Why did early fibreglass roofs get such a bad reputation?
There were many reasons, not least of all the resins used in the early days of GRP roofing were often obtained from boatyards. These resins were perfectly good for making stiff yacht hulls, but they were designed to be stiff – not flexible, and would not elongate as the boarding expanded, which resulted in splitting. All Matrix Roofing roofing resins are plasticised – and accommodate the expansion of the deck without lesions; so much so that up to 50m2 you do not need an expansion joint. Above 50m2 ask our technical dept. GRP roofs have also improved as roofers have become more experienced and knowledgeable about how to laminate. Matrix Roofing offer technical support and training courses.
