SNAP, I don't mind the moss but the lichen is a nightmare to remove. Started last winter but haven't had time nor the motivation to finish the job. A 50° roof pitch doesn't make it easy either 😠


Gordon, I too have some steep roofs, beginning to wish I had made the garage a flat roof instead of tiled. At least my tiles are flat, a mock slate appearance, but they seem to provide ideal conditions for moss to inhabit. I would not fancy removing the amount of moss that is on my roofs from tiles like yours...! A property maintenance chap I know suggested spraying the roof with Deosan Red Lable Hydrochlorite, but just looking at the data sheet scared me off, so back to the scraper and wire brush..
