Brian C. Jackson is a roof cleaner that specializes in cleaning the ugly black stains off of the roofs through out Massachusetts, New Hampshire, and southern Maine. The staining that homeowners are seeing on there roofs in Dracut, Massachusetts 01824 is an algae called gloeocapsa magma. This algae is not good for the roof and it needs to be cleaned or the algae will shorted the life of the roof shingle and the roof will need to be replaced earlier than expected. The ARMA (Asphalt Roofing Manufactures Association) approves and recommends a roof cleaning that is done with a non-pressure / soft wash application because the use of a pressure washer or a power washer will damage the roof. The use of a high pressure machine will dislodge the roof granules and scare the roof and it may even void the warranty on the roof. For more information on a non-pressure roof cleaning or any of the other exterior soft washing services, visit www.jacksoncontracting.net or call Brian @ (603)401-8408,
