By choosing roofing shingles with Scotchgard™ Protector, your roof is protected against black streaks caused by algae for the life of the roof. Not only do we think they are the best roof shingles available to boost curb appeal, it’s also the only protector product DAAI Construction trusts. Once you see the beauty of your roof, free from black streaks, you’ll want to stand with 3M and DAAI Construction knowing Scotchgard™ Protector is the only algae-resistant roofing product for long-term protection against black streaks.

Can’t I Just Wash my Roof?
The black streaks found on asphalt roof shingles are commonly thought to be moss, mold or even fungus, but the truth is it’s most likely blue-green algae which takes the appearance of dingy black streaks. Pressure washing away algae is not an ideal solution. Not only will algae grow back becoming a recurring hassle and expense, but repeated roof cleaning may damage and decrease the longevity of your roof. A better solution is to prevent black streaks before they start by selecting shingles featuring Scotchgard™ Protector.
