Naked roof

The black rubber seal is visible as the last layer, hence the name: naked roof. The water-sealing is fixed in place with the mechanical fixings Contec.fix or Contec.fix SFS isoweld®. We plan the positioning of these mechanical fixings for you according to the local wind conditions.


  • Easy to look after
  • Lightweight construction (static)
  • No roof penetration
  • Quick to install

Roof construction Rubber naked roof

Optional: Contec.watt - Photovoltaic

Intelligent technology, high energy efficiency, safety, performance guarantees and a long service life. That is what you can expect this from our tested photovoltaic systems.

Contec.proof – Rubber seal

A safe and elegant solution. Our long-lasting sealing material Contec.proof is UV-resistant, root-resistant, and does not contain any herbicides or pesticides. The EPDM rubber is welded together without glue and solvent and retains its elasticity for decades. Prefabricated and customized water-sealings for roofs and bodies of water in any form.

Contec.fix - Mechanical fixing

Contec.fix is a penetration-free mechanical fixing, developed in several variants to ensure its simple yet precise application in different areas.

Contec.therm - Thermal insulations

Our thermal insulations have proved their worth in technical terms and they can be recycled. We use one of our four types of Contec.therm depending on the nature of the roof.

Contec.vap – Vapour barrier

To reduce the diffusion of vapour on flat roofs. Contec.vap is available in two variants. Contec-vap bitumen is also used as an emergency roof during the construction period.
