Why choose single-ply roofing in Ely?
Single-ply also works on an extension or garage in Ely if you want a light, clean finish in a pale colour. On small roofs it is usually adhered, and while it can cost more than EPDM, it gives the same welded seams and details found on commercial roofs.
In and around Ely, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, and on bungalows with flat-roofed side extensions and dormers. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.
How much does a single-ply roof cost in Ely?
For Ely we use East of England rates: £13,900–£22,850 is the guide for a 100 m² commercial roof in single-ply with insulation, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Commercial roof (100 m²), single-ply + insulation | £13,900–£22,850 |
| Single garage (18 m²), single-ply | £2,150–£3,500 |
| Single garage (18 m²), EPDM rubber | £1,700–£2,950 |
| Extension (20 m²), EPDM, new deck + insulation | £2,950–£5,150 |
Is single-ply the right system for my roof?
Single-ply is usually the right system for medium and large flat roofs, such as shops, offices, units, surgeries, clubs and blocks, where speed of installation, light weight and long life matter. On a small domestic roof it can work well, though it is not always the most economical choice.
In its favour: lightweight; quick to lay over large areas; flame-free, as the seams are welded with hot air; long typical life; welded details at rooflights and plant; lighter-coloured membranes reflect more sunlight.
Against it: only one waterproof layer, so welding quality is critical; can be punctured by foot traffic or dropped tools without walkway protection; PVC needs separating from bitumen; repairs need compatible material and welding equipment.
For a small garage or extension, EPDM is often simpler. Where people walk regularly, GRP or a liquid system may be tougher. A multi-layer torch-on felt roof gives built-in redundancy, and on older buildings mastic asphalt may be the original material. Our commercial flat roofing page covers larger jobs.
What's included?
- Welded details at upstands, outlets, rooflight kerbs and edge trims
- PVC, TPO or FPO membrane, mechanically fixed, adhered or ballasted
- Strip-out or preparation of the existing roof, with waste removed
- Edge protection on every job and walkway protection around plant
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a single-ply roof cost in Ely?
£13,900–£22,850 for a 100 m² commercial roof in single-ply with insulation, at East of England guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
What is the difference between PVC and TPO roofing?
Both are thermoplastic single-ply membranes welded with hot air. PVC contains plasticisers and usually needs separating from bitumen, while TPO and FPO are polyolefin-based; the right one depends on the roof and the system specified.
Can a single-ply roof be repaired?
Yes. A compatible patch is cleaned and hot-air welded over the damage. Older membranes may need extra cleaning before they weld properly, which the team checks on site.
