In late August this year the newly-moved-in owners of a new build property in Hertfordshire could look out from their roof terrace to see a field of yellow provided by the planting of a green, or natural roof, installed as part of their ambitious homebuilding project.
The new home replaced an 80’s derelict bungalow and is located in an area of outstanding natural beauty, a short walk from one of the oldest motte and bailey castles in England. In some areas regulations and incentives make it desirable to place a green roof on a new building and, in this case, it seemed a natural choice to specify a roof that paid tribute to the stunning, surrounding natural features and landmarks.
While the main house has a slate tiled roof one section undulates, like the rolling hills behind the house, creating separate roof areas; the green roof covers the main turret, which stands at the front of the house, and a small roof terrace which is midway along the long roof stretch dropping down to a small additional roof.
Roof Technology, a Roof Assured by Sarnafil approved installer, was commissioned by award winning builder contractor Pearson Building to install the roofing on these three areas, combining the high performance credentials of the Sarnafil roofing membrane with the natural look of a sedum matting.
Peter Lucek, Managing Director, Roof Technology (rooftechnology.co.uk) said: “The green roof makes a strong statement within the high design credentials of this innovative new build project. The fact that Pearson Building selected us, an approved installer of the Sarnafil single ply membrane, to work on such a high profile project is testimony to the quality and high performance of the work we carry out”.
Sarnatherm roof insulation was laid on the primed roof deck of all three areas over which was applied a Sarnafil single ply waterproof membrane and a protection sheet was laid on the turret and terrace area. Drainage, a river stone perimeter and growing medium were then laid ready for the Sedum matting.
All Sarnafil products used in the installation are covered by a 15 year guarantee and the Sarnafil single ply membrane has been independently assessed by the BBA to last, in their opinion, in excess of 40 years.
