Roof hatches play an essential role in commercial, industrial and institutional buildings, allowing access to rooftops for inspections, HVAC maintenance or equipment installations. However, unprotected hatches are among the leading fall hazards in Ontario workplaces, presenting severe risks to workers at height. That’s why we’ve created an extensive guide to roof hatches, exploring their safety risks, Ontario’s regulatory framework and practical solutions that help building owners and facility managers protect their teams.
Before we explore these rooftop features in detail, let’s look at some of the key statistics, and some of the human stories behind the real risks of roof hatches. A statistic we often highlight is that in 2022/23, 18 deaths in Ontario were caused by falls from height. While these fall take many forms and have many different causes, roof hatches are a major contributor to these statistics.
In one tragic case, a worker suffered serious injuries while preparing for a roofing job. Workers did not realize the plywood was being used to cover a hole that had been cut in the roof for mechanical services to the building. As they moved the plywood, one worker fell through the hole, approximately eight metres. While a roof hatch wasn’t in use, it draws us back to that key danger: an exposed opening on a flat roof without sufficient protection.
As with most rooftop safety risks, this could have been avoided with the correct approach to safety installations. But what risks are unique to roof hatches?
Understanding Roof Hatch Safety Risks
A poorly managed roof hatch is a major hazard. Without proper safeguards, workers can fall into the opening or off the roof, leading to severe injuries or fatalities. Below are the primary risks associated with roof hatches:
1. Fall Hazards Due to Open Roof Hatches
Open roof hatches pose a significant fall risk if not secured or protected by a guardrail system. Workers accessing or exiting the rooftop may lose balance and fall through the opening. It is crucial to consider that incidents involving unprotected hatches often result in severe injuries or fatalities.
2. Trip and Slip Risks Around Roof Hatches
Raised hatch curbs can create tripping hazards if workers are unaware of their presence. Meanwhile, wet, icy or snow-covered surfaces around the hatch increase slip risks, particularly in Ontario’s winter conditions. In darker seasons, poor visibility in low-light conditions further exacerbates trip risks. The risks here are numerous and highly significant.
3. Risks Associated with Unauthorized Access
Roof hatches that are not locked or secured properly can be accessed by unauthorized personnel, leading to safety breaches. This raises an important issue that you shouldn’t only consider the safety of your teams, but the security of your building. The two concepts go hand-in-hand. with potential vandalism or improper use of the hatch creating liability concerns for facility managers.
4. Improper Use of Ladders and Entry Points
Fixed ladders leading to roof hatches may lack sufficient safety features like handrails, anti-slip rungs or lifelines. The danger here is amplified when workers may be carrying heavy tools or equipment, reducing their ability to maintain three points of contact when using a ladder. From a broader perspective, hatch doors that do not open fully can obstruct entry and create awkward maneuvering, increasing fall risks.
5. Environmental Exposure and Weather-Related Risks
As a property owner or manager, you’ll understand that Ontario experiences extreme seasonal changes, affecting roof hatch safety. Winter conditions lead to ice buildup, making ladder rungs and surrounding areas dangerously slippery. Meanwhile, high winds can suddenly slam hatch covers shut, potentially trapping workers or causing head injuries.
How to Enhance Safety Around Roof Hatches
To minimize risks and ensure compliance, facility managers should implement a combination of engineered safety controls, procedural safeguards, and proper equipment:
- Install roof hatch guardrails: One of the most effective ways to prevent falls around roof hatches is to install a guardrail system. A permanent or non-penetrating guardrail provides a protective barrier, ensuring workers are safe when entering or exiting the hatch. Skyline Group’s range of roof hatch guardrails are self-standing, with non-penetrating designs available. They comply with OHSA and Ontario Building Code and are easy to install without roof membrane damage.
- Use self-closing safety gates: A self-closing gate ensures that the hatch opening is never left exposed, eliminating fall hazards when workers are transitioning between the ladder and the rooftop.
- Use properly designed roof hatch ladders: Many safety incidents occur due to unsafe ladder access to roof hatches. Facility managers should ensure ladders are equipped with anti-slip rungs for better grip, fitted with lifeline systems to prevent falls and properly secured to avoid shifting or movement. Our selection of fixed access ladders are designed for seamless integration with roof hatches and are available with anti-slip rungs and fall arrest systems. Crucially, they also meet OHSA and OBC safety requirements.
- Implement access control measures: Lockable roof hatches prevent unauthorized personnel from accessing the roof. Aside from taking this step, restricted keycard or keypad entry systems enhance security. As a final line of defense, surveillance cameras help monitor unauthorized access.
- Conducting routine inspections and maintenance: You should regularly check for corrosion, wear and damage on hatches, ladders and guardrails. This includes ensuring hatch doors operate smoothly and remain securely fastened when closed. As a property owner or manager, you should schedule professional inspections at least twice a year, especially before winter.
Roof Hatch Safety: Skyline Group’s Success Stories
Skyline Group has a proven track record of delivering innovative, compliant, and highly effective roof hatch safety solutions for commercial buildings across Ontario. Below, we explore two of our standout success stories, demonstrating how our solutions have helped businesses overcome complex rooftop safety challenges.
Enhancing Safety and Compliance for a Walmart
Walmart needed a safer way for maintenance teams to access the rooftop via a roof hatch while ensuring compliance with Ontario’s safety regulations. Skyline Group provided a comprehensive solution, including self-closing roof hatch safety gates, non-penetrating guardrails, and anti-slip walkways, significantly reducing fall risks. This upgrade ensured full compliance with workplace safety standards, protected workers, and maintained the integrity of the rooftop without requiring invasive modifications.
Safe and Efficient Interior Access for a Commercial Building
A commercial building required a secure interior rooftop access system to replace unsafe exterior ladders. Skyline Group installed a modular aluminum access ladder with a lockable roof hatch, along with perimeter guardrails and a self-closing safety gate to prevent falls. This solution eliminated weather-related hazards, allowed for safe equipment transport, and ensured compliance with Ontario’s OHSA rooftop safety requirements, ultimately streamlining maintenance operations and protecting workers.
Property Managers and Owners: The Responsibility is Yours
A proactive approach to roof hatch safety is critical, as waiting until an accident happens can lead to severe injuries, compliance violations, and costly legal consequences.
Beyond compliance, proactive investments in rooftop safety improve efficiency by reducing workplace disruptions and ensuring maintenance teams can work confidently. Solutions like perimeter guardrails, anti-slip walkways, and secure ladder access help create a safer environment, preventing accidents before they happen.
