The existing roof covering consisted of a copper mansard roof which drained into a perimeter gutter with internal downpipes. The gutters were of a timber construction topped with a single ply membrane.
The single ply membrane had failed at the joints, allowing the rainfall from the copper mansard to enter under the membrane and ingress into the building. This caused severe water damage.
London Roofing stripped off the single ply membrane and replaced the wet and rotten timber with new Waterproof Board (WBP) ply. We then installed a cold applied liquid membrane. There were no hot works required, therefore eliminating any fire risk. The works were completed on time and within budget. On completion of the works the client was issued with a 20 year single point labour and materials guarantee, backed by the manufacturer.
