Assessment Date: [DATE]

Assessor: [ASSESSOR NAME]

Department/Area: [DEPARTMENT/AREA]

Review Date: [REVIEW DATE]

1. Assessment Scope

This risk assessment covers the installation of standing seam roofing systems and associated accessories, including roof access and egress, material handling, lifting and hoisting operations, work at height, edge protection, fall arrest and restraint systems, handling of sharp metal components, weather-related risks, PPE selection and use, permit-to-work controls, emergency preparedness, and rescue arrangements. It applies to roof installation activities on new-build and retrofit projects where workers access roof surfaces, move materials, install panels and accessories, and carry out associated finishing and inspection tasks. The assessment excludes structural roof design, permanent maintenance activities after handover, and any specialist operations not directly related to roofing installation unless they are specifically controlled under the project permit and safe work method. The assessment assumes work is carried out by competent personnel under supervision and that site-specific conditions, including roof pitch, access method, and weather exposure, are verified before work starts.

2. Risk Assessment Methodology

A task-based hazard identification and risk evaluation approach has been used, supported by a 5x5 risk matrix and the hierarchy of controls. Each hazard was assessed for credible consequences, affected persons, initial risk, control measures, and residual risk after controls. The assessment prioritizes elimination and substitution where practicable, followed by engineering controls, administrative controls, and PPE. Roofing-specific controls such as safe roof access, fall protection, protection of openings, material staging, weather restrictions, competent-person oversight, and emergency rescue planning are incorporated into the safe system of work.

3. Risk Matrix Reference

The following matrix is used to evaluate risk levels based on likelihood and severity:

		Likelihood
Rare	Unlikely	Possible	Likely	Almost Certain
Severity	Catastrophic	Low	Low	Low	Low	Medium
Major	Low	Low	Low	Medium	Medium
Moderate	Low	Low	Medium	High	High
Minor	Low	Medium	High	High	Extreme
Negligible	Medium	High	High	Extreme	Extreme

4. Hazard Identification and Risk Evaluation

1. Falls from roof edges, leading edges, and unprotected sides during standing seam panel installation, trimming, fixing, and accessory fitting.

Potential Consequences: A fall from height can result in fatal or life-changing injuries including fractures, spinal injury, traumatic brain injury, internal injuries, and death. Roofing work has a well-documented high severity outcome when fall protection is absent or ineffective.

Affected Persons: Roofing installers, supervisors, apprentices, visitors entering the work area, and persons below the roof line if struck by a falling worker or dropped object.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Catastrophic	Extreme

Control Measures

• Eliminate exposure by completing as much work as possible from ground level, scaffold platforms, or aerial lifts rather than from unprotected roof edges.
• Use engineered edge protection such as guardrails, scaffolds, or properly installed warning-line systems where permitted by roof type and task.
• Provide a personal fall arrest system or fall restraint system with suitable anchorage points designed and installed by a competent or qualified person.
• Restrict access to the roof to authorized workers only and establish controlled access zones and exclusion areas below.
• Require pre-task planning, competent-person supervision, and stop-work authority when conditions change or controls are not in place.
• Use full body harnesses, compatible connectors, and shock-absorbing lanyards or self-retracting lifelines as appropriate for the task.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Catastrophic	High

2. Falls through roof openings, skylights, fragile surfaces, or incomplete roof sections.

Potential Consequences: A worker may fall through an opening or weak surface and suffer fatal trauma or severe injuries. Skylights and openings are especially hazardous because they may not be visually obvious or structurally capable of supporting body weight.

Affected Persons: Roofing workers, maintenance personnel, inspectors, and any person walking on the roof surface.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Catastrophic	Extreme

Control Measures

• Cover all openings with secured, load-rated covers or install guardrails around openings before work begins.
• Treat skylights and any unverified rooflight or fragile panel as openings unless their load-bearing capacity is confirmed by the manufacturer or a competent person.
• Mark openings clearly and maintain a no-step zone around them.
• Inspect the roof deck and substrate before access to confirm structural integrity and identify weak areas.
• Use fall arrest or restraint systems where exposure to openings cannot be fully eliminated.
• Maintain housekeeping so materials, tools, and debris do not obscure openings or create secondary trip hazards.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Rare	Catastrophic	High

3. Unsafe roof access and egress, including ladder misuse, unsecured ladders, inadequate ladder extension, and poor transition between ladder and roof.

Potential Consequences: Workers may fall while climbing, descending, or transferring to the roof, resulting in fractures, head injury, or fatality. Poor access also increases the likelihood of dropped tools and rushed movement.

