StreakGuard™ Algae Resistance Protection

When you go with Owens Corning TruDefinition® Duration® or TruDefinition® Duration® Designer shingles you get the added benefit of StreakGuard™ Algae Protection. It prevents black streaks from forming on your roof that can lower the value or curb appeal of your home. Owens Corning does this by blending copper-lined granules, which help prevent algae growth, into their colorful granules, which is proprietary to them, and is scientifically developed to meet the needs of specific regional climates. StreakGuard helps to inhibit the growth of blue-green algae and provides protection against black streaks.

Algae Growth & Black Streaks

Algae species are transported through the air and attach to shingles and other surfaces. When they attach to shingles and grow, they can cause brown and black streaks on the roof. While the streaks and algae growth is most common in humid regions, it can occur in all parts of the country. This growth does not impact the performance of the shingles, but can detract from the curb appeal. Owens Corning has advanced their algae resistance protection over 30 years, which helps to protect against the growth of blue-green algae.
