Most roof stains are caused by the growth of algae, lichen colonies or moss that feed on organic matter frequently found on roof surfaces. The portions of a roof that receive the least amount of sunlight are more likely to have roof stains. This explains why some homes may have roof stains only on one side of the roof, typically the northern and/or western exposure or in heavily shaded areas.

No. Our products will not harm any vegetation or surfaces around your home.
NEVER! High pressure powerwashing can be very damaging to the shingles. Plus, it's not effective.
It's impossible to tell how long it will take for a new roof to get algae stains, the same holds true for a roof cleaned using the Roof Shampoo™ system. We give our customers a written warranty against any roof staining for a period of one year. We also offer an annual roof maintenance program.
Yes. Once we do a Roof Shampoo™ we can return once a year to apply a special spray on/leave on Roof Shampoo™ stain prevention treatment. Every consecutive year that you participate in the program extends your warranty for an additional year.
Yes, but the results can be disastrous. Bleach can damage vegetation and dry out your shingles. Any results that the homeowner sees are temporary and the staining is back within a few short months.
Algae is a living, growing organism which left untreated, can cover your entire roof. A roof covered in algae absorbs heat and results in a superheated attic, raising cooling costs. Since algae feeds off the organic material in your shingles, left untreated, your roof will require costly, premature replacement.
