Common flat roof problems on Maltby properties
Maltby is largely a residential town of semis and terraces, much of it built in the colliery era, with a steady stream of extensions, garages and outbuildings that rely on flat roofs.
Across these properties, the flat roof issues we're called out to in Maltby 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 Maltby 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 Maltby is welded, probe-tested and detailed to manufacturer standard, which is exactly what lets us back it with a 20-year workmanship warranty.

Maltby flat roofing — common questions
Do you cover Maltby? +
Yes — Maltby is within our South Yorkshire coverage area. Surveys are always free and we aim to respond quickly.

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 Maltby 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.
