Jeyes fluid moss on roof. I use diluted jeyes fluid in a watering can for killing off the moss on our block paving. Allow 30 minutes then rinse off with water and scrub with yard brush. It is used by by vegetable gardeners to sterilise the soil and does not harm. Alternatively a low pressure wash with jeyes fluid or similar may do the trick applied by a long arm pipe brush.
After about five or six years when the original polymer coating on concrete tiles has dissolved away or after cleaning off old moss and lichen it would be worth treating the surface of the tiles with a biocide a cocktail of fungicide bactericide and algaecide or a very strong horticultural disinfectant like jeyes fluid.

Leave it until the moss withers then just brush it off. Since ec regulations in 2003 the product is no longer effective at killing moss nor will it be effective at preventing moss re growth.
