EPDM Flat Roofing in Norfolk
J Mann Roofing has over 20 years' experience installing, repairing and replacing EPDM flat roof systems across Norwich and Norfolk. Whether it's a new extension roof or a failing felt covering that needs attention, we'll find the right solution.
EPDM Rubber Roofs
We install Elevate RubberCover™ EPDM (formerly Firestone RubberCover) — a single-ply rubber membrane that bonds directly to the roof deck. Once laid, it forms a seamless, watertight layer with no seams to split or lift, protecting your property from leaks and the elements.
The system carries a 20-year warranty, and the membrane itself typically lasts well over 50 years — making it one of the most durable options available for flat roofs.
EPDM also resists UV degradation, handles thermal movement without cracking, and sits flush against the roof edge, so there's nothing to peel back or deteriorate at the perimeter.
Free Advice
Not sure whether you need a repair or a full replacement? We offer free, no-obligation surveys and advice — just get in touch to discuss your situation. We'll assess the condition of your roof and walk you through the options, including our Elevate RubberCover™ EPDM system with its 20-year warranty.
If you'd rather send details by email, a few photographs and an idea of the roof dimensions are enough for us to give you an initial indication.
EPDM Flat Roof Installation
For new extensions, garden rooms, garages and commercial buildings, we install Elevate RubberCover™ membranes from scratch. The system is fully bonded to the roof deck, creating a seamless, watertight finish with no joints to split or lift. Every installation includes proper falls for drainage, reinforced edge details and a 20-year material warranty — so you get a roof that's built to last from day one.
EPDM Flat Roof Replacement
When an existing felt or GRP roof has reached the end of its life — showing signs of bubbling, tearing, ponding or persistent leaks — we strip it back to the deck, inspect and repair the substrate where needed, and bond a new Elevate RubberCover™ membrane in its place. Most domestic re-roofs are completed within two to three days, keeping disruption to a minimum.
Flat Roof Repairs
Not every flat roof problem requires a full replacement. We carry out targeted repairs on EPDM, felt and GRP systems — sealing punctures, patching tears, fixing flashing details and resolving ponding issues around outlets and upstands. Our aim is to extend the life of your existing roof wherever possible, carrying out only the work that is genuinely needed and providing a clear quote before we start.
