• Profiled metal roofing — long-run steel, corrugate, and ribbed metal roof and wall cladding
• Membrane roofing — flat and low-slope systems

For Architects & Builders

We work closely with architects and main contractors on new build and alteration projects throughout Auckland. We understand the demands of a construction programme and the documentation requirements of a principal contractor.

What we bring to your project:

• Full technical documentation and specification compliance (E2/AS1, B2, Roofing COP)
• LBP supervision and written sign-off for all restricted building work
• H&S plans (SSSP, SWMS) formatted for principal contractor requirements
• Coordination with scaffolding and other sub-trades
• Post-completion reports suitable for Code Compliance Certificate applications
• Responsiveness to programme changes and site conditions

Warranty & Compliance

Workmanship warranty terms — typically ranging from 5 to 10 years depending on system type, substrate condition, and material selection — are confirmed in writing before work commences. Warranty terms are project-specific.

All installations comply with NZ Building Code (E2/AS1, B2) and the NZ Roofing Code of Practice. Building consent requirements vary by project and are assessed at consultation.

Solar-Ready Installation

We install with solar in mind. For clients who want the option to add solar panels in future — without disrupting the roof — we can factor solar readiness into the installation from day one.

This means thinking carefully about roof orientation and pitch, ensuring the roofing system and substrate can accommodate panel fixings without compromising weathertightness, positioning penetrations and cable runs in the right locations, and selecting profiles and fixing methods that allow for clean solar integration later.

It costs very little to do this upfront. Retrofitting solar to a roof that wasn’t designed for it is significantly more expensive — and in some cases requires re-roofing work to fix penetration and fixings done incorrectly.

If solar is on your horizon, tell us at consultation. We’ll confirm what’s practical for your roof and build it into the installation scope.
