Gloeocapsa magma, a species of cyanobacteria, is the main bacteria responsible for the early failure of the shingles. The bacteria accumulate over time as it feeds on moisture and calcium carbonate, a common filler in the asphalt shingles. This accumulation begins to show the black stains as the cyanobacteria develop their dark and hard UV-protective outer coating.
The shingle manufacturers will void their warranties if they realize regular maintenance is not performed. Many people even lose their ability to get house insurance because of this issue, making it a tough battle with the mortgage companies. It also causes increased utility costs since a black stained roof draws in more heat.
