Durable Flat Roofing for Every Property

Flat roofs demand careful installation and maintenance to ensure long‑term waterproofing. We assess each roof using advanced tools, including thermal imaging, to identify weak points and leaks before recommending a cost‑effective repair or renewal.

Our Flat Roof Process

  1. Inspection & Thermal Survey: We identify leaks, cracks, or areas of pooling water.
  2. Surface Preparation: Existing materials are cleaned and primed to ensure a secure bond.
  3. Membrane Installation: High‑grade felt or GRP fibreglass materials are fitted for full waterproofing.
  4. Detail Work: Edges, outlets, and joints are carefully sealed to prevent future leaks.
  5. Drainage & Finishing: Falls and outlets are adjusted for proper water flow.
  6. Final Inspection: Every flat roof undergoes a water test before completion.
