How can I get rid of moss on the roof?

John Conlin / 05 September 2017

Chartered surveyor John Conlin tackles the problem of mossy tiles.



Question

One slope of our clay tiled roof always has moss growing on it which is then dislodged, rolls down and blocks the gutter. 

I have tried spraying weedkiller without success – is there a solution?

How to find a reliable builder.

Answer

Copper salts will deter the growth of moss. Have strips of copper secured by tucking the ends beneath the overlap between rows of tiles near the top of the roof leaving as much of the strip as possible exposed. 

Rain will pick up and carry copper salts in solution down the roof.
