Scaffolding Edge Protection for Roofers — Complete NZ Guide (2026)

If you're a roofer in New Zealand, edge protection is not optional. WorkSafe NZ's regulations under the Health and Safety at Work (General Risk and Workplace Management) Regulations 2016 require that any work at height — including roof work — must be done with fall protection in place before the job starts. For most reroofing and roofing repairs in New Zealand, that means scaffolding edge protection.

This guide covers exactly what scaffolding edge protection for roofers involves, when you need full scaffolding versus edge protection only, what it costs in 2026, and how to set it up correctly so your roofer can start work and you can avoid a WorkSafe improvement notice.

What Is Scaffolding Edge Protection for Roofers?

Scaffolding edge protection is a perimeter barrier system erected around the roof line of a building before any roofing work begins. It is designed to prevent roofers (and any materials or tools) from falling off the edge of the roof during work.

A compliant scaffolding edge protection system for roofers typically includes:

• Top guardrail — at least 900mm above the working surface
• Mid-rail — at the halfway point between the guardrail and the working deck
• Toe board — a solid board at deck level to prevent tools and materials rolling off the edge
• Scaffolding boards — a stable working platform at eave level for the roofer to stand on and place materials
• Uprights and ledgers — the structural scaffolding tube that supports the whole system

On a standard single-storey house in Wellington or the Hutt Valley, this typically means a single-lift scaffolding system running along the eaves with guardrail above. On a two-storey home, a two-lift system is usually required.

When Does WorkSafe NZ Require Edge Protection for Roofers?

Under the Health and Safety at Work Act 2015 and the associated regulations, any person working at height of 1.5 metres or more must have fall protection in place. For roofing work, this almost always means scaffolding edge protection.

There are a few scenarios where alternative fall protection might be accepted — for example, a safety harness and inertia reel lanyard — but in practice, these are rarely appropriate for the kind of sustained work a roofer is doing. Roofers moving constantly across a pitched roof, carrying materials, cutting iron sheets, and working at the ridge cannot practically be harnessed and anchored at all times. Scaffolding edge protection is the standard solution because it provides passive fall protection without requiring the roofer to manage their own restraint system.

Key situations requiring scaffolding edge protection for roofers in NZ:

• Reroofing — full roof replacement, stripping and re-laying iron or tiles. Full perimeter edge protection is required.
• Partial reroofing — replacing sections of roof. Edge protection to the sections being worked is required.
• Ridge capping and flashing — work at or near the ridge requires protection at the eave level.
• Gutter and fascia replacement — working at the eave edge specifically, edge protection is essential.
• Solar panel installation — panels are typically installed by roofers; edge protection is required.
• Roof inspection — if the inspector is walking on the roof, edge protection is required.

The test is simple: if a roofer is on the roof, edge protection must be in place before they get up there. This is the principal's responsibility as well as the roofer's. As a homeowner or building owner, you have a duty to ensure the work environment is safe — which in practice means making sure scaffolding edge protection is erected before the roofer arrives.

Types of Scaffolding Edge Protection for Roofers

1. Perimeter eave scaffolding with guardrail (most common)

The most common form of scaffolding edge protection for roofers is a single or double-lift scaffolding along the eaves of the building, with a guardrail system above. The roofer can stand on the scaffolding boards at eave level to load materials, nail off the last run of iron, and access the guttering. The guardrail prevents any fall over the edge.

This is the standard setup for a residential reroof in New Zealand and what most scaffolding companies (including Erect It) will quote as standard edge protection for reroofing.

2. Catchfall scaffolding

A catchfall is a scaffolding structure that sits below the eave at an angle, acting as a net to catch a roofer or materials if they slide down the roof. Catchfalls are used in addition to perimeter scaffolding on very steep-pitched roofs where the primary risk is a roofer sliding off the slope rather than stepping off the edge. Common on older 45-degree-pitch homes in Wellington's character suburbs.

