What is Soft Wash Roof Cleaning?

Soft wash roof cleaning is a specialized cleaning method that utilizes low-pressure water combined with professional-grade cleaning solutions. This approach is designed to effectively kill and remove organic growth like moss, algae, lichen, and black streaks from your roof without causing any damage to the shingles.

Unlike traditional high-pressure washing, which can strip essential granules from asphalt shingles, void manufacturer warranties, and significantly shorten your roof's lifespan, soft washing targets the root cause of the growth. The gentle yet effective cleaning solutions break down these organisms at their source, ensuring a more thorough and longer-lasting clean.
