Repairs to Roof Waterproofing Membranes 

The consequences of a leaking roof are often extremely costly -and may involve extensive water damage to infrastructure below and sometimes to adjacent properties.

Overcoat Existing Membranes

Roof Membranes Deteriorate Due to Various Reasons

  • Cracks may develop due to an inflexible membrane that cannot cope with the normal thermal movement of a roof surface.
  • Waterproof membrane is not UV Stable and deteriorates with age.
  • Roof membrane uses joins, seams or overlaps that de-laminate and allow water to migrate under the membrane and track along the roof surface.

  • Conform to Roof Shape - ability to seal & waterproof around roof services & fixtures.
  • Critical for Roof Coatings  - commercial & industrial roofs often have complex shapes & contours that require liquid coatings that can seal vertically and horizontally.


  • Membranes with seams and/or joins often become areas of weakness for future water leaks.
  • Waterproofing installation using heat and/ or fumes have the potential to damage infrastructure, wiring and creates OH&S issues.
  • Equipment & methods need to be suitable for confined spaces, elevated surfaces and portable for roof repairs.
  • Roof repair may require structural knowledge & construction experience.
  • Repairs methods, waterproof products used need to be appropriate for each project.
