The new build is part of Costco’s current UK expansion plans, which will see up to 45 warehouses built across the country.

Registered Sika Sarnafil roofing contractor Richmond Single Ply, based in Manchester, were specified for the job, recommended by the project’s cladding contractor, BC Roofing, who had worked with the contractors on an earlier Costco project in Leicester.

The size of the project and the quick installation time required resulted in the specification of the Sika Sarnafil S327-18EL membrane in Light Grey. Ideal for the job, the system is formulated for direct exposure to weather and is produced with integral polyester scrim reinforcement for high strength. Other installation details included perimeter detailing, roof light penetrations and various roof penetrations.

Built on their previous experience, Richmond Single Ply and BC Roofing’s working relationship resulted in a highly successful project without major setbacks, completed in approximately six weeks - four weeks under the set timeframe.

"For the size of the project and the time period with which it was completed, we couldn’t have finished with a more perfect job. From the client all the way down to Sika Sarnafil, the feedback has been enormously positive, and because of this we have been specified for future projects, alongside BC Roofing, with Costco in the future."
