Renolit Single Ply Roofing: Why We're Approved Installers
We install single ply systems from several leading manufacturers, but Renolit is one we’re especially proud of: we’re award-winning Renolit installers. Here’s what that means, why the membrane outperforms the rubber and fibreglass roofs it’s often compared with, and where we fit it across Doncaster and South Yorkshire.
What is Renolit single ply?
Renolit is a long-established manufacturer of PVC single ply roofing membranes, best known under the Alkorplan name. Like all quality single ply, it’s laid over insulation and the seams are hot-air welded into one continuous, joint-free skin, so there are no glued laps or torch flames involved.
The result is a durable, flexible waterproofing layer that suits everything from a small domestic extension in Bessacarr to a large commercial roof near the M18.
Why it beats EPDM and GRP
Homeowners often weigh a single ply roof against rubber (EPDM) or fibreglass (GRP). On the technical points that decide how long a roof lasts, Renolit single ply comes out ahead:
- Versus EPDM rubber: EPDM is joined at its seams and details with adhesives and tapes, and that bond is what ages and fails first. Renolit’s welded seams fuse the membrane into a single piece, with no glue to perish.
- Versus GRP fibreglass: GRP is rigid and prone to crazing and cracking as the deck moves, and it needs dry, warm weather to cure. Renolit stays flexible, moves with the building and welds in cooler, more variable conditions.
If you want the full comparison, see our EPDM vs GRP vs single ply guide.
Why we rate it
- Proven durability. Renolit membranes have a strong track record and carry long manufacturer guarantees.
- Clean detailing. The membrane stays flexible, so it dresses neatly around upstands, outlets and rooflights.
- Range of finishes. Various colours and profiles mean the roof can suit the building, including options that mimic a standing-seam metal look.
- Backed by a major manufacturer, with a guarantee that genuinely stands behind approved installation.
What “approved installer” actually means for you
Single ply is only as good as its installation. A manufacturer-backed guarantee depends on the membrane being fitted by a trained, approved installer to the manufacturer’s specification. Being an award-winning Renolit installer means your roof is fitted to that standard and the guarantee genuinely stands behind it. You can read more about our approach on our about page.

Frequently asked questions
What is Renolit Alkorplan?
Alkorplan is Renolit's range of PVC single ply roofing membranes. Like all quality single ply, it is laid over insulation and the seams are hot-air welded into one continuous, joint-free skin, giving a durable, flexible waterproof layer suited to homes and commercial roofs alike.
Is Renolit single ply better than a rubber or fibreglass roof?
For most roofs, yes. A welded Renolit membrane has no adhesive joints to perish like EPDM rubber, and no rigid surface to crack like GRP fibreglass. It stays flexible, seals without glue and carries a long manufacturer guarantee.
What does it mean that you are award-winning Renolit installers?
A manufacturer-backed guarantee only stands up if the membrane is fitted by a trained, approved installer to the manufacturer's specification. Being award-winning Renolit installers means your roof is fitted to that standard and the guarantee genuinely stands behind the work.
Do you fit Renolit single ply roofs in Doncaster?
Yes. We fit Renolit and other single ply systems on domestic and commercial roofs across Doncaster, Rotherham, Barnsley, Mexborough and the surrounding South Yorkshire towns. Renolit is one of several systems we are approved for, so we specify it where it suits the roof.
