hi guys
I had a cony roof to do on Friday and i thought it would be a straight clean untill i got up there and took a look,
it was dotted with white lichen spots all over, had real trouble washing it off with the brush, each time i soaked it and then went back to it, it had dryed again as it was 27c here
and the heat was doing me in, in the end i used my mop on an unger pole to scub at it and it started to come off. How do you guys takle this?
Cheers fellas
