MOSS ON CONCRETE interlocking tiled roof.
2 yrs ago cleaned all moss off my roof scraping and brushing, ruled out jet spray as it would take off the tiles sand faced surface and may be eat in to the tiles.
I notice in some small areas its growing back so anyone got a permanent solution?
Many thanks in anticipation

I've got a similar problem with moss growing on tarmac (see picture). I am thinking that this stuff might do the trick.

Does anyone have any experience of using it?
