Sika's Commitment for Sustainable Roofs

When you think of the environment, what do you see? At Sika we see an energy smart roof that not only reduces environmental impact and minimizes waste, but delivers higher ROI (Return On Investment). Our roof keeps maintenance and utility costs low, by delivering proven performance, year after year, because when it comes to sustainability we aren’t just thinking about what our customers need to be successful today, but the value of our innovative roofing solutions will continue to deliver for decades to come. Sika, performance that pays, sustainability that is smart.


Sika supplies in addition environmental friendly portfolios for green roofs , solar reflective cool roofs and solar roofs. Sika has invested in state-of-the-art processing equipment that enables large scale recycling of post consumer vinyl roofs back into roofing products. These products include walkway pads, protection membranes and roofing and waterproofing membranes.

Specify Sika Roofing Systems Which Contribute Towards Your Green Building Certification

Sarnafil, Sikaplan and SikaRoof MTC roofing systems contribute to multiple points in most Green Building Certification systems. This is done by:

  • Replacing natural landscape removed in the construction process
  • Controlling storm-water runoff with a Sika green roof
  • Reducing the heat island effect with a highly reflective Sika roofing system
  • Using high performance thermal insulation
Evaluate the Sustainability of Your Whole Roofing System with Life Cycle Assessment

Life Cycle Assessment (LCA) is a standardized method to assess and compare the inputs, outputs and potential environmental impacts of products and services over their life cycle. It is also the basis on which Sika develops and evaluates the environmental performance of its solutions with facts.
The Sika LCA`s for standard roofing systems are available according to the ISO 14040 series and the Standard EN 15804.


The LCA model was reviewed by the leading independent research institute Swiss Federal Laboratories for Materials Science and Technology (EMPA).
Taylor made LCA can be calculated for specific projects, as Sika roofing system build-up may be adapted to the specific conditions of the project

Secure the Durability of Your Roof with Sika’s Performance for Decades

The durability of building materials is a key driver for sustainable building construction. Internal and external studies have documented the outstanding service life of Sarnafi l® and Sikaplan® roofing systems.
The British Board of Agrement (BBA) certifies Sarnafi l® G/S > = 1.5 mm membranes to have a life expectancy that is "in excess of 40 years"
Investing in durability means saving energy and resources
Investing in durability is a smart choice – it means saving maintenance and replacement costs

Let Sika Build Green Roofs for You

The addition of a green roof to an otherwise unused area of a building is beneficial for the surrounding environment. Initial loss of “green” space and its inherent natural processes like photosynthesis are restored, now just a few stories higher. But green roofs also have other benefits that you might not be aware of:

  • Storm-water retention
  • Reducing the urban heat island effect
  • Reducing energy consumption
  • Improving air quality
Save Energy with Sika Solar Reflective Roofs

The benefits of solar reflective materials and colours are well known and understood, especially in warm climates around the world. With urban density increasing, the heat island effect is also impacting on cities at an ever increasing rate. Sika roofing systems include highly reflective, white, polymeric membranes and liquid applied systems:

  • Solar Reflectance Index SRI of 111% and 110% respectively 
  • Reducing the heat island effect 
  • Reducing the cooling energy consumption requirements for buildings
Join Sika’s Recycling Programmes

Recycling is the smart choice – it saves energy and resources. Sarnafi l® and Sikaplan® roofing systems have been on the forefront of recycling since the 1960s.
Recycling of production waste: Sika has been recycling production waste and roll edge trimmings since the 1960’s.
Recycling of post-consumer waste (end-of-life): Sika actively participates in the end-of-life recycling program ROOFCOLLECT
Innovative products made from recycled materials: production waste and post-consumer membranes are recycled into new products, such as protection sheets and walkway pads.
