Achieving the impossible with Sika Sarnafil I
n a complex new build roofing project that was deemed almost impossible, Contour Roofing stepped up to the challenge with
tial development minutes from Wood Green tube station, required a high-performance roof with a striking aesthetic result to match the contemporary luxury flats within. Located in a prominent position at a fork in a road, the roof can be seen when travelling up to the building, as well as from the upper floors of surrounding buildings. With its extremely intricate design, including
two barrel roofs and a large, unique triangulated tower at the front, the project presented a real challenge. Originally the specification for the 400m2
area called for a metal roof but the cost
implications of this meant that another solution was needed, and fast. It was thought that such a complex roof design could not be done, especially with the time and
budget available. However Jonathan Woods, director at Contour Roofing, alongside senior contracts manager, Lee Clift, 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. Jonathan and Lee met with the architect and the
director of Paul Simon Homes to discuss amending the roofing specification. Jonathan explained: “With our previous experience of Sika Sarnafil products, we knew that we could get the perfect finish within budget. In partnership with Sika Sarnafil we 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.” The installation was very challenging, with
various shapes, details, upstands and intricate sections to cover. 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 project impressed the judges of the
upcoming NFRC UK Roofing Awards and has been shortlisted in the Single Ply category. The winners will be announced later this month.
