Waste Minimization

Sika’s Roof Recycling Program

Waste reduction starts with durable products that stand the test of time. Sika Sarnafil membranes continue to perform after decades of use in a wide range of climates. When a roof must be replaced, our post-consumer recycling program recycles millions of square feet of used membrane yearly, reducing the burden on landfills.

We also reduce waste at every step of the product life cycle, converting more than 98% of vinyl raw materials from manufacturing and installation into new roofing and waterproofing membranes.

What about the disposal of old vinyl roofs at the end of their life cycle?


Post-consumer recycling, the recycling of roof membranes at the end of their useful life, is an opportunity to divert construction debris from the waste stream. The technology exists to recycle the material, but historically the lack of a need in the market has prevented the establishment of a viable infrastructure to allow recycling. The sustainability movement, along with the advent of landfill restrictions on construction waste in cities such as Chicago and Boston and the increase in waste disposal fees, has begun to create the conditions to make recycling old roofs a reality.

Target is very proactive about their roof assessment management and replacement even before the roof system fails. This allows them to resuse the insulation and roof cover boards ultimately increasing benefits. Learn about Target's sustainable roofing program.

The recycling of vinyl roofs starts with the removal of the old membrane from the facility. The membrane is then packaged, consolidated and shipped to a facility where it is processed into a form that can be reintroduced into the new product manufacturing stream. Vinyl is an excellent candidate for recycling because the old roofing material is easily introduced into the raw material base for the manufacturing of new roofing membranes and accessories.

Sika roofing 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.
