Chuck Bergman Soft Wash Roof Cleaning has been serving Charlotte and Sarasota Counties in Florida since 1991 { Prior to that as Chuck Bergman Pressure Cleaning }
With years of experience , it became clear to me that while pressure washing roofs made them look clean, damage was occurring on the roofs. Pressure cleaning machines can only be turned down so far and still accomplish roof cleaning and any amount of pressure, even as low a setting as 500 psi { 3000 to 4000 is what most pressure cleaning contractors use } will still remove around 15-20% of the granules that make up the color and protection of your shingle roof per cleaning.
Ugly black algae, left in place on the roof, eats around those granules and the rain removes them. Still eventually destroying the roof and spoiling it's appearance and resale value. With tile roofs, pressure removes the glazing many tile roofs come with. Pressure also blows pieces of cement that hold the ridge-caps in place off into space! If your tile roof is painted, pressure will blow portions of paint off all over the roof, leaving it in need of an expensive paint job!
So, what to do?
In 1991 I started developing a system to clean roofs without using pressure.
Now these roof cleaning systems are available for purchase commercially.
Even some of these "Non Pressure" systems are what I consider overkill, so I have tried them all and settled on what I consider the best for my customers. Some are designed to do a roof very quickly, using 7 gallon per minute {GPM} pumps on up! Others [because they are cheap] very slowly- 1 gpm pumps. I am in the middle and pleased with my results with pumps that essentially put out 3 gpm. I want the cleaning solution to remain on the roof, not to run off the roof or into the gutters.
In the attached link, you can read how a Roofing Manufacturers Association says to clean roofs. That is the only method I use. So your warranty will not be voided.
