More than Dirt

Gloeocapsa magma is a type of algae that grow abundantly on roofs. Also called GM, these algae can feed off the limestone and asphalt roofing materials in certain shady, cool and moist conditions. When there is very little light, the algae may be bluish-green in some areas. The side of the roof that is more suited to the cultivation of Gm will be more noticeable and can begin to produce molds as well. This can explain why there is often only one side affected.


Lichens are like a mixture between algae and a fungus and that{s exactly what it is.  Asphalt Roofing Manufacturers describes lichens as a symbiotic relationship between the fungus and algae. These organisms will spread their roots deep into the organic oil-based components of the roofing shingles for its nourishment.

But, moss is probably the most detrimental problem with roofing shingles. Moss gets in between the tightly laid shingles and materials and causes them to lift away and curl back. This is because of the amounts of moisture contained in the moss reacting to the temperatures outside.
