Standard pressure washing can destroys a roof because of the high PSI. It may appear to have cleaned your roof or home exterior, but it only attacks algae, mold and mildew growth at the surface. Though the stains are gone, the roots remain, and the stains grow back thicker and blacker, usually within 6 months!
The streaks that are staining the roof are actually a bacteria called Gloeocapsa Magma. This is the main culprit for most of the roof staining in Michigan. Moss and Lichens also grow where destructive growth has been started by the fungal growths. They will eat and destroy wood, deteriorate roofing materials and make your roof retain heat (raising cooling costs). Simply put, these pests are costing you money!
These infestations no only damage your roof, they affect your home’s appearance, which can lower your property value or even get your homeowners insurance cancelled.
The good news is that these stains (micro organisms) can be safely removed. Our Soft Wash method and cleaning solutions are safe for your roofing material, and results are amazing.
