Brian C. Jackson is a roof cleaner that has the task of ridding your roof of the ugly black stains. This staining is because of an algae called gloeocapsa magma and this algae is not just a cosmetic stain. This algae will shorten the life of the roof shingle if it is left alone to just feed on the roof shingle. Cleaning the roof is more cost effective than replacing it and when done properly with the right application there will be no damage done to the roof. Nashua , New Hampshire 03060-03064 has thousand of roof that are in need of a roof cleaning and the ARMA (Asphalt Roofing Manufacturers Association) dose not approve or recommend the use of a pressure washer or a power washer. The proper way to clean a roof is with a non-pressure / soft wash application that will not damage the roof or the roofing granules. The use of a high pressure machine can and will damage the roofing and dislodge the granules from the shingle and may void the warranty on the roofing.
