Common flat roof problems on Mexborough properties
Mexborough is a traditional Dearne town with rows of terraces, semis and a busy high street. Flat-roofed extensions, outriggers and shop roofs are common throughout the area.
Across these properties, the flat roof issues we're called out to in Mexborough are remarkably consistent:
- Failed felt and ponding water on older extension and garage roofs.
- Cracked or crazed GRP that has gone brittle with age and UV.
- Leaks around upstands, parapets and rooflights where the original detailing has let go.
- Blocked outlets and poor falls leaving water standing for days.
- Cold, condensation-prone roofs on older builds that pre-date warm-roof construction.
The fix for almost all of these is the same: a properly specified, fully-welded single-ply PVC system — and where the fault is hidden, electronic leak detection to find it precisely before we repair.
Single-ply vs felt & GRP
Traditional felt and GRP fibreglass have had their day. Here's how the three main flat-roof systems compare — and why we only fit single-ply for Mexborough roofs.
| System | Typical lifespan | Joints | Best for |
|---|---|---|---|
| Felt (bitumen) | 10–20 years | Lapped & bonded (weakest) | Low-budget, short-term |
| GRP (fibreglass) | 20–25 years | Hand-laid resin | Small roofs, dry-weather installs |
| Single-ply PVC | 30–40+ years | Hot-air welded (strongest) | Almost any flat roof |
Single-ply stays flexible and UV-stable for decades, the welded seams form one continuous skin with no laps to lift, and it carries strong manufacturer-backed guarantees. For the full breakdown, read our guide: Single-ply vs felt vs GRP.
Single-ply is only as good as the installer
The performance of a single-ply roof is all in the welds. A sound, fully watertight hot-air weld takes the right equipment, manufacturer training and years of hands-on experience to achieve consistently — get it wrong and a seam becomes tomorrow's leak.
JLH brings 18 years' experience and is manufacturer-trained and approved across eight leading systems — Sika, Protan, Alwitra, Fatra, IKO, Icopal, Decothane and Triflex. Every roof in Mexborough is welded, probe-tested and detailed to manufacturer standard, which is exactly what lets us back it with a 20-year workmanship warranty.

Mexborough flat roofing — common questions
Do you cover Mexborough? +
Yes — Mexborough is within our South Yorkshire coverage area. Surveys are always free and we aim to respond quickly.
How much does a flat roof cost in Mexborough? +
It depends on the size, access and specification of your roof. As an indicative guide single-ply typically falls around £90–£150 per m², but the only accurate figure is a fixed quote after a free survey. See our flat roof cost guide for the full picture.
How long does a single-ply roof last? +
A correctly installed single-ply PVC roof has a design life of 30–40+ years — comfortably longer than felt or GRP. More in our guide: how long does a flat roof last?
Is single-ply better than felt or GRP? +
For flat roofs, we believe so: hot-air welded seams (rather than glued laps or hand-laid resin), a longer lifespan, better flexibility and a cleaner finish — all backed by stronger manufacturer guarantees.
Can you repair my existing flat roof, or does it need replacing? +
Often a localised fault can be repaired — and electronic leak detection finds it precisely. Widespread wear or a failed deck usually points to replacement. A free survey will tell you honestly which you need.
What guarantee do I get? +
Every JLH installation comes with a 20-year workmanship warranty, on top of the manufacturer's system guarantee for the membrane.
Do you charge for a survey or quote? +
No — surveys and written quotations are always free and no-obligation across Mexborough and the wider area.
Do you do commercial flat roofs too? +
Yes — from small units to large industrial roofs. See our commercial roofing service and recent projects.
