Why choose single-ply roofing in Gosport?
Single-ply also works on an extension or garage in Gosport if you want a light, clean finish in a pale colour. On small roofs it is usually adhered, and while it can cost more than EPDM, it gives the same welded seams and details found on commercial roofs.
Gosport's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on bungalows with flat-roofed side extensions and dormers too. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a single-ply roof cost in Gosport?

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.
What's included?
- Strip-out or preparation of the existing roof, with waste removed
- Welded details at upstands, outlets, rooflight kerbs and edge trims
- Vapour control layer and warm-roof or tapered insulation as specified
- PVC, TPO or FPO membrane, mechanically fixed, adhered or ballasted
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.

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.
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.
