Project case study · Roof remedial works

From blocked drainage to a maintainable roof.

A practical remedial programme focused on drainage, vulnerable perimeter areas and clear photographic evidence of completion.

Residential blockSloughDocumented completion

Accumulated growth, debris and restricted drainage.

Moss, vegetation, silt and debris had accumulated across the roof, with blocked outlets and weathered perimeter areas increasing the risk of poor drainage and local water ingress.
