Brian C. Jackson is a non pressure / soft wash roof cleaning specialist and he specializes in cleaning the black ugly stains off of the roofs through out New Hampshire, Massachusetts and southern Maine. This staining is called gloeocapsa magma and it is an algae that feeds on the roof shingle and will shorten the life of the roof. It is important that homeowners know the proper way to have a roof cleaned and that the method used to clean the roof is approved and recommended by the ARMA (Asphalt Roofing Manufacturers Association). There are homes all over Exeter, New Hampshire 03833 that have this algae on the roofs and it needs to be cleaned or the roofs will be replaced earlier than expected. A roof should never be cleaned with a high powered machine like a pressure washer or power washer because the use of a machine like this can void the warranty and damage the roof shingle by dislodging the roof granules.
