What are those dark stains on my roof?
The discoloration on your roof is caused by harmful bacteria (gleoocapsa magma is probably the most prevalent of several algae) feeding on your roofing surface, specifically the limestone found in asphalt shingles. Ultimately decomposing your roof and giving an unsightly curb appeal.
The longer and darker the streaks, the more damage to your roof. This erosion and granular loss on the shingle cause it to weaken, discolor, harden, and crack. The ending result is a shorter life span for your roof, including:
Higher Utility Bills
Bacteria cauase your roof to absorb heat, making your home work harder and cost more money to cool..
Unsightly Curb Appeal
Ugly roof stains cometically bring down the appeal and value of your property.
Bacteria create an increase in allergic reactions for people who are sensitive to these types of bacteria.
Lesser Life Span of Roof and Need for Replacement
Mildew, algae and lichens feed on organic material and can grow on any surface. When they feed, they break down the material, which decomposes and needs replacement sooner.
Insurance Companies Can Even Drop Your Coverage
Insurance companies have been reported to warn and even drop coverage for roofs that are extremely dirty. Don’t put your family at risk!
What is SOFT WASHING
Soft washing is a cleaning method using low pressure and specialized solutions to safely remove mildew, bacteria and other organic stains from roofs and other building exteriors.
It is so named to differentiate the method from power/pressure washing. The Asphalt Roofing Manufacturers Association recommends low pressure bleach or detergent assisted washing as the preferred method for cleaning asphalt roofs in order to prevent damage to the shingles.
