Roof Algae
Brown or black roof stains are mainly caused by the growth of air-borne algae known as Gloeocapsa magma, they feed of the filled in composite shingles.  This algae thrives in humid climates and normally is first noticed on the northern facing portions of your roof where you will find the most shade and moisture content. As it rains, the algae is transported down the roof, giving the appearance of black streaks. Once the algae appears on your roof, it will continue to grow and spread until it is cleaned. The algae will never go away on its own, it will most likely only become even worse over time and lower the curb appeal. 
Why is Algae eating my roof ? 
Asphalt shingles are made with crushed limestone to give them weight and durability properties in order to protect your home against the elements. This limestone filler is used as the food source that algae need to survive. The algae will take root and feed on the limestone filler within the shingle dislodging the protective roof granules and exposing your roof to potential damage. A blackened stained roof is not only an eyesore, but a sign that you have algae literally eating it alive, taking years off its life.
Other Interesting Facts

Not only are the black roof stains unsightly, but it could affect your home in other ways too. The algae can prevent your roof from properly reflecting heat from the sun, potentially causing your homes heating and cooling costs to increase. Once your shingles lose their ability to reflect heat they also tend to deteriorate at an increased rate.

Roof Moss
Moss commonly thrives in environments that are damp and shaded. Moss absorbs the moisture from the damp environment and establishes roots on your roof causing the beginning of roof degradation. The roots can lift up shingles and constant moisture can lead to bacteria and mold growth. This eventually can lead to holes in your roof and leaks into your home. It is also dangerous to walk on a moss covered roof because it makes surfaces very slippery when wet. It’s very important to monitor for moss growth and treat as needed. If you live in an area that is frequently damp or in the woods, you should take steps to prevent moss growth on your roof. 

Roof Lichen ˈlīkən/
Roof Lichen are symbiotic organism where fungus and algae live in a dependent relationship, causing real damage to your roof. Lichen are are very difficult to remove, unlike the roof algae, roof lichen are persistent and deeply adhered to the roof. Some homeowners attempt to use harsh acids or cleaning chemicals to remove the lichen but even if these end up killing the lichen, the organism still remains deeply adhered to your roof. The only real way to remove lichen it the use of a pressure cleaning. Pressure cleaners take advantage of the hardness difference between the lichen (soft) and the tile (harder), everything other than tile is able to be removed.  Luckily lichen take years to develop and will not return for a long time after the roof has been effectively cleaned.
