Sandell specified the R-MER LOC standing seam metal roofing system to overlay the existing roof structure. The penetration-free R-MER LOC profiles are designed with an innovative sliding slot connection and zip-free seam to provide a long-lasting and reduced maintenance solution for the Beresford Centre. By overlaying the failed metal roofing system with R-MER LOC, the Beresford Centre could mitigate high labour costs for an entire strip of the existing roof and avoid tonnes of unnecessary waste going to landfill.
As part of the design process, sheet gauge and wind loading calculations were carried out to ensure the new roof would remain secure and prevent damage from wind uplift in the future. Garland UK Approved Contractor, Aldworth Roofing Contracts, prepared the site, including the upstands and parapet, which were increased to match the height of the new build-up.
A vapour control layer was installed before the top hat subframe was mechanically fixed through the existing metal roof system to the purlins, followed by the Z profiles, which were mechanically fixed to the top hat profiles, running verge to verge in line with the existing purlins.
To improve the overall U-Value of the building, 260mm compressed to 240mm thermal insulation was applied before R-MER-LOC’s interlocking aluminium metal profile sheets were installed.
To finish the project, Aldworth Roofing Contracts replaced the existing soffits and fascias, and new gutter liners were installed on the existing gutters. All outlets were extended to ensure rainwater could be effectively transported away from the roof and building envelope to drainage.
