About Flat Roof Repairs

A small problem on a flat roof rarely stays small for long. Leaks, splits in the membrane, blistering and standing water can all let moisture into the building if left - so we aim to get out promptly, diagnose the cause, and carry out a lasting repair rather than a temporary patch.

  • Prompt call-outs across Dorset
  • Leak detection and diagnosis, not just patching
  • Repairs to GRP, EPDM, felt and asphalt flat roofs
  • Fixes for ponding water, blistering and split membranes
  • Honest advice on repair versus replacement
