The working process
From first inspection to finished roof.
The exact method depends on the existing roof, but the work follows a clear sequence focused on preparation and waterproof detailing.
- 01
Inspect and specify
The roof construction, deck, falls, drainage and details are checked before the membrane build-up is selected.
- 02
Prepare the roof
The deck and vulnerable areas are made sound, clean and suitable for the specified single-ply system.
- 03
Install the membrane
The PVC membrane is laid and joined with careful attention to seams, perimeters and roof penetrations.
- 04
Detail and inspect
Edges, outlets, upstands and junctions are completed, then the finished roof is inspected throughout.

Details matter
A flat roof is only as reliable as its vulnerable points.
