Project description

This project involved investigating and rectifying persistent leaks around two recessed skylights. Our assessment identified that the existing flashing system had been incorrectly detailed, allowing water to bypass the flashings and enter the building.
We removed all debris from the affected areas and designed a new flashing system that extended beyond all critical leak points, ensuring water is safely diverted back into the roof pan before it can reach any vulnerable areas. While the new flashings may appear larger than standard, this is intentional and follows New Zealand metal roofing best practice to provide reliable long-term weatherproofing.
The completed installation delivers a durable, compliant solution that significantly reduces the risk of future water ingress and provides the client with confidence that the skylights have been flashed correctly.
