We moved into our current house nearly 3 years ago. It's got a medium sized conservatory at the back, which we use as a bit of a 'playroom' and store all the kids toys etc in there. It's part brick built, but with a PVC roof. The roof condition is now pretty poor and it has some small leaks, so the conservatory is getting cold and damp. How much do you reckon it would be to put a 'proper' or better roof on? Or would it be better just to replace with another PVC one so you think?
