WAH — Roof Plumbing SWMS
Roof plumbing including gutters, downpipes, flashings, and rainwater systems on pitched and flat roofs.
SWMS variants reference your state's WHS legislation. Instant download after payment.
This SWMS covers licensed roof-plumbing work on Australian construction and maintenance sites — gutter and downpipe installation, box-gutter and valley fabrication, flashings around penetrations, rainwater head and sump detailing, overflow devices, and the set-out and jointing of rainwater tanks back to the roof catchment. It is written for roof plumbers, plumbing apprentices working under direct supervision, and contracting PCBUs engaged on Class 1 through Class 9 building work. The document targets pitched and low-pitch roofs where edge-of-roof detailing forces the worker within 600 mm of an unprotected edge for sustained periods — exactly the scenario the Code of Practice: Managing the Risk of Falls at Workplaces (SafeWork Australia, 2011) identifies as the dominant roof-plumbing fatality mode. Under Schedule 1 of the WHS Regulation 2025, all work involving a risk of a person falling more than 2 metres is Category 3 high-risk construction work. Under Section 299 of the Regulation a SWMS must be prepared and made available to the Principal Contractor on request. This document is CIH-authored against the current regulatory baseline and aligns with AS/NZS 3500.3 for stormwater drainage.
Hazards identified
11 hazards covered, sorted by priority.
Fatal or permanent spinal injury from falls onto driveways, paved courtyards, or unyielding ground below eave level; most roof-plumbing fatalities in Australia occur at the eave line during bracket set-out.
Fall through brittle material without warning; fatal internal injury even from short drops where the worker strikes trusses or concrete slab below.
Foot penetration through corroded gutter floor into the roof cavity; laceration, fall through ceiling, or secondary fall from height.
Deep hand and forearm lacerations; tendon damage from burr contact during carrying and dressing of fabricated flashings.
Worker pulled off edge by gust catching a 3 m flashing or gutter length; loss of balance even at moderate wind speeds above 35 km/h.
Electrocution or severe arc-flash burn when 6 m downpipe or gutter length is raised near service drop or LV aerial.
Blood-lead elevation from cutting, brushing, or oxy-burning aged lead flashings; respiratory exposure during hot dress.
Dermatitis, sensitisation, and upper-airway irritation from MS polymer, neutral-cure silicone, and solvent cleaners used on flashings.
Acute lumbar strain and chronic shoulder injury from single-worker carry up ladders and across pitched surfaces.
Ladder slip or overreach while dressing downpipe brackets at height; injury from 3-5 m drop onto paved ground.
Loss of footing on wet metal or tile near edge; unrestrained slide to eave and fall.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Eliminate the fall risk wherever reasonably practicable by specifying ground-level pre-fabrication of gutters, downpipes, flashings and sumps — deliver the complete run to the roof ready to fix, not fabricate in situ.
- 2Where eave work cannot be eliminated, provide a fixed guardrail edge-protection system compliant with the Code of Practice: Managing the Risk of Falls at Workplaces (SafeWork Australia, 2011) and AS/NZS 4994.1 before any worker accesses the roof plane.
- 3If edge protection is not reasonably practicable for brief tasks on low-pitch (<10°) roofs above 2 m, use a travel-restraint system anchored to an AS/NZS 1891.4-certified anchor point with a lanyard length that physically prevents the worker reaching an unprotected edge.
- 4Fall-arrest harness per AS/NZS 1891.1 (full body harness, shock-absorbing lanyard, rated anchor) is the minimum control only where higher-order controls have been demonstrated not reasonably practicable — anchor points certified annually per AS/NZS 1891.4 with a documented rescue plan and trained rescuer on site.
- 5Before roof access, conduct a fragility assessment: all skylights, polycarbonate sheets, and pre-2004 fibre-cement sheet roofs are treated as fragile until demonstrated otherwise. Install fall-through covers or guarded demarcation per AS/NZS 5532.
- 6Box-gutter work requires a pre-entry integrity check — probe the gutter floor with a blunt tool at 500 mm centres, inspect from underside where safe access exists, and lay roof ladders or crawl boards rated to AS/NZS 1892 along the gutter length.
- 7Exclusion zones for overhead power lines per the Code of Practice: Excavation Work (for underground) and the SafeWork NSW Overhead Power Lines guideline — 3 m minimum clearance from LV lines, 6.4 m from transmission; de-energise via Ausgrid / Endeavour / Essential Energy where lines cannot be cleared.
- 8Wind-speed work limit — suspend handling of lengths greater than 2 m when sustained wind exceeds 35 km/h at the roof height (measured by on-site anemometer or nearest BOM AWS); full stop at 50 km/h per AS 1418.10 wind-limit logic applied to manual handling.
- 9Mechanical aid for long lengths — two-person carry mandatory above 6 m gutter or 25 kg, roof hoist or boom-lift placement for 450 mm box gutter sections, with the Code of Practice: Hazardous Manual Tasks (SafeWork Australia, 2020) risk-assessment tool applied before task.
- 10Lead-flashing controls — wet-cut with snips or nibbler rather than disc; no oxy-burning without a Lead Work Plan, local exhaust, and RPL air-fed respirator meeting AS/NZS 1716. Blood-lead baseline and 3-monthly bio-monitoring per the Code of Practice: Managing Risks of Hazardous Chemicals in the Workplace.
