Pressure washing a roof causes more harm than good

Many home owners are not aware of the proper way to clean a shingle roof.  Roof stains are a form of algae and need to be treated and eliminated with the proper cleaning solution.  There are some contractors that claim to use low pressure with a power washer, stating this is the best way to remove the unattractive stains.  Using pressure to clean a shingle roof can remove the granules that are on the surface of the shingles.  All shingle manufacturers recommend that you never use a pressure washer because it will void the warranty.

• Use a solution that will eliminate the algae spores
• Never use a pressure washer or any type of surface water cleaner
• Use cleaners approved by shingle manufacturers
• The proper cleaner will remove the stains without pressure

The picture below shows an attachment that hooks up to a pressure washer called a surface disk.  This is primarily used to clean concrete.  Clearly this method will damage the roof and remove the granules.  The algae spores are still alive because water alone will not eliminate it.

Removing roof stains and algae

Roof stains and algae that cover shingle roofs, tile roofs, cedar shake roofs and slate can be removed safely.  The black roof stains and algae that you see growing on your roof will break down the material and you the  home owner will have to replace the roof much sooner if not treated.  The stains are from the material in the shingle roof as well as the humidity.  The north side of a home gets less sunlight and with humid climates the algae and mildew will grow and feed off of the limestone filler in your shingles.  With cedar shake roofs and tile as well as slate the growth will still happen with humidity and less sunlight.  Treating the roof and removing the stains are recommended by all roofing manufacturers using the correct procedure and cleaning agents.  Never use a power washer to clean your roof or harsh chemicals.  Here at M&D we have been safely cleaning roofs and homes in Fort Wayne, Indiana and all surrounding counties.  Call or visit our website for more information.

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/
