Quebec City International Airport Creates a Hazard-Free Rooftop

Quebec City International Airport Creates a Hazard-Free Rooftop

The rooftops at international airports are busy with various units requiring routine maintenance. These flat rooftops include several HVAC units, ducts, gas lines, IT-related technology and much more. Creating a hazard-free roof is critical year-round, especially during the winter months when many of the hazards could be covered with snow.

Protecting HVAC Technicians & Roof Workers

Rooftop HVAC units play a big role in keeping a space well-ventilated and comfortable. During the summer months, the outdoor temperatures can reach above 30 degrees Celsius in Quebec City, requiring the HVAC units to be working efficiently 24/7. When a unit is working inefficiently, the space it supports can become uncomfortable, especially when taking into consideration the amount of natural light heating up the space through the building’s big viewing windows. Therefore, when a HVAC unit isn’t working, it requires immediate attention and service. With the unit installed close to the edge of the flat roof, the maintenance team at the Quebec City airport reached out to Skyline Group’s roof safety specialists to discuss a roof safety solution that would create a safe perimeter around the HVAC system.

HVAC Safety Barrier

On this flat roof the HVAC system is slightly more than six feet away from the roof’s edge, so why would a safety solution be required? When a member of the facility maintenance team, or a third-party service worker, is required to be on the roof they need to travel and work in an environment that is within six feet of the roof’s edge. When taking into consideration one’s tools and the need to work from all angles of the HVAC system, you are physically too close to a fall hazard. As a result, the Skyline Group recommended a 5001 series RoofBarrier system that would act as a permanent safety solution, ensuring that regardless of who is on the roof, the risk of falling is eliminated.

Why a Non-Penetrating Roof Barrier

Both penetrating and non-penetrating systems will keep roof workers safe while working on a commercial flat roof, minimizing the risk of injury. The Quebec City airport preferred the 5001 series modular self-ballasted solution due to the following;

  • Being a self-ballasted unit meant that there was no need to fasten the roof barrier to the new rooftop. Eliminating the need for the roof to be resealed from potential leaks.
  • It’s modular design brought various advantages;
    • Easy and quick installation
    • When compared to a welded solution, the 5001 series is extremely easy to transport to the rooftop.
    • Its design allowed for flexibility, as the roof grows with the needs of the airport, so will the safety solution.
  • Its galvanized steel material ensures that the unit will not corrode during the harsh winter months.

Place de Ville high-rise buildings, located in downtown Ottawa, are made up of a few office towers, hotels, and a cinema. The buildings are also linked via an underground shopping complex. Place de Ville C is one of the tallest office buildings in Ottawa, and was referred to as Ottawa’s Toronto Dominion Centre and Montreal’s Place Ville Marie.

Quick & Easy roof guardrail Installation

The facility maintenance team’s primary concern was looking for a non-penetrating self-ballasted rooftop guardrail and barrier system that is quick and easy for the contractor to install. They had originally specified a roof safety guardrail that required to be fastened to the rooftop, and would not only take multiple days to set up but also require a crane rental to bring the material up to the rooftop.

Self-Ballasted Roof Barrier System

Our team proposed the non-penetrating self-ballasted 5003 series RoofBarrier system.

  • Its modular design made the solution extremely easy to transport.
  • The design will also ensure the installation process is quick and easy for the subcontractors, reducing lead time and labor costs.
  • Its lightweight construction allowed for the roof guardrail system to be brought to the roof via the building’s service elevators, eliminating the need for a crane rental in downtown Ottawa.
  • With the 5003 RoofBarrier guardrails being a self-ballasted solution, there was no need for the unit to be fastened to the rooftop. Eliminating the need to make holes into the roof membrane that would have required costly repairs to reseal the roof.

Deciding between a non-penetrating roof barrier and one that is fastened to the roof? Here are five reasons why you would select a non-penetrating roof guardrail solution.

Rooftop Safety Trends – Raising the Bar on Rooftop Safety Compliance

Canadian Roofing Contractors Association interviewed Vernon Ghinn, our VP of roof safety specialists, to chat about the future of height safety and its impact on regulations.



The building design process includes many considerations for serving the occupants working or living within it. And often, the technology required to optimize the building’s safety, comfort, and efficiency end up being installed on the roof. These components may be necessary, but any piece of equipment added to the rooftop poses a degree of risk for those who may need to work in that space. And with rooftop footprints and configurations in constant flux, safety considerations cannot fall through the cracks.

“Like every building component, roof footprint, features, and conditions can evolve; these changes can introduce challenges with accessing equipment,” says Vernon Ghinn, a roof access and safety specialist at Skyline Group. “That’s why rooftop safety isn’t a set it and forget it responsibility; it is something that should be reviewed and improved upon quarterly to ensure you’re staying in compliance and keeping everyone safe.”


Working at height comes with numerous risks. More and more, those risks include having to navigate access points (e.g., ladders or hatches) or rooftop equipment (e.g., HVAC systems, ducts, solar panels) that have been installed throughout the roof and – more frequently – near roof edges.

