Why choose single-ply roofing in Oswestry?
For a commercial roof in Oswestry 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 and around Oswestry, flat roofs are typically found on low-rise post-war blocks of flats, and on 1960s and 1970s link-detached houses with flat-roofed garages and porches. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.
How much does a single-ply roof cost in Oswestry?
At West Midlands guide rates, a 100 m² commercial roof in single-ply with insulation comes to £13,250–£21,800 including VAT. The fixed price comes after a free survey for new and replacement roofs.

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 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 Oswestry?
£13,250–£21,800 for a 100 m² commercial roof in single-ply with insulation, at West Midlands 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 be used on a house?
Yes. It can be used on garages, extensions and dormers, usually adhered rather than mechanically fixed. On small domestic roofs, though, EPDM or GRP is often more economical.
