Every building that requires periodic roof maintenance — for gutter cleaning, antenna servicing, mechanical plant access, or inspection — needs a compliant, safe way to get people up there. Without properly engineered roof safety systems, routine maintenance becomes a WorkSafe liability, and insurers have legitimate grounds to deny claims for incidents that occur during unprotected access.

Atomic Projects designs, supplies, and installs NCC and AS/NZS 1891-compliant roof access and fall prevention systems for residential, commercial, and strata buildings across Sydney. We also certify existing systems and recommend upgrades where current installations no longer meet modern standards.

Our Approach to Roof Safety & Access Systems

1. Access Requirements Assessment — We review how the roof is accessed and used: the frequency of maintenance, the trades involved, roof pitch and surface type, and existing access infrastructure. This informs the system type required.
2. System Design — Engineered anchor layouts and walkway configurations are designed in accordance with AS/NZS 1891 (Industrial Fall Arrest Systems) and AS 1657 (Fixed Platforms, Walkways, Stairways and Ladders). For complex roofs, a specialist engineer provides a compliance certificate with the design.
3. Anchor Point Installation — Static anchor points, horizontal lifelines, and traveller systems are installed with engineered fixings into the roof structure — not just into sheeting or tiles. Each anchor is rated and tested to the required load.
4. Walkways & Edge Protection — Aluminium or fibreglass walkways protect both the roof membrane and the worker. Modular edge protection systems or permanent guardrails are installed at leading edges, skylights, and openings.
5. Roof Access Hatches & Fixed Ladders — Where ladder access from internal ceiling spaces is required, we supply and install compliant roof access hatches, fixed vertical ladders, and cage ladders for safe egress and ingress.
6. Certification & Handover — All completed systems are independently certified by a structural engineer. A compliance register with installation details, load ratings, and inspection intervals is provided to the building manager or strata committee.

Frequently Asked Questions

What types of buildings need roof safety systems?

Any building where workers regularly access the roof requires a compliant fall arrest or fall prevention system under the Work Health and Safety Act 2011. This includes apartment buildings (for gutter, antenna, and HVAC maintenance), commercial properties, and any building with rooftop plant equipment. The threshold for a compliant system is any roof access work involving a risk of a fall greater than 2 metres.

How often should roof anchor points be inspected?

Under AS/NZS 1891, anchor points and lifeline systems must be inspected annually by a competent person. We offer annual inspection and re-certification services to keep buildings compliant and maintain the system's warranty.

Can existing anchor points be re-certified if they're already installed?

Yes. We assess existing anchors, test fixings to required load capacities, and issue a compliance certificate if they meet current standards. Where anchors fail the inspection, we replace or supplement them to achieve full compliance.

Who is responsible for ensuring roof access systems are compliant — the strata manager or the owners corporation?

The owners corporation holds the duty of care as the building's property owner and employer of contractors. Strata managers facilitate compliance, but the legal obligation sits with the OC. Non-compliant or absent roof access systems can expose the OC to significant liability under WHS legislation.

Does installing roof safety systems require council approval?

Anchor points and walkways are typically classified as exempt development in NSW. However, if the building is heritage-listed or the works involve structural changes, a development application or heritage consultation may be required. We advise on this during the scoping stage.
