Specialist metal roofing is a discipline.
It requires more than familiarity with profiles or fixings. A true specialist understands how materials behave over time, how buildings move, and how environmental forces compound failure at weak points.
At Onyx Roofing, specialist capability includes:
This level of execution is essential for architecturally designed homes, commercial buildings, and exposed coastal properties where failure is not an option.
We’re a team of hardworking Kiwis dedicated to delivering top-quality roofing solutions across Auckland. As a small business with big ambitions, we’ve built our reputation on honesty, craftsmanship, and a commitment to getting the job done right.
From new roof installations to full roof replacements and guttering, we bring the same level of care and precision to every project, no matter the size. We believe in using the best materials, industry-leading techniques, and a down-to-earth approach that keeps things simple and stress-free for our clients.
Converting legacy roofing systems – tile, membrane, or asbestos – requires more than replacement.
We specialise in complex re-roofing projects, where structural load reduction, modern drainage design, and upgraded weathertightness detailing must be addressed simultaneously. High-tensile metal systems offer superior strength-to-weight ratios, but only when correctly engineered and installed.
Our approach ensures the new roofing system integrates seamlessly with the existing structure while delivering long-term performance improvements.
Roof failures are rarely caused by the sheet – they occur at the junction.
We design and fabricate project-specific flashings, gutters, and rainwater systems to manage water flow across complex roof geometries. Valleys, parapets, penetrations, and wall interfaces are resolved with purpose-built detailing rather than generic solutions.
This level of precision is fundamental to specialist metal roofing and is critical to preventing future water ingress.
Roofing performance does not stop at the roofline.
We deliver integrated metal wall cladding systems that align structurally and visually with the roofing envelope. This unified approach improves weather resistance, architectural continuity, and durability, particularly in exposed environments.

We begin with a technical assessment of architectural plans, environmental exposure, and risk factors. Where required, we collaborate directly with architects and designers to refine detailing and ensure system compatibility.

Each project receives a purpose-matched roofing system, selected for corrosion resistance, movement control, pitch suitability, and visual outcome. No assumptions or generic specifications.

All critical weathertightness work is executed under Licensed Building Practitioner (LBP) supervision. This ensures regulatory compliance, accountability, and workmanship consistency across every stage of installation.

Final inspections focus on seam integrity, fixing security, drainage efficiency, and detailing accuracy
Concealed fixing systems hide fasteners beneath the roofing panels rather than exposing them to the weather.
This provides two key benefits:
Concealed fixings also allow controlled thermal movement of the metal, which is critical for long-term performance in standing seam and Euro-style roofing systems.
Yes. A specialist metal roofer can work alongside architects, designers, and builders during the design and specification stage.
This collaboration helps ensure that roofing systems are:
Specialist input at the design stage reduces construction risk and improves long-term performance.
Specialist metal roofing involves two separate forms of warranty:
Correct specification and specialist installation are essential for both warranties to remain valid.
Specialist metal roofing demands informed decisions.
If your project involves architectural detailing, coastal exposure, complex junctions, or long-term performance requirements, early engagement with a metal roofing specialist in Auckland is critical. Correct material selection, system specification, and detailing decisions made at the outset directly affect durability, compliance, and whole-of-life performance.
Onyx Roofing works with homeowners, architects, builders, and commercial clients to provide technical clarity before installation begins. This includes reviewing design intent, exposure conditions, and roofing systems to ensure they are appropriate for Auckland’s environment and regulatory requirements.
