In the construction industry and wider built environment, providing a safe and compliant rooftop access solution is not optional. It’s a legal and moral responsibility. One question often asked when designing a roof walkway system is this: Do we need guardrails?
The answer depends on one key factor: whether you require collective protection.
When using a system like Kee Walk, which already improves safety by providing clear, slip-resistant rooftop access, adding a guardrail transforms it into a collective protection measure. This blog will explain what that means, when it’s required, and how it differs from personal protective measures like lifelines and PPE.
What Is Collective Protection?
Collective protection refers to safety systems that protect more than one person at once, without requiring individual user input or special training. A physical barrier, like a guardrail, is a prime example. It provides edge protection for any worker accessing the roof, whether they’re trained or not.
Unlike personal protective equipment (PPE), which requires proper fitting, anchorage, and supervision, collective measures work automatically. They should always be considered a priority during risk assessments and are the preferred approach under UK Work at Height Regulations.
Kee Walk as a Standalone Roof Walkway System
On its own, Kee Walk offers a compliant roof walkway system. It provides a defined, slip-resistant path across rooftops of all types including sloped, standing seam, and membrane surfaces. It also helps to:
- Prevent falling objects by reducing the need for improvised paths
- Protect the roof surface from damage due to foot traffic
- Support regular access for maintenance without compromising the structure
While effective, Kee Walk without guardrails is not considered a collective protection system. Instead, it supports personal measures, like rope access systems or a ppe lanyard attached to an anchorage point.
When Is Collective Protection Required?
Adding guardrails to your roof walkway system is necessary when:
- Workers are within 2 metres of an unprotected edge
- There is no parapet or permanent edge protection
- Access is frequent or involves multiple personnel
- Risk assessments identify inadequate control via personal protection
In these scenarios, relying solely on personal protective measures is not considered sufficient. A collective solution ensures anyone, regardless of training, can work effectively without harm.
Why Guardrails Make a Difference
When you add guardrails to Kee Walk, it becomes a full collective protection measure. The result is:
- A fully enclosed roof walkway system that prevents falls
- A system that requires no specialist PPE
- Protection for any person accessing the roof including contractors, inspectors, or in-house teams
This level of protection eliminates many of the variables that come with personal protective equipment such as fitting, inspection, training, and human error.
When Personal Protective Measures Are Still Appropriate
Not all rooftops require guardrails. Personal protective systems are still useful where:
- Aesthetic concerns prevent the use of visible guardrails
- Access is rare or limited to trained personnel
- Rope access systems are more practical for temporary work
However, even in these cases, collective measures should be considered first. As the Hierarchy of Control reminds us: avoid the risk, then use collective controls, and finally personal controls only when all else isn’t feasible.
Kee Walk + Guardrail = Complete Safety System
By combining Kee Walk with a modular guardrail, you create a roof walkway system that delivers:
- Collective protection with no need for harnesses
- Control measures that work without constant supervision
- A safer, more compliant working environment for all employees
It’s an ideal solution for maintenance zones, regular access routes, or any roof area where multiple workers may be present.
Final Thoughts: Choosing the Right Level of Protection
When evaluating protective measures for your rooftop, it’s essential to consider both the risks and the consequences. The decision between collective and personal protection should not be based on cost alone but on the ability to protect workers effectively.
A roof walkway system like Kee Walk, when paired with integrated guardrails, is a compliant, modular, and proven method to deliver safe access without relying solely on individual personal protective behaviours.

Kee Walk with Guardrail FAQs
1. What is collective protection on rooftops?
Collective protection is a safety system that protects multiple people at once without the need for personal protective equipment. Guardrails on a roof walkway system are a prime example.
2. When is a guardrail required on a roof walkway system?
Guardrails are required when workers operate near an unprotected edge, there is no parapet, or the area sees regular access. In these cases, collective protection is considered a priority control measure.
3. What’s the difference between collective protection and personal protective measures?
Collective protection, like guardrails or safety nets, protects all users by default. Personal protective measures, such as a ppe lanyard or harness, require training and individual use.
4. Does Kee Walk provide protection without a guardrail?
Yes. Kee Walk is a compliant roof walkway system that offers slip resistance and protects the roof surface. However, without guardrails, it is not a collective protection system and should be used with personal fall protection.
5. Can I use Kee Walk with other fall protection systems?
Absolutely. Kee Walk can be integrated with personal systems like Kee Line or combined with guardrails for full collective edge protection.
6. How do I know if collective measures are required on my roof?
A risk assessment should be conducted. If there’s frequent access, multiple users, or work near an unprotected edge, collective protection is typically required by height safety regulations.
