Low Pressure Roof Cleaning

Caution! High Pressure washing should not be used on roofs!


Black Roof Stains.  Roof stains or discoloration is caused by a species of algae called Gloeocapsa Magma – sometimes called Black Algae or Roof Algae. This type of algae travels through the air or from falling debris and trees and collects on asphalt roofing and other materials.  This growth on your roof looks dirty and will reduce the life of your shingles as it begins to attach to the matting of the roof.

Roof Fungus.  As the fungus breaks down the asphalt shingle, the ceramic granules protecting the surface of the shingle are loosened. Once they begin to fall off it causes the roof to deteriorate and will diminish its ability to reflect heat. If not treated, the roof algae will reduce the life of your roof and increase your home cooling expenses.

OUR METHOD: Squeeky Clean uses low pressure roof cleaning equipment and specialized cleaning agents that are approved by the Asphalt Roofing Manufactures Association (ARMA Click to see technical bulletin) to eliminate algae, mildew stains, streaks, and dirt from shingles – all without damaging your roof.  The ARMA has recommended a process to clean asphalt roofing materials. Using this technique ensures that your warranty is not voided by improper cleaning chemicals and high pressure.

Is your roof is turning black? Airborne spores, that breed damaging fungal growth, eventually spread over your entire roof.  This fungus grows on asphalt shingle roofs, slate, cedar roofs, wood roofs, shake roofs, etc. To replace a roof costs thousands of dollars or more, Low pressure cleaning is a cost effective technique to cleaning the roof.  It’s safe, effective and a fraction of the cost to replace a roof.
