Will a fatboy bandit(or any other roof pump) kill serious moss?

I live in western Washington where all the roofs are covered in moss. will the right mix of bleach and surfactants kill resilient moss and be able to be sprayed off the same day? Is it worth getting for moss removal or just for the algae on roofs?

Electric can kill moss, but most of us in the PNW use Air pumps for volume and reach with the steeper roofs we have. And you will be able to rinse the same day but plan on still having Rhyzomes left. Of the customer needs it all gone, then either pre-treat and return, or plan on a follow up rinse down.

Ok thank you! I am up in the air if I’m going to even attempt it any time soon. My little 5x10 trailer is packed full of powerwash stuff and I don’t even know where I would put it. Is an air one bigger than the bandit set up?
