1817 <br />HOW IT WORKS <br />Sunlight activates the smog-reducing granule with enough <br />energy to break apart water molecules in the air, like from <br />humidity (H2O breaks into OH and H). The newly formed OH <br />molecule seeks to attach itself to smog molecules (NO2 ) <br />that come close to the roof. <br />When the OH molecule attaches to the NO₂ smog molecule, <br />it chemically transforms NO₂ (smog gas) into NO₃ (a salt <br />solid) which drops to the roof and rinses away as plant food. <br />Smog is a form of air pollution resulting from the interaction of UV sunlight with chemicals in <br />the atmosphere like nitrogen dioxide (N02) that get into the air primarily from the burning of <br />fuel (ex. vehicle emissions). <br />SMOG-REDUCING GRANULES <br />All Malarkey shingles include 3M™ <br />Smog-Reducing Granules. Designed with <br />a photocatalytic coating, and blending <br />inconspicuously into the shingle’s color, <br />these innovative granules harness <br />sunlight to actively clean the air of <br />emission pollutants. Each average-sized <br />roof of Malarkey shingles (30 squares) <br />has the smog-fighting potential <br />equivalent to ~2 trees.2 <br />There’s more than one way to plant a tree. <br />ALGAE-RESISTANT GRANULES <br />Humidity and sunlight create the perfect environment for algae growth. On a roof, this growth <br />can manifest as black streaks that diminish your roof’s appearance. <br />Prevent black streaks caused by algae growth. <br />One Roof at a Time <br />“Granted, it’s just one roof, but if everyone starts <br />choosing a shingle that reduces landfill waste and <br />also fights air pollution, who knows what the end <br />result will be.” <br />– James Martinez, Homeowner <br />Why Not Just Clean the Roof? <br />Climbing on the roof and attempting to remove black <br />streaks caused by algae growth via pressure washing <br />is dangerous and can damage your roof by dislodging <br />the shingle’s protective granules, their primary defense <br />against damage and UV aging. <br />3M™ COPPER GRANULES (ALGAE) <br />To help combat algae growth, we utilize 3M™ Copper Granules. Designed with a special copper coating, <br />and blending inconspicuously into the shingle’s color, these innovative granules, on our AR (algae <br />resistant) designated shingles, release copper ions which inhibit algae growth, helping prevent it from <br />getting started in the first place. <br />MAXIMUM ALGAE PROTECTION <br />For maximum algae protection, shingles featuring Scotchgard™ Protector <br />utilize at least a 10% blend of 3M™ Copper Granules. <br />Malarkey was the first shingle manufacturer to receive the Scotchgard™ <br />Protector designation.
