Temporary Roof Protection JHA (Job Hazard Analysis / Activity Hazard Analysis)
Updated 2026-06-23
A Temporary Roof Protection JHA (Job Hazard Analysis / Activity Hazard Analysis) is the plan that keeps the crew installing temporary roof protection from falling on the exposed roof, being caught by wind handling the coverings, or injured working against incoming weather. Temporary roof protection covers an exposed or in-progress roof to keep water out until permanent roofing is complete — combining the fall hazards of working on the open roof, the wind and weather exposure of handling large coverings, and the material handling. This guide walks through building a Temporary Roof Protection JHA that names the fall, weather-exposure, and material-handling hazards and assigns the fall-protection, weather, and handling controls that hold up in the field.
Why temporary roof protection needs its own JHA
Temporary roof protection installs the temporary weatherproofing — tarps, temporary membranes, dry-in materials, and temporary covers — over an exposed or in-progress roof (after tear-off, during phased re-roofing, or to protect an opening) to keep water out of the building until the permanent roof is complete. It is often installed urgently against incoming weather, on an exposed roof, handling large wind-catching coverings. The hazards combine the falls (working on the exposed, in-progress roof — often with the permanent fall protection not yet in place, and the edges and openings exposed), the wind and weather (large tarps and coverings catch wind — a struck-by, pull-off-balance, and control hazard, and the work is often done against incoming weather, creating time pressure and worsening conditions), the material handling (handling large, bulky coverings and the ballast/fastening), and the slip hazards on the wet or covered surface. The falls and the wind/weather exposure justify a dedicated JHA.
Breaking temporary roof protection into steps
The steps for a Temporary Roof Protection JHA follow the protection:
- Assess the roof, the weather, and the fall protection
- Establish fall protection on the exposed roof
- Stage the covering materials and ballast
- Deploy the temporary covering (managing wind)
- Secure/ballast the covering against wind
- Manage the weather and time pressure
- Verify the protection and drainage
- Maintain the temporary protection
Each step carries a hazard, and the falls, the wind/weather, and the material handling are where the most significant risks concentrate.
The hazards step by step
Falls on the exposed roof
Working on the exposed, in-progress roof carries fall hazards, often with the permanent fall protection not yet in place and the edges and openings exposed (temporary protection is installed during the vulnerable in-progress state). The controls are fall protection appropriate to the exposed roof (personal fall arrest/ restraint, temporary guardrails, warning lines/safety monitor per the roof), protecting exposed edges and openings, and the working-at-height controls maintained during the temporary-protection work. The falls on the exposed roof are a leading hazard. (These follow the roof-work and working-at-height fundamentals.)
Wind and weather exposure
Large tarps and coverings catch wind — a struck-by, pull-off-balance, and control hazard (a large tarp in wind can pull a worker off balance or off the roof), and temporary protection is often installed against incoming weather, creating time pressure and worsening conditions (wind, rain making surfaces slippery). The controls are managing the covering in wind (not deploying large coverings in high wind, controlling the covering, securing progressively, adequate crew), weather assessment and limits (not working in unsafe wind/ weather despite the pressure to dry-in), the wind-management techniques, and not letting the urgency override the fall and weather controls. The wind catching the covering is a specific, defining hazard. (These build on the working-at-height and weather fundamentals.)
Material handling
Handling the large, bulky coverings, the ballast (often heavy — sandbags, pavers), and the fastening carries handling and struck-by hazards. The controls are team handling of the large coverings, safe ballast handling (the heavy ballast), and the material-handling controls. (These follow the material-handling fundamentals.)
Slips on the covered/wet surface
The temporary covering and the wet conditions create slip hazards (tarps and membranes can be slippery, especially wet). The controls are slip awareness on the covering, managing the wet surface, and slip-resistant footwear.

Fall protection and managing wind on the covering
A Temporary Roof Protection JHA centers on fall protection and managing wind on the covering. The fall protection addresses the exposed, in-progress roof — often before permanent protection is in place, with edges and openings exposed — controlled by fall protection appropriate to the exposed roof, protecting edges and openings, and maintaining the controls during the work. Managing wind on the covering addresses the signature hazard — large tarps and coverings catch wind and can pull a worker off balance or off the roof — controlled by not deploying large coverings in high wind, controlling and securing the covering progressively, and weather limits, without letting the urgency of dry-in override the controls. A JHA built on fall protection and managing wind on the covering, with material-handling and slip controls, addresses the hazards that define temporary roof protection.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, temporary roof protection has a specific hazard combination: it is installed on an exposed, in-progress roof, often urgently against incoming weather, using large wind-catching coverings. The falls come first — the roof is exposed and in-progress, frequently with the permanent fall protection not yet in place and the edges and openings exposed, so the temporary-protection work happens during the roof's most vulnerable state. The controls are fall protection appropriate to the exposed roof and protecting the exposed edges and openings.
The wind on the covering is the signature hazard, and it is worsened by the time pressure. Large tarps and coverings catch wind like sails — a large tarp in a gust can pull a worker off balance or off the roof, a struck-by and fall hazard — and temporary protection is often installed against incoming weather, which creates both time pressure and worsening wind and wet conditions. The dangerous combination is a crew rushing to dry-in a roof ahead of a storm, deploying large coverings in rising wind. On the projects I have run, the controls are managing the covering in wind (not deploying large coverings in high wind, controlling the covering, securing progressively with adequate crew), weather assessment and limits, and the discipline not to let the urgency of drying-in override the fall and weather controls. The heavy ballast handling (sandbags, pavers) and the slip hazards on the wet covering round out the hazards. The JHA built on fall protection and managing wind on the covering is the one that protects the temporary-protection crew.
The bottom line
A Temporary Roof Protection JHA names the fall, the weather-exposure, and the material-handling hazards with specific controls — fall protection on the exposed in-progress roof with edges and openings protected, managing the wind-catching covering (not deploying in high wind, securing progressively) with weather limits that the urgency does not override, and safe handling of the coverings and ballast. The falls and the wind on the covering are the defining hazards. The JHA that manages both is the one that protects the crew.
Frequently asked questions
Why are falls a leading hazard in temporary roof protection?
Temporary protection is installed on the exposed, in-progress roof — often with the permanent fall protection not yet in place and the edges and openings exposed, during the roof's most vulnerable state. Controls are fall protection appropriate to the exposed roof (personal fall arrest/restraint, temporary guardrails, warning lines/safety monitor per the roof), protecting exposed edges and openings, and maintaining the working-at-height controls during the work.
Why is wind on the covering the signature hazard?
Large tarps and coverings catch wind like sails — a large tarp in a gust can pull a worker off balance or off the roof (a struck-by and fall hazard) — and temporary protection is often installed against incoming weather with rising wind. Controls are managing the covering in wind (not deploying large coverings in high wind, controlling the covering, securing progressively with adequate crew), weather assessment and limits, and not letting urgency override the controls.
How does time pressure affect the work?
Temporary protection is often installed urgently against incoming weather to dry-in the roof before rain, creating time pressure that can push a crew to deploy large coverings in rising wind and worsening conditions. Controls are weather limits that the urgency does not override, planning and adequate crew, and the discipline to maintain the fall and weather controls despite the pressure to dry-in quickly.
What ballast and handling hazards apply?
Handling the large, bulky coverings and the ballast (often heavy — sandbags, pavers used to hold the covering against wind uplift) carries handling and struck-by hazards. Controls are team handling of the large coverings, safe handling of the heavy ballast, securing progressively, and the material-handling controls.
