Jessica from Marlboro, NJ has been a Green Sun Energy Services client since May of 2026. We soft washed the two-storey house at the end of that month, using a sodium hypochlorite and surfactant solution at low pressure. On a roof this is the only method worth using: the dark streaks that show up on shingles are algae rather than dirt, and the granules that give a shingle its working life sit loosely enough that pressure takes them off along with the growth. Shingle manufacturers specify low-pressure cleaning for precisely that reason. The solution does the work instead, and the roof keeps the surface it was built with.
Amazing work - John and his team were excellent and our backyard looks new again. Highly recommend!
