Seamless Waterproofing Solution for Commercial Roof Leak

The Issue: Ongoing Water Ingress to Commercial Roof

A commercial client approached us with concerns about persistent water ingress affecting their building. While roof leaks can often lead to assumptions of full replacement, a detailed inspection revealed that the issue could be effectively resolved with targeted remedial works instead.

The primary cause was poor drainage due to a blocked gulley, combined with vulnerable detailing around the roof structure that required reinforcement to prevent further water penetration.

Following a full assessment, we recommended a practical, cost-effective solution designed to stop the leak immediately while protecting the roof structure with minimal disruption to daily operations.

Works Completed

Our roofing specialists carried out a series of focused remedial works to restore drainage and install a reliable waterproofing system. The project included the following:

Clearing of the roof gulley to reinstate proper water flow and prevent pooling

Installation of a Fibre 10 liquid waterproofing system beneath the slates and extended up the upstanding curb to create a seamless, watertight barrier

Targeted application of the waterproofing system to address vulnerable areas prone to ingress

Raking out and repointing of all localised coping stone joints to strengthen exposed sections and prevent further deterioration

All works were completed efficiently, ensuring minimal disruption to the client’s business operations.

Outcome

The roof is now protected by a strong, seamless waterproof barrier that immediately stops water ingress and significantly reduces the risk of further issues.

By opting for a repair and protection solution rather than a full roof replacement, the client benefited from:

•  Fast installation
• Cost-effective solution
• Immediate protection against leaks
• Minimal disruption to business operations

This project highlights the importance of experience in determining whether a roof requires repair, protection, or full replacement—often saving clients significant time and cost while still achieving a long-lasting result.
