About NZRS

The New Zealand Roofing Systems (NZRS) was established through the merger of three companies: H2OFF Waterproofing, which traces its origins back to 1976 in South America and established itself in New Zealand in 2013; Dunedin Roofing Systems, which began operations in Dunedin in 1987; and TALY Roof Maintenance and Leak Repair Services. This unification has significantly benefited our clients, offering a one-stop shop for all their roofing, flashing, and membrane waterproofing needs. Clients enjoy the convenience of a single warranty for all completed work, eliminating the complications of overlapping products and warranties from multiple companies.

Today, NZRS operates eight branches across New Zealand and plans to open four additional branches by the end of 2028. At NZRS, we consider our people our greatest asset. From management and quality control teams to our skilled technicians, we function as a cohesive unit, always prioritizing client satisfaction. Renowned for our reliability and exceptional workmanship, NZRS is a trusted name in the industry.

With a team of over 100 technicians in New Zealand and access to more than 20 overseas experts who assist with workload demands as needed, we are confident that NZRS affiliated companies offer premier roofing and waterproofing solutions. Whether tackling a small repair or a multi-million-dollar project, we possess the expertise and capabilities to deliver outstanding results.
