As part of a £4.1 million re-development project at the prestigious York Theatre Royal, BriggsAmasco Leeds and Sika Liquid Plastics delivered an outstanding roof refurbishment, requiring extremely complex detailing around 31 new roof lights.

The area that presented the biggest challenge for BriggsAmasco was the flat roof above the atrium of the theatre, a grade ll* Listed 1967 extension to the building designed by renowned modernist architect, Patrick Gwynne. This roof was of particular concern as it had an original 50 year old asphalt covering, which had clearly come to the end of its life.

Despite the roof being only 100sq m in size, the area had an incredible 31 roof lights to replace and work around. With so many roof lights in a small place, the detailing lent itself to a liquid product, and Sika Liquid Plastics worked alongside BriggsAmasco and building surveyors, W R Dunn, to make sure the roofing solution would be in keeping with the buildings heritage, while offering a stunning new feature in the atrium roof.
