The different layers of GRP roofing I understand that fibreglass roofing is made up from different layers of materials but can you tell me what are those layers and how the roof gets built up.
We made a video on this to show the different layers that go into making a fibreglass roof, check it out below; Hope this helps. If you have any more questions, please give us a call.
Ask the Allbase team and we'll add the answer here for everyone.
