The ugly, dark stains that are so prevalent are caused by a very hardy “blue-green” algae, Gloeocapsa magma, that thrives on the asphalt shingled roofs in much of the country, especially in the highly humid areas. These areas most likely to be impacted by stain causing roof algae, Gloeocapsa magma, as well as other stains caused by mildew, mold, moss and lichen.

Growth is more prevalent on the north and west facing surfaces of the roof (and highly shaded areas) due to the reduced amount of sun received by these surfaces. After a rain, these roof surfaces tend to not dry completely thus providing an ideal area for algae growth. As algae grows on the roof, it holds even more moisture which accelerates the growth. The results is ugly roof stains that continue to get worse and worse over time .

It is bad enough that algae causes ugly roof stains, unfortunately it also damages the roof. The algae takes root on the shingles dislodging the granules which protect & color the roof. It holds water to the roof's surface and can cause decay & rot of the roof's underlayment. Not only is your roof being discolored by the algae, but it is shortening the life of the roof leading to earlier than necessary roof replacement.
