Single-ply membrane roofing in Tewkesbury

If you manage or own a commercial building in Tewkesbury, single-ply is often the most practical way to replace a large flat roof. We phase the work so the building stays weathertight, protect occupied areas, and add insulation and tapered falls where the roof needs them. Guide prices are online.

Why choose single-ply roofing in Tewkesbury?

Single-ply often suits blocks and mixed-use buildings in Tewkesbury because no flame is used on the roof, which can make work around residents and businesses easier to plan. Hot-air welding still needs care, but the fire risk is lower than with torch-on.

Around Tewkesbury, flat roofs are common on lock-up garage blocks on estates and on 1960s and 1970s link-detached houses with flat-roofed garages and porches. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

For Tewkesbury we use South West rates: £13,650–£22,450 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.

Should a single-ply roof be mechanically fixed or adhered, and how are the seams welded?

Most commercial single-ply roofs are mechanically fixed, while adhered systems suit decks that cannot take fixings or roofs where a smooth finish is wanted. The choice depends on the deck, the wind exposure of the site and the manufacturer's specification.

MethodHow it worksTypical use
Mechanically fixedFasteners and plates hold the membrane through the insulation into the deck, hidden under the lap of the next sheetMetal, timber and concrete decks on commercial roofs
AdheredMembrane bonded to the insulation or deck with adhesiveDomestic roofs, roofs where fixings are unsuitable
BallastedLoose-laid and held down by paving, gravel or a green roofInverted roofs, terraces, green roofs

Fixing patterns are worked out for the site, with more fasteners at corners and perimeters, where wind uplift is strongest.

Seams are welded by hot-air machines and hand tools that melt the overlapping edges so they fuse. Each seam is then probed along its length to find any gaps, and test welds are made at the start of the day to set the machine for the weather. On commercial jobs we also check that walkways protect the membrane around plant.

What's included?

  • Edge protection on every job and walkway protection around plant
  • PVC, TPO or FPO membrane, mechanically fixed, adhered or ballasted
  • Vapour control layer and warm-roof or tapered insulation as specified
  • Strip-out or preparation of the existing roof, with waste removed

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 Tewkesbury?

£13,650–£22,450 for a 100 m² commercial roof in single-ply with insulation, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Does single-ply work with solar panels or a green roof?

Usually, yes. Many systems can be specified for sedum or ballasted green roofs, and solar mounts can be welded or ballasted, though the structure and wind loads must be checked first.

Is single-ply roofing noisy in the rain?

No more than other flat roofs. Noise depends far more on the deck and insulation than on the membrane, and an insulated warm roof dampens rain noise well.
