Thanks for checking out our blog. Here we journal our work in the local area so folks can see the dramatic results of a roof treatment. The black stains on this roof are caused by a bacteria called Gleocapsa Magma. This very hardy strand of bacteria develops an outer husk that repels UV rays. This is why this organism can live on the roof for long periods of time even if there is no rain. It is very contagious and spreads very easily from roof to roof. This is why one may noticed many houses on the same block may have some form of this type of staining. A shingle roof cannot be power washed. The shingle manufacturer recommends that no type of pressure at all be used for the treatment. Pressure washing a roof simply blows live mold spores all over the property. You may get a temporary reprieve from the staining, but it will surely return within a short period of time. Like any other pest, it needs to be eradicated 100%. By coating the roof completely with an anti-microbial detergent we can achieve this 100% kill ration. We use a biodegradable solution that when used properly is 100% safe for all landscape and pets. Your roof is probably one of the most expensive items of a home. Checking for credentials is paramount when seeking a professional roof cleaning contractor. Always checks for a NJ state contractors license. The State of NJ is very strict when issuing license and thoroughly checks that all insurances are in place. Other resources to use are the Better Business Bureau, Google and Yahoo reviews, Judysbook reviews, and Angieslist.
