Roof stains

Many people are not aware that you can clean a shingle roof.  The black roof stains that you see are a form of algae that is growing on the roof mainly on the north side because it lacks the majority of sunlight.  Humidity also makes the algae worse because it creates moisture and the algae grows more and feeds off of the limestone filler that is in the shingles.  Treating and cleaning your shingle roof is very important because you want it cleaned the correct way without the damage of a pressure washer.  Shingle manufacturers agree that cleaning your roof and eliminating the algae spores will promote the life of your roof.  As time goes on without treatment the stains will get worse and the algae will continue to spread and grow damaging your roof.  Here at M&D power washing we use a chemical treatment that is lightly sprayed on the roofs surface removing the stains and eliminating the algae spores for up to 3 years.  Same day results the black stains will be gone.  Serving Fort Wayne, Indiana and all of Allen county.  260-413-3290 http://www.cleantheroof.com/