For example, says Ghinn, “At times, rooftop units are installed at the edge because that happens to be the quickest and easiest location for the installers to place the unit. However, the challenge lies in servicing those units, as a safety solution will be required to create a safe perimeter and working environment.”

Roofing layouts can also pose risks. For instance, flat industrial and commercial roofs can become slippery to walk on when wet depending on the roofing membrane.
Added to these traditional hazards are the ones that appear over time. For example, building upgrades that affect the roof structure and design can also impact its elevations, requiring new roof safety equipment and considerations.

“That’s why it is important to understand the future state of your roof and how the roof is being accessed,” says another safety rep with Skyline. “Corridors are provided inside the building for safe access, so the same consideration should be given to the safety personnel required to keep the building running while accessing the roof.”

Another trend impacting roof safety is that rooftops are becoming more crowded. As land prices rise and available space in populated areas decreases, organizations optimize their investment by making use of their open space. Some of that focus is being turned to rooftops, where building operators turn their rooftop into a publicly accessed area (e.g., a garden or patio) or invest in energy-efficient technologies (e.g., green roofs or solar panels). The result is a very busy environment that requires safer access to all roof areas and increased awareness of common rooftop safety hazards.

“Ultimately, it is important that your roof access and safety solutions stay up to speed with your roof as it goes through different transformations,” adds a Skyline rep.

Roof Guardrail


As building envelopes adapt, so do safety compliance obligations. This is also true of roof and height safety standards, which are constantly adapting to reflect emerging hazards.

“The number of roof fall-related injuries is alarming, so it’s only natural that local and national standards are getting stricter,” says the Skyline safety rep, explaining, “Today, more and more third-party service providers have their own safety guidelines that prevent employees from working on roofs unless the right safety equipment and protocols are in place.”

Aligning with such standards is a critical challenge, especially since failing to keep a building compliant or ensure an installation meets local safety guidelines can lead to severe injuries and costly liabilities. As such, it’s important to recognize hazards as they emerge and never lose sight of one’s safety responsibilities.

“It’s about accessing the roof safely, while working in a hazard-free environment, in order to get back down from the roof safely,” says Ghinn, adding, “The fact is that the number of roof fall-related injuries is alarming, meaning there is room to improve on safety. The good news, though, is that the risks we’re seeing out there today can be mitigated with the right partners and height safety solutions that are readily available.”


No doubt, modern rooftop hazards require modern safety solutions. For example, says the Skyline rep: “We see too many access ladders that are cut short at the bottom, requiring an extension ladder to gain access to the actual roof access ladder itself. This is often done to restrict roof ladder access to the public, but climbing a small ladder to grab the roof access ladder and then climb onto it is simply dangerous. That’s why we developed a lockable gate to block the first five-plus feet of steps and restrict unwanted access.”

The ability to manufacture ladders, guardrails, roof catwalks, and various other rooftop safety solutions in modular sections is also beneficial for today’s contractors. These solutions can be transported to the roof via a service elevator versus renting a crane, while also being installed in a fraction of the time. All while offering the capability to customize a solution that best fits the needs of the roof and local guidelines.

“The savings become quite substantial for all parties,” says Skyline’s rep, explaining, “Our non-penetrating permanent guardrail system, for example, is designed to be modular, making it quick and simple to install without needing to fasten into the existing roof frame. This eliminates the need to reseal the roof membrane for old or newly warranted roofs after an installation.”

Protecting workers and staying in compliance means understanding your rooftop hazards before heading up onto the roof, while having a solution in place to mitigate the risks as they unfold. After all, adds Ghinn, “Nobody should discover safety by accident.”

Ottawa Medical Centre

For more than one hundred years, The Royal has been a community landmark and a beacon of hope for those needing health care. In February 1910, the first tuberculosis patient was admitted to the Lady Grey Hospital, known in the early days as “the San”. In 1969, the facility was renamed the Royal Ottawa Hospital (ROH).

Reviewing Roof Hazards

Like any medical center, the roof of the ROH is crowded with multiple rooftop units that make it challenging to navigate the roof safely. On this roof, the HVAC units were installed towards the center of the rooftop, more than 6 feet away from the edge. With the various gas lines, ducts and other RTUs, the only passage from the roof access point to the HVAC units was a walkway close to the edge of the roof. With the HVAC units requiring routine maintenance, the 50-foot catwalk located adjacent to the roof edge became quite busy with maintenance personnel. With the catwalk being too close to the roof’s edge, a safety barrier and guardrail were specified by the contractor.

Toronto Commercial Rooftop

The McDonald’s Canadian corporate headquarters is located at 1 McDonald’s Place in Toronto. Lennard Commercial Realty manages the commercial property. Their extensive experience and broad expertise, topped by their key connections, make them a great partner for large and small organizations.

Rooftop Safety Plan

To expedite the need for service on their HVAC systems, the original structure was manufactured on-site out of wood. Fast forward a few years later, and Lennard Commercial Realty’s maintenance team had a few safety concerns with their rooftop safety plan and the walkway wood structure. The team identified that the wood structure was non-compliant with local height safety guidelines. It was ultimately rotting away due to the snow and rain penetrating the wood. With the building also being 11 stories high, the structure was subject to high winds, making the walkway and platform system unstable during windy weather.

