Roof Overlay Systems

A roof overlay is a cost-effective alternative to full roof replacement, allowing a new roofing system to be installed directly over the existing roof. This method strengthens and weatherproofs the building while avoiding the disruption of a complete strip-out.

Ideal for industrial and commercial sites that wish to remain operational; roof overlays minimise downtime, reduce waste, and improve thermal performance. The system is carefully designed to enhance structural integrity, extend roof lifespan, and bring the building up to current performance standards — all while keeping your facility protected throughout the works.

When Is a Roof Overlay Suitable?

A roof overlay is suitable when the existing roof structure remains fundamentally sound. This includes situations where the roof covering has reached the end of its service life, but the underlying deck and structural elements are in good condition. Overlays are often ideal where leaks are localised, insulation performance needs upgrading, and disruption to a live site must be kept to an absolute minimum.
