Waverley Court

Our purpose

As one of the UK’s leading housing associations, the Guinness Partnership prides itself on providing high quality homes that meet or exceed current Standards. It is therefore committed to a continuous programme of maintenance and asset management across its 60,000 homes estate.

As part of that process, the 13-storey 1980s-built Waverley Court in Crewe was due for refurbishment, including new windows and heating for the 95 flats therein. An initial survey highlighted that the 1200m2 roof was failing and in need of upgrade to maintain its weathertightness.

Our in-depth roof report also identified that the insulation was below current standards. Safety on the roof for maintenance was also an issue: the existing handrail was originally erected as a temporary fixture, penetrating the waterproofing and providing inadequate rooftop security for working at height.

Our solution

The existing waterproofing had perished beyond useability. We advised complete strip of the existing back to the concrete deck, and building up a new thermally-efficient roof to meet current standards required under the Part L of current Building Regulations.

Our TA-25 W Flat Roofing System for warm roofs was installed by Approved Contractor Everlast as sub-contractor to the principle contractor, Wates. To address the poor falls on the roof, the insulation was tapered to the perimeter. We achieved an overall roof U value of 0.17W/m2K, exceeding the current Regulatory requirement of 0.18W/m2K. In line with Safe2Torch guidelines, our self-adhesive system was used to detail around roof penetrations for extractor fans and similar plant.

We highlighted and designed bridging details to maintain the fire integrity around compartment walls to comply with Part B3 of Building Regulations.

We designed a new, permanent and safe handrail system. This is fixed to the brick façade of Waverley Court, avoiding any penetration of the roof fabric and thus maintaining its integrity and watertightness, whilst minimising maintenance requirements.

“Langley’s expertise and attention to detail has enabled us to deliver on our ambition of providing homes that people want to live in.
