Step 1 of 4 · Working draft
Your job
Tell Jenkins what you’re planning and where the work will happen. Use the actual job details.
Use the published example’s suggestions when they fit your task, or write your own steps. These are planned controls, not verified worksite conditions.
Describe an observable step, how someone could be harmed, and the control that acts on that hazard. Identify who checks it and what evidence is needed.
Walk through the plan with the people doing the work. Resolve missing controls and agree who checks them. Moving to the next step does not approve the work.
Confirm people, equipment and emergency arrangements
Record changes, checks, and open actions
Walk the work area, review with the crew, and resolve missing controls. Follow the required approval process. This tool does not judge completeness, verify signatures or authorize work.

Your Asphalt Shingle Roof Installation JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Release the pitched roof work area
Possible hazards: A weak deck or incomplete fall system can cause a fall or collapse.
Planned controls: Roofing lead confirms deck/underlayment handover and the selected fall-protection, access and rescue arrangements. Walk only the released protected route; correct exposed holes or unsuitable anchors before work.
Check before work: Lead checks the complete access-to-installation route.
022. Load and stage bundles
Possible hazards: Heavy bundles can overload the roof or slide onto workers below.
Planned controls: Use the planned hoisting/delivery method and permitted stack locations. Restrain stock for the slope and conditions, keep eaves clear and separate the ground drop zone.
Check before work: Material lead verifies load distribution and bundle stability.
033. Arrange work positions and tools
Possible hazards: Poor footing or hose routing can pull a worker off balance.
Planned controls: Use the selected protected work-position arrangement and tool instructions. Route hoses/cords away from travel and fall-system interference; never use an unapproved makeshift platform to compensate for the slope.
Check before work: Foreperson checks footing and tool/fall-system interfaces before fastening.
044. Lay and fasten shingles
Possible hazards: Fastening, sharp edges and awkward reaching can injure workers.
Planned controls: Follow product layout and fastening details from protected positions. Keep hands outside the nail path, use the actual nailer’s safe mode and controls, and advance material without reaching beyond stable footing.
Check before work: Installer checks tool operation and product fastening as work advances.
055. Complete transitions and ridge work
Possible hazards: Changing slope or reaching the ridge can defeat the earlier protection arrangement.
Planned controls: Reassess the protected position before ridge, hip or transition work. Use the system’s details and permitted access; hold any task that requires an unplanned anchor transfer or unprotected edge approach.
Check before work: Lead verifies protection for each changed work position.
066. Clear and hand over the roof
Possible hazards: Loose fasteners, offcuts or unsealed work can expose later crews.
Planned controls: Collect debris without sweeping it over the edge, secure remaining materials and communicate incomplete flashing or product sealing work. Leave required access/protection in place for the next task.
Check before work: Lead checks the roof and ground zone before release.
Example scope and starting conditions
A roofing crew will install asphalt shingles on a released pitched wood roof at a new low-rise building. The deck and underlayment are already prepared, and conventional fall protection and safe access are installed. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The actual slope, surface, anchors and work-position arrangement are evaluated before roof access.
- Roof-load limits, shingle product instructions and fastening details govern staging and installation.
- Tear-off, deck repair, roof-truss work, safety-monitor-only methods and improvised toe boards are excluded.
Know when to pause
- Wet, icy, dusty or wind-affected surfaces impair control.
- Deck, loading or anchor/protection conditions differ from the release.
- Tool, material or ridge transition cannot be managed from protected positions.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting.
Free example and template
No account required. The worked example contains planned controls. The blank template is for your own work; neither includes fabricated inspection results, signatures or approval.

For managers
Does the team have what it needs to carry out the plan? Give the crew time, equipment and support, and make it clear who will resolve anything that is missing.
Manager checks and supporting resources
Confirm the people doing the work have the time, equipment, information and support to carry out the plan. Agree who checks the controls and who resolves open actions.
Questions to resolve before work
- Which fall system protects every access and installation position?
- How are shingle bundles loaded and restrained within roof limits?
- What surface or weather conditions require the crew to leave the roof?
Training and qualifications to confirm
- Applicable roof fall-protection training, anchor use and task-specific rescue planning.
- Shingle product, load staging and actual roofing nailer instruction.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Does roof slope make a warning line sufficient for this job?
Do not apply low-slope roofing options to pitched/steep-slope work by assumption. Select the protection required for the actual slope and operation. This example uses conventional protection planned for every position.
What must the crew record for actual use?
Identify the actual equipment and work boundaries, responsible people, applicable criteria, inspection findings and open actions. Resolve changes with affected crews and obtain required project authorization before work.

Task-by-task control and verification rationale
1. Release the pitched roof work area
Hazard: A weak deck or incomplete fall system can cause a fall or collapse.
Control: Roofing lead confirms deck/underlayment handover and the selected fall-protection, access and rescue arrangements. Walk only the released protected route; correct exposed holes or unsuitable anchors before work.
Verification: Lead checks the complete access-to-installation route.
Why this belongs in the analysis: Roof preparation and safe work access require separate evidence.
2. Load and stage bundles
Hazard: Heavy bundles can overload the roof or slide onto workers below.
Control: Use the planned hoisting/delivery method and permitted stack locations. Restrain stock for the slope and conditions, keep eaves clear and separate the ground drop zone.
Verification: Material lead verifies load distribution and bundle stability.
Why this belongs in the analysis: Roof slope changes the material’s storage behavior.
3. Arrange work positions and tools
Hazard: Poor footing or hose routing can pull a worker off balance.
Control: Use the selected protected work-position arrangement and tool instructions. Route hoses/cords away from travel and fall-system interference; never use an unapproved makeshift platform to compensate for the slope.
Verification: Foreperson checks footing and tool/fall-system interfaces before fastening.
Why this belongs in the analysis: The work position must accommodate the actual slope.
4. Lay and fasten shingles
Hazard: Fastening, sharp edges and awkward reaching can injure workers.
Control: Follow product layout and fastening details from protected positions. Keep hands outside the nail path, use the actual nailer’s safe mode and controls, and advance material without reaching beyond stable footing.
Verification: Installer checks tool operation and product fastening as work advances.
Why this belongs in the analysis: A fastening pattern does not replace nailer or fall controls.
5. Complete transitions and ridge work
Hazard: Changing slope or reaching the ridge can defeat the earlier protection arrangement.
Control: Reassess the protected position before ridge, hip or transition work. Use the system’s details and permitted access; hold any task that requires an unplanned anchor transfer or unprotected edge approach.
Verification: Lead verifies protection for each changed work position.
Why this belongs in the analysis: The final roof courses may create a different fall route.
6. Clear and hand over the roof
Hazard: Loose fasteners, offcuts or unsealed work can expose later crews.
Control: Collect debris without sweeping it over the edge, secure remaining materials and communicate incomplete flashing or product sealing work. Leave required access/protection in place for the next task.
Verification: Lead checks the roof and ground zone before release.
Why this belongs in the analysis: Cleanup must maintain the same roof and falling-object protection.

Common questions
Can this example be used as a JSA?
Adapt its Task | Hazard | Control analysis to the employer’s format and actual conditions. The example is a teaching aid, not evidence that controls were checked.
What changes if the project requires an AHA?
Use the governing AHA format, risk method, supporting records and acceptance process. The published formwork AHA demonstrates that additional structure; changing a JHA title does not supply it.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
