Fall protection for roof edges is an indispensable measure to prevent falls (from a height) when working on the roof. From identifying the danger area to the selection of suitable safety systems, it offers comprehensive protection. With the right planning, installation and choice of materials, the roof edge protection system ensures long-term safety and meets the highest standards in the field of fall prevention (protection) systems.
2.5 meter danger zone
The edge of the roof is a significant source of danger, as the risk of falling is particularly high here. According to the planning guidelines of the AUVA, SUVA and DGUV, the area from the roof edge to 2.5 metres inside is considered a danger area. In order to be able to enter this area safely, the roof edge must be secured accordingly with fall protection devices.
The planning guidelines of the AUVA, SUVA and DGUV define how safety measures at the edge of the roof must be designed to meet the highest safety standards. These standards define the danger area and the necessary safety precautions to minimise the risk of accidents. Adherence to these guidelines ensures that edge protection systems meet both legal requirements and the protection of workers.
An overview of roof edge protection systems: restraint or fall arrest systems
There are various methods of securing the roof edge. Either restraint or fall arrest systems can be used.
- Restraint systems prevent people from entering the danger area in the first place.
- Fall arrest systems ensure that people are caught in the event of a fall (from a height).
The use of collective protection is particularly useful if the roof is regularly accessed – including by people without training in the use of PPE – or if there is a high risk of impact due to superstructures or similar in the event of a fall (from a height).
The BARRIER system is ideal for quick and easy installation of collective protection. The elements are simply slotted together, making the system ready for use in no time and ensuring that the roof edge is reliably secured. BARRIER provides a secure hold and can be used as a roof edge protection for flat roofs. BARRIER is also available in a foldable version. For inclined roofs, or steep roofs, other solutions are required, such as cable systems or single anchor points.

Essential criteria for roof edge protection
A roof edge protection system must fulfil several critical requirements in order to ensure reliable and long-term safety. These aspects concern construction as well as installation and servicing.
- Resilience: A roof edge protection system must be able to withstand the various stresses that can be placed on it. This includes the weight of people as well as external influences such as wind pressure and snow load. Only a robust and resilient construction guarantees that the protection remains stable even under extreme conditions.
- Precise installation: Correct installation is of the utmost importance for long-term safety. Systems such as the BARRIER guardrail system are characterised by uncomplicated yet secure installation that can be carried out quickly and efficiently. This reduces the risk of installation errors and ensures that the safety barrier is fully effective.
- Material quality: The choice of materials plays a central role. Roof edge protection should be made of high-quality, weatherproof and durable materials. Stainless metals such as stainless steel or aluminium are ideal because they optimally meet the requirements of outdoor areas and maintain their protective function even under adverse conditions.
There are different design variants for roof edge protection. Overall, it is essential that they are not only carefully planned and installed, but also regularly maintained. This ensures that they permanently fulfil their protective function and that safety on the roof is guaranteed.
Real-life examples
Roof edge protection systems are used in a wide range of projects. For example, they are often used when installing photovoltaic or solar systems to ensure that workers do not fall (from a height) during installation. Roof edge protection systems also provide indispensable protection when servicing air conditioning systems or other technical systems on roofs. Even when inspecting buildings or cleaning roof surfaces, these safety systems ensure that risks are minimised and accidents avoided.
What is the difference between roof edge protection and fall (from a height) prevention (protection) systems?
A roof edge protection system is a special sub-category of fall (from a height) prevention (protection) system that is installed specifically at the edge of a roof to prevent falls (from a height). While a fall prevention (protection) system encompasses a variety of measures that protect people at elevated workplaces, an edge protection system focuses on protection at the edge of the roof and, as mentioned above, can be used as both a collective and an individual protective measure.
As a collective protective measure, an edge protection system creates a physical barrier that prevents people from even entering the hazardous area of the roof edge. At the same time, edge protection can also be part of an individual protection system, in which it is combined with cable systems or other fall arrest devices to specifically secure individuals.
All in all, edge protection is an essential component of a fall prevention (protection) system that can be used in many different contexts to ensure a safe work environment on the roof.
Conclusion
In summary, it can be said that high-quality edge protection systems are an indispensable measure for ensuring safety on roofs. The correct selection, installation and servicing of these safety systems not only minimises the risk of falls (from a height), but also ensures compliance with legal requirements. Whether as part of a collective or individual protection system, edge protection systems offer versatile solutions for a wide range of requirements.
