Scotchgard™ Vs. Competitors
Unlike our competitors' "algae-resistant" shingles, Atlas shingles featuring 3M™ Scotchgard™ Protector contain a minimum 10% blend of 3M™ copper-containing granules that prevent unsightly algae stains on a roof.
In this special edition of Hammer Time With Paul, we show you why StormMaster® Shake and Pinnacle® Pristine shingle lines carry a true lifetime warranty against the ugly black streaks caused by algae.