Lennard’s facility maintenance team was concerned with the current structure not meeting local safety guidelines, ultimately rendering it non-compliant. Even if the system were in perfect condition, it still wouldn’t be considered compliant as it does not meet local height safety regulations.

The facility maintenance team was looking for a permanent solution to provide safe access to the building’s extensive HVAC system. Lennard reached out to our rooftop safety specialists to discuss their safety goals below.

  • The requirement for a permanent solution.
  • The system to be powder coated with a customer yellow color to match the rest of the building and roof.
  • A stocked solution as a quick turnaround would be required.
  • A solution that would be quick and easy to install.
  • An anti-slip walkway and crossover system.
  • A solution that meets both local and TSSA height safety guidelines.

Safety Challenge Requiring Experience

The 460,000 square foot facility on 33 acres produces biologics medicines and Coumadin. Bristol reached out to our rooftop safety specialists to better understand their rooftop safety needs and ensure compliance on a crowded roof. With various large HVAC units, ducts, pipes and more, Bristol was looking to ensure that these RTUs (rooftop units) could be easily maintained. There are many rooftop guardrail, crossover and access ladder providers in North America that can help with meeting safety compliance, although the company was looking for;
  • A modular solution that is quick and easy for the contractor to install.
  • One single supplier that can help provide the required roof safety products and be actively involved in delivering stamped drawings for the basis of design.
  • Has experience working on large-scale design projects, as this project was valued at over $500,000.
  • Can incorporate an aesthetically pleasing guardrail design, limiting visibility from the ground.
  • Most importantly, be certified by a third party to meet hurricane loading requirements. While still requiring a non-penetrating solution to minimize roof damage, repairs, and potential leakage.

Transforming Rooftop Safety

Our team proposed a solution comprised of various galvanized non-penetrating 5003 Series RoofBarrier systems, aluminum crossovers and access ladders. In some areas of the roof, where ducts were located on the edge of the roof, we proposed a fixed guardrail system alongside the parapet. Here is what our solution was able to solve.

  • The 5003 series is considered to be an architectural guardrail. It is a non-penetrating self-ballasted guardrail comprised of curved handrails, making the bars invisible when at ground level.
  • Its modular design and lightweight material ensured a quick and easy installation. While also offering the opportunity to grow their safety needs further, as the roof plans expand to meet production requirements.
  • Our company prides itself on being a one-stop shop to making rooftop safety access and compliance easy. With thousands of projects under our belt and years of experience working with contractors, engineers, consultants and building owners, Bristol felt at ease working with our height specialists.
  • Create a safe passage around the roof, along with to and from each roof access point.
  • We were one of the only suppliers to test this custom non-penetrating guardrail system with up to 60-mile winds with a third party to meet hurricane loading requirements for the area.

5 Reasons Why You Would Select A Non-Penetrating Rooftop Guardrail System

5 Reasons Why You Would Select A Non-Penetrating Rooftop Guardrail System

Both penetrating and non-penetrating systems will keep roof workers (contractors, maintenance staff, and service teams) safe while working on a commercial flat roof, minimizing the risk of injury. Why do facility managers and roofing contractors prefer installing a non-penetrating roof barrier system? Here are 5 common reasons why you would select a non-penetrating rooftop guardrail.

Rooftop Safety


A non-penetrating solution gives you the flexibility to install the system wherever you need it on the roof, regardless of any load barring or structural concerns. This type of system also enables you to reuse the same equipment once a roof is reroofed. Yes, you can do so as well with a fixed guardrail, although the simplicity of just moving the system to the side for a repair to the roof and putting it back in place without making more holes is usually underestimated.

Quick & Easy While Reducing Costs

Our line of RoofBarrier guardrails require less installation time and labor due to their modular design! For contractors, this means you’ll be saving on installation time, labor, and costs. If you are a facility manager, the reduction in labor will contribute towards reducing your overall budgetary requirements.

No Roof Repairs Required

If you plan on fastening the system to the roof, once the installation is complete you will need to repair and/or reseal those sections of the roof. Often the cost of resealing and repairing the flat roof is not taken into consideration when choosing between a fixed guardrail vs non-penetrating guardrail solution.

No Structural Concerns

At times, due to where the barrier needs to be located in order to ensure rooftop safety compliance, fastening a guardrail may not be an option. We have also come across this scenario when working on older buildings and/or historical sites where preserving the site is of utmost importance.

Modular – Growing with Your Roof Needs

As your rooftop grows in either square footage and/or safety requirements, you may require an upgraded HVAC system to meet your growing needs. With a non-penetrating guardrail, you can move the system to a different location on the roof with ease or add onto an existing unit with basic hand tools, ensuring rooftop safety compliance.


Ultimately, it comes down to how quick and easy the installation process is with a modular non-penetrating guardrail system. With a non-penetrating system there is no need for any re-work to be done to the roof after installation is complete, unlike fixed systems where you need to repair and reseal the roof, potentially voiding your roof warranty.
