The Problem


The 1,000m² metal roof at Poundland's Colchester store had reached the end of the service life of its existing coating system. Corrosion had begun to develop around the mid laps, cut edges and fixings, while sealant across the mid laps and skylight details had deteriorated.

The roof required refurbishment before deterioration progressed further and resulted in water ingress or costly sheet replacement.

Key issues included:

  • Existing coating system reaching the end of its lifespan.
  • Corrosion affecting cut edges and sheet overlaps.
  • Fixings becoming a potential source of leaks.
  • Failed sealant around mid laps and skylight details.
  • Risk of significant disruption if repairs were delayed.
