Flat Roof Overlay with Rhenofol CV – Commercial Road, Liverpool

Project Type : Roof Refurbishment (Overlay)

Product : Mechanically Fixed Rhenofol CV with Geotextile Separation Layer

Location : Liverpool, UK

Rubberseal is proud to have delivered the first UK roofing project featuring Rhenofol CV since its long-awaited return to the market. Rhenofol CV is back in the UK!  And what better way to mark the relaunch than with a flagship overlay installation on a large commercial property on Commercial Road, Liverpool.

Working closely with our approved contractor Apex Roofing Solutions and Elevate Technical, Rubberseal provided specification guidance, materials, and on-site support to ensure a smooth and professional installation from the outset.

Project Overview

The existing roof consisted of an ageing asphalt waterproofing system, which, while past its prime, remained stable enough to be overlaid. Prior to any works commencing, a full roof survey was conducted, including core testing and wind uplift calculations. The results confirmed that the existing roof structure was suitable for an overlay, which helped minimise disruption and reduce overall project costs.

To isolate and protect the new membrane from the asphalt below, a 200g/m² geotextile separation fleece was installed across the entire roof surface. This layer acts as a crucial barrier, allowing for thermal movement while enhancing system longevity.

System Specification

Rubberseal specified and supplied Rhenofol CV, a mechanically fixed PVC single ply membrane known for its strength, flexibility, and durability. With hot-air welded seams and secure mechanical fixings, Rhenofol CV forms a seamless and watertight system that’s built to last.

Our Business Development Manager Neil, supported by John Turner from Elevate Technical, visited the site to observe the installation and offer technical support—reinforcing Rubberseal’s hands-on commitment to quality delivery.

Why Rhenofol CV?

It’s no wonder Rhenofol CV is often referred to as the “Rolls Royce of single ply”—and now it’s available in the UK once again!

Conclusion

This project on Commercial Road, Liverpool, is a textbook example of how intelligent surveying, quality materials, and experienced partners come together to deliver a successful commercial flat roof refurbishment. With Rhenofol CV leading the way, Rubberseal continues to provide roofing systems that combine performance, value, and long-term reliability.
