Single-ply membrane roofing in Bargoed

Single-ply roofing in Bargoed means one welded layer of PVC, TPO or FPO membrane over insulation, fixed to suit the deck and the exposure of the site. It is light, quick to lay on larger roofs and flame-free, with seams fused by hot air rather than a torch.

Why choose single-ply roofing in Bargoed?

Single-ply also works on an extension or garage in Bargoed 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 a town like Bargoed, flat roofs are commonly found on low-rise post-war blocks of flats or terraced streets with flat-roofed rear kitchens and bathrooms. 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.

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?

  • Vapour control layer and warm-roof or tapered insulation as specified

  • Hot-air welded seams, each probed along its full length

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.
