The winning entry in the NFRC Roofing Awards 2013 Roof Sheeting Category is the £35 million roof refurbishment at London Victoria Station.

Installed by Everlast Group, the replacement roof featured the R46 profile by Tata Steel in double-sided Colorcoat HPS200 Ultra®, with a Goosewing Grey finish on the external face and a Straw finish on the internal face. The R46 profile was chosen due to its ability to span approximately 2.8m from purlin to purlin.

On the concourse, the existing felt roofing laid on timber purlins was replaced by steel purlins and C19 profile in Colorcoat HPS200 Ultra® in Goosewing Grey, laid over purlins at nominal one metre centres, with an internal PM13 profile in Colorcoat HPS200 Ultra® in Straw, providing a like-for-like tongue and grooved boarding effect when viewed from the underside.

R46 profile was fitted to the two approximately 40-metre span, over 100 metre long main barrelvaulted roofs, to a 26 metre radius curve, incorporating stippolyte obscure glazing, to match the original patent glazing system. The existing translucent corrugated sheeting was replaced with stippolyte glazing mounted within a patent glazing bar system. The internal colour choice of Straw was arrived at following extensive research into the concourse colour scheme, to ensure that replacement colours accurately interpreted the original Victorian paints.

The Roofing Awards have now entered their eighth year. Formerly known as the NFRC Awards, they have become an industry-wide competition that recognises and rewards outstanding standards of workmanship and safety within the roofing industry.

The awards were presented by the BBC Breakfast presenter Susanna Reid at the Roofing Awards Congress Lunch held at the Hilton Metropole, London on Friday May 17th.
