Hello, I've recently bought a 200yr. old cottage abroad quite cheaply with the view to renovate the place myself as and when I can. One of the features of the house that needs some attention is the roof - though only cosmetically it seems i.e. it's structurally sound but rather grey with large areas of discolouration. I was wondering if it's worth my while to clean up the roof tiles that are discoloured and paint the whole lot. Firstly, as the house is in a mountain area it's a fairly steep roof and I was wondering what sort of equipment I'd need, other than an extending ladder, to get the job done (a head for heights? yes got that already .) Secondly, what sort of paint could be used to paint the tiles - is there some that's specially made for this purpose? Any help gladly appreciated.
