Roof cleaning advice

I’m planning to clean my own roof as I have noticed there’s a bit of black staining appearing, along with the start of moss along the edges of the tiles.
Roof cleaning isn’t something I have ever done so any advice is appreciated.
My plan of action is to add an old brush with 50 degree red fan jets to my gardiner pole and run it along the tiles top to bottom. First spray of hypo (2:1) to get rid of the staining, let it work and then rinse off, once dry same process with benz (not sure of dilution ratio) to get rid of the moss.
Is this acceptable process? Also what surfactant would be best?
