Refurbishment of Bitumen Roofs

Systems: Refurbishment of Existing Bitumen Roofs

Mechanically Fastened Systems with Sarnafil / Sikaplan

  • Mechanically fastened roofs are the most cost efficient systems
  • Sarnafil T polyolefin membranes are fully resistant to bitumen and can be applied directly on to the old bitumen waterproofing
  • The fastest installation speed is achieved with mechanical fastening
  • Sarnafil / Sikaplan  membranes for mechanical fastening have special polyester reinforcement, enabling high wind load resistance
  • Installation is almost not weather dependent

Adhered Systems with Sikaplan / Sarnafil

Sikaplan / Sarnafil adhered roofing systems are designed specifically for roof refurbishment works, making them the No. 1 choice for the re-roofing of many bituminous roofs.

  • Bitumen compatible membranes
  • Membrane and insulation adhesives with excellent adhesion direct to bitumen
  • No penetrations of the existing roof build up are required
  • Very low noise emissions during installation
  • Easy application on simple and complex roof shapes
  • High aesthetic appearance and visual improvement
  • Many design possibilities with coloured membranes and profiles

Liquid Applied Membrane Systems with Sikalastic

Liquid applied membrane systems using our unique SikaRoof MTC technology can  provide many advantages such as:

  • Seamless waterproofing with full bond to the substrate
  • Installation is possible directly on the old bitumen without special priming
  • The new waterproofing layer is moisture and rain resistant just 10 minutes after application
  • 1-C products with the ideal viscosity for roofing applications (no need for additional thinners or hardeners etc.)
  • Easy installation with brushes or rollers, even over complex shapes and forms
  • High tensile strength and elasticity
  • Cold applied waterproofing – no flame, no heat
  • Long shelf life products
