This slideshow on the represents a old worn shingle roof that is riddled with a dark discoloration from a common blue-green algae called Gloeocapsa magma. You have most likely seen this common blue-green algae discolor a majority of all shingle roofs over time and across the United States. To combat this discoloration, roofing shingle manufacturers add some asphalt granules impregnated with copper to fight discoloration of blue-green algae on your home’s roof.
