Flat Roof Project Requirements

The flexible, easy-to-apply, aesthetic properties of Sika’s watertight singleply membrane proved the ideal solution for a stylish and unusual roof design – the crowning glory of a new, multimillion pound community church.

The £4.5million C3 Centre in Cambridge was built to host community events as well as serve as a place of worship. The two-tier building’s architecturally striking feature is its ‘fantail’ roof. Tapering to a point at one end, the roof’s design presented a challenge to Farrans Construction, main contractors of the church building project.

The company required a roofing system which not only offered the optimum watertight performance; it had to complement the structure’s eye-catching design. With Cambridge Flat Roofing specified to carry out its installation, the Sika-Trocal® SGK system met the contractor’s brief to perfection.

Sika Liquid Roofing Solutions

Suitable for both new build and refurbishment applications, in both warm roof and cold roof construction, Sika-Trocal® SGK is the best-cost performance bonded membrane for use on all types of substrates. Offering excellent flexibility and high resistance to ageing and weathering, Sika-Trocal® SGK ensures a long-lasting, low maintenance roof covering.

"The roof looks pretty spectacular and certainly offered a challenge in terms of its construction. There’s no doubt the Sika-Trocal® SGK system’s specification aided the building process. It not only looks as good as it performs, it was simple and quick to install. It made a potentially tricky installation, quite straightforward." Wayne Farrington, Director at Cambridge Flat Roofing

Work on the church roof started in March 2015. As well as the installation of Sika-Trocal® SGK on the 1,500m2 main roof, Cambridge Flat Roofing applied Sika-Trocal’s Type SGmA single-ply membrane as part of a sedum roof buildup on a lower area of the building.

The fully-adhered Type SGK roofing membrane is approved by the British Board of Agrément (BBA) to have a life expectancy in excess of 35 years. Its easy application ensured the church’s stunning roof was completed ahead of the client’s strict eight-week deadline to ensure this gloriously-designed building will remain watertight and functioning as a vital community hub long into the future.
