How Have EPDM Roofing and GRP Roofing Changed the Game?
EPDM stands for Ethylene Propylene Diene Monomer, an extremely durable synthetic rubber. EPDM is heat and weather-resistant thanks to its two primary ingredients, ethylene and propylene, making it an ideal solution as a roofing material. EPDM roofs can last up to 50 years when professionally installed and well maintained. Though GRP roofing and EPDM roofing cost more than other roofing alternatives, there is no denying that their impact on the scene has changed the roofing industry.
GRP flat roofing’s superiority comes down to it being a durable, lightweight, flexible, fully reinforced, and waterproof material capable of being molded to any shape. EPDM roofing can resist both subzero temperatures and extreme heat. Its resilience to the elements is impressive. EPDM also has a lower carbon footprint than other traditional alternatives like felt because of its reduced need for regular replacement coupled with its insulating properties that help bring down the building’s heating costs. Both GRP flat roofing and EPDM roofing boasts one of the roofing industry’s longest average service life.
How Much Does a Fibglass Roof Cost?
The cost of GRP fibreglass roofing varies depending on the scale of the job at hand and location. These primary costs vary depending on whether a new roof is being constructed or an existing roof is being repaired, with the latter sometimes being cheaper depending on the extent of repairs required. You might think that GRP fibreglass roofing costs a great deal more than other roofing systems given its strength and superior durability, but this is not the case. It is more expensive than felt or EPDM rubber roofing systems, but when you factor in its longevity, simple maintenance, impressive resistance to the elements and beautiful aesthetic, fibreglass roofs are worth the slightly higher costs.

Prices and Durability
Before thinking of price, identify whether you need a new roof or a repair. If it’s a repair, how bad is the damage and is the cost of repairing extensive damage worth more than that of a new roof? Are there any structural repairs that need to be carried out on the roof? Any alterations required for the guttering or downpipes? You will also need to consider the surface area of the roof when budgeting for your GRP roof.
You can expect costs to be between £70-£90 per square meter for a GRP roof, although this price will differ depending on location. A DIY installation will be substantially cheaper, of course.
