Why choose single-ply roofing in Brynmawr?
On exposed sites in Brynmawr and elsewhere, mechanically fixed single-ply is specified with a fixing pattern based on wind uplift, with extra fasteners at corners and edges. That makes it a strong option for commercial roofs where wind loads are a concern.
Brynmawr's flat roofs are mostly on lock-up garage blocks on estates, with plenty on terraced streets with flat-roofed rear kitchens and bathrooms too. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.
How much does a single-ply roof cost in Brynmawr?
At Wales guide rates, a 100 m² commercial roof in single-ply with insulation comes to £12,150–£20,050 including VAT. 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 | £12,150–£20,050 |
| Single garage (18 m²), single-ply | £1,900–£3,050 |
| Single garage (18 m²), EPDM rubber | £1,450–£2,600 |
| Extension (20 m²), EPDM, new deck + insulation | £2,600–£4,500 |
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.

Building regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

How much does a single-ply roof cost in Brynmawr?
£12,150–£20,050 for a 100 m² commercial roof in single-ply with insulation, at Wales 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.
