In New Zealand, scaffolders can and often do communicate directly with painters, roofers, and other trades — but whether this happens smoothly depends largely on how your project is set up and who is taking the lead. On smaller residential jobs, it's common for trades to sort things out between themselves, while on larger projects a main contractor or project manager usually handles coordination.
How Trade Coordination Typically Works
On most residential projects, there are two common scenarios:
- You're managing the project yourself (owner-builder style): You book each trade separately and are responsible for making sure they talk to each other and sequence their work correctly.
- A main contractor or project manager is involved: They take responsibility for scheduling and coordinating all trades, including the scaffolder, painter, and roofer.
If you're acting as your own project manager, don't assume your scaffolder and painter will automatically get in touch with each other. You'll need to introduce them — even a quick group text or email can prevent costly delays.
Why Coordination Between Scaffolders and Other Trades Matters
Timing is everything when scaffold is involved. Scaffold hire is typically charged by the week, so delays caused by poor coordination can add up quickly. Key things that need to be aligned include:
- Scaffold erection timing: The scaffold needs to be up before the roofer or painter starts, but not so early that you're paying for idle hire time.
- Access and clearances: Painters need the scaffold boards and handrails positioned correctly for their work; roofers may need different configurations for ridge or gutter access.
- Scaffold modifications: If the painter finishes one side of the house before the roofer is done, the scaffold may need to be moved or altered — this must only be done by the scaffolding company, not by other trades.
- Scaffold strike (removal): The scaffold can't come down until all trades using it have finished. Someone needs to confirm this sign-off.
Who Is Responsible for Scaffold Safety?
This is an important point that homeowners often overlook. Under WorkSafe NZ guidelines, the person conducting a business or undertaking (PCBU) — which can include a homeowner managing their own project — has health and safety duties. Scaffold must be erected, altered, and dismantled by competent scaffolders, and a handover certificate should be provided before other trades use it.
Other trades (painters, roofers) must not modify the scaffold in any way — no removing planks, shifting standards, or adjusting handrails. If a painter needs a board repositioned, they must contact the scaffolding company to do it safely and legally.
For scaffolding above certain heights, there are additional requirements under the Health and Safety at Work Act 2015 and associated regulations — check with your scaffolding contractor about the specific thresholds that apply. Always check with your scaffolding contractor about what documentation and inspections apply to your job.
Tips for Smooth Coordination as a Homeowner
If you're managing the trades yourself, here are some practical steps:
- Book your scaffolder first — they set the framework (literally) for everyone else.
- Share contact details between your scaffolder, painter, and roofer so they can communicate directly about access needs.
- Confirm the scaffold spec with each trade before erection — ask your painter and roofer what they need in terms of board height, outriggers, and access points.
- Agree on a sign-off process — decide in advance who confirms when all trades are finished so the scaffold can be struck promptly.
- Get the handover certificate from your scaffolder before other trades go up.
- Factor in weather delays — New Zealand weather, particularly in coastal or high-wind areas, can push timelines out. Build some buffer into your schedule.
Scaffold and Building Consent
Most temporary scaffolding for maintenance work (painting, re-roofing) does not require a building consent under Schedule 1 of the Building Act 2004 — but this can depend on the specifics of your project. For example, if your re-roofing job involves structural changes, consent may be required for the roofing work itself. Always confirm with your local council what consents apply to your project. MBIE Building Performance has useful guidance on when consents are needed.
For roofing work specifically, BRANZ publishes technical guidance on best practice that your roofer should be following, which can also affect how scaffold needs to be set up.
When to Call a Professional
If your project involves multiple trades and a tight timeline, consider engaging a licensed building practitioner (LBP) or experienced project manager to coordinate everything. This is especially worthwhile for:
- Full re-roofing jobs combined with exterior repaints
- Multi-storey homes where scaffold complexity is higher
- Projects where you're not confident managing trade sequencing yourself
You can find qualified local scaffolders, painters, roofers, and project managers on tradedirectory.co.nz. Checking that your tradespeople are appropriately licensed — for example, LBPs for restricted building work via Licensed Building Practitioners — gives you added peace of mind.
