Here in West Michigan you’ve probably seen unsightly black streaks
on asphalt shingle roofs
. Some people think this is caused by an accumulation of dirt, mold or mildew, or defective shingles. The culprit that is actually causing the black streaks is a blue-green algae
known as Gloeocapsa Magma. This type of algae is spread by airborne spores. A roof alga, commonly known as Gloeocapsa Magma, is a type of algae that thrives in humid and warm climates and usually appears first on the North side of the roof where shade is prevalent and moisture tends to accumulate. Our weather patterns, and the humidity we have in West Michigan is a prime growing habitat for this algae also. The result is usually a black streaked roof. Roof algae, once attached to a shingled roof, feeds on the limestone used in the manufacturing process of the shingles. As the fungus breaks down the asphalt shingle, the ceramic granules protecting the surface of the shingle are loosened and begin to fall off. This causes the roof to deteriorate prematurely and diminishes the roof’s abilities to reflect heat rays. If not treated, the roof algae will reduce the life of your roof, diminish your home’s curb appeal and increase your home cooling expenses.
