Standing seam roof – flexible metal roof systems with standing seam

A standing seam roof is the answer to the complex requirements of modern architecture. As an industrial metal roof system, it is characterized by linear profile panels that are connected to each other by protruding edges – the standing seams. The standing seam sheet metal roof shows its strengths especially when it comes to demanding geometries, large roof areas and architectural free-forms: It offers a perfect symbiosis of technical safety, extreme durability and clean, aesthetic lines.

The decision for a standing seam roofing from BEMO is a decision for system safety. Our solutions are designed to combine engineering with maximum design freedom.

Standing seam roofing for high building physics requirements

Why is this system suitable for high requirements? Because it doesn’t compromise. A BEMO standing seam roof convinces with excellent static values and an enormous load-bearing capacity, even with extreme wind loads. Thanks to the special standing seam technology, the system is predestined for flat-pitched roofs as well as for special shapes. Weatherproofing is guaranteed even in extreme weather conditions thanks to the force-fit interlocking, while the systemic structure of the standing seam covering provides optimum values in terms of sound and thermal insulation.

Mounting principle of the standing seam roof – interlocking without roof penetration

The heart of the safety of the standing seam roof is the assembly principle: the profiles are fixed on special holders and then interlocked by machine. This process takes place completely without penetrating the roof covering. The added value for planners and builders: a permanently tight, durable design and a clean, undisturbed appearance that remains free of visible screw connections.

Construction of a standing seam roof – substrates and details

The planning of a standing seam roof is project-specific. Building physics requirements such as heat and moisture insulation, airtightness and compliance with energy efficiency and fire protection specifications in accordance with applicable standards and guidelines are decisive. Depending on the requirements, different variants are available.

Standing seam profiles for roofing

Our profile variants follow a clear selection logic: While discreet seam heights create a fine structure, profiles with high web heights offer maximum safety with large volumes of water and very shallow slopes. Each standing seam roof covering can be chosen in such a way that it either rests on insulation or wooden formwork over the entire surface or acts as a self-supporting shell.

N 50 – with 50 mm seam height and variable profile widths. The standing seam profile has a discreet and aesthetic effect on standing seam roofing and is often used for smaller roof areas such as monopitch roofs and residential buildings as well as in industrial roofs without high snow loads.

N 65 – with 65 mm seam height and variable profile widths. The standing seam profile is particularly suitable for gently sloping roofs due to the high seam. It is also characterized by a very good load-bearing capacity and therefore good static values for the standing seam covering.

N65 Stehfalzprofil, hohe Steghöhe für flach geneigte Dächer und hohe Tragfähigkeit

VF 65 – with 65 mm seam height and variable profile widths. For use on non-slip insulation and wooden formwork, the standing seam profile lies over the entire surface. A special shape accommodates the geometry of the holder foot without leaving any marks.

Materials and surfaces of standing seam roofing

The choice of material determines not only the appearance, but also the life cycle costs and the ecological balance of a building. BEMO offers a range of materials that combine the highest corrosion resistance with individual aesthetics.

Aluminium: The preferred standard for the modern standing seam roof. Aluminium is extremely light, absolutely rust-proof and 100% recyclable. Especially near the coast or industrial areas, it offers unsurpassed durability.

Steel: An economical solution for large-scale industrial projects where high spans and static strength are paramount. With high-quality galvanizing and coatings, we also achieve excellent corrosion protection here.

Zinc, copper and stainless steel: These precious metals are often chosen for representative architecture. Over time, they form a characteristic patina that makes the standing seam roof appear alive and minimizes maintenance.

BEMO FLON & BEMO COLORS: Our surface finishes offer unlimited color possibilities. From ultra-matte finishes that minimize reflections to high-end PVDF-based coatings for maximum UV resistance and color fidelity for decades to come.

Special shapes in standing seam: straight, conical and curved to free-form

The architectural freedom in standing seam roofing knows hardly any bounds. Whether straight sheets for clear structures, conical profiles for round building shapes or convex, concave or concave-convex curves for curved roof landscapes – the BEMO standing seam system adapts. Even the smallest radii (<800mm) can be realized, which makes the standing seam the preferred tool for creative building designs.

