EPDM rubber is currently considered one of the most durable options for residential flat roofs, with a typical lifespan of 25 to 50 years and strong resistance to the temperature variation common in London. Fibreglass (GRP) is also highly durable and particularly suited to complex roof shapes. We assess your roof, budget, and property type during the free survey and recommend the most appropriate system.
