This goes for the corrugated sheets as well. Normal terracotta roofs don’t have this much moss/lichens.

    We have a terracotta roof that has similar amounts of moss, it’s about 45 years old. Most Eternit roofs are even older, so it’s no wonder there’s moss on it. Plus, many terracotta roofs are glazed and have a much smoother surface.

      Ah, that might very well be it. You’re right, ethernit does seem to have a rough surface, which would make it a much easier surface for moss and lichens to grow on.
