Single-ply flat roofing in Mexborough
Mexborough is twenty minutes from our Rotherham base along the Dearne, and JLH covers the town and its neighbours — Denaby Main, Old Denaby, Conisbrough and Harlington — for single-ply installation, repairs, maintenance and leak detection.
Single-ply PVC done properly: seamless, welded, watertight and built for the long term.
Flat roofs in Mexborough: the local picture
Mexborough is a traditional Dearne market town of long brick terraces, a busy High Street and interwar semis around Adwick Road and the Pastures, with the colliery village of Denaby Main to the east and Conisbrough — castle and all — beyond it. Its flat roofs are mostly the working kind: outriggers behind the terraces, shop roofs above the High Street, garages and extensions on the semis, and small units around the station and the river. Most were felted, many more than once.
The work that comes out of that mix is consistent. In Mexborough we are most often asked for:
- Terrace outrigger and rear-extension re-roofs across Mexborough and Denaby Main
- Shop and flat roofs above the High Street and around the station
- Garage and porch roofs on interwar semis around Adwick Road and the Pastures
- Extension warm roofs in Conisbrough and Harlington

The flat roof problems we fix in Mexborough
- Outrigger roofs on their third felt with the deck softening underneath.
- Shop roofs with blocked outlets and water finding its way into the stockroom below.
- Bay and porch roofs mastic-sealed at the wall and leaking every winter.
- Garage roofs sagging and ponding behind the house.
- Condensation in cold-roof extensions mistaken for leaks.
If the leak is hard to place we test for it electronically rather than guess — see leak detection. If the roof is simply finished, we tell you straight and price a replacement that lasts.
What we typically install in Mexborough
For a Mexborough terrace we strip the felt, check and repair the deck, insulate above it and weld new single-ply with a proper upstand at the party wall and the house — the abutment is where these roofs fail. Shop roofs are planned around trading hours and usually overlaid rather than stripped; garages and porches get the same care scaled down.
| System | Typical lifespan | Joints | Where we use it |
|---|---|---|---|
| Felt (bitumen) | 10–20 years | Lapped & bonded | We don't — it is what we replace |
| GRP (fibreglass) | 20–25 years | Hand-laid resin | We don't — it cracks with movement |
| Single-ply PVC, adhered | 30–40+ years | Hot-air welded | Visible roofs where a flush finish matters |
| Single-ply PVC, mechanically fixed | 30–40+ years | Hot-air welded | Larger and more exposed roofs |
Wondering how that stacks up against the felt you have now? Read single-ply vs felt vs GRP.
A local specialist, not a general roofer
Most flat roofs in the Dearne Valley were fitted by whoever was doing the pitched roof at the time. Single-ply is a different trade: it is welded, not laid, and the detailing at every upstand and outlet is where the skill lives.
That is all JLH does. Eighteen years of it, with manufacturer training and approval across Sika, Protan, Alwitra, Fatra, IKO, Icopal, Decothane and Triflex — so the membrane on your roof is specified by the people who make it and fitted by people who fit nothing else. Every installation carries our 20-year workmanship warranty.

Mexborough flat roofing — your questions
Do you cover Denaby and Conisbrough? +
Yes — Denaby Main, Old Denaby, Conisbrough and Harlington are all part of our Mexborough patch, along with the rest of the Dearne.
How much does a flat roof cost in Mexborough? +
Around £90–£150 per m² supplied and fitted for single-ply, with insulation, rooflights and deck repairs on top. The estimator gives a range in a minute; a free survey gives a fixed quote.
Can you re-roof a shop without closing it? +
Usually, yes. We plan the work around trading hours, keep the roof watertight at the end of every day and, where the deck is sound, overlay rather than strip so there is no open roof over the stock.
Does a terrace outrigger roof need scaffolding? +
Often a tower or a short scaffold on the rear, sometimes just ladders and edge protection — it depends on height and access. We include whatever is needed in the fixed quote.
Should I repair or replace my flat roof? +
If the fault is local and the covering is otherwise sound, repair. If it is widely worn, blistered or on multiple layers, replacement is better value. We tell you which honestly at the free survey — see our guide to the signs your flat roof needs replacing.
Can you add a rooflight during a re-roof? +
Yes — a re-roof is the ideal moment. We form the kerb and weld the membrane over it as part of the new roof.
What guarantee do I get? +
A 20-year JLH workmanship warranty plus the manufacturer’s system guarantee for the membrane.
How far are you from Mexborough? +
About twenty minutes from Rotherham along the Dearne, through Swinton. Surveys and call-outs are straightforward.
