Why choose single-ply roofing in Greenock?
For a commercial roof in Greenock 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.
Around Greenock, flat roofs are common on shops with flat-roofed rear stores below flats and on lock-up garage blocks on estates. 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.

How long does a single-ply roof last, and what guarantee comes with it?
A well-installed single-ply roof typically lasts 25 to 35 years or more. Its life depends mostly on the quality of the welds, the fixing pattern, protection from foot traffic and keeping outlets clear.
Signs of trouble on an older single-ply roof include seams lifting at the edges, shrinkage pulling at upstands and corners, punctures near plant, and loose fixings under the membrane on windy sites.
Manufacturer guarantees are available on many specified single-ply systems, and they often depend on a registered build-up, an inspection and sometimes an approved installer. Where the system allows, we complete that registration on your behalf. On every re-roof you also receive our written workmanship guarantee, with the length set out in the quote, and you can ask about insurance-backed options. See the guarantees guide and maintenance guide for more.

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.
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.
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.
