Homes are all susceptible to bacterial growth accumulating on their roof. It starts out as a small patch but, over time the spores spread and begin feeding off the organic material embedded within the shingles. The crushed limestone that is used as a weight additive during production is a natural food source for the bacteria. The most common growth appears as a "Black Streak" which leaves your roof looking UGLY! We can safely and effectively correct this common issue.
The use of the following equipment is not permitted. The shingle manufacturers only recommend "Soft-Wash" equipment when cleaning a roof. The use of any other equipment has been proven to damage the roofing materials and may void your existing shingle warranty. It is extremely important to ask what equipment will be used to clean your roof when getting an estimate. Please see our process to get a better understanding on how our system works.
