Our Purpose
BlackStreaksOnRoof.com was created to help educate homeowners regarding roof algae. Cleaning over Replacement: When black streaks appear, industry standards (ARMA) recommend soft-washing or maintenance rather than full roof replacement.
Our goal is to provide a resource that explains the biology of Gloeocapsa magma, the engineering of asphalt shingles, and the approved methods required to fix the problem safely.
