Newark - Flat Roof Remedial Works

The Brief

The existing flat roof at the Newark branch had reached a stage where a full refurbishment was required to improve its long-term weather protection and ensure compliance with current Building Regulations.

The existing waterproofing system, insulation and associated roof details had reached the end of their serviceable life, with the roof requiring complete renewal to improve thermal performance, waterproofing and the overall integrity of the structure. In addition, the existing roof safety systems, handrails, anti-climb barriers and drainage required inspection, refurbishment and reinstatement as part of the project.

The client required a comprehensive roofing solution that would provide a durable, fully compliant waterproofing system whilst minimising disruption to the operation of the branch.
