Hello-
A conservatory roof might be too big a job for him, but I have a friend in Cleish who is/used to be a builder. He generally just works on his own now, as I suppose he is heading towards retirement. If he can't help he might know someone who can?
His name is John Webster, contact number 01577 850318. He also breeds poultry, including scots dumpy's, scots grey's and gold pencilled hamburgh bantamn's!
