Why Algae Grows on Your Roof
The primary reason for roof algae in Central Michigan is moisture. You’ll usually see these streaks on the north-facing side of the house or areas heavily shaded by trees. In Mt. Pleasant, Alma, Midland, and Clare, our humid summers provide the perfect “petri dish” for these spores to land and spread across your roofline. As the algae grows, it creates a dark pigment to protect itself from UV rays, which is what causes the visible black staining on your home.
The Danger of Pressure Washing
The biggest mistake people make with roof algae in Central Michigan is using a high-pressure washer. Shingles are covered in ceramic granules that protect the asphalt from the sun. Pressure washing blasts these granules off, effectively “aging” your roof by 10 years in a single afternoon. Professional contractors use a “soft wash” method, applying a specialized cleaning solution that kills the algae at the root without the need for damaging pressure.

Improving Airflow and Sunlight
Sometimes, simple maintenance can help manage roof algae in Central Michigan. Trimming back overhanging tree branches allows more sunlight to reach the roof and improves airflow.
