Project · Single Ply Membrane

Bingham Drive, Lyndhurst

We took this project on after the previous developer and roofer left halfway through, and put right both the flat roof and the pitched roof extension.

Location

Lyndhurst

System

Alwitra single ply, 120mm warm roof

Scope

Flat roof replacement, mono-pitch rebuild, tiled and lead works

The Project

Putting Right a Half-Finished Job

The flat roof had been installed in EPDM and was one of the worst we had seen in a long time, with water ingress across the roof area and details either installed incorrectly or left half done. The new pitched roof extension had been half started with the steels wrong.

We started with the flat roof, stripping off the existing EPDM rubber covering and fitting a new ply deck across the roof for a fresh, clean surface. As the developer had insulated from below, we then fully adhered an Alwitra single ply membrane to the new plywood. After finishing most of the roof and the new trim profiles, we took out the door leading on to the roof to complete the threshold detail correctly; it had previously been attempted with the door in situ.

We fully stripped and rebuilt the top mono-pitch roof, including new extensions on two sides. The flat roof area above this had a new 120mm insulated warm roof installed with a bespoke trim to suit the pitched detail. The lower tiled works were completely refurbished with a new build-up and reclaimed tiles to match the roof, and we installed all the new lead work and lead detailing.
