My house has an East-facing ground floor bit that is part flat roof,
part pan tiles and quite near a big tree. The moss on it getting quite
bad so I'm tempted to get out on the flat bit to "down-slope" pressure
wash the tiles (not the flat roof).
Is there any other way and, once it's clear, is there any way to slow
the moss re-growth?

Copper wire?
