Alternatively, you can use asphalt roof cleaners.
2. Chlorine Bleach Roof Cleaning
Roof cleaners spray chemicals like trisodium phosphate with high concentrations of sodium hypochlorite. Once it dries up, it is reapplied as required.
The chemicals used in the process aren’t very expensive.
Also, the experts need not get on the roof for rinsing or inspection. So this method is quite affordable.

What’s more is that the fumes emanating from the cleaning agents may harm the pets and people. They are also harmful to the trees and plants and can damage them permanently.
Bleach may damage aluminum gutters. It also neutralizes termite protection chemicals.
Keep in mind that roof cleaners often conceal the fact that they use bleaching products for cleaning.
If they cover plants before cleaning the roof, then it is an indication that they are using bleach.
3. High-Pressure Power Washing
Some people prefer opting for high-pressure power washing.
This method uses hot or cold water for roof cleaning.
This cleaning method cleans the roof surface. But doesn’t get rid of the organisms completely.

How much does roof cleaning cost?
Roof cleaning costs depend on the slope, size, and design of your roof.
The more complex the design, the higher it will cost.

On an average, roof cleaning costs about $412.
If you live in a place which is prone to sleet or snow, then you may be charged higher.
