Permanent Fall Protection on Flat Roofs: When It's Mandatory and What It Must Achieve
Fall protection on flat roofs that are regularly accessed must meet two requirements simultaneously: it should provide maximum protection – and impede daily work as little as possible. Permanent systems are designed precisely for this purpose. They are permanently installed, tested once, and offer immediate protection every time they are accessed, without any setup or dismantling effort.
When is permanent fall protection sensible?
The decision between a temporary and permanent solution depends on the frequency of access. A flat roof that is accessed once a year for gutter cleaning does not require a permanent installation. A roof with a PV system, air conditioning, or other maintenance-intensive installations, which is accessed monthly or more frequently, is a clear case for permanent solutions.
The revised DGUV Information 201-056 (September 2025) explicitly makes this distinction through equipment classes AK-A to AK-C: the higher the intensity of use, the higher the requirements for the protection system.
Permanent roof edge protection: What differentiates it from temporary systems
Permanent railings and side protection systems are structurally attached to the building – either to the parapet, the roof edge structure, or by embedding them into the roof construction. They are permanently installed and do not need to be reassembled every time they are accessed.
Advantages over temporary systems: no assembly effort before each access, higher stability due to structural attachment, no ballasting necessary, and clear recognition of secured areas. Disadvantage: higher installation effort, roof penetration usually unavoidable, higher investment costs.
Permanent anchorage devices according to EN 17235
In addition to collective side protection, permanent single anchor points or cable fall arrest systems are also possible. These are aimed at individuals or small teams using PPE against falls from a height. The relevant standard since the revision is EN 17235 – it replaces the former EN 795 for fixed anchorage devices.
Permanent anchor points are particularly suitable for areas where a complete railing is not feasible – for example, at roof hatches, transitions, or in narrow technical areas.
Planning: What operators and planners must consider
Permanent systems must be considered already in the planning phase. Subsequent installation is possible, but more complex and expensive. DGUV 201-056 explicitly addresses planners and architects: buildings that are frequently accessed should already include suitable protective measures in the design.
For existing buildings: Anyone who regularly accesses their roof and does not yet have permanent fall protection should carry out a risk assessment and retrofit the system. In the event of damage, DGUV 201-056 will be used as a benchmark for the state of the art.
Inspection obligations for permanent systems
Permanent fall protection systems must be inspected regularly. DGUV 201-056 recommends an inspection at least every 24 months by a competent person – an earlier inspection is recommended in case of increased load or after special events (storm, snow load, mechanical impact). The inspection must be documented.
Temporary addition: Mobile anchor devices
Permanent systems cover the standard case. For special areas or temporary extensions of the secured area, mobile anchor devices are the practical addition. They can be positioned flexibly and used without roof penetration.

Frequently Asked Questions
Do I have to accept roof penetration?
For true permanent railings, generally yes. For parapet clamping systems or free-standing systems with ballasting, there are solutions without roof penetration – however, with higher maintenance efforts.
What does permanent fall protection cost?
This depends heavily on the roof area, the number of edges to be secured, and the chosen system. Individual planning is recommended before comparing costs.
Who is allowed to install permanent systems?
Installation must be carried out by qualified personnel familiar with the system requirements and relevant standards. The manufacturer specifies the required qualifications.
