Case Studies

Sunningdale Court & Midhurst Court

The owner of two identical 13 storey 1960s tower blocks in the centre of Maidstone selected the Langley Structures Flat to Pitched system to improve the long term value and aesthetics of the buildings as part of a general upgrade. Photovoltaic panels were also specified, to generate electricity for the communal spaces, so an array of sixty five PV panels, generating 21Kw, was installed on each building.  
 

These two challenging Flat to Pitched installations, at a significant height of over 45m, were undertaken by a Langley Approved Contractor. The task of lifting lightweight, 11m wide panels and swinging them into position at this height was a logistical challenge as well as being weather-dependent.  

Langley Structures designed all aspects of the re-roofing envelope including a lightweight pitched roof frame, a standing seam roof covering that facilitated fixing of the PV panels, plus the facias, ventilated soffit, vertical arrowhead cladding, and rainwater goods. 
 
The existing flat roof overlay was stripped down to the original mastic asphalt with the new pitched frame base angles fixed into the concrete deck with resin bonded fixings. The new roofs were required to cover various, multi-level rooftop structures such as the higher-level lift 
overrun, plant room and a high parapet of almost 2m. This meant that the apex of the new roofs was 4m above the original waterproofing level, adding to the installation challenges with regard to safe working at height. 
 
An added benefit for residents was that the new roofs incorporated external downpipes, replacing the original internal drainage system. This eliminates the risk of internal leaks from blocked rainwater pipes, and improves access for ongoing maintenance, without disruption to residents. The roofs were thermally upgraded using mineral wool insulation. The aluminium standing seam had a maintenance hatch built in, with fall arrest protection, to enable maintenance access to the roof.
