Every homeowner faces the never ending problem of bacterial growth accumulating on their roof. It starts out as a small patch that will go unnoticed at first.
However, 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 using our Certified Non-Pressure System.
