Many roofs throughout the greater Grand Rapids area are infested with black streaks, moss and lichen. We have safely cleaned 100's of roofs with our certified soft wash system. We have cleaned all types of roofs, from asphalt, cedar, tile and metal. While there are reasons to use a pressure washer to clean some surfaces, cleaning a roof should never be done with a pressure washer. With our soft wash cleaning, we gaurantee the roof will stay clean for 2 years. We do more than just power wash off the stains like a pressure washer does. We kill the growth on the roof, and leave a biocide on the roof that makes it a hostile environment for the algea and bacteria that causes the black streaks. If you have a dirty roof in the greater Grand Rapids area, or anywhere in West Michigan, give Kleen a call. We can help.
