Soft Washing

Soft washing is a cleaning method using low pressure and specialized solutions to safely remove mildew, bacteria, algae and other organic stains from roofs and other building exteriors.
It is so named to differentiate the method from power washing. The Asphalt Roofing Manufacturers Association recommends low-pressure washing as the preferred method for cleaning asphalt roofs in order to prevent damage to the shingles.

Soft washing is using an electric agricultural sprayer to apply a water-based, biodegradable disinfecting cleaning solution to kill the mold, mildew, bacteria, algae, fungus, moss and more on exterior home and building surfaces. Gloeocapsa Magma (algae) is common on roofs and often leaves signature black streaks all over your shingles. This substance thrives in humidity and hot temperatures and spreads out, having a destructive effect on your roof. It feeds off the moisture that certain types of shingles hold on to. While the roof is effected, it begins to lose its ability to reflect UV rays and eventually rots the shingles. This has been said to effect roofs severely and can take up to 10 years off the life of a roof. Soft washing is the only way to effectly remove this algae without damaging the shingles and voiding any warranty.
