Tired of unsightly stains on your roof? Those ugly black streaks are caused by blue-green algae, which easily spread and multiply and can quickly diminish your home’s curb appeal.

While many algae-resistant shingles are on the market, only Atlas shingles featuring Scotchgard™ Protector by 3M come with a Lifetime Algae Resistance Limited Warranty against the black streaks caused by algae. Unlike competitors’ products, Atlas roof shingles with Scotchgard Protector have a minimum 10 percent blend of copper granules, which are the key to preventing algae growth.

Atlas Roofing shingles with Scotchgard Protector by 3M also carry the prestigious HOLMES Approved Product designation.

Scotchgard Protector is available in Atlas Roofing’s Pinnacle® Pristine, StormMaster® Shake, StormMaster® Slate and Legend® shingle lines.

Not sure which style would best complement your home? Check out the Atlas RoofSwap! app, where you can upload a photo of your roof to compare shingle colors and designs. Plus, the app’s Pristine Effect tool shows how Scotchgard Protector will keep your roof looking like new.
