Slate roof installation and repair on heritage and contemporary structures combines several of the highest-risk construction activities recognised under Australian WHS law. Workers handle natural slate tiles weighing 1.5 to 4 kilograms each at pitches typically exceeding 30 degrees, install copper or zinc flashings around penetrations, and frequently work above brittle substrates including aged sarking, deteriorated battens, and original lath. Because the activity involves work at heights above two metres, manual handling of heavy roofing materials, and exposure to fragile or weathered roof surfaces, it meets multiple High Risk Construction Work triggers under WHS Regulation 2025 r291 (formerly 2011 r291) and the harmonised state regulations. A documented Safe Work Method Statement is mandatory before work commences, must be developed in consultation with affected workers, must be available at the workplace for the duration of the task, and must be reviewed whenever controls fail or conditions change. This template captures the trade-specific hazards, hierarchy-of-control responses, and supervisor sign-on requirements needed to discharge the PCBU duty.
Hazards identified
7 hazards covered, sorted by priority.
Fatal or catastrophic multi-trauma injuries from falls exceeding two metres onto hard landscaping or scaffold below
Penetration fall into roof void causing impalement, spinal fracture, or fatal internal injuries on heritage buildings
Acute lumbar disc injury, rotator cuff tears, and chronic musculoskeletal disorders from repetitive heavy lifting
Skull fracture or fatal head injury to ground workers, public, or occupants from objects falling from height
Accelerated silicosis, lead toxicity with neurological impairment, and notifiable occupational disease under WHS Regulations
Heat stroke, dehydration collapse leading to secondary fall injury, and cumulative skin cancer risk
Loss of footing on smooth wet slate, dropped materials, and uncontrolled descent down roof plane
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Schedule pre-fabrication of valley, ridge, and flashing assemblies at ground level so installers minimise time spent cutting and fitting at height.
- 2Elimination — Cancel and reschedule work when wind speed exceeds 36 km/h, during rain, or when slate surface moisture creates slip conditions per SafeWork heights guidance.
- 3Substitution — Use mechanically fixed slate hooks or copper rivets instead of nailed fixing where heritage approval permits, reducing repeated hammering postures at the roof edge.
- 4Substitution — Replace petrol angle grinders with low-vibration electric slate cutters fitted with on-tool water suppression to control respirable crystalline silica.
- 5Engineering — Install compliant perimeter edge protection to AS/NZS 4994.1 with mid-rail, toeboard, and 900mm top rail before any worker accesses the roof plane.
- 6Engineering — Lay temporary fragile-surface crawl boards and load-rated roof ladders across battens to spread point loads and prevent penetration through aged substrate.
- 7Administrative — Conduct documented pre-start toolbox using this SWMS, verify each worker holds Working at Heights training, and complete sign-on register before access.
- 8Administrative — Implement exclusion zone with hard barricade and spotter below roof edge; rotate workers every 90 minutes during heat to manage thermal load.
- 9PPE — Issue full body harness to AS/NZS 1891.1 with twin lanyards anchored to certified roof anchors installed per AS/NZS 5532, inspected before each shift.
- 10PPE — Provide P2 respirators for slate cutting tasks, cut-resistant gloves, non-slip soft-sole roofing boots, hard hats with chin straps, and long-sleeve UPF50+ clothing.
Applicable Codes of Practice
Sets the mandatory hierarchy for fall prevention, fall arrest anchor design, and edge protection that applies to all pitched roof slating work above two metres.
Specifies harness construction, inspection intervals, and connector ratings required for the fall-arrest PPE used by slaters when collective controls are not reasonably practicable.
Defines load ratings, top rail heights, and toeboard requirements for the perimeter scaffold edge protection installed before slate roof access.
Confirms slate roofing meets High Risk Construction Work definitions and mandates the SWMS preparation, consultation, and on-site availability obligations.
High-Risk Construction Work triggered
Slate repair routinely exposes workers to aged sarking, weathered timber lath, and deteriorated batten systems that cannot reliably support a person's weight.
Slate roof pitches and eave heights on residential and heritage buildings consistently exceed the two-metre fall threshold across the entire work area.
Material delivery, telehandler slate lifting, and elevated work platforms operate within the loading and access zone throughout slating works.
PCBU must prepare, consult workers on, and retain this SWMS for the project duration plus two years if a notifiable incident occurs; penalties are substantial and indexed annually under the prevailing WHS schedule.

Worked example
On a heritage two-storey residence with a 38-degree natural slate roof, the lead slater arrives at 6:45 am and gathers the three-person crew at the loading bay for the pre-start brief. They open this SWMS on a tablet and walk through each hazard line by line. The crew confirms perimeter scaffold with mid-rail edge protection was certified the previous afternoon and notes two existing certified roof anchors plus the need for temporary crawl boards over a section of suspected rotten lath near the western valley. The supervisor checks the Bureau of Meteorology forecast — winds gusting to 28 km/h, below the 36 km/h cancellation threshold — and confirms a heat management rotation given a forecast 34-degree maximum. Each worker signs the SWMS sign-on register, with the new apprentice initialling the fragile-surface control specifically. At 11:20 am the crew discovers the valley batten is more degraded than expected; work stops, the supervisor amends the SWMS with an additional crawl board control, re-briefs the team, and obtains fresh signatures before resuming. The amended document is photographed and uploaded to the project file. At smoko the supervisor notes humidity is climbing and shortens the rotation cycle from 90 to 60 minutes, recording the change in the daily diary attached to the SWMS.
