5 Common Roof Safety Hazards

To protect roofers, contractors, and subcontractors from serious injuries and fatalities, it’s important to identify hazards when working on rooftops and follow critical safety steps to control them. Below are the most common rooftop hazards that should be identified and controlled to keep roofers safe:

• Fall Hazards – Always watch out for fall hazards when working at heights and prepare yourself with the right harnessing and fall protection gear before working.
• Power Tools – If improperly used at heights, power tools can inflict serious damage to workers as well as cause slips and falls. Hence, ensure your team is properly trained to handle power tools.
• Electricity – Workers, especially those on rooftops and near power lines, are highly exposed to electrical hazards. To control possible causes of electrocution and prevent accidents, conduct regular electrical safety checks.
• Hazardous Substances – Check for common hazardous substances, such as asbestos, paint fumes, and other harmful chemicals, that may pose risks to workers on-site and take appropriate action including proper storage and safe handling of hazardous substances.
• Extreme Temperatures – Workers must be protected from the dangers of extreme temperature by identifying the risks brought by equipment or current weather conditions. Have your team perform a toolbox talk before your shift to decide whether you should commence work for the day.

Roof Safety Signs and Their Meaning

According to OSHA, safety signs are generally categorized into three types—danger signs, warning signs, and caution signs. When working on rooftops, roofers will usually encounter the following examples of roof safety signs and what they should do:

Danger Sign

When there is a roof safety danger sign, there are immediate hazardous conditions that will lead to serious injury and death if not avoided. Upon seeing this sign before any roofing work, avoid it at all costs.

Warning Sign

When there’s a roof safety warning sign, there are existing life-threatening hazards that can lead to serious injury or death. Accessing roofs by permit means that only authorized personnel or trained employees can be on them. Warning signs represent a hazard level between danger and caution, needing specific precautionary measures to be taken.

Caution Sign

When there’s a roof safety caution sign, there are minor hazard situations where a non-immediate or potential hazard or unsafe practice presents a lesser threat of employee injury. Roofers should be mindful of caution signs and apply necessary control measures in any roofing work.

Top 10 Roofing Safety Tips

1. Always begin with your 5-10 minute pre-start talk:Discuss common hazards present (like the common hazards above), assess the condition of the work area, confirm that proper permits have been secured, and encourage the team to verbalize the safety tips to follow.
2. Work only during good weather conditions and avoid extreme heat/cold: Better side with caution and always wait for ideal weather before you begin roofing work to avoid slips and falls.
3. Ladders should be stable and properly secured or tied off: Always ensure there are enough ladders and scaffolding for the job and that they’re all safe to use. Check your ladders for safety, repair, or replacement needs to prevent fatal accidents or injuries.
4. Wear proper Personal Protective Equipment (PPE): Wearing adequate PPE such as helmets, shoes with traction, and fall protection harnesses can help save you when slips and falls occur. Perform regular PPE checks to ensure your team is properly equipped.
5. Carefully position ropes and extension cords so they’re not underfoot: When not properly handled, ropes and cords can hinder workers’ movements and cause fatal accidents. Always follow proper use of ropes, cords, and safety harnesses.
6. Sweep the roof before and after work and ensure it’s clear of dirt and debris: Always keep the roof clean and free of items that can cause accidents or materials that can hinder the roof’s visibility
7. Use guardrails whenever possible: Guardrails serve as a visual and physical barrier that protects workers from falls. It reduces the risk of injury and death from working on roofs.
8. Skylights should be guarded appropriately: Skylights and other openings on roofs should be properly covered and labeled with visible warning signs to prevent workers from leaning on or falling into them.
9. Be careful of slate and tile roofs: Workers must be properly trained and have enough experience to work on slate and tile roofs as these are considered major slip hazards.
10. Signages should be visible in your work area: People around the work area should always be aware of roofing work in the vicinity by using visible warning signs to prevent injury or accidents with staff working on-site or from falling debris.

Roof Safety Topics for Meetings

As the topmost safety precaution for working on roofs, pre-start talks should be performed. Listed below are sample roof safety topics for meetings prior to commencing roofing work:

• Working with Skylights and Roof Openings
• Basic Roof Housekeeping Standards
• Demonstrating the Proper Operation of Roof Cutters and Power Brooms
• Safety Measures for Job-built Ladders
• Identifying Potential Heat Illnesses and How to Avoid Them
• Pre-use Checks for Specific Roofing Equipment
• Proactively Preventing Horseplay to Avoid Slips, Trips, and Falls
