Howard Evans Roofing and Cladding recently completed a major cladding project at the Iceland Food Warehouse in Wakefield.
The building, a former Tesco, was being converted into a new Food Warehouse, a concept from Iceland that offers customers a warehouse-style shopping experience, allowing them to buy in bulk and benefit from significant savings.
The project involved coordinating with fit-out contractors Spacefit, who were responsible for the store’s internal conversion, and a crane company tasked with removing machinery from the roof where two large wells were situated.
The roof presented several issues, including corrosion, peeling finishes, clogged gutters, and failing details. Given these conditions, Howard Evans recommended overcladding the roof areas to provide a durable and reliable solution.
The main roof and canopy were composite cladded and drained via external gutters. These areas were aged, showing signs of corrosion and deterioration.
Previous attempts to treat cut edge corrosion had been executed poorly, leading to peeling, while spot corrosion was visible across various roof sections. The plastisol finish had peeled in many places, exposing bare steel. The gutter system required attention. It was lined with plygene and clogged with plant growth and debris.
The roof lights were sheeted over, using plastisol cover sheets, and the detail around the well roof areas had deteriorated, with failing liquid treatments. The well roofs, made of single ply, were in poor condition, with splits and holes, clogged gutters, and debris accumulation.
As the well areas were no longer needed for plant equipment, we recommended covering them with the new overclad
system. To ensure the longevity of the roofing solution, the team installed a 10-year insurance-backed guarantee on both the canopy and main roof areas, as well as the two well roof areas.
The team erected a working platform scaffold for safe access to the site, complete with a handrail for edge protection. A support bar system was installed and fixed to brackets in a grid pattern across the roof.
Between the support bars, 160mm glass fibre quilt insulation was laid. Hornsey Steel 0.7 plastisol-coated steel sheets were then secured to the support structure using TEK screws and caps, with filler pieces added to the top and bottom of the sheets for a secure finish.
The project has been completed within budget and finished two weeks ahead of schedule. Regular inspections and maintenance have been recommended to ensure the longevity of the new roof system and prevent similar issues from arising in the future.
All works are covered by a full warranty, providing peace of mind for the client.
