No Pete, I've never done it before but now looking at the process wish i was giving it a go. If i had more time to be honest id like to but you know how these things are. Sometimes although you could probably do a job its better to just gt someone in to do it for you as its quicker and allows you time to do other things.
I was concerned with the setting out around the windows and that still concerns me as there are a lot of factors to make it lk nice. Same as our tiling really only we can adjust ours laterally and the roof tiles only have a small amount of movement in either direction.
Having said all that i do have to get the gear up there for him as that was the deal on the price he gave me. 3000 large pan tiles and 2700 plain tiles! Not looking frward to that one!
