PROFINESS mounting profiles and connecting elements are installed in hundreds of single-family homes and apartment buildings every day, providing a reliable foundation for your transition to a carbon-neutral and, in the long term, electricity-cost-neutral household.

In our comprehensive guide, we show you how to easily and safely install your substructure on a tiled roof.
You will receive practical support in selecting and using the right components, including:

• Suitable roof hooks for different types of tiles and roof pitches,
• Optimal length of pan head screws for secure fastening,
• Suitable module and centre clamps for your individual design.

Our instructions guide you from the first step to the final assembly – ensuring that your PV system is installed on your roof in a stable, efficient and future-proof manner.

Substructures on trapezoidal sheet metal roofs – quick, easy and cost-effective

Substructures on trapezoidal sheet metal roofs can usually be installed quickly, easily and cost-effectively.
With many common trapezoidal sheet metal profiles, so-called short rails can be screwed from high rib to high rib. Alternatively, with transverse modules, it is possible to attach short pieces of rail directly to the high rib.

The following article explains what else you need to bear in mind, apart from screwing the bracket onto the sheet metal correctly.

Eternit or corrugated iron roofs often pose a particular challenge, as in many cases it is not possible to simply screw short rails from wave to wave.
In such cases, we therefore carefully examine the structure beneath the roof covering.

Similar to tiled roofs, the substructure is anchored to the load-bearing beams using so-called hanger bolts.
The following text explains what needs to be considered and what particular challenges await us when fastening to steel beams.

Your flat roof – your energy source!

Whether on garages, the flat roofs of detached houses or on a large scale on huge industrial buildings – installing solar modules on flat roofs is very much in vogue. But here too, it’s the details that count! The right angle in particular is crucial for maximum yields.

Depending on how you want to use your roof and which orientation you prefer, we offer perfectly tailored solutions: flat roof systems with south-facing or east-west orientation, or innovative roof-parallel systems – the right concept for every requirement.

Design your own flexible flat roof system – with mounting triangles at the angle you require. Or opt for our aerodynamic flat roof systems, which have been tested and certified in a wind tunnel.
Our experts will work with you to develop a tailor-made solution that is precisely tailored to your project.

Discover the advantages of our aerodynamic flat roof systems below and bring your energy future to the roof!

Of course, we also offer solutions for those who want to start from scratch. Whether it’s a balcony power plant on the railing, on the garden fence or on the house façade. We have also created assembly sets for such smaller solutions and collected many other ideas.

In rare cases, we receive feedback that stains are visible on our aluminium profiles.
