Single-ply membrane roofing in Oban

If you manage or own a commercial building in Oban, 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 Oban?

If a flat roof in Oban has poor falls and ponding, a single-ply re-roof with tapered insulation can correct both problems at once. The tapered boards build the fall into the insulation, and the membrane is laid over the top, with outlets set at the new low points.

In and around Oban, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on low-rise post-war blocks of flats. 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?

  • Edge protection on every job and walkway protection around plant
  • Welded details at upstands, outlets, rooflight kerbs and edge trims
  • Strip-out or preparation of the existing roof, with waste removed
  • Vapour control layer and warm-roof or tapered insulation as specified

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.

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.

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.
