Sector: Commercial
Project Value: £120,000
Project Overview
Reroofing of a four-storey tenant-occupied commercial building for Griffin Housing Association, carried out from a full scaffold with a temporary roof maintained throughout. Existing asphalt, cork insulation and the timber deck were renewed, with new insulation, mastic asphalt and leadwork installed, and the mansards re-clad in new slates over a new felt and batten structure.
Works included:
Full scaffold to all elevations with temporary roof to maintain weathertightness
Removal and renewal of existing asphalt, cork insulation and timber deck
New insulation, two-coat mastic asphalt, solar reflective paint and leadwork
New lightning protection system
Mansards re-clad in new slates over new felt and batten structure
Specialist removal of asbestos-containing slates
Approach / Key Challenges
The building remained tenant-occupied throughout, so a temporary roof was maintained at all times to keep the property weathertight. Asbestos was identified in the existing slates during strip-out and removed by a specialist contractor, coordinated with the CDM co-ordinator and Building Control.
