Currently part way through moss removal on my many (too many) concrete tiled roofs, halted for a bit of medical intervention. but hoping to get back up there soonest.... I wonder if moss growth has increased now that acid rain has been reduced perhaps as the result of demolishing all the coal fired power stations...?
K stupidly long working day... been there done that and for years and years, to end up creating all those effing roofs.... Double DUH..!
