Can I Use Mobile Scaffold Towers for Guttering Work on My Home?

Yes, you can use a mobile scaffold tower for guttering work on your home — and in many cases it's a much safer choice than a ladder. However, there are important rules around working at height in New Zealand that every homeowner needs to understand before hiring or buying a tower and climbing up.

Why a Mobile Scaffold Tower Is Often Better Than a Ladder

For guttering work — cleaning, repairing, or replacing spouting — you're typically working at 2 to 4 metres above ground level on a single-storey home, and potentially higher on a two-storey. A mobile scaffold tower gives you a stable, level platform to stand on, freeing both hands for the job. Ladders require constant repositioning and leave you with only one hand free, which significantly increases the risk of a fall.

WorkSafe NZ identifies falls from height as one of the leading causes of serious injury and death in New Zealand. Even a fall from 2 metres can be fatal or cause life-changing injuries.

Understanding NZ Height Safety Rules for Homeowners

Under the Health and Safety at Work Act 2015 (HSWA), the rules around working at height apply primarily to workplaces and workers — but as a homeowner doing your own DIY, you still have a duty of care to yourself and others on your property.

Key points to be aware of:

• Falls from 1 metre or more are considered a significant risk and require proper controls.
• Falls from 3 metres or more require more robust fall prevention measures — at this height, a properly erected scaffold with guardrails is strongly recommended.
• If you hire a contractor to do the work, they are legally required to manage fall risks under the HSWA and relevant regulations.

For guidance on managing fall risks, WorkSafe NZ publishes practical guidance on working at height that is worth reading before you start.

Choosing the Right Mobile Scaffold Tower

Not all mobile scaffold towers are equal. Here's what to look for:

• Height rating: Check the manufacturer's maximum working height. Most aluminium DIY towers are rated to around 3–5 metres working platform height.
• Guardrails and toe boards: A compliant tower should have guardrails on all open sides (typically at 900 mm and 500 mm height) and toe boards to prevent tools falling.
• Outriggers/stabilisers: For taller configurations, outriggers are essential to prevent tipping.
• Castors with brakes: All wheels must be locked before you climb the tower — every single time.
• NZS/AS compliance: Look for towers that meet AS/NZS 1576 (scaffolding standards) or equivalent. Check with the hire company or retailer.

You can hire mobile scaffold towers from most tool hire outlets, or purchase them from stores like Bunnings or Mitre 10. Hiring is often the most practical option for a one-off guttering job.

Setting Up Your Mobile Scaffold Tower Safely

Follow these steps every time:

1. Read the manufacturer's instructions — assembly order matters.
2. Set up on firm, level ground. Avoid soft soil, slopes, or uneven surfaces without proper base plates or adjustable legs.
3. Lock all castors before stepping onto the platform.
4. Use the internal ladder or climbing frames to access the platform — never climb the outside of the frame.
5. Keep the platform clear of unnecessary tools and materials.
6. Never move the tower while someone is on it.
7. Maintain a 3-metre clearance from overhead power lines — this is a legal requirement. If lines are closer, contact your lines company before starting work.
8. Work within the platform area — don't lean out beyond the guardrails.

What About Two-Storey Homes?

For two-storey homes, guttering work typically puts you at 5 to 7 metres above ground level. At this height, a mobile tower may not be the safest or most practical solution. You may need:

• A fixed scaffold system erected by a licensed scaffolder
• A boom lift or scissor lift hired from a specialist
• A licensed scaffolder to assess and recommend the right access solution

At these heights, the risks increase significantly and the consequences of a fall are severe. It's worth getting professional advice.

Building Consent — Do You Need One?

For most routine guttering maintenance and repair, no building consent is required under Schedule 1 of the Building Act 2004. However, if you're making significant changes to your roofline or drainage, check with your local council. For more information on what work requires consent, visit MBIE Building Performance.

When to Call a Professional

Consider hiring a qualified scaffolder or tradesperson if:

• Your home is two storeys or higher
• The ground around your home is uneven, sloped, or soft
• There are overhead power lines nearby
• You're not confident assembling or working on a scaffold tower
• The guttering work is extensive and will take more than a day
• You have any health conditions that affect your balance or mobility

A licensed scaffolder will erect a safe, compliant scaffold and can often leave it in place for the duration of your project. You can find qualified local scaffolders on tradedirectory.co.nz.

For larger or more complex projects, Licensed Building Practitioners can also advise on the right approach for your specific home.
