I was reading about that stuff before i started my business 2 years ago. its junk, it just wont do the job. the right method is here. I have talked to roofing manufactures and some say no pressure and others say you can use it but try to keep the pressure low. If you see it taking off the granulars its too much so just back off. I have talked to others and some say broom off any moss if you want. The funny thing was they all said moss and lichen or black algae goes not cause any dammage. kinda funny i thought
