This homeowner in Newburgh, NY reached out to us in need for a full roof cleaning.

What is the Klaus Roofing Way roof cleaning process? We use a soft wash cleaning method, which means that we do not power wash! Power washing will remove granules from roofing shingles, significantly reducing the life of the roof. Our goal is to extend the life of the roof by removing harmful organic growth from roofing shingles. We begin by protecting your home's landscape. We then apply our roof cleaning solution made up of household cleaners and surfactants. This solution immediately starts to work as it kills mold, mildew, algae, moss, or any other organic growth on the roof's surface. Our solution is then left on the roof surface to ensure all organic growth has been killed down to the roots, meaning it's gone for good.

From there, we simply let mother nature take its course. Over the next 14 days, the rainwater will naturally rinse off all dead organic matter that was killed off during our soft wash process.

Bill in Highland, NY, reached out to us after noticing black streaks and small patches of green growth on his roof. While the roof itself was in good condition, it needed a professional cleaning to restore its appearance. We performed a roof cleaning using our soft washing method, which uses low-pressure spraying and specialized cleaning solutions to safely remove algae, moss, and stains. This process is gentle on roofing materials, helping maintain the roof’s integrity and keeping it looking fresh and clean. The Klaus Roofing Way!
