Atlas Roofing Corp. announces Pristine Shingles featuring Scotchgard Protector from 3M. The shingles eliminate black stains and streaks caused by algae on roofing installed in high humidity areas. Since algae spores are airborne, nearly 80% of all homes in the US experience moderate to severe algae growth on their roof, causing aesthetic issues which are difficult to control.

“The Scotchgard Algae Resistant Roofing System is the single most effective algae solution available,” said Tim Worms, national accounts and marketing manager at the 3M Industrial Mineral Products Division.
