Cleaning Mixtures Methods and Equipment We only use cleaning ingredients approved by ARMA*, the Asphalt RoofingManufacturers Association.These cleaning agents are blended specifically for the conditions prevalent on each individual roof and pose no harm to the roof shingles. Our mixtures provide the proper amount of cleaning power to effectively remove all mold, mildew, and streaks. The cleaning agents are carefully applied in a consistency which allows the solution to stay in contact with the roof shingles as the algae, mold and mildew are neutralized. After the solution biodegrades and evaporates from the roof, the dried crystals and surfactant act as a roof treatment to keep the roof cleaner longer. No pressure of any kind is used in the entire roof cleaning process. Pressure washing is never recommended because it will remove a large amount of the ceramic coated granules from your shingles, which may void the warranty. Pressure washing equipment is not used. The lowest possible pressure settings pose significant risk of damage to the shingles. Our equipment has been assembled specifically for safe and effective roof cleaning. |
