WAH — General Roof Access SWMS
General roof access for inspection, maintenance, and minor works including anchor point use and edge protection.
SWMS variants reference your state's WHS legislation. Instant download after payment.
This SWMS covers general roof access for inspection, maintenance, non-disruptive minor works, condition survey, and short-duration trade tasks where the primary purpose of the roof visit is access rather than sustained construction. It is written for facility managers, building surveyors, HVAC technicians conducting rooftop plant inspections, roof inspectors preparing dilapidation reports, and any trade crew whose task involves setting foot on the roof plane for a discrete period. The work is distinct from roof plumbing or roof sheeting because the worker typically spends less than a shift on the roof, moves across the full roof plane rather than dwelling at the eave, and interacts with existing roof safety infrastructure (permanent anchors, walkways, catwalks, and skylight demarcation) rather than installing their own. The dominant decision point in roof-access work is whether the existing safety infrastructure can be relied on — and if not, what alternative control is put in place before access commences. All work above 2 m is HRCW Category 3 under Schedule 1 of the WHS Regulation 2025; Section 299 requires this SWMS. The document is CIH-authored against the current WHS Regulation 2025 baseline and aligns with AS/NZS 1657 for fixed platforms, walkways, and ladders.
Hazards identified
10 hazards covered, sorted by priority.
Fall-arrest anchor fails during a fall event because annual certification to AS/NZS 1891.4 has lapsed; worker falls to ground.
Skylight mistaken for roof sheet by an inspector unfamiliar with the roof plan; fall-through to floor below.
Loss of traction on UV-degraded walkway insert or algae-covered crawl board; slip to edge of walkway.
Inspector steps off a demarcated walkway to access a plant item, entering the fragile-material zone; subsequent fall-through event.
Rain, frost, or dew developing during the access window; slip to edge because the pre-entry weather assessment did not include the forecast window.
Incapacitation from fall, medical event, or heat stroke with no second person to call for assistance; delayed rescue beyond the suspension-trauma window.
Contact injury from unguarded condenser fan, steam vent, or cooking-exhaust rooftop unit running during the inspection.
Fall during the transition from ladder to roof plane because the ladder is not tied at the top; slip at the upper landing.
Shoulder and back strain from carrying thermography camera, drone kit, moisture meter, or anemometer up a ladder or through a tight roof-hatch.
Electrocution from contact with solar DC cabling in the roof cavity or across the roof plane; DC circuit cannot be de-energised by daylight isolation alone.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Before roof access, obtain the building's roof safety register and the current anchor-point certification record — no access unless certification is within 12 months per AS/NZS 1891.4; walkways and guardrails have current compliance certification to AS/NZS 1657.
- 2Where the certification is absent or lapsed, the access does not proceed on the building's safety infrastructure; the SWMS requires substitution of a temporary control (scaffold, mobile EWP, or temporary horizontal life line installed by a competent person).
- 3Review the roof safety plan and plant drawing before access — map skylights, fragile sheeting, walkway routes, fall arrest anchors, and rooftop plant. Staple a copy to the SWMS before the site visit.
- 4Designated walkway use is mandatory — the inspector follows the walkway route continuously. Any off-walkway access requires an amended SWMS entry identifying the alternative control (e.g. additional anchor, fall-through cover).
- 5Weather window check within 2 hours of access — rainfall, wind above 40 km/h sustained, and ambient below 5°C or above 35°C invoke a hold; the forecast must cover the planned duration plus one hour contingency.
- 6Lone-working is not permitted — minimum two-person access with radio contact, or a ground-based safety observer with a rescue plan and the trained rescuer named on the SWMS; suspension-trauma onset is 5-30 minutes per AS/NZS 1891.4 commentary, the rescue capability must meet this window.
- 7Fall-arrest harness per AS/NZS 1891.1 donned and inspected before access — pre-use check of webbing, buckles, lanyard shock absorber condition, and snap-hook gates per the AS/NZS 1891.4 user check.
- 8Roof ladder or fixed-access ladder tied at the upper landing, extending 900 mm above the landing per AS/NZS 1892; no ladder is ascended while un-tied at the upper landing beyond three rungs.
- 9Rooftop plant isolation before contact — any condenser, fan, or vent within 2 m of the inspector's route is electrically isolated or the inspector confirms running status and maintains clearance. Lock-out tag-out per the Code of Practice: Managing Electrical Risks in the Workplace (SafeWork Australia, 2020).
