Working with Contour Roofing, Sika’s Sarnafil membrane was installed at Ewart Grove, a residential development by Paul Simon Homes near Wood Green, London.

Ewart Grove required a high-performance roof with a striking aesthetic result to match the contemporary luxury flats within.

The roof had an extremely intricate design, including two barrel roofs and a large, unique triangulated tower at the front.

Originally the specification for the 400m2 area called for a metal roof but the cost implications of this meant that another solution was needed.

Contour Roofing sought to prove that the roof could indeed be covered using a high quality single ply membrane, if the correct product and level of expertise were applied.

Having worked with the product before it was decided that Sika Sarnafil would be an ideal finish for the project and be within budget.

Contour quickly presented a new bespoke specification; an adhered system using Sarnafil G410-15ELF Lead Grey with a polyester fleece backing as the main roof sheet for a flawless result and Sarnafil G410-15EL Lead Grey for all the detail work flashings.

Working closely with the carpenter, Contour had to ensure that the plywood deck was spot on so that the membrane could be laid smartly and correctly. Absolute attention to detail and skill were required to make sure the membrane was flush with the substrate below.

Décor profiles were used to imitate the standing seams of a metal roof, which is what the original designs had envisaged.

Sikalastic was used for the guttering when the space was just too tight for single ply, demonstrating the compatibility between Sika’s various roofing products. Both the Sika Sarnafil and Sika Liquid Plastics systems were awarded a 20 year guarantee.

The Sika Sarnafil membrane mirrors the metal look that the client originally desired, matching the luxury feel the client wanted to achieve throughout the building.