Affected Persons: Roof workers, delivery personnel, and anyone assisting with access or material transfer.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Major	High

Control Measures

• Provide safe access routes such as secured ladders, scaffold stair towers, or other engineered access systems suitable for the site.
• Ensure ladders are inspected before use, secured against movement, and extend sufficiently above the roof edge for safe transition.
• Maintain three points of contact during ladder use and prohibit carrying loads that prevent safe climbing.
• Position access points away from unprotected edges where practicable and protect the landing area.
• Train workers in ladder selection, setup, inspection, and safe use.
• Suspend access during adverse weather or when surfaces are slippery or unstable.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Major	Medium

4. Manual handling of long, heavy, awkward standing seam panels, flashings, trims, and accessories.

Potential Consequences: Musculoskeletal injuries, strains, sprains, crush injuries to hands and feet, loss of balance, and dropped materials that may injure workers below.

Affected Persons: Roofing installers, ground workers, banksmen, and persons in the drop zone.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Moderate	High

Control Measures

• Use mechanical lifting aids, cranes, hoists, telehandlers, or material lifts where practicable to reduce manual carrying.
• Break loads into manageable bundles and stage materials close to the point of installation.
• Use team lifts for long or awkward items and plan lift paths before moving materials.
• Provide clear communication between lifting team members and the lifting operator.
• Store materials so they cannot slide, topple, or overload roof areas.
• Train workers in safe manual handling techniques and load planning.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Minor	Medium

5. Lifting operations and hoisting of roofing materials to the roof level.

Potential Consequences: Dropped loads, struck-by injuries, crushing, equipment failure, contact with overhead hazards, and uncontrolled movement of materials can cause serious injury or death.

Affected Persons: Riggers, crane or hoist operators, roof workers, ground personnel, and nearby trades.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Major	High

Control Measures

• Use only suitable, inspected lifting equipment operated by competent persons and matched to the load weight and lift plan.
• Establish exclusion zones beneath and around lifting operations and prohibit personnel from standing under suspended loads.
• Use tag lines where appropriate to control load swing and maintain communication using agreed signals or radios.
• Verify load weights, lifting points, and rigging arrangements before each lift.
• Do not overload hoists, cranes, or aerial lifts and do not use damaged or improvised lifting gear.
• Inspect lifting accessories before use and remove defective items from service immediately.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Major	Medium

6. Sharp edges, cut metal, swarf, burrs, and hand-tool contact during cutting, trimming, and fixing of standing seam components.

Potential Consequences: Cuts, lacerations, puncture wounds, eye injuries, infection, and loss of grip leading to dropped materials or falls.

Affected Persons: Roof installers, cutters, fixers, and anyone handling fabricated metal components or waste.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Moderate	High

Control Measures

• Use cut-resistant gloves suitable for sheet metal handling and task-specific eye protection.
• Deburr or fold sharp edges where practicable and handle cut sections with tools rather than bare hands.
• Use correct cutting tools and maintain them in good condition to reduce burr formation and kickback.
• Store offcuts and scrap in designated containers to prevent hand injuries and trip hazards.
• Train workers to recognize sharp-edge hazards and safe handling methods.
• Provide first aid supplies and prompt treatment for cuts and punctures.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Minor	Medium

7. Adverse weather conditions including rain, wind, frost, ice, lightning, poor visibility, and extreme heat or cold.

Potential Consequences: Slips, loss of balance, reduced grip, heat stress, cold stress, dehydration, impaired judgment, and increased fall or struck-by risk. Wet metal roofs and windy conditions significantly increase the likelihood of serious incidents.

Affected Persons: All roof workers, supervisors, lifting crews, and persons below the work area.

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Major	High

Control Measures

• Stop roof work during unsafe weather conditions such as rain, high winds, lightning, frost, ice, or poor visibility.
• Inspect roof surfaces before work and after weather changes to confirm footing remains safe.
• Use slip-resistant footwear and maintain dry, clean access routes where possible.
• Adjust work sequencing to avoid exposed edge work during marginal weather.
• Provide weather monitoring and empower supervisors to suspend work immediately when conditions deteriorate.
• Implement hydration, rest, and thermal protection measures for hot or cold conditions.

5. General Control Measures

• Implement a permit-to-work and pre-start authorization process for roof access and work at height.

The permit should confirm roof condition, access arrangements, weather suitability, fall protection readiness, rescue arrangements, and exclusion zones before work begins.

• Use competent-person supervision and daily task briefings.

A competent supervisor should verify controls, coordinate trades, and stop work if conditions change or unsafe acts are observed.

• Maintain strict housekeeping and material staging controls.

Keep walkways clear, stage materials away from edges, secure loose items, and remove waste regularly to reduce slips, trips, and dropped-object hazards.

