Roof Strip & Rebuild

TK Maxx, Lewisham

Introduction

RML were proud to deliver this comprehensive roofing refurbishment at the TK Maxx store in Lewisham, forming part of our ongoing partnership supporting the retailer across multiple sites nationwide. The project required detailed planning, seamless coordination, and a combination of roofing systems to ensure both quality and minimal impact on day-to-day store operations.

Overview

RML were appointed to deliver a full roof refurbishment at the busy TK Maxx store in Lewisham. The project required a combination of strip and rebuild works, liquid waterproofing, and a two-layer felt overlay system all completed while ensuring the store remained operational throughout.

Scope of Works

The works were divided across three key roof zones, each requiring a tailored approach:

  • Area 2 (180m²) – Complete strip and rebuild of the existing roof. The structure was built up with new insulation and a two-layer felt system, incorporating a new purpose-formed gulley to improve drainage performance and long-term protection.

  • Area 3 (194m²) – Liquid waterproofing system installed using the LRS Advanced System. The process involved applying a VCL primer followed by two top coats. This method was selected due to the presence of mechanical ducting and plant equipment that restricted access for traditional felting, ensuring a seamless and watertight finish in tight areas.
  • Area 4 (650m²) – Two-layer felt overlay system using Danosa membranes, applied over the existing roof structure to enhance durability and provide a long-term, fully guaranteed waterproof solution.

Challenges & Solutions

Operating above an active retail environment presented logistical and safety challenges, particularly around customer and staff movement. Our team implemented a detailed phasing plan to minimise disruption, with all works coordinated during quieter trading hours where possible.

In addition, the presence of extensive rooftop ducting required a flexible approach seamlessly integrating liquid and felt systems to deliver a consistent, manufacturer-approved waterproof finish across all areas.

Results

  • Delivered on programme and to specification
  • Improved drainage and thermal performance through new insulated build-up
  • Fully watertight roof with extended manufacturer guarantees
  • Little disruption to store trading and operations
  • Exemplary workmanship across mixed roofing systems (LRS & Danosa)

Summary

This project showcases RML’s capability to manage complex multi-system roofing refurbishments within live retail environments combining technical expertise, strong site management, and close client collaboration to achieve a premium finish safely and efficiently.
