Standing seam metal roof refurbishment for Beresford Centre

Garland System

R-MER LOC

Sector

Commercial

The Beresford Centre is a mixed-use business centre in Basingstoke, comprising 21 workshop units and 8 offices for various trades, including car mechanics, packaging and press printing services to the local area.

Numerous patch repairs, including gutter linings, coatings and rooflight replacements, had been carried out over the years to stem the internal leaks. However, the persistent water ingress issues prevailed, affecting the fabric of the commercial units and causing significant tenant disruption.

Challenge

Technical Manager Daniel Sandell was instructed by the local authority to survey the site and specify a cost-effective solution to provide long-term waterproofing for the units.

Sandell’s investigations discovered the existing build-up consisted of a composite panel metal roofing system that had been suffering from corrosion and, despite numerous repair attempts, had come to the end of its waterproofing life cycle. The client required the proposed roofing system to be of a similar material to aesthetically match the standing seam metal roofs on the neighbouring buildings.

The Beresford Centre is an active commercial site and requires 24/7 access for tenants and business use. It was, therefore, essential to have in-depth logistic plans and meetings with SHW Building Consultancy to ensure minimal disruption to the site. This included installing two smaller bituminous membrane roof sections utilising the StressPly Signature system before upgrading the metal roof.

Solution

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.

The plant room comprised the R-MER CLAD system, a lightweight and hardy trapezoidal metal roof profile, including new insulation to achieve a 0.16 W/m2K U-Value.

Access walkways were laid in an alternate colour cap sheet for future maintenance. In addition, new access hatches and ladder systems, lightning conductors, cable duct flashing, and roof box housing were installed to finish the project.

Outcome

The 1,422 sqm project was completed on time and budget, with weekly site visits to assess the quality of installation and project progress. Tony Upfold (Sandell’s Technical Assistant) shared the weekly site inspection reports with the Beresford Centre building manager and the local authority via Garland UK’s RAMP (Roof Asset Management Programme) system to provide transparent updates to all parties.

A 0.18 U-Value was achieved, significantly improving the overall thermal efficiency of the building, and Garland UK’s market-leading 30 year Single-Point Guarantee was supplied to Beresford Centre on project completion, which provides full liability cover for the design, system and project installation.

Garland UK delivered professional support throughout the Beresford Centre roofing project, and the technical expertise from Daniel Sandell was an invaluable asset to ensure we achieved the best waterproofing solution for our site.

The storm exposed critical weaknesses in the original roof design, which had failed to cope with the site’s wind load demands. The closure meant immediate loss of revenue, reduced access to community leisure facilities, and growing urgency to reopen.

The replacement roof required complex engineering to match the building’s 40 metre wide dual-curved structure. Standing seam sheets up to 22 metres in length had to be precision-engineered off-site, with escorted delivery, timed road closures, and careful sequencing of work.

With only a small car park as the site compound, storage, crane operations, and contractor access needed meticulous planning. Moisture protection for the exposed structure was critical throughout, with temporary coverings installed until the new system could be sealed.

Garland UK Technical Manager Rob Wall specified the R-MER LOC standing seam metal system, designed for storm resilience, thermal efficiency, and long service life in marine climates. Its penetration-free, zip-free seam design enabled faster installation and allowed for thermal movement without panel distortion.

The system was tailored to the building’s complex geometry, with 22 metre top sheet runs and 18 metre lower runs. Approved contractor, Future Roof Leeds, carried out the works, reusing the existing perforated aluminium liner where possible to reduce waste and disruption.

A high-performance, foil-lined vapour control layer was installed, along with upgraded insulation and a breather membrane suitable for coastal exposure. Acoustic infills were also integrated to maintain internal sound control, enhancing the original system’s acoustic performance.

The 1,200 sqm roofing system was completed on time and within budget, restoring full functionality to SC2 Water Park and preventing further loss of income. Garland UK’s Roof Asset Management Programme (RAMP) now provides the Council with a complete digital record of the project, including inspection reports, guarantees, and maintenance guidance, giving estates teams full visibility for ongoing asset care.

Covered by a 30 year Single-Point Guarantee for design, materials, and workmanship, the Council has complete assurance that any issues will be resolved swiftly, without dispute or additional cost.

The reopening of SC2 Water Park has reinstated a much-loved leisure venue for residents and visitors, supporting local wellbeing, tourism, and economic activity. The storm-resilient design means fewer disruptions and reduced maintenance, and reliable year-round availability, even in challenging weather.

Robin Jones, Senior Building Surveyor at Denbighshire County Council, commented,

“The level of service from Garland UK has been first-class from start to finish. Rob and the team gave us confidence at every stage, from design to handover. The quality of the roof and the management of such a tricky site exceeded our expectations.”

Rob Wall, Technical Manager at Garland UK, added,

“This was a demanding brief in a harsh environment. The combination of curved geometry, extreme sheet lengths and complex logistics called for precision planning and strong collaboration. We’re proud to have supported the Council in getting this key venue back up and running.”
