The modular, certified roof maintenance concept.

Flat roofs are subjected to high loads and stresses every day: Thermal influences such as heat, UV radiation and cold as well as moisture, resulting from rain, standing water and building moisture, have an effect on the waterproofing. Then there is also the mechanical stress on the supporting structure caused by wind, ice and hail, work on superstructures and foot traffic on the roof surfaces. These influences, as well as possible technical processing deficiencies or material fatigue, inevitably lead to leaks in the roof cladding over time.

The Roof Protection Plan (RPP)

The modular, certified roof maintenance concept. In addition to the basic services of quality roof maintenance, the RPP includes the following modules:

  • Inventories
  • Cataloguing
  • Surveys using the latest technology
  • Leak tests on the flat roof
  • Safety checks of the roof surfaces
  • Innovative flat roof monitoring
