NZ Manufacturer has profiled the rise of Guardian Steel and the wider shift toward a more open, competitive building-products landscape. The feature traces how Roofbuddy’s new roll-forming business is giving the roofing sector something it hasn’t had in decades: real choice.
The story makes clear why this matters. For years, both homeowners and roofers have had to work within a near-monopoly steel supply chain. Guardian Steel steps into that space with compliant, locally built machinery, internationally proven coil, and a system that plugs directly into the Roofbuddy platform. The result is steadier supply for tradies, clearer pricing, and an end-to-end process that’s actually accountable from quote through to quality checks.
With more than $80 million in roofing work transacted through Roofbuddy and an average saving of $2,728 per job, the piece shows how vertical integration can push those gains even further; fewer delays, fewer surprises, and more consistent standards across the board.
NZ Manufacturer also highlights the bigger picture: New Zealand’s ageing housing stock and the real public health implications of cold, tired roofs. More competitive materials that still meet the Building Code make it easier to upgrade older homes, which is essential when half the country’s houses were built before 1980.
It’s a grounded look at how competition, practical tech, and clear standards can lift outcomes for the whole sector; not just in theory, but roof by roof.
