Roof scaffolding, catch scaffold, protective scaffold – they almost always mean the same thing: the fall protection below the eaves. We plan, supply and erect it in compliance with the standards for roofers, carpenters and solar installers in the Cologne/Bonn region.
From enquiry to dismantling, everything comes from a single source: planning, material, erection and inspection are all provided by Gerüstbau Müller. Your roofer can start on time without you having to coordinate two trades.
Send us the roof area, eaves height and roof pitch, or give us a call. You will receive a reply as quickly as possible.
We look at the roof, plan the erection based on the roof geometry and the applicable standards, and submit a binding quote.
Trained scaffolders erect the scaffold in accordance with DIN EN 12811 and DIN 4420-1. For a detached house this usually takes between half a working day and a full working day.
Inspection by a competent person including an inspection report in accordance with TRBS 2121 – and professional dismantling once the roof work is complete.
The legal basis is clear: as soon as work is carried out on roofs with a pitch of more than 22.5° and the fall height from the eaves exceeds 2.00 m, roof safety scaffolding is mandatory under TRBS 2121-1 and DGUV Regulation 38.
The minimum width of the catch deck is 0.60 m. In short: anyone who wants – and is obliged – to protect roofers, carpenters or solar installers at work cannot do without professionally erected roof safety scaffolding. On flatter roofs, a side protection guardrail is often sufficient; we clarify in advance which solution suits your roof.
“Roof scaffolding” is the umbrella term most building owners use. Technically, it is almost always roof safety scaffolding: a special protective device mounted at the side of the top scaffold deck directly below the eaves. It performs two tasks at once – it catches people who fall and prevents tools, roof tiles or building materials from dropping uncontrolled to the ground.
A catch scaffold is the general term for any catch level below the workplace – on a roof it is called roof safety scaffolding. Unlike conventional facade scaffolding, which is primarily a working platform, roof safety scaffolding is purely a protective device – and on pitched roofs it is generally required by law.
For a comparison of all systems, see our guide Scaffolding types at a glance.

Whenever a roof covering is renewed – whether tiles, slate or bitumen membranes – roof safety scaffolding is the fall protection of choice. It creates a secure catch level directly below the working area.
The PV boom of recent years has made roof safety scaffolding even more important. On pitched roofs with a pitch of more than 20°, the German Occupational Safety and Health Act (ArbSchG) requires active fall protection – roof safety scaffolding with a safety screen in accordance with DIN EN 13374 is the standard-compliant solution here. Find out more on our page PV scaffolding.
Work on Velux windows, dormers or roof hatches requires precise work on the roof surface. Roof safety scaffolding reliably protects the tradespeople – even when only short sections of work are involved.
From chimney repairs to carpentry work: wherever tradespeople work on pitched roof surfaces, roof safety scaffolding protects life and limb – while meeting all the legal requirements of the German Ordinance on Industrial Safety and Health (BetrSichV).

From planning to acceptance: Gerüstbau Müller takes care of the entire process for you. Based on your roof geometry and the applicable standards, we draw up a tailored erection plan, deliver all scaffolding components to the site on schedule and erect the roof safety scaffolding in accordance with DIN EN 12811 and DIN 4420-1.
We are a member of the German Scaffolding Guild and work exclusively with tested system scaffolding from well-known manufacturers – we use Layher Allround and Rux Super. You will find an overview of all scaffolding types and areas of application on our services page.
A large share of our roof safety scaffolding is put up for other trades. If you run a roofing, carpentry or solar business and need scaffolding regularly, that is everyday work for us: we agree the date directly with your site management, hand over with an inspection report and dismantle as soon as you are finished.
Our own crews and our own material mean that we do not depend on whether a subcontractor has time. For urgent projects in the Cologne/Bonn region, we arrange delivery dates flexibly.
Every scaffold is inspected before release and handed over with an inspection report in accordance with TRBS 2121. You receive the documents you need for your own records and for the employers’ liability insurance association (Berufsgenossenschaft).
The costs depend on the size of the building, the roof geometry and the rental period. After a short site visit, Gerüstbau Müller will prepare a binding quote for you (lump sum or by measurement, depending on the building) – transparent, with no hidden costs. Invoicing follows VOB (German construction contract rules)/ATV DIN 18451:2023, i.e. erection and dismantling as a contracted service and the rental period on a weekly basis. For existing buildings such as a detached house, we can also agree a lump-sum price on request; for new builds we always invoice according to VOB.
The quickest guide price comes from our online scaffolding calculator – in around 2 minutes, free of charge and without obligation. You will find a detailed overview with price ranges on the page Scaffolding costs.
Under TRBS 2121-1, roof safety scaffolding is mandatory if the roof pitch is more than 22.5° and the fall height from the eaves is more than 2.00 m. On flatter roofs, a side protection guardrail is often sufficient.
Catch scaffold is the general term for any catch level below the workplace. Roof safety scaffolding is its special form on a pitched roof: it is erected directly below the eaves, the height difference between eaves and scaffold deck may not exceed 1.50 m, and the catch deck must be at least 0.60 m wide. Colloquially it is also referred to as “roof scaffolding” or “roof protection scaffolding”.
The costs depend on the size of the building, the roof geometry and the rental period. After a short site visit, Gerüstbau Müller will prepare a binding quote for you (lump sum or by measurement, depending on the building) – transparent, with no hidden costs. The quickest guide price comes from our online scaffolding calculator – in about 2 minutes, free and non-binding.
Erection and dismantling must be carried out by qualified persons who are able to draw up and implement a standard-compliant erection plan. After completion, an inspection by a competent person and the issue of an inspection report in accordance with TRBS 2121 are mandatory. As a specialist business with over 90 years of experience, we fully meet these requirements.
Depending on the size of the building and the roof shape, erecting roof safety scaffolding on a detached house usually takes between half a working day and a full working day. For apartment buildings or complex roof geometries, we plan the exact time required together with you.
Yes. Correctly dimensioned roof safety scaffolding with a safety screen and catch net not only catches people who fall, but also prevents roof tiles, tools or building materials from falling onto the pavement or adjacent areas – thereby also protecting uninvolved third parties.
