Each component of a Malarkey roofing shingle plays an important role in protecting the home. The granules in polymer modified asphalt roofing shingles are no exception; they are specifically designed and engineered to preform specifically for certain climates. For instance, roofs in areas with prevalent moisture and humidity can experience algae growth in the form of black streaks on the roofing shingles. Algae growth on a roof can alter the color of your roof and make it appear aged.
Malarkey utilizes specialized granules that perform beyond traditional materials to offer benefits to the homeowner and the environment. Streak Resist™ Technology is a blend of algae resistant copper granules that help maintain the aesthetic appearance of your roof, and may reduce the need to clean your roof. By resisting black streaks caused by algae, the shingles retain their vibrant hues in concert with the rest of the home’s exterior.
Also available to protect homes from unwanted algae growth are Malarkey shingles featuring Scotchgard™ Protector from 3M™. These shingles similarly feature 3M™ Copper Roofing Granules. In 1994, Malarkey Roofing Products® became the first manufacturer to offer Scotchgard™ Protector in a shingle. Learn more about the history and scientific development of these granules in this video.
Granules offering algae defense, solar reflectivity, and color retention are all valuable contributions to the overall performance of the roofing shingle. To make sure these granules stay in place, Malarkey’s polymer modified asphalts such as Nexgen™ and Flexor™, are designed to respond positively to environmental temperature fluctuations.
