How to Clean Your Roof with Roof Wash
Use Roof Wash to remove stains caused by moss, black algae, mold, lichen or any fungus that may grow on roofs. It's highly effective on all types of roofing material: asphalt, metal, tile, wood shake, rubber and new composite materials. Note: we do have some roof cleaning products made specifically for other types of roofing like "Cedar Wash" for Cedar Shake Roofs and "Tile Roof Wash" for all types of cement and clay barrel tile roofing.
If you are afraid of spraying a chemical up on your roof you should be. Not only can the chemical run off and damage your plants and lawn, but some roof cleaning products sold online can be fatal to your pets. These toxic chemicals can alter the color of your roof and stain any other surface it may contact on the way off the roof. Our roof cleaner, "Roof Wash" is made from earth friendly hydrogen peroxide and it will not harm people, pets or property. As an oxygen based cleaner, the product only has an active life of 4-6 short hours before this product biodegrades, making it by far the safest product in the roof cleaning industry.
Roof cleaning can be accomplished two ways, 1. The roof can be physically washed with light pressure or 2. Mother Nature can do the rinsing. Roof cleaning contractors go up on the roof and physically wash the roof down. There is always a natural concern from the home owner about someone pressure washing their roof, a pressure wand in inexperienced hands can cause serious problems to a roof but a pressure washer in experienced hands will result the highest quality, longest lasting “clean” available. After applying the Roof Wash the correct method is to be up on the roof using light pressure aiming down the roof at all times at the angle of the roof, this way there is never direct pressure with the roof. The pressure washer in this fashion is just being used to rinse the roof down, sending all the waste and debris into the gutters. There are also special nozzles for pressure washers that we manufacture called “Soft Tips” that would further reduce the impact pressure on a roof by up to 70%. When a roof is professionally cleaned this way, no damage occurs to the roof.
Most home owners do not have the capability of cleaning their roof the way a contractor would so most choose method number 2 and let Mother Nature help out. Nothing will ever get a roof as clean as when it is physically washed down with a pressure washer, but this method will get the roof pretty darn close, let's say 85-90% cleaner. To do this, apply the solution to the roof and let it dry, then apply one more coat and leave the roof for Mother Nature to wash. Timing an approaching works well too. A repeat application may be necessary after a number of rainstorms if the roof isn't as clean as you would like it but you can clearly see the roof get cleaner and cleaner after every storm, it will continue to clean itself for months and months after the application.