- 10Solar PV isolation — DC roof-top isolator opened per AS/NZS 5033 before any contact with PV cabling; assume DC voltage present in daylight regardless of isolation until voltage tested.
- 11PPE baseline: cut-5 gloves (AS/NZS 2161.3), Grade II eyewear (AS/NZS 1337.1), grip-rated safety footwear suitable for the roof surface (AS/NZS 2210.3), high-visibility long-sleeve shirt, hard hat with chin strap (AS/NZS 1801).
- 12Lightweight inspection equipment is hoisted in a bucket rather than carried up a ladder; tools are tethered to the harness or to an anchored tool lanyard during roof movement to prevent drop events.
- 13All roof-access workers hold a valid White Card (CPCCWHS1001); height-safety refresher training completed within the last 24 months per the PCBU training register.
- 14Pre-entry SWMS acknowledgement by all access personnel including the rescue observer; record on the worker sign-on register with time-in, time-out, and task-description fields.
Applicable Codes of Practice
Primary binding guidance for the fall-protection hierarchy applied to general roof-access work.
Establishes SWMS preparation duty where roof access is construction-related inspection or minor works.
Applies to isolation of rooftop plant and solar PV during access.
Governs rooftop HVAC plant interaction during inspection.
Compliance standard for the building's permanent roof walkway and guardrail infrastructure relied on during access.
Design, use, and anchor certification standard for harness-based controls on roof access.
Governs DC isolation of rooftop solar arrays before roof contact.
High-Risk Construction Work triggered
All roof access above 2 m eave height is Category 3 regardless of task duration; the Regulation does not provide a short-duration or inspection-only exemption from HRCW.
Because general roof access triggers HRCW Category 3, Section 299 of the WHS Regulation 2025 requires the SWMS to be prepared before access and provided to the property owner or Principal Contractor on request. Section 300 maximum penalty for failure to prepare or maintain a current SWMS is $36,000 for a body corporate and $7,200 for an individual. Where an inspector or surveyor falls because the PCBU did not verify existing anchor-point certification, Category 2 prosecution under Section 32 of the WHS Act 2011 is foreseeable — up to $1.73 million for a body corporate and $346,000 for an individual.

Worked example
A building surveyor and a safety observer are engaged to conduct a dilapidation inspection on a 1998-built Class 5 office roof in Chatswood before a tenant fitout. Eave height is 8.2 m. Before access the surveyor completes this SWMS and obtains the building's roof-safety register — the six permanent anchors have current AS/NZS 1891.4 certification, the walkway has a current AS/NZS 1657 compliance label, and the three skylights are covered with compliant guards. The surveyor and observer ascend via the internal roof hatch, clip to the anchor at the hatch, and follow the demarcated walkway. A thermography camera is hoisted in a bucket rather than carried up. Total time on roof is 90 minutes; the SWMS closes with time-out at 11:15 and a signed observation that one skylight guard has a loose fixing — reported to the building manager for rectification before the next access.

Frequently asked questions
Is a SWMS required for a 20-minute roof inspection?
Yes. The WHS Regulation 2025 does not include a minimum-duration exemption from HRCW SWMS requirements. If the inspection is above 2 m, a SWMS must be prepared before access. The format may be brief, but the HRCW content under Section 299 is required regardless of task length.
Can the building's existing harness be used by the inspector?
Only if the building's harness has a current AS/NZS 1891.4 inspection tag and the inspector has been sized to fit it. In practice, inspectors bring their own harness, which is the default control in this SWMS. Shared harnesses without size verification are not acceptable.
What qualifies as a current anchor-point certification?
An anchor is current when inspected by a competent person within the last 12 months and tagged accordingly. The certification record should state the anchor identification, inspection date, inspector name, and pass/fail outcome. Anchors without a visible tag or register entry are treated as failed and do not support access.
Is a standalone ladder access acceptable for a maintenance visit?
Only for tasks that do not require foot placement onto the roof plane. Once the worker steps off the ladder and onto the roof, the ladder ceases to be the fall-protection control and the hierarchy returns to edge-protection, restraint, or arrest as described in the SWMS. Many short-duration tasks are better performed from a mobile EWP than from a roof ladder.
Does this SWMS cover drone-assisted inspection from the ground?
No. Where inspection is conducted fully from ground level with a drone or pole camera, there is no fall exposure and no HRCW SWMS is required. This SWMS specifically covers human access to the roof plane; drone operation has its own CASA RPAS regulatory regime.
