What Are Those Black Streaks on my Roof?
Stains On The Roof?
The black stains on you roof shingles are caused by a black algae, typically called Gloeocapsa magma. Algae is more likely to grow on the shaded sections and the north side of the building.
Algae will spread from one infected roof to another via airborne spores. These spores land randomly on your roof and take root. A protective sheath creates the dark color the algae forms to protect its self from UV rays.
How Does It Grow?
Algae require moisture and the proper temperatures to grow on your roof. Dew is the primary moisture that causes algae to grow.
Algae are found predominantly in the Northeast, but it can and will grow nationwide. The algae generally grows on the northern exposures of your roof since this exposure generally receives less sunlight. Algae are well adapted to extreme climate conditions.
