Professional contractor and TV host Mike Holmes values the trusted brand of 3M. That's why he designated Atlas shingles with Scotchgard™ Protector a HOLMES Approved Product.

Scotchgard Protector prevents the ugly black streaks caused by algae, keeping roofs looking newer longer.

"Spending your money right the first time is the most important thing that homeowners need to understand," Holmes said during the 2019 International Roofing Expo. "Buying the right shingle to cover your home, from the right company, having it properly installed — you save money. Longevity, aesthetics, resale, no leaks."
