Slates that have turned green

Sparky100 · 2012-02-13 12:01:01

I have noticed recently near a dormer window the slates look very green, maybe even some moss but doesn't look that thick more the colouring..... I know I can easily get to them through dormer window or with ladder but what product would I be best to use on them for cleaning?

Buy a cheap sprayer in Lidle or aldi, buy a drum of MossGo, not the pre diluted one, get the one you have to dilute yourself. Get the ladder and spray the roof with a strong mix. It will disappear in a day or so.
Have to do my own again, did it about 2 years ago. You will find that its only on north Facing roof that it occurs.
