At the bottom of this page are a few before and after garden variety roof cleanings in Old Bridge NJ. Not every before and after pictures gives dramatic results and some of it may get lost in translation. There are black algae stains growing on the homes of this culdesac. This type of staining is caused by a type of bacteria which can feed on the limestone in the roofing shingle. Limestone is an organinc mineral comprised of crushed skeletal remains of marine life. This bacteria can digest the limestone and excretes an acidic by-product that assists in loosening the roofing granules.
Why are roofing granules so important?
Those little gritty roof granules is what protects the underlying membrane of the shingle. The granules can be of all different colors to give each home its unique curb appeal. Roofing granules protect the membrane from outside elements, especially UV rays which are most damaging to the shingle. If you’ve ever stuck your hand in a gutter you may have noticed some of these granules inside. This is the amount that comes off with rain and wind. So imagine what any type of pressure washing could do to a roof. We never use any type of power washing on a roofing shingle. We use a NON-pressure roof cleaning system which utilizes a foaming roof detergent. This detergent is comprises of 4 parts: Salt, chorination, a surfactant (foam), and water. Since we approach the stain like “pest control” we are seeking a 100% kill ratio. This method is opposed to pressure washing which only blasts live mold spores everywhere plus dislodges large amounts of roofing granules. Never let anyone use any type of pressure washing device on your roof. Any roof shingle manufacturer can substantiate this suggestion.
