Brian C. Jackson cleans roofs all over New Hampshire , Massachusetts, and Southern Maine that are covered with ugly black stains. This staining is an algae and it is called Gloeocapsa Magma and it is not just a cosmetic stain. This algae is harmful to your roof and it is feeding on the roof shingle and shortening the expected life of the roof. If the roof is not cleaned it will fail earlier than expected and need to be replaced and a replacement will cost a lot more than a roof cleaning. Homes in the town of Stratham, New Hampshire 03885 have this same problem with the black staining and has homeowners wondering how to clean there roofs. A safe non pressure / soft wash method is approved and recommended by the ARMA (Asphalt Roofing Manufacturers Association) and a pressure washer or power washer should never be used to clean a roof.
