact Resistance Meets All-Weather Flexibility.
TruDefinition® Duration FLEX® Shingles are the only SBS polymer-modified shingle in the industry with patented SureNail® Technology — a combination that delivers UL 2218 Class 4 impact resistance alongside outstanding flexibility in all-weather installation conditions. The SBS (styrene-butadiene-styrene) polymer modification provides enhanced granule adhesion, improved tear strength, and superior performance in Colorado's freeze-thaw cycles and hail-prone seasons. Duration FLEX achieves 130 MPH wind resistance and lays flat faster than standard shingles, even in cold-weather installs.
