They often appear in the form of black or dark green stains. This is probably caused by mold and algae that has found a home on your roof. The cost to rid yourself of these stains is not high and it may be worth it to get your roof looking like new again.
The northern and western sides of your roof are most prone to getting mold and fungus growth. Roofs get a lot of moisture on them in the morning. The dew settles on the roof.

The westerly side does not have sun reach it until the afternoon. That creates a damp, shady environment where mold and algae can grow. Therefore, sometimes we need to clean our roofs of this mess for aesthetics and to ensure the roof functions properly.
