Unsightly black algae streaks may not be damaging your roof, but they are damaging your home’s property value and curb appeal. Algae spores are easily spread by the wind and thrive wherever moisture can be found, quickly taking over your roof. Homes in humid and hot areas or roofs that receive a lot of shade can face problems with moss (which can cause damage) and algae, especially their east facing sides. Dark-colored shingles are not a solution since algae streaks are visible on any shade of shingle. Pressure washing is also not a solution since it will only temporarily remove the algae while permanently removing some of your shingles’ granules, color, and UV protection.
Algae Resistant Shingles (ARS)
Algae resistant shingles (ARS) look like normal shingles to the naked eye but are manufactured to prevent algae growth. Because copper is proven to resist algae, most ARS shingles have copper granules strategically embedded along with normal granules to ensure the entire shingle roof is protected and maintains its uniform color and look.
Atlas Shingles featuring Scotchgard™ Protector
Almost every shingle manufacturer offers some type of ARS, but most only have a 3% – 5% blend of copper granules. Atlas shingles featuring Scotchgard™ Protector have a minimum 10% blend of uniformly distributed copper-containing granules among standard colored granules. These copper granules possess a proprietary 3M™ porous ceramic coating, which allows copper ions to release slowly over time, protecting your shingles from black streaks caused by algae. Available in different styles (slate-look or architectural) and a wide range of colors (from light to dark), Atlas shingles featuring Scotchgard™ Protector are manufactured using the best algae-resistant technology available. They will help maintain your roof’s aesthetic appearance by resisting the black streaks caused by algae, while simultaneously enhancing your home’s overall visual appeal. Atlas shingles designed with the power of Scotchgard™ Protector also have a Lifetime Algae Resistance Limited Warranty against the black streaks caused by algae. With an Atlas-shingled roof you will rest easy knowing that your beautiful shingled roof will maintain its original color, without washing (or any form of algae cleaning), year after year.
