Flat roofing covers a wide range of properties and structures — house extensions, bay windows, garages, outbuildings, and commercial units. In Ely and across the Fens, flat roofs face particular challenges: the area's relatively high rainfall combined with very flat terrain means standing water and drainage failure are common causes of early roof breakdown. We install and repair flat roofs using GRP fibreglass, EPDM rubber membrane, and torch-on felt systems, choosing the right material for each application.
GRP fibreglass is our most-recommended system for new flat roofs on extensions. It's seamless, extremely durable, and when installed correctly typically lasts 25 years or more with very little maintenance. EPDM rubber is well-suited to larger or more complex roof areas where movement in the deck is a concern. Traditional torch-on felt remains a practical option for garages and outbuildings where budget is the primary consideration. For all systems, correct falls and drainage are as important as the membrane itself — a flat roof that doesn't shed water promptly will fail early regardless of the material.
Old felt roofs that are bubbling, cracking, or pooling water shouldn't be patched repeatedly — each patch is another potential leak waiting to happen. We'll assess whether a repair is viable or whether a full overlay or strip and replacement is the right call, and we'll be straight with you about it.
We strip the old covering, inspect and repair the decking where needed, install the new system, and make good any upstands and abutments. Most flat roof replacements on an average extension take one to two days. Flat roofs in Ely typically cost £70–£120 per square metre for GRP fibreglass installation, depending on access and detailing. Call us for a free flat roof survey and written quote.