3. Roof safety nets

Safety nets are installed below the roof plane to catch anyone who falls through the roof or slides from the ridge. They are more common on new builds with open framing than on reroofing jobs where the existing deck provides some structure. They complement but do not replace perimeter edge protection.

4. Temporary roof and full encapsulation

For large-scale reroofing in exposed locations — particularly in Wellington's windy conditions — a full scaffolding shrinkwrap and temporary roof may be erected. This provides both fall protection and weather protection, allowing the existing roof to be fully stripped without exposing the interior. More expensive than standard edge protection, but the only viable option for significant Wellington reroofing in winter.

Full Scaffolding vs Edge Protection Only — What's the Difference?

Roofers and homeowners often ask whether they need full scaffolding or whether edge protection alone is sufficient.

Edge protection refers specifically to the perimeter guardrail system at the roof edge. It protects against falling off the edge of the roof.

Full scaffolding provides working platforms at multiple heights, giving painters, builders, and other trades access to the full exterior of the building — walls, eaves, and fascias — not just the roof edge.

For reroofing only, edge protection is usually sufficient. The roofer needs protection at the eave edge — they don't need platforms along the walls.

For combination projects — where you're reroofing and painting at the same time, or reroofing and replacing the fascia boards — full scaffolding is more economical because it provides access for both trades simultaneously.

If you're in any doubt, call the scaffolding company and describe the scope of work — they will tell you what WorkSafe NZ requires and quote accordingly.

How to Arrange Scaffolding Edge Protection for a Reroofing Job

Getting scaffolding edge protection in place for a reroofing job is straightforward, but timing matters. Here's the right sequence:

1. Book the scaffolding before the roofer arrives.

The scaffolding must be erected and the handover certificate provided to the roofer before they start. Roofers cannot legally start work on a roof without compliant edge protection in place. Book your scaffolding at least a week ahead of the roofer's start date — ideally as soon as you have a roofer confirmed.

2. Confirm the roofer's programme with the scaffolding company.

Tell us when the roofer is starting and how long the job is expected to take. We'll erect the day before they start and dismantle within 24–48 hours of them finishing. Shorter hire = lower hire cost for you.

3. Receive the handover certificate.

The scaffolding company provides a handover certificate confirming the scaffolding is WorkSafe NZ compliant and safe to use. The roofer should sight this before starting work. Keep a copy for your site file.

4. Don't dismantle early.

It's tempting to call the scaffolding off as soon as the main roofing is done to save hire cost. But if the roofer still needs to return for ridge capping, flashing, or sign-off inspection, the edge protection must still be in place. Confirm with the roofer that all roof work is completely finished before booking the dismantle.

Who Is Responsible for Edge Protection — the Roofer or the Homeowner?

This is one of the most common questions homeowners ask. Under New Zealand health and safety law, both the person doing the work (the roofer) and the person managing or controlling the workplace (the homeowner or building owner) have duties.

In practice:

• The roofer must not start work without compliant edge protection in place.
• The homeowner has a duty to ensure the work environment is safe — which means arranging and paying for the scaffolding edge protection before the roofer starts.
• A principal contractor (if there is one on a commercial site) is responsible for ensuring all subcontractors have safe access.

Most residential roofers in Wellington and the Hutt Valley will not start a reroofing job without confirmed scaffolding edge protection. If a roofer turns up and there's no scaffolding, they will typically not start work — and they are correct not to. The homeowner is responsible for having it ready.

Coordinating Your Roofer and Scaffolding Company

The best results come from putting the scaffolding company and the roofer in contact with each other directly. At Erect It, owner Dhillon coordinates timing directly with your roofer — confirming the start date, the expected duration, and booking the dismantle as soon as the roofer finishes. This minimises hire days and reduces the total cost for the homeowner.

If your roofer has a preferred scaffolding company they work with regularly, that's a good sign — it usually means the coordination is smooth and the scaffolding will be up exactly when it needs to be. If not, call Erect It on 027 886 6688 and provide the roofer's contact details. We'll sort the rest.
