For the past 30 years I have done the following:
Dilute plain laundry bleach with water, one part bleach and three parts water. Apply with a pump garden sprayer. Apply when the moss is reasonably dry and thirsty like several days after the last rain. Wet it all; any you miss will not be killed.
In a few days the moss will turn brown and can be swept/brushed away. I just leave the dead moss alone and eventually it will go away. Anyone concerned about the bleach on the roof understand that sunlight will neutralize the chlorine shortly.
