Removing Black Mold, Mildew Stains and Streaks From Roof Shingles

UPDATE: We no longer offer roof cleaning as one of our services.

After much research throughout the years on proper roof cleaning, Matthews’ Painting Company from Warsaw, Indiana now has a “No Wash No Scrub” roof and shingle cleaning system which cleans and removes black mold and mildew stains and streaks off of roof shingles.  This roof and shingle cleaning system also removes green mold and algae. It also works well on synthetic decking, such as Trex.  This application is all performed without the use of harsh chemicals such as bleach and acids, so it is safe for your roof, landscaping, and family. Household bleach can damage asphalt shingle due to its high sodium content. Apparently, the sodium causes an electrochemical reaction that reduces the elasticity of the asphalt leading to stiffness, brittleness and curling of the shingles.  Our process requires no pressure washing or scrubbing of the roof shingles.

Pressure washing roof shingles is not recommended.  Pressure washing or aggressively scrubbing mold and mildew off of roof shingles or roof tops reduces the shingle life by nearly 50% because it removes some of the gravel coating.  The gravel coating on an asphalt shingle serves as a UV inhibitor from the suns harmful rays, and serves as a fire retardant.  Pressure washing or “shampooing” an asphalt roof shingle, which require high pressure and/or scrubbing, will cause shingle damage to some degree.  Our roof cleaning system does not damage your shingles.
