BEMO Standing Seam Roof

A Modern, Flexible, and Sustainable Solution for Any Building Geometry

Few roofing systems can meet as many different requirements as a multi-skin metal roof system with standing seam profiles. Whether you’re working on a new construction or a renovation, BEMO’s standing seam roof meets the high demands of modern architecture.

The key to the standing seam roof lies in its innovative design.  The profiles are self-supporting and are installed without penetrating the surface. Thanks to the variable profile lengths of the standing seam covering, overlaps are eliminated, and permanently welded connections provide continuous sealing. The BEMO system allows for flexible adaptation to virtually any building shape.

Standing Seam Roof for Highest Structural Demands

High load-bearing capacity and excellent static values characterize the BEMO standing seam roof

If you’re seeking a roof that not only stands out visually but also meets the highest structural standards, the BEMO standing seam roof is the ideal solution. Our standing seam profiles combine exceptional load-bearing capacity with superior static properties, offering maximum security in metal roofing. This makes them perfect for large, shallow-pitched roofs and innovative custom shapes.

Thanks to BEMO’s specialized profiles, adjustment to nearly any roof shape and pitch is possible without penetrating the roof structure. The profiles are installed by simply folding them onto specialized standing seam halters, resulting in a weatherproof and aesthetically pleasing solution. Whether you are planning a monopitch roof for a small house or a complex roofing structure for a large industrial building, the flexible design of the standing seam roof allows for unlimited creativity. The visual design options for standing seam roofs, including the profile shape, metal, surface finish, and color selection, are virtually limitless.

The three proven profile variants can be selected as standing seam roofing for all materials:

N 50 – with 50 mm seam height and variable profile widths. This profile has a delicate and aesthetic appearance and is often used for smaller roof areas such as mono-pitch roofs and residential buildings, as well as in industrial roofing without high snow loads.

N 65 – with 65 mm seam height and variable profile widths. This profile is ideal for flat sloping roofs due to the high seam. It is further distinguished by its very good load-bearing capacity and therefore good static values.

VF 65 – with 65 mm seam height and variable profile widths. When used on rigid insulation and timber boarding, the profile covers the entire surface. A special moulding accommodates the geometry of the bracket foot without imprinting.

BEMO-MONRO® – A System for Special Standing Seam Roofs

For unique building shapes, flexible and precise

The patented BEMO-MONRO® metal roof system stands for flexibility and adaptability of standing seam roofs to nearly any construction form. Each profile of a free-form object is often a one-of-a-kind piece. Using precise 3D measurement data, the metal sheets are formed with millimeter accuracy for the designated space on the building.

For the standing seam roof covering, the MONRO® system is typically used in combination with a three-dimensional adjustable metal roof substructure. This allows any irregularities in the supporting structure to be easily and quickly compensated for with the metal roof construction for the standing seam roof. BEMO’s 3D planning prepares the standing seam system ready for assembly – usually based on a 3D scan of the supporting structure.

For larger circular and conical buildings, special conical profiles are ideal . With a minimum width of 100 mm and a maximum coverage width of 800 mm, nearly any roofing requirement can be met. The standing seam sheets are precisely shaped in one step, eliminating the need for complicated cutting on site and making the standing seam system easier to use.

All BEMO special profiles can also be supplied in a curved form and in all materials – including sustainable options.

A metal roof curved to the smallest radii for flowing building forms

Precise Fit with Maximum Functionality and Safety with BEMO Metal Roofing Systems

A roof that is not only functional but also allows for impressive, flowing building shapes – this is no problem for BEMO. Our custom-fit and curved standing seam profiles are formed in a special production step, often directly on-site, into their final shape. This not only optimizes freight costs but also ensures a perfect fit for your construction project.

The curvature can be concave, convex, or concave-convex – standing seam profiles can be curved to even the smallest radii. Depending on the selected material and profile, we achieve minimum radii of less than 800 mm.

All BEMO standing seam profiles are suitable for subsequent curving without compromising functionality. To ensure precise and tolerance-adjusting assembly, we recommend using BEMO substructure systems like BEMO-DOME or BEMO-FLEX. A 3D scan of the building’s existing structure is also recommended for the standing seam roof, as well as utilizing BEMO’s 3D execution planning.

Let the sun in and make your roof transparent with monoSKY®

Metal Roofing System with Transparent Layer and Freeform Design

With the innovative monoSKY® system, you can transform your roof into an impressive light source. This unique system combines the durability of perforated standing seam profiles with the elegance of a transparent layer, offering you unprecedented design possibilities.

In sunlight, the monoSKY® roof system creates a pleasant dappled shadow thanks to its variable perforation pattern, while filtering harmful UV rays. At night, your building covered with monoSKY® softly glows outward and creates fascinating light effects that can be individually designed by the color choice of the light beneath the roof. Additionally, the semi-transparent construction reliably protects against wind and weather.

The roof system is mounted as a proven standing seam roof on halters. The transparent layer is inserted into the standing seam profiles from above and secured with a special mounting rail without penetration during roof installation. This allows you to design your standing seam roof to be transparent and cleverly conceal the installation – suitable for any architectural design.

The entire structure is permeable to a light spectrum with wavelengths between 435 nm and 660 nm, which are necessary for plant growth.
