Flat Roofs In Medway: Repair Or Replace?

5 min read

How to tell whether your Medway flat roof needs a local repair or a full replacement — plus the covering options and what suits each job.

Flat roofs are everywhere in Medway — on extensions, garages, dormers and commercial units across Chatham, Gillingham, Strood, Rainham and Walderslade. But how do you know when to repair and when to replace?

Signs A Repair Will Do

  • Localised leaks around flashing or upstands
  • Small blisters or splits in otherwise sound felt
  • Ponding water that can be corrected with new firings
  • A roof under 10–15 years old in generally good condition

Signs It's Time To Replace

  • Widespread cracking, splitting or felt shrinkage
  • Repeated leaks in multiple spots
  • Sagging decking or rotting timber underneath
  • The roof is 20+ years old and nearing the end of its life

What Are The Options?

  • EPDM rubber — hard-wearing, seamless, ideal for domestic extensions
  • GRP fibreglass — smooth, durable finish, great for balconies and walk-on roofs
  • High-performance felt — a cost-effective, proven system
  • Liquid coatings — excellent for awkward shapes and overlays