- 11PPE baseline: cut-5 gloves (AS/NZS 2161.3) for sheet handling, medium-impact safety eyewear (AS/NZS 1337.1), safety footwear with grip-rated sole (AS/NZS 2210.3), long-sleeve UV-rated shirt, and a cap or brim under the hard hat per AS/NZS 1801.
- 12All roof plumbers must hold the relevant state roof-plumbing licence and a current White Card (CPCCWHS1001). Apprentices operate under direct visual supervision of a licensed tradesperson throughout roof access.
- 13Daily pre-start inspection of harness, lanyard, snap-hooks, and anchor points per the AS/NZS 1891.4 user check. Remove from service and tag-out any component with visible damage, UV degradation, or fall-event history.
- 14Rescue plan posted on site before any harness-based access commences — identify the rescue platform (EWP, adjacent roof, window access), the trained rescuer, and the maximum suspension time (suspension trauma symptoms onset 5-30 minutes per AS/NZS 1891.4 commentary).
- 15Daily toolbox talk covering the day's scope, weather window, fragility map of the roof, and any change from prior day. Record attendance on the SWMS worker sign-on register.
Applicable Codes of Practice
Primary binding guidance for all fall-protection controls used in this SWMS — hierarchy of control, edge protection specification, and fall-arrest rescue requirements.
Applies where roof-plumbing work is on Class 1a dwellings; sets minimum edge protection for residential roof work.
Establishes the SWMS preparation, HRCW categorisation, and Principal Contractor notification baseline this document satisfies.
Governs risk assessment for gutter and downpipe handling on roofs and ladder ascent.
Applies to roof plumbing on pre-2004 buildings where flashings and soakers may be in contact with fibre-cement sheet.
Technical standard governing gutter sizing, box-gutter design, rainwater head capacity, and overflow provision.
Design, selection, use, maintenance, and anchor certification for harness-based fall protection on roof-plumbing tasks.
High-Risk Construction Work triggered
All roof-plumbing work on a pitched roof, box gutter, or eave line above 2 m presents a fall risk regardless of task duration; the SWMS therefore applies to the entire roof-access period, not only to the fixing activity.
Because this work triggers HRCW Category 3, Section 299 of the WHS Regulation 2025 requires the SWMS to be prepared before work commences, kept available on site for inspection, reviewed if the work changes, and provided to the Principal Contractor on request. Under Section 300, failure by a PCBU to prepare or keep a current SWMS for HRCW carries a maximum penalty of $36,000 for a body corporate and $7,200 for an individual. Where a fall event occurs and no SWMS existed, prosecutors routinely pursue Category 1 and Category 2 offences under Sections 31 and 32 of the WHS Act 2011 — carrying prison terms and corporate penalties to $3.46 million.

Worked example
A two-person roof-plumbing crew — one licensed roof plumber and one third-year apprentice — is subcontracted to install 48 m of 150 mm quad gutter, two rainwater heads, and two 90 mm downpipes on a new pitched metal roof in Kellyville at a two-storey Class 1a dwelling. The eave height is 6.2 m above a paved driveway. Before work commences the roof plumber completes this SWMS: the roof height triggers HRCW Category 3; edge-protection scaffold is erected by a licensed SB scaffolder along the eave; a roof-access ladder is tied; the apprentice does not carry any length above 3 m; the overhead Ausgrid LV service drop is isolated by Ausgrid for the day. On day 2 an unplanned skylight detail emerges; the SWMS is amended to add a fall-through cover, re-acknowledged by both workers, and filed.

Frequently asked questions
Does this SWMS require fall-arrest harness for every roof-plumbing task?
No — the SWMS follows the hierarchy of control. The primary control is eliminate or reduce the fall risk through edge-protection guardrails or pre-fabrication at ground level. Harness-based fall arrest is only used where higher-order controls are not reasonably practicable, and then only with a documented rescue plan. A compliant SWMS should not default to harness as the first control.
Can I use this SWMS in Victoria?
You can use it as a starting point, but Victoria operates under the OHS Act 2004 and OHS Regulations 2017. The legislation schedule at the end of the SWMS should be updated with the OHS-Act equivalents, and the relevant WorkSafe Victoria Compliance Code: Prevention of Falls in General Construction should be cited in place of the SafeWork Australia Code. The hazard controls themselves remain valid.
Does this SWMS cover lead-flashing work?
Yes — hazard 7 and the corresponding control specifically cover lead-flashing dust and fume. Where oxy-burning of lead is planned, the SWMS requires a separate Lead Work Plan, RPL air-fed respirator, and blood-lead bio-monitoring per the Hazardous Chemicals Code of Practice.
What anchor-point certification interval applies?
Permanent roof anchor points must be certified annually by a competent person to AS/NZS 1891.4. The certification tag must be visible at the anchor or recorded in an access register. Temporary anchors installed for a single project must be inspected before first use and before each subsequent shift.
Is this SWMS compliant with the 1 July 2026 Section 26A changes?
Yes. This SWMS already cites the Codes of Practice that become legally binding under Section 26A of the WHS Act from 1 July 2026, including Managing the Risk of Falls at Workplaces, Construction Work, and Hazardous Manual Tasks. No amendment is required for the transition.