All BEMO standing seam profile variants are also suitable for subsequent curving without losing functional reliability. To ensure precise and tolerance-compensating installation, we recommend the use of our standing seam roof substructures BEMO-DOME or BEMO-FLEX. A 3D measurement of the building structure in its current condition is just as recommended for standing seam roofing as the use of BEMO implementation planning in 2D or 3D.

BEMO-MONRO Freiformlösung für besondere BEMO-MONRO free-form solution for special building geometries

With the BEMO-MONRO system, we make the impossible achievable. Using state-of-the-art 3D measurement and digital 3D planning, we manufacture each standing seam panel as a unique specimen to fit complex free-form objects. Unevenness is compensated for by our three-dimensionally adjustable substructures, so that even spectacular designs can be executed with the highest precision.

For larger circular structures and conical buildings, conical, profiled special profiles with flexible profile widths are used. With a minimum width of 100 mm and a maximum of 800 mm, it is possible to meet almost any roof covering requirement. For this purpose, the standing seam panels are precisely shaped in a single step. This saves time-consuming cutting of the project and makes it easier to use the standing seam system.

We plan your standing seam roof to match your design!

Production and installation of standing seam roofs

The process is trimmed for efficiency: After precise plant planning, production takes place – often directly on site with mobile roll forming systems. The standing seam profile assembly is carried out by clipping the profiles onto the holders, followed by the mechanical sealing of the folds. This guarantees fast construction progress and the highest quality of execution.

Brackets and substructures for standing seam roofs

The substructure is the invisible backbone. BEMO holders safely absorb wind loads and enable the thermal expansion of the profiles. Whether for new construction or renovation during ongoing operation – we offer the right holder system for every substrate to minimise thermal bridges and optimise statics.

Standing seam roof costs: what factors affect the price

There are no flat-rate prices, as each system is calculated individually. Thus, the costs for a standing seam roof are very variable. The main cost drivers are:

  1. Roof geometry: Simple monopitch roofs vs. complex freeforms.
  2. Material & Coating: Choice of metal, thickness and finish.
  3. Substructure & Insulation: Requirements for energy efficiency.
  4. Logistics: Construction site production vs. delivery.

FAQ Standing seam roof

Do you have any questions about BEMO standing seam roofs made of aluminium or our metal roof systems? Our experts will be happy to assist you personally. You can also find many answers to frequently asked questions in our FAQ – so you can quickly get information about planning, materials and installation.

How much does a standing seam roof cost?

The cost of the standing seam roof depends heavily on the selected material quality, the complexity of the geometry and the insulation structure. A precise calculation is always carried out on a project-specific basis, taking into account the installation conditions.

What is the minimum roof pitch for a standing seam roof?

The BEMO standing seam system has been approved and tested by the building authorities and can be used from a minimum roof pitch of > 1.5°. This makes it an ideal solution for large, gently sloping roof surfaces.

What is a standing seam roof and how does it differ from other roofing systems?

It consists of metal profiles that are joined by folding without penetration. In contrast to through-fixed systems, it offers a higher weathertightness and can better compensate for thermal changes in length.

How is a standing seam roof attached?

The basis for the assembly of the standing seam panels is formed by special holders, which are available in different heights and lengths. After exact calibration, the brackets are screwed to the substructure. The profile panels are placed over these holders and connected by folding without penetrating the sheet metal itself.

What materials are best for standing seam roofs?

Aluminum is the standard due to its corrosion resistance and lightness. Steel, zinc or copper are also used for specific architectural requirements. Standing seam roofs made of aluminium are 100% recyclable. In addition, up to 75% of post-consumer recycled content aluminium is used for standing seam.

How long does a standing seam roof last?

With professional planning and execution, especially when using aluminium, a service life of over 50 years is common for the standing seam roof. It is considered one of the most durable roof systems ever. Even 70 years and more are no problem.

Can a standing seam roof be repaired?

Yes, individual panels can be replaced or professionally repaired by specialist companies in the event of damage without having to replace the entire roof.

Can a photovoltaic system be mounted on a standing seam roof?

Yes, the BEMO standing seam roof is ideal for the installation of photovoltaic (PV) systems. The PV modules are attached to special mounting rails that are attached directly to the standing seams – without penetrating the metal surface. This keeps the roof 100% tight, the statics remain unchanged and the risk of leaks is eliminated.
