Commonly mistaken as mold or mildew, the blackish discoloration you see is actually algae. The most common type, blue green algae, produces a dark pigment to protect itself 
from UV rays. Discoloration happens in stages, first showing up as small spots but rapidly morphes into streaks. Algae can form wherever moisture dwells on a roofs surface and is most commonly found in costal and humid areas. It is easily transferred from one roof to another by the wind or animals and typically appears on many roofs in the same neighborhood.
Algae Removal
This mold should be removed by a professional roof cleaner with the appropriate cleaning solutions and tools. It is not advised for homeowners to clean their roof themselves.
