Roof Anchors vs Guardrails: A Roof Safety Comparison

Roof Anchors vs Guardrails: A Roof Safety Comparison

Regardless of your industry, creating a safe working environment on rooftops is crucial from both legal and ethical standpoints. At Skyline Group, we see roof anchors and guardrails as two fundamentally different approaches to achieving this objective. In an expert learning resource, our safety specialists explore the varying benefits and applications of these fall arrest systems, helping commercial building owners, contractors, and others make informed height safety related decisions.

While both systems can play vital roles in fall protection protocols, their value will largely depend on the nature of your rooftop and the level of access your teams require. Let’s explore the details of these solutions, starting with Roof Anchors.


Roof Anchors: Active Fall Protection

Roof anchors – commonly referred to as horizontal or vertical lifelines – represent an integral part of an active fall protection system. Roof anchors will typically require the worker to use an array of personal protective equipment (PPE) such as harnesses and lanyards. Fundamentally, these solutions will serve as secure points at which workers at height can reliably attach their safety equipment.

Roof Anchors: Key Features

Roof anchors provide a number of unique advantages, primarily around the customizability and strength they can offer:

  • Movement with flexibility: Unlike some alternative fall arrest systems, roof anchors provide a great degree of freedom when navigating the roof. This makes them an ideal solution for maintenance teams that require mobility across large elevated workspaces. You are essentially limited to the length of the wire or line you are connected to.
  • Customization options: Like guardrails, roof anchors can be installed as permanent fixtures for regular maintenance tasks or as a temporary solution for specific projects.
  • Requirements: Requirements may vary by province, but it is important to note that strict guidelines and capacity-based requirements must be adhered to when connecting to an anchor point.

Anchors are considered active fall protection, so you are essentially using the system when a fall occurs, which will indeed save your life. But should a fall have happened in the first place? This solution also places the responsibility on the employee or contractor to utilize the equipment correctly, which can sometimes be neglected for various reasons.


Guardrails: Passive Fall Protection

Unlike roof anchors, guardrails represent a passive approach to fall protection, requiring no active input from workers to ensure their own safety. Naturally, guardrails are particularly effective when providing collective protection for many workers on a rooftop at one time. The intention is to eliminate or minimize the risk of a fall from occurring in the first place. Let’s take a look at their unique advantages.

Guardrails: Key Features

  • Continuous protection: Once guardrail systems are installed, they offer immediate protection without the need for workers to attach PPE (however, it is important to remember that wearing PPE is always beneficial for height safety, regardless of the fall arrest systems being used).
  • Simple and compliant: Guardrails designed to meet Canada’s OHSA standards can withstand specific lateral and vertical forces, guaranteeing enhanced safety without the need for extensive training (however, again it is important to remember the benefits of comprehensive training to ensure a culture of safety in your organization).
  • Permanent solution: Often used as a long-term solution, guardrails are installed around the perimeter of the roof or near rooftop hazards.


Elevated Safety: Comparing Roof Anchors & Guardrails 

As mentioned, roof anchors and guardrails provide unique benefits depending on your rooftop’s requirements. Keep reading for insights on how these systems compare in terms of installation and maintenance, cost-effectiveness, safety and compliance, and general industry applications.

Comparing Installation & Maintenance

  • Roof Anchors: Require precise installation and periodic inspections to ensure they remain securely attached and tested to support the required loads.
  • Guardrails Require less maintenance over time. Once installed, they do not require frequent inspections or recertification; they require solely a visual inspection that can be done by a member of your maintenance team or a contractor.

Comparing Cost-Effectiveness

  • Roof Anchors: May appear less expensive initially, especially for smaller areas or shorter-term projects. However, the need for PPE and training, along with periodic inspections, can add to the overall cost.
  • Guardrails: Can represent a significant initial investment but offer reduced long-term costs due to minimal maintenance requirements.

Comparing Safety & Compliance 

Both systems must comply with rigorous safety standards. Choosing between them often depends on the specific requirements of the job site, the nature of the work, and the company’s safety culture.

For guidance on legal requirements across Canada, consult our extensive Roof Fall Protection & Height Safety Regulations resource page.

That being said, guardrails are the primary option of choice for contractors because they proactively enable safety for every worker at height. The goal is to minimize the risk of injury at the source by either removing or limiting access to the hazard, allowing work to continue safely around those areas of concern.

Comparing Applications 

  • Roof Anchors: Best suited for jobs that require extensive movement across a roof where edge protection is not feasible.
  • Guardrails: Ideal for providing a barrier around the perimeter of a roof or near roof hatches and other hazardous areas to minimize the risk of a fall.


Beyond Compliance: Advanced Fall Protection Systems

While guardrails and anchors may help organizations meet the minimum legal standards for workplace safety, achieving compliance does not guarantee complete safety for workers at height.

Advanced fall protection systems are essential to truly safeguard these workers, urging a move beyond just meeting the bare minimum. It is critical for safety measures to not only satisfy legal requirements but to exceed them, ensuring a safer and more secure working environment where the risk of accidents is significantly minimized.
