Algae Armorβ„’

Is your home in a humid or wet area? Algae thrive in environments with high levels of moisture. Some algae can cause unattractive black streaks to grow on a roof over time, which can alter the color of your roof and make it look older than it is. To ensure that the roof installed today preserves it beauty, choose a roofing shingle that defends against algae.

Streak Resist Technology

Streak Resist™ Technology

Shingles with a blend of copper roofing granules resist algae growth and help maintain the aesthetic appearance of your roof. The copper roofing granules are designed to slowly release copper ions which resist algae growth and prevent black streaks from appearing on the roofing shingles. The copper ions gradually disperse over an extended period, depending on the concentration of the granules in the shingle. Therefore, Malarkey offers 5, 10 and 12 years of protection against algae with Streak Resist™ roofing shingles.
