At a dizzying 160m (525ft) tall, London’s distinctive Walkie Talkie building required an exceptional roofing solution. Fenland Roofing and Sika Sarnafil single ply were up to the challenge. Cambridge-based contractor Fenland Flat Roofing was required to provide a lightweight walkable roof area for the access walkways and perimeter edges of the glazed roof to the garden and restaurant. The roofing product had to be carefully selected as it needed to curve in two directions due to the unique design of the building.

Sarnafil G410-12EL single ply provided the perfect solution to this design criteria, thanks to its excellent flexibility and weldabilty, while offering outstanding resistance to weathering, including permanent UV irradiation. This was installed in Lead Grey to the BMU Track and covered with SarnaTred walkway tiles, allowing durable and slip resistant access for maintenance workers – a vital safety consideration.

High skill levels were required to overcome the various tricky details on the roof and the team had to interface with multiple trades. Internally the Walkie-Talkie provides a mixture of 13,000sq ft of retail space and 680,000sq ft of top quality offices with panoramic views of London. It is designed to have a BREEAM excellence rating.
