This shingled roof had a lot of living, black algae. It is specifically Gloeocapsa Magma, a true bacteria, but so commonly referred to as algae, I call it algae too. The roofing manufacturers, having paid money out for years, on roof warranties, unnecessarily, due to wear and tear from pressure washing machines, developed a chemical cleaning method, which does not incorporate pressure as a means of complete algae removal. Once all algae is eradicated, almost all roofs look just about like new. An average pressure washer machine will run from 3000 to 4500 psi [ pounds per square inch ]
The roofing manufacturer's chemical cleaning method, usually called Soft Washing, or non-pressure or no pressure cleaning, utilizes a 60 psi pump, only to deliver the roof cleaning mixture up onto the roof. Why blast the granules off of your shingles and flip the tabs unnecessarily? You may also void your roof's warranty. Call Chuck Bergman Soft-Wash Roof Cleaning and Pressure Washing.
