Westgate House, an office building located at Westgate, Halifax, was recently re-roofed using Trocal S, one of the single-ply roofing membranes from market leader Sika. The problem in the re-roofing was that the client required a cost-effective, watertight solution and specified that the re-roofing should not disrupt day-to-day business. The solution from the Trocal team and specialist contractor QM Roofing of Dewsbury was to overlay Trocal S on top of the failed roof to waterproof the structure without stripping off the existing roof.
