Let's face it...you are tired of seeing them. Yes, I am talking about those ugly roof stains. Are the roofs in your complex covered with black streaks & stains? If so, then you may be surprised by what the staining you see actually is. It is a form of algae called "Gloeocapsa Magma" which feeds on crushed limestone used in common asphalt shingles. The good news is it can be removed using the right roof cleaners and cleaning technique. Many people don't realize what causes the stains on your roof. We have heard almost everything...from residue of jet fuel to the shingles rotting from the insideout.
The truth is shingle roofs are manufactured with different degrees of quality. Most roofs applied by builders and roofing contractors are in the low quality to at most mid quality range with few, if any, fungus fighting elements like zinc or copper.
