At the new 30,000 sq ft District HQ for Great Britain’s largest union, Unite, a comprehensive refurbishment – including a new roofing installation – was required. BriggsAmasco, the UK’s leading waterproofing and roofing specialist, was appointed to install 600m2of single ply roofing membrane and create a complex zinc-lookalike rooftop facade.

After taking control of the former Transport and General Workers’ Union (TGWU) building in Liverpool, Unite ordered a complete renovation to bring the building up to standard. Following ten years of being vacant and as part of an extensive repair programme, an entirely new roofing system was provided by BriggsAmasco.

The company started the project by covering all of the main roofs in SpectraRoof TPE. The main roof works proved straightforward for the company, with the new build decking and single ply system installed onto an extra floor that had been added to the new metal frame. The metal deck system was installed across the entire 600m2roof area, followed by the SpectraRoof TPE membrane and 100mm thick insulation.

As the stand-out aesthetic aspect of the job, BriggsAmasco provided exceptional detailing around the building’s high level perimeter to create a stunning vertical zinc-lookalike facade. This consisted of Spectraroof TPE Lead Grey membrane with a standing seam welded on to create a mock seam, designed and installed by the company’s specialist team.

Now complete and renamed Jack Jones House – after the former trade union leader and General Secretary of TGWU – all aspects of the roofing contract were completed to the highest standard. The high quality refurbishment project at one of the city centre’s landmark redevelopments will form an important part in the city centre’s regeneration.
