So, need a new flat roof covering for a loft room. Was given two quotes, one for 3 ply torched felt system and the other for GRP fiberglass covering. The 2nd is a fair bit dearer but supposedly longer lasting. My question is, I've read that GRP can be quite noisey when it rains, would this be a deal breaker? Having slept up in the room, when it rains it already is fairly noisy already (to me anyway) and that is felt.
There is insulation in the roof BTW.
