Single Ply Membrane Roofing Scotland
Single ply membrane repairs, surveys, refurbishment and Sika membrane installations for commercial and industrial roofs.
Modern Roofing repairs many types of single-ply membrane roof, but for new commercial and industrial single-ply systems we believe Sika is the best partner to stand behind.
This page is for clients dealing with:
- Single-ply membrane leaks or failed details
- Bauder, Protan, Sika, IKO, Alwitra, Renolit, Fatra or EPDM membrane defects
- Old flat roofs needing repair, survey or refurbishment
- Choosing between repair, overlay, renewal or a new Sika system
Single Ply Membrane Roofing Scotland from Modern Roofing
Single-ply membranes are widely used on flat and low-pitch commercial roofs because they are lightweight, flexible and suitable for many new build and refurbishment projects. On industrial buildings, they are commonly used on warm roofs, overlay projects, roof extensions, plant areas, gutter details and large flat roof areas.
Modern Roofing carries out single-ply membrane inspections and repairs across Scotland, including Glasgow, Edinburgh, Lanarkshire and the wider Central Belt. We can assess leaks, failed laps, punctures, splits, detailing issues, ponding, outlet problems, rooflight junctions and old repair patches.
The key point is simple: we can repair and assess many membrane systems, but when we are designing or recommending a new single-ply waterproofing system, our view is that Sika is the best choice for the type of commercial and industrial roofing work we want to stand behind. We chose Sika because of the strength of the system range, technical support, warranty options, detailing standards and long-standing track record.

Repairs to All Common Single Ply Membrane Roofs
A leaking single-ply roof does not always need full replacement. Many issues start around details rather than across the whole roof sheet.
Membrane punctures and splits
Damage from access, plant, tools, movement, impact or ageing can often be repaired once the membrane type and condition are understood.
Failed laps and welds
Open laps, poor previous repairs, failed welds or unsupported joints can allow water below the membrane.
Detail leaks
Upstands, outlets, rooflights, penetrations, parapets, flashings, plant supports and edge details are common weak points.
Important repair note
Not every membrane can be repaired in the same way. PVC, FPO, TPO and EPDM behave differently, and old membranes can be affected by age, contamination, previous coatings or incompatible materials. Modern Roofing checks the existing roof before recommending a repair method.
Why Modern Roofing Believes Sika Is the Best Single Ply Membrane Partner
We repair many membrane systems, but for new single-ply membrane specifications we wanted the strongest route for the type of work we put our name to. For Modern Roofing, Sika is the best single-ply membrane partner because it gives clients strong technical backing, proven products, robust detailing support and long-term confidence.
Strong product range
Sika’s single-ply membrane range includes Sika Sarnafil and Sikaplan systems suitable for both new build and refurbishment work.
Technical support
Industrial roof projects often need correct detailing, drainage, wind uplift consideration, insulation build-up and manufacturer guidance. Sika gives a strong technical route for this.
Long-term confidence
Sika Sarnafil systems have independent BBA assessment for specific systems and Sika offers guarantee routes depending on the system, contractor and project requirements.
Our position
Modern Roofing has not chosen Sika because other membranes are poor. Bauder, Protan, IKO, Alwitra, Renolit, Fatra and EPDM systems all have their own place in the market, and we can repair many of them where the existing roof and repair method are compatible. We chose Sika because, in our opinion, it is the best partner for commercial and industrial single-ply membrane projects where we are responsible for the specification, detailing, finished system and long-term client confidence.
Single Ply Membrane Types We Commonly See
Different single-ply membranes can look similar from a distance, but they are not all the same. The repair method, welding approach, preparation and compatibility depend on the membrane type and the condition of the existing roof.
PVC membranes
Common on commercial flat roofs and often hot-air welded. Examples include many Sika, Bauder, IKO, Renolit and Fatra membrane systems.
FPO / TPO membranes
Used on many modern flat roofs. These require compatible preparation, detailing and repair materials.
EPDM membranes
Synthetic rubber single-ply systems are common on flat and low-slope roofs and need a different repair approach from PVC or FPO membranes.
Repair, Refurbish or Replace a Single Ply Roof?
The cheapest repair is not always the best answer, but full replacement is not always necessary either.
| Option | When it makes sense | What Modern Roofing checks |
|---|---|---|
| Local repair | Small punctures, failed laps, isolated detail leaks or local damage. | Membrane type, condition, contamination, weldability and cause of water ingress. |
| Detail refurbishment | The field membrane is usable but outlets, upstands, rooflights, plant or edges are failing. | Weak details, drainage, movement, compatibility and whether repeated leaks are linked. |
| Overlay or recovery | The existing roof may be suitable for a new waterproofing layer without full strip-off. | Moisture, structure, insulation, adhesion/fixing route and manufacturer requirements. |
| New Sika system | The roof needs a properly specified long-term single-ply membrane solution. | Deck, vapour control, insulation, drainage, wind uplift, details, access and guarantee route. |
