I had the extension built 2 years ago and opted for fibre glass instead of felt roofing because it has a longer life span.Trouble is i am getting the most unbelievably loud banging noises coming from it.The manufacturers ,Topseal, have been of little help and I cant find much on the net.
Apparently its to do with different expansion and contraction between the wooden structure and the fibre glass as it heats and cools down.Now i dont know whether my roof is at risk but what i do know is that if i ever choose to sell this house i may have problem doing so because of the noise.I just wonder if anyone has any experience of this kind of roofing and any suggestions
