You may have noticed dark stains forming on your roof. It’s not an uncommon sight here in the Chicagoland area. Drive around your neighborhood and look at some roofs and you are sure to see a few with dark streaky stains on them. Some people believe this to be mold, but the more like culprit is the pervasive Gloecapsa Magma algae. 

In this article: Black Roof Stains? Check for Algae, Kelsey Savage, a writer for BobVila.com, explains more about this common roof problem and how to deal with it.  She explains that although this algae mostly just presents a problem with the appearance of your roof, it can lead to premature aging of the shingles. 

If you are preparing to install a new roof on your home, you may want to consider having copper or zinc strips added along the upper ridge of your roof to prevent this problem from reoccurring. Before hiring any contractor to work on your home, however, it pays to shop around and be judicious with your selection.
