Algae often thrives on asphalt shingles because one of their key ingredients is limestone. The limestone is composed primarily of calcium carbonate, which is what the algae feeds on. Paired with moisture from rain or humidity the perfect living environment for algae is created.
That is why CS Roofing Company has a solution for roof algae problems. We use CopperCat Algae Terminator to help eliminate moss, eliminate algae and eliminate mold.
