Cleaning a tiled roof

[Squonk]

I have a tiled roof on detached house that is ~15 years old. The roof has a fair bit of moss on it and could do with a good clean. Who does this? A roofer? How much would I expect to pay, and can anyone recommend someone in Cork? Thanks as always.

Don't know about anyone in the Cork area as I'm not from the deep south bible belt
However I'm sure if you look in your local yellow pages/red book etc etc find a guy that does power washing and get a price from him, it'll prob warrant hireing a cherry picker(€150-200/day) then whatever the power washing guy wants to charge you for his day, depending on the size of roof €500 tops.

Thanks Movax....I found a place in the UK that does exactly what I want : [broken link removed] They seem to do more than just power washing; they use chemicals to kill the roots of the moss and algae. I can't find anything similar in Ireland, least of all down here in the bible belt
