Hi Marianne We are installers of various single ply flat roofing membranes. Like most products available GRP (fibreglass) is a good system when properly installed. Unfortunately there is very little regulation on who is buying and indeed installing GRP so do your homework on any contractors to ensure your getting a good job. We on average remove half a dozen GRP roofs a year that have only been fitted a very short amount of time due to poor workmanship so it's all about checking that the tradesmen are reputable. I hope this helps Regards Alistair
