What is EPDM roofing?

The main alternative to a fibreglass roof, is EPDM (ethylene propylene diene monomer), which is a type of rubber roofing. It’s sold in rolls that can be easily installed to cover a flat roof. EPDM roofing is durable and flexible making it a great option for covering uneven roof surfaces.

• Location: Depending on where you live in the UK, labour costs can vary.

• Access: If your roof is difficult to access, this will push up the labour costs.
