Can anybody give me a very rough idea how much it would cost to refelt a flat roof approx 8ftx18ft. Some of the timbers need replacing but I need some idea of the basic cost so I can budget this in with some other work that I doing. It was last done about 22 years ago. Would this be about the life span of a flat roof? The felt actually looks ok and I can't detect any leaks but I have the ceiling down for other work and the timber in a couple of area looks bad but could well be from before the last refelting.
Thanks
Kevin
