What is Non-Pessure Roof Cleaning?
Thank you for taking the time to read ur blog. We journal these before and after pics to show the dramatic results of how soft-washing roofs and siding can increase the value and curb appeal of a home. Soft-washing is the use of low pressure and detergents to acquire the level of clean you see in the pictures. We never perform high pressure power washing on any surfaces. High pressure can blow off siding, damage roof, scar wood or Trex decking, and etch concrete. There are specifics detergents for each application. After the detergent is applied a low pressure rinse can follow to finish the job.
What are those black stains on my roof?
Black streaks on a roof are a bacteria that feeds on the limestone in the roofing shingle. This form of bacteria are able to digest limestone and will never go away. They will always multiply and only get worse. They grow more on the northern exposures of the roof where the sun shines less. These areas retain more moisture and allows the bacteria to grow faster. Pressure washing a roof shingle does not kill the bacteria. Treating the stain like”pest control” is the only way to insure the stain will ot return for any considerable length of time.
We answer a lot of phone calls from people looking to clean mold or moss from their roof.
Soft-Washing is the new technology for cleaning
The pressure of a motorized pressure washer can be altered by increasing the size of the nozzles on the wand. Since water output of a pressure washer is constant, the pressure can be lowered by increasing the nozzle size. It can also be increased by using a small orifice nozzle. Since the machine always discharges the same gallans per minute, putting on a smaller orifice nozzle forces the machine to discharge that water through a smaller hole which in turn increases the pressure. The concept is very similar to a garden hose. An open hose with no spray has the least pressure. Once you screw on a spraying attachment and cause a restriction, it forces the water through a smaller hole, there for it can now shoot 10, 20, or maybe 30 feet in some instances.
