Soft Wash Cleaning for Commercial, Industrial & Residential

Roof Cleaning

The black stains on most roofs today is a blue-green algae named Gloeocapsa magma.  Roofing manufacturers reformulated asphalt shingles in the late 1980's, removing some asphalt and relacing it with crushed limestone.The limestone acts as a filler and gives weight to the shingle.

 

The limestone is the food source for the algae. On a North or East facing roof is where most of the growth occurs, combined with the growth of some black mold as well.  This orientation provides the ideal environment for each species to thrive, degrading the shingles.  The most recognizable and familiar black color is produced by the algae itself to provide it with protection from the UV rays of the sun.
