What is single-ply PVC roofing? +
Single-ply PVC is a flexible, durable membrane laid in large sheets with hot-air welded seams, creating a fully watertight, seamless flat roof with a typical design life of 30–40+ years.
Why do you specialise in single-ply PVC? +
Because it's the best flat-roof system available — durable, weld-sealed into one continuous skin, and beautifully clean to look at. We'd rather be exceptional at one premium system than average at several, and it's what lets us back every roof with a 20-year workmanship warranty.
Do you charge for a survey or quote? +
No — surveys and written quotations are always free and no-obligation across our coverage area.
Which areas do you cover? +
We're based in Rotherham and cover all of South Yorkshire within roughly 20 miles — including Sheffield, Doncaster, Barnsley and the surrounding towns.
What guarantee do you offer? +
Every JLH installation comes with a 20-year workmanship warranty, on top of the manufacturer-backed system guarantee for the membrane itself — so both the materials and the quality of the fit are covered for the long term. We'll confirm the exact figures for your chosen system as part of your free survey.
How much does a new flat roof cost? +
It depends on size, access and specification, but as a rough guide single-ply typically falls around £90–£150 per m², with insulation and rooflights on top. The only accurate figure is a fixed quote after a free survey — see our flat roof cost guide for the full breakdown, or get an instant guide price with our cost estimator.
How long will 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?
Do you fit felt or GRP fibreglass? +
No — we specialise solely in single-ply PVC because it outlasts and outperforms both. Here's an honest comparison: single-ply vs felt vs GRP.
Do you cover commercial roofs as well as homes? +
Yes — from domestic extensions to large industrial roofs. See our commercial roofing service and recent projects.
