What Malarkey Shingles Are Made Of
Most asphalt shingles use oxidized asphalt, which stiffens and gets brittle as it ages. Malarkey blends its asphalt with rubber and plastic polymers, a formula it calls NEX® Rubberized Asphalt. The rubberized core flexes instead of cracking, holds its granules longer, and resists tearing. Malarkey rates its shingles at up to 35–40% greater tear strength and 65% greater granule adhesion than the ASTM D3462 industry standard.
Part of those polymers come from upcycled tires and plastic bags. On an average 30-square roof, that adds up to the equivalent of roughly 4 to 7 tires and 2,900 to 7,100 plastic bags kept out of the landfill, depending on the shingle line.
The surface uses ceramic-coated 3M™ roofing granules for lasting color, plus 3M™ smog-reducing granules that use sunlight to break down nitrogen dioxide from vehicle exhaust. Malarkey says each average roof offsets smog about as much as planting two trees. Algae-resistant versions add 3M™ copper granules to fight the black streaks that show up on Northwest roofs.
