Brian C. Jackson is a soft wash non pressure roof cleaning specialist and he uses an approved application to rid your roof of ugly black stains. The staining that is on the roofs in towns like Auburn, New Hampshire 03032 is called Gloeocapsa Magma and this is an algae that is feeding on the roof shingle. This algae needs to be cleaned off the roof or it will shorten the expected life of the roof and homeowners will be face with replacing a roof sooner than they thought. A roof cleaning should not be done with a pressure washer or a power washer and the ARMA (Asphalt Roofing Manufacturers Association) does not approve or recommend the use of a high powered machine. A safe non pressure method will not damage or dislodge any of the granules and it will not void the warranty on the roof.
