        And what do you think the moss likes about the edge? Rough substrate with plenty of surface area and maybe some water retention?

        Somebody here said there was more than one layer; I see hear that the slate is being attached to boards. What do you attach the second layer to?

      I’m gonna guess that they are slate or ceramic not wood.

      And there is more than one layer.

        I’m proud to live in a brick condo, but I’m ashamed of our flat tar paper roof.

        I’ve always thought overlapping was such a clever and effective thing that everyone would be doing it, but I guess you can really only overlap materials that are relatively easy to poke holes in, so overlappable material probably doesn’t last as long as multiple (2?) layers of slate.
