Your roof is one of the most important parts of your home or building, and one of the most costly to repair if it’s done poorly.
The Roofing Association of New Zealand (RANZ) represents more than 300 professional roofing businesses nationwide. RANZ members are required to meet clear entry criteria and commit to recognised industry standards, ongoing training, and professional conduct.
Choosing a RANZ member means choosing a contractor who is part of a wider professional framework, one that supports quality workmanship, regulatory compliance, and better outcomes for homeowners.
When it comes to protecting your property, choosing a recognised professional isn’t optional. It’s essential.
What sets RANZ Members apart?
Verified Workmanship Standards RANZ members must meet defined workmanship criteria to gain membership. Their work is expected to align with the New Zealand Building Code and manufacturer installation requirements, helping ensure your roof is built properly, not just quickly.
Accountability & Professional Conduct Members are bound by RANZ’s Code of Ethics and Conduct. If a serious issue arises, RANZ offers a dispute resolution process to support fair outcomes, an added layer of accountability you won’t get with unverified operators.
Compliance & Correct Documentation RANZ members understand and comply with relevant building legislation and regulatory requirements. This includes providing essential documentation such as Records of Work for restricted building work, helping protect your compliance position and product warranties.
Trained & Experienced Teams RANZ members invest in ongoing training and professional development. Many employ NZQA-qualified staff and stay up to date with changes to codes, standards, and legislation — so your roof reflects current best practice.
Strong Health & Safety Practices Roofing is high-risk work. RANZ members operate with established Health & Safety systems and follow recognised industry standards, helping keep workers, and your property, safer.
A Mark You Can Trust The RANZ Member logo is a trusted industry identifier. It signals a roofing business that is connected, informed, and committed to doing the job properly.
Choose with confidence.
Roofing is a specialist trade, and the quality of the work has a direct impact on the safety, durability, and long-term performance of your building.
A RANZ member is not just a contractor, they are part of a professional association that sets expectations, supports best practice, and promotes accountability across the industry. They are required to operate within recognised standards and to keep their knowledge current as building requirements and products evolve.
When you choose a RANZ member, you reduce risk, increase certainty, and engage a business that takes its responsibilities seriously.
For work you can trust, choose a RANZ member, and protect your investment with confidence.
