Be careful not to strip the top gritty layer off the tile .. You'll make it an ice rink for the next unlucky person to go up there on a damp day.. In all honesty just a scrape with a hoe does the trick and wash it off with hose pipe.. Wouldn't worry about eating your dinner off it.. Results last a good few months unless surrounded by trees and such.. Best of luck

If you just spray with a hose the moss will be back by newyear, I have de mossed the roof and I have just applied the Benz biocide wash I understand the bio wash will take time to revive the roof but what I'm asking is customer wants to know if they spend xxxx amount of money will it be worth it and how long approx will roof be clean ??

I ve done quite a few of these now either by hand and pressure washing as i m a roofer. Not used a biocide as of yet. But the ones i ve done usually last a good few years tbh. Dependant on surrounding areas. Unlike the patios they tend to stay clearer for longer imo.
