Single-ply membrane roofing in Castleford

For landlords and businesses across West Yorkshire, including Castleford, we strip and re-roof in single-ply membrane, welding and probing every seam. Upstands, outlets and rooflight kerbs are formed in the same material, and the fixing pattern is worked out for the roof's exposure to wind.

Why choose single-ply roofing in Castleford?

On exposed sites in Castleford 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.

Castleford's flat roofs are mostly on lock-up garage blocks on estates, with plenty on bungalows with flat-roofed side extensions and dormers too. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

How much does a single-ply roof cost in Castleford?

At Yorkshire and the Humber guide rates, a 100 m² commercial roof in single-ply with insulation comes to £12,550–£20,700 including VAT. 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?

  • Hot-air welded seams, each probed along its full length
  • PVC, TPO or FPO membrane, mechanically fixed, adhered or ballasted
  • Strip-out or preparation of the existing roof, with waste removed
  • Welded details at upstands, outlets, rooflight kerbs and edge trims

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.
