Why choose single-ply roofing in Haddington?

For a commercial roof in Haddington with rooflights, plant and outlets, single-ply's welded details give a consistent finish. Pre-formed corners, membrane-coated trims and welded kerbs are all made in the same material as the main roof, which keeps the roof consistent and simplifies any future repairs.

In a town like Haddington, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or bungalows with flat-roofed side extensions and dormers. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

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?

  • Welded details at upstands, outlets, rooflight kerbs and edge trims
  • Hot-air welded seams, each probed along its full length
  • Edge protection on every job and walkway protection around plant
  • PVC, TPO or FPO membrane, mechanically fixed, adhered or ballasted

Building standards in Scotland

In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

£12,550–£20,700 for a 100 m² commercial roof in single-ply with insulation, at Scotland 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 single-ply roofing be laid over an existing roof?

Sometimes, if the existing roof and deck are dry and sound, often with a separation layer or new insulation on top. Wet insulation or a damaged deck means stripping first.
