Commercial Steep Slope Systems

Malarkey's Windsor®, Legacy®, and hip and ridge shingles are manufactured with higher quality asphalt. The superior asphalt allows Malarkey to blend styrene-butadiene-styrene (SBS) polymers creating its unique Flexor™ SBS polymer modified asphalt technology. As the temperature fluctuates throughout the day, granules expand and contract.

Flexor™ SBS polymer modified asphalt technology allows for movement as the granules expand or contract with the change in temperature from hot to cold. The adhesive characteristics of Flexor™ SBS polymer modified asphalt technology perform as a superior fastener, holding the granules in place. Malarkey’s Flexor™ products are specifically manufactured to retain granules on the shingles, exceeding the ASTM granule retention test up to 75 percent. The adhesive and cohesive properties of shingles with Flexor™ are key to shingle longevity.

Windsor® and Legacy® shingles are UL 2218 Class 4 Impact Resistant and come with a 110 mph wind warranty. Malarkey also offers an Enhanced Wind Warranty to 130 mph (Windsor® 140 mph) when installation conditions are met.

Our Flexor™ SBS polymer modified asphalt shingles are available for a systems warranty, please contact our Technical Department at 800-545-1191 for more information.
