Brian C. Jackson is a roof cleaning specialist and he specializes in cleaning the ugly black stains off of the roofing shingle. This black staining is call gloeocapsa magma and it is an algae that is not just a cosmetic stain. This algae will shorten the life of the roof if it is not cleaned and this will lead to replacing the roof earlier than expected. Towns like Atkinson, New Hampshire 03811 has this same problem and the homeowners are wondering what is the best way to clean there roof. The ARMA (Asphalt Roofing Manufactures Association) approves our safe non-pressure roof cleaning application and does not want the use of a power washer or a pressure washer. A high powered machine can cause damage to the roof granules and dislodge them which is harmful to the roof and can also void the warranty on the roof.
