Hi Guys,
Any ideas on the best Biocide for a standard tiled roof ( Red Norfolk tiles ).
Its my house so giving it a go, when i get chance. Will clear most of moss off with a scraper (not loads of it), then apply a biocide.
Ive been looking at Smartseal "Green clear" and ACP "Algo clear" both biocides, just different concentrations of biocide im sure. Just wondered who had used either product and found them okay, or any other used (only biocides please).
Thanks in advance
