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 polymers creating its unique polymer modified asphalt technology. As the temperature fluctuates throughout the day, granules expand and contract.

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 polymer modified asphalt technology perform as a superior fastener, holding the granules in place. Malarkey’s 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 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.