• Establish exclusion zones below roof work and lifting operations.

Barricade the area beneath active work, post warning signage, and prevent unauthorized access by workers, visitors, and the public.

• Inspect all access equipment, fall protection equipment, and lifting gear before use.

Remove defective equipment from service immediately and ensure inspection records are retained in accordance with site procedures.

6. Emergency Preparedness

• A site-specific rescue plan shall be in place before any worker is exposed to fall hazards. The plan must address prompt rescue from suspension trauma, access to the roof, communication methods, and the roles of the rescue team, supervisor, and first aider.
• Emergency response arrangements shall include immediate raising of the alarm, stopping work, securing the area, and contacting emergency services when a fall, serious injury, or entrapment occurs.
• Rescue equipment suitable for the roof configuration shall be available on site, including means to reach a suspended or injured worker without exposing rescuers to additional fall hazards.
• Workers shall be trained not to attempt an unsafe rescue. Only trained personnel using the planned rescue method may carry out recovery operations.
• First aid provisions shall be available for cuts, crush injuries, fractures, heat stress, and shock, and the route for ambulance access shall be kept clear at all times.

7. Training Requirements

• Working at Height and Fall Protection Training: All roof workers shall be trained in fall hazards, roof-edge protection, opening protection, PFAS use, restraint systems, anchorage limitations, and the correct response to changing conditions. Training must include practical fitting and inspection of harnesses, lanyards, and connectors.

  • Set ladders at the correct angle and secure them against movement.
  • Ensure ladders extend adequately above the landing point.
  • Use safe transfer techniques when stepping on and off the roof.
• Manual Handling and Material Staging Training: Workers shall be trained to assess load weight, plan lifts, use team handling where needed, and stage materials to prevent slips, trips, and dropped objects. Training should cover safe movement of long metal panels and accessories.
  • Plan routes before moving materials.
  • Use mechanical aids where practicable.
  • Keep materials clear of edges and walkways.
• Lifting Operations and Rigging Awareness: Personnel involved in hoisting or receiving materials shall be trained in lift planning, exclusion zones, communication signals, load control, and the hazards of suspended loads. Only competent persons should direct lifting operations.
  • Verify load weight and lifting points.
  • Use tag lines and exclusion zones.
  • Never stand under suspended loads.
• Emergency Rescue and Incident Response Training: Workers and supervisors shall be trained in the site rescue plan, alarm raising, emergency communications, and the actions required after a fall, including suspension trauma awareness and first aid priorities.
  • Know who to contact and how to raise the alarm.
  • Understand the rescue sequence and equipment location.
  • Do not improvise rescue methods outside the plan.

8. Monitoring and Review

Review Frequency: Annually, and immediately after any fall, near miss, significant weather event, change in roof design, change in access method, or introduction of new equipment or work methods.

Monitoring Type	Frequency	Responsible Party	Description
Regular Inspection	Before work starts each shift and after any weather change	Competent supervisor	Inspect roof condition, access equipment, edge protection, openings, housekeeping, and weather suitability before authorizing work to proceed.
PPE and Fall Protection Check	Before each use	Each worker and the supervisor	Verify harnesses, lanyards, connectors, anchors, helmets, gloves, footwear, and eye protection are serviceable, correctly fitted, and appropriate for the task.
Workplace Audit	Weekly and after any incident or near miss	Site management and safety representative	Audit compliance with the permit-to-work system, exclusion zones, material staging, lifting controls, and rescue readiness. Record corrective actions and close them out promptly.
Weather Monitoring	Continuous during roof work and formally before each shift	Supervisor or designated competent person	Monitor wind, rain, lightning, frost, heat, and visibility. Suspend work when conditions exceed safe limits or when footing becomes unreliable.
Training and Competency Review	At induction, when tasks change, and annually	Employer and training coordinator	Confirm workers remain competent in fall protection, ladder safety, manual handling, lifting awareness, and emergency procedures. Refresh training after incidents or when new equipment is introduced.

9. Special Circumstances

• Wet, icy, or windy conditions significantly increase slip and fall risk on standing seam roofing and may require work to stop until conditions improve.
• Night work or poor visibility increases the likelihood of missteps, dropped objects, and communication failures; enhanced lighting and supervision are required if such work is unavoidable.
• Lone work should be avoided for roof installation activities because rescue from height may be delayed and supervision is reduced.
• Steep pitch roofs, fragile substrates, and roofs with skylights or openings require additional fall protection and stricter access control.
• Hot weather can cause fatigue and reduced concentration, while cold weather can reduce dexterity and increase slip risk; work-rest and hydration controls must be adjusted accordingly.
