Most building managers only think about roof access when a contractor asks, “Are your anchors in date?” By then a job is booked and a lapsed certificate or a missing roof hatch can delay it by weeks. This guide explains the main parts of a roof height safety system, what each one does, and what to check before your next painting, window cleaning or façade job.
The parts of a roof height safety system
Roof access hatches
A roof access hatch is often the only way onto the roof for contractors and maintenance staff. A hatch that is hard to open, has no safe ladder below it or leaves an unprotected opening once open is a hazard in itself. Roof hatches, ladders and walkways are covered by AS 1657 (fixed platforms, walkways, stairways and ladders). When we install or replace a hatch, we look at how people climb through it, how it is held open and how the opening is protected while someone is on the roof.
Anchor points
Anchor points are fixed attachment points on the roof or structure. Rope access technicians rig from them to paint, clean windows or repair façades, and workers on the roof clip on to them for fall arrest. Single-point anchors are covered by AS/NZS 5532, and their selection, use and inspection by AS/NZS 1891.4.
Static lines
A static line is a horizontal lifeline fixed along the roof. It lets a worker stay connected while moving along a roof edge, rather than unclipping and reclipping between single anchors. On long roofs, or where workers need to move along an edge often, a static line can be more practical than a row of single anchors. Many roofs use both.
Guardrails
Guardrails are collective edge protection: they protect everyone on the roof without anyone needing to clip on. Where a roof is accessed regularly (plant rooms, air conditioning units, solar panels), guardrails along the edge or around the work area are often the better long-term option.
Inspection and certification
Anchor points and static lines need periodic inspection by a competent person, generally at intervals of no more than 12 months under AS/NZS 1891.4. Each anchor is checked, tagged and recorded. Anything that fails is tagged out of service until it is repaired or replaced.
A good inspection leaves you with a report you can file: anchor locations on a roof plan, the result for each point, photos of any defects and the next due date. Strata committees and insurers often ask for exactly this.
What to check before your next maintenance job
- Is there a safe way onto the roof, through a hatch or door, with a fixed ladder or stairs?
- Are all anchor points and static lines tagged and inside their inspection date?
- Is there a current roof plan showing where the anchors are?
- Are roof edges near plant or regular access points protected by guardrails?
- Do the anchors reach every drop the contractor needs for the façade or windows?
If the answer to any of these is no, sort it out before booking the work. It is much cheaper to fix roof access once than to pay for delays on every job that follows.
One contractor for access and the work itself
Ace Abseiling installs, inspects and certifies anchor points, static lines, guardrails and roof access hatches across Sydney. Because our team also carries out high-rise window cleaning and rope access painting, we can certify the anchors and complete the maintenance in the same visit.
