1. Why is being a member of the Roofing Association of New Zealand (RANZ) important?

“RANZ Members are professional roofing specialists

Whether a residential dwelling or commercial/industrial property, installing a new roof, re-roofing or restoring and maintaining your roof system is an important investment.

Before you spend your money, make sure you:

  • Evaluate the roofing company or contractor who is quoting to do the work. A quality installation and competent workmanship by a specialist roofing company is essential to protect your investment.
  • Evaluate your product options. Ensure the materials used on your roof system are quality products suited to your location and environmental conditions and that all componentry e.g. fasteners and accessories, are compatible. Importantly, the materials should be backed by a sound durability product warranty from a reputable manufacturer, supplier or importer.
