Project Overview:

SIGA Natural Slate was specified for a major £20m re-development by the PJ Livesey Group at Manchester Metropolitan University’s former Didsbury campus. When completed later in 2018, pitched roofs to 57 houses and 36 apartments will all be roofed in SIGA 112S slates from the Excellence range.

In Detail

Designed by Calder Peel Architects, these new homes at St James’s Park are part of the developer’s scheme to regenerate this 17-acre heritage site by mixing heritage buildings and new homes in a mature setting.

PJ Livesey places an emphasis on getting the balance right between conservation and a more contemporary approach to bespoke new build housing and includes outside space, high quality architecture and the retention of trees.

The choice of slate roofing materials was architecturally sensitive. SIGA 112S was selected an excellent match for Welsh Blaenau Ffestiniog slate which has been used predominantly in the Manchester area and surrounding towns but is now extinct.

Approved for use in the Snowdonia National Park, SIGA 112S is sourced from some of the finest slate seams available in Spain. An excellent colour match, it combines exceptional durability with outstanding workability, along with minimal sorting requirements. The texture and appearance are typical of a first-selection La Bana Hebra slate, with a fine vertical grain. SIGA 112S natural slates are guaranteed for 75 years and are NHBC approved.

SIGA 112S 500 x 250mm slates with a head lap of 100mm were chosen to meet the “moderate” exposure rate required for this area of Manchester.

Project Outcomes

Graham Cobain of NFRC members, Cobain Roofing said:

“We have a long-standing relationship with SIGA. To fulfil our contracts on time and to budget, we look to source SIGA slates from SIG Roofing branches. The project ran smoothly without logistical or quality issues arising.”
