How do you refurbish a roof with 24 areas at varying levels and with various build-ups?
The SikaBit® 25-year system provided an ideal solution for this requirement at Portland School, Birkenhead—part of the Co-op Academies Trust since 2018.
Portland School’s claim to fame is that it was the first school attended by Everton and England footballing legend of the 1920s and 30s, Dixie Dean.
Safety precautions were even more important due to the live school environment, so working with a roofing provider that could offer a Safe2Torch system with self-adhesive membranes for torch-free zones was imperative. The quality and durability of the finish was also a key requirement of the project. The SikaBit® system, combined with the skills and experience of the team at roofing contractor, Holloway Cook Associates Ltd, answered this need with neat detailing across all roof areas.
Sika’s specialist Roof Refurbishment team was able to do a full site survey and provide a Safe2Torch plan for the installation. Holloway Cook stripped out all roofing areas, including removal of 19 layers of previous waterproofing systems from the oldest part of the roof, to reveal varying substrates including concrete, plywood and asphalt decks. They then applied the S-VAP HD SA air and vapour control layer (AVCL), followed by SikaTherm insulation.
Mike Holloway, Operations Director of Holloway Cook, said: “Our team is very experienced in bituminous membrane installations but the SikaBit system is new to us. We have been very impressed with both the ease of use and quality of finish the system offers, all supported by the service and technical support that Sika’s Roof Refurbishment division provides throughout the project.”
