Roof Cleaning in Madison WI Using Safe Soft Wash Method

Black streaks on your roof are one of the most common and frequently misunderstood home exterior problems in Wisconsin. What looks like dirt or age-related staining is almost always Gloeocapsa magma a blue-green algae that feeds on the limestone filler in asphalt shingles. Professional soft-wash roof cleaning removes it safely without damaging your shingles or voiding your manufacturer roof warranty. We clean asphalt shingles as our most common roof cleaning job in Madison removing black algae streaks green moss growth and early lichen infestations from architectural and three-tab shingles. We also clean metal roofs with low-pressure cleaning and non-corrosive solution to remove oxidation algae growth and environmental staining without scratching metal panel coatings. Commercial and residential membrane flat roofs are cleaned with professional solution application followed by controlled low-pressure rinsing. High-pressure washing physically blasts away shingle granules which are the protective stone coating that gives asphalt shingles their weather resistance and rated lifespan. Removing granules voids most manufacturer warranties and accelerates shingle degradation by years of expected life. Soft washing uses chemical solution rather than mechanical pressure and is approved by the ARMA Asphalt Roofing Manufacturers Association as the correct safe cleaning method for asphalt shingles. Roof cleaning prices for Madison homes range from $250 to $320 for small roofs up to 1500 sq ft to $320 to $450 for medium roofs and $450 to $650 and up for large roofs above 2500 sq ft. Roofs above 7:12 pitch add 15 to 25 percent to base pricing. Soft-wash roof cleaning results typically last three to five years in the Madison climate with heavy tree cover sections possibly seeing algae return in two to three years.
