A healthy roof is essential to safeguard your building from New Zealand’s harsh climate. Gunac | Waterproofing Specialists provide expert roofing services to resolve leaks and prevent costly damage.

Our experienced team offers roof inspections, repairs, and replacements for commercial, industrial, and residential properties. As members of the Roofing Association of New Zealand, we deliver trusted, high-quality solutions.

Green roofs, or ‘living roofs’, feature vegetation or ballast over a waterproof membrane to manage water retention and prevent leaks. We install anti-root membranes to protect buildings from root penetration. Green roofs offer aesthetic appeal, usable space, natural insulation, and reduced rainwater runoff – making them a smart, sustainable choice for new builds or roof redevelopments.
