Roof waterproofing in Geneva

Flat roof letting in water, membrane at the end of its life, recurring leaks? We waterproof and fully renovate your roof — cleanly and for the long term.

A flat roof that stays watertight

On a flat roof, water doesn't drain as quickly as on a pitched roof: the smallest weakness in the membrane eventually causes infiltration. We work on all types of roof terraces, whether accessible or not, to install reliable waterproofing suited to your substrate.

Our roof waterproofing services

  • Full renovation of flat roof waterproofing
  • Installation of bituminous or synthetic membranes (PVC, EPDM)
  • Liquid (resin) waterproofing for complex surfaces
  • Treatment of upstands, joints and detail points
  • Associated thermal insulation (warm / inverted roof)
  • Maintenance and periodic waterproofing checks

How we choose the right system

The right build-up depends on the substrate, the slope, how the roof is used and the existing insulation. We carry out an on-site diagnosis, then a clear quote stating the chosen solution and a firm price. Every project is covered by a written guarantee.
