Brian C. Jackson is a roof cleaner that cleans roofs that are covered with ugly black stains. This is an algae that is called gloeocapsa magma and it is not just a stain. This algae is feeding on the roof shingle and shortening the life span of the roof and if the roof is not cleaned the roof will fail prematurely and need to be replaced earlier than expected. The town of Brentwood, New Hampshire 03833 is having this same problem with gloeocapsa magma and it has homeowners wondering how to clean there roof. According to the ARMA (Asphalt Roofing Manufacturers Association) a roof should not be cleaned with a pressure washer or a power washer because of the damage a high powered machine can cause to the roof granules and dislodge them. The safe way to clean a roof is with a non-pressure / soft wash application and this will not damage the roof granules and will not void any warranty on the roof.
