How On-Roof Module Mounts Protect Roofs and Reliably Support Solar Systems
Professional installation of an on-roof module mount on a pitched tiled roof. The precision fit in place of the original roof tile is clearly visible.
Solar Energy Demands Secure Mounting
Solar energy, alongside wind and water, is one of the cornerstones of a sustainable energy supply. More and more roofs are becoming power plants — a visible symbol of the energy transition.
Yet installing a photovoltaic system means far more than attaching modules. It is an intervention in a roof structure that has functioned reliably for decades. Errors made here often only become apparent years later — by which point repair costs are high and the entire installation is frequently at risk.
A Precise, Non-Invasive Solution
Lehmann's on-roof module mounts offer an excellent solution. Developed specifically for installation on existing roofs, they ensure that roof tiles typically require no cutting or grinding whatsoever.
Rather than weakening sensitive materials, the mounts replace the original tiles with a precise fit — compatible with over 90 different roof tile models. The roof surface remains intact, providing a solid foundation for a long-lasting installation.
Stable Without Leverage
The bracket is fixed directly in the rafter zone using a reinforcement rail. It transfers the load vertically into the load-bearing roof structure, without creating any leverage on tiles or concrete roof stones.
This design makes the structure exceptionally resistant to shear forces, wind uplift, and snow loads. Every fixing can be calculated in accordance with standards and adapted to the relevant region.
Long-Lasting Surfaces from the Experts
All components are hot-dip galvanized and additionally coated with a polyester resin-based powder coating. This provides lasting protection against corrosion and ensures structural integrity over decades.
Variants for low-pitched bitumen and membrane roofs, together with matching cable penetrations, complete the range. Lehmann thus covers virtually every application — from residential properties to large commercial buildings.
The Benefits in Practice
- No cutting of roof tiles
- No risk of hairline cracks
- No leverage on the roof surface
- Exceptional load-bearing capacity
- Time savings during installation
Our experience shows: only when technology and craftsmanship work together with precision do solutions emerge that stand the test of time. At Lehmann, we develop on-roof module mounts with the ambition of protecting roofs while advancing the energy transition.
