Roof cleaning is the process to remove roof stains including Green Algae and Black Algae "gloeocapsa magma" from roofing materials in areas where high humidity is prevalent.

 

The black stains are also very likely to harbor a number of molds or fungi. Unlike algae, the fungi on our roofs lacks chlorophyll and are unable to manufacture food from raw materials. The algae must get nutrition from some form of organic matter. To thrive, they also require a warm, humid environment.

 

Fungi normally begin their life cycle as an airborne spore that settles on roofs. The spores on the northern exposure of the roof stand a better chance of survival because that portion of the roof is the last part to dry after a rain or morning dew. This raises the humidity on the surface of the shingle, thus creating a perfect feeding and breeding ground.

 

The tar used in roofing is fossilized, dead organic matter and an important food source for fungi. Asphalt, at the granule base, is normally consumed first. Once these granules dislodge, accelerated deterioration of the roof itself will occur. Ceramic granules represent the outer hard shell that protects against hail and other falling debris. Ceramic granules protect against damaging UV radiation and insulate the roof against extreme heat. So you can understand that their dislodgement by the growing fungal colonies can be detrimental to our roofs’ longevity. Surprisingly, the blue-green algae are also food for the fungi.

 

The Roof Cleaning business began becoming more common when the shingle manufactures changed from all asphalt to fiberglass shingles. The limestone in the fiberglass shingles which is added for weight attracts the bacteria and begins to spread. At times it can take up to 10 years before the Gloeocapsa Magma or "Black Streaks" become present.

 

There are many fiberglass shingle manufactures that now offer a Algae Resistant shingle; which comes with a 10 - 15 year warranty against growth. This type of shingle contains copper sulfate and is usually much more expensive than traditional shingles. However, most generally it takes that amount of time before the gloeocapsa magma shows up.

 

If the area of growth is left untreated the stains will spread causing more of an issue. Over time this bacteria will cause the material to possibly decay and result in premature failure.
