roof moss

I'm assuming they're roof type tiles (even though somehow below the gutter level)??

A diluteable moss killer such as this will work. You can spray it on - or brush it on (less risk of spray drift) if easy access to the tiles.

sorry,i thought after i read it that it looked bit confusing,you could say there a type of roof tyle,but they are on the top half front/back wall

Right - I did kind of assume that. But a standard diluteable moss killer should do the job - even though it's more typical for lawns / Yorks stone paths.

B&Q may still do a liquid variety - and likely cheaper than the one I flagged up. But spraying it on will be a problem, where the tiles are situated - as you'll get covered in drift? So it's safer with a ladder / brush? But keep the brush handle pointing upwards - or your armpits will be deodorised in the stuff!!

Many years ago a friend was told by a large company to use diluted bleach. It worked for him.
