Rubik’s cube solved by Contour Roofing and Sika Sarnafil

Following last year’s NFRC Roofing Awards win, Sika Sarnafil Registered Contractor Contour Roofing, has once again been recognised for its outstanding work, making the shortlist in the Single Ply category.

With the success of its previous award-winning project, Ewart Grove, a London residential new build, Contour was called on again by client Paul Simon Homes to offer a premium waterproofing solution for Cheltenham House. Another new build project in London, comprising of 11 luxury apartments, the entire roof and vertical works are shaped like a Rubik’s Cube – a puzzle that was no match for Contour Roofing’s problem solving skills.

Originally specified with metal cladding, the client wished to replicate this look for less cost, while achieving the same beautiful finish. Jonathan Woods, Managing Director at Contour, once more proved that Sarnafil’s single ply membranes can accommodate the most complex builds, while offering the client one of the most robust extensive product guarantees on the market.

Contour worked closely with Sika Sarnafil to generate a bespoke specification with Sika Sarnafil’s recently launched Self Adhered membrane in lead grey, and decor profiles to emulate metal seams. Custom-made Sarnametal details were cut and fabricated to accommodate the various angle changes on the roof, including vent grills to the base of the cube.

Sarnafil’s new spray-applied adhesive Primer 610 was quickly and carefully applied to all the vertical areas, to accommodate the application of the Self Adhered Membrane. The weight of each drop (over 18kg) proved extremely challenging, and had to be secured with a peelstop, and fixed at every point with stainless steel SFS fixings. The décor profiles were installed with upmost precision and careful measurement, creating symmetry and uniformity on all four sides of the building.

Jonathan Woods explained:

“Every single detail on this project has been carefully planned before application of the products. Coupled with the wealth of experience invested by our contract manager and award-winning fitters, the project was finished to perfection.

“Sarnafil advised us to use the new Primer 610 and Self Adhered membrane and helped us to understand the product with demonstrations at its training academy and our offices. Change is always tough, certainly with experienced fitters, but we insisted that the Self Adhered membrane was paramount for the success of the roofing works at Cheltenham House. The product is quick and easy to use and leaves a beautiful finish to any application it’s used on.”

Commenting on the delivery of the project, Carly Tang of Paul Simon Homes said:

“After the huge success of Ewart Grove, we reached out once more for the services and expertise of Contour and again they did not disappoint. We were able to offer a project well under budget and on time, thanks to the hard work of the team and the innovative Sika Sarnafil Self Adhered product.”
