Leak detection in roofs and preventive checks

Leaks in roofs are usually impossible to detect with the naked eye. Our experts and their specialised material can detect even the smallest leaks – for roofs with or without ballast.

Our expertise

Finding roof leaks quickly and accurately

Even an experienced roofer will sometimes have trouble finding the cause of a leak. Water may have travelled quite a distance – artificial flooding is not guaranteed to find the leak, because many defects are located in upright structures and marginal integrity structures. Water does not always enter when it rains, but after a long period of time or only under certain circumstances.

We can quickly and accurately find invisible leaks in your roof. Thanks to our state-of-the-art equipment and the extensive knowledge and experience of our staff, we can significantly reduce the costs and inconvenience associated with a leak in your roof.

Roofs without ballast

Roofs without ballast: flat or pitched roofs

A visual inspection using a ladder or elevated platform is sufficient with a pitched roof – paying extra attention to critical details like gutter areas, skylights, dormer windows and chimney joints. For flat roofs, Cibor uses advanced equipment to very precisely find damage or faults – usually without demolition work.

Pitched roofs

  • Visual inspection using a ladder or elevated platform
  • Extra attention to gutter areas, skylights, dormer windows and chimney joints
  • Specific water tests using specialised equipment

Flat roofs

  • Very precise fault-finding with advanced equipment
  • Water tests: simulating torrential rain using a rain frame, direct cavity drainage load
  • Defective joints on upright structures and thresholds – usually without demolition work

Damp screens and independent reporting

  • Drawing water off the damp screen using specialised equipment
  • Cibor acts as an independent and impartial loss adjuster
  • Objective reporting – a well-founded basis to apportion responsibility

Questions?

Do you have a leak in your roof?

Roofs with ballast

Roofs with ballast: green roofs, roof parking, roof terraces

We can often inspect roofs with ballast, like green roofs or roof terraces, without removing the actual roofing. Our experts only remove the ballast in certain places, which means the impact remains limited. Cibor implements a number of techniques that allow leaks to be found without (or only minimum) digging and demolition work.

Green roofs

Finding a leak without breaking up your whole green roof – ballast removed only locally.

Roof car parks

Locating leaks in roof car parks with minimum inconvenience for users.

Roof terraces

Finding sealing faults on roof terraces without destructive investigation.

Basement sealing

Checking the water-tightness of basement sealing and underground structures.

Solar panels

Preventive checks of roofs featuring solar panels.

Vulnerable spaces

Preventive checks of roofs above data centres, laboratories and museums.

Preventive checks

Preventive checks for water seals on flat roofs

We preventively check flat roofs sealed with PVC, EPDM or other roofing, using equipment that best suits the roof structure. Preventive checks are carried out during the construction phase, before water seals are covered with ballast, paved surfaces or green roofs – detecting potential shortcomings before damage occurs. A partly detached seam joint will not immediately cause a leak: over time (ageing) and under ambient factors (heat, frost, dirt, shrinkage and expansion) it may become fully detached.

What happens if our experts find a leak? We immediately inform the concerned contractor, who can rectify the issue – a follow-up check after repairs is appropriate. A preventive roof check means peace of mind for contractors and future owners: they know their roof has been checked by a completely neutral party.

Preventive checks on water seals are useful for:

  • gravel roofs
  • roof terraces
  • green roofs
  • roofs featuring paved surfaces/clinkers/roof garden
  • basement sealing
  • roofs featuring solar panels
  • roof car parks
  • roofs with vulnerable underlying spaces, such as data centres, laboratories, museums, etc.
