Leadership In Energy and Environmental Design
Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators with a framework for identifying and implementing measurable green building design, construction, operations and maintenance solutions.
LEED certification consists of a number of different rating systems that apply to many building types – commercial as well as residential – and measures how well a building performs across many sustainability metrics including: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.
With more than 60 years of experience providing long lasting, energy efficient roofing and waterproofing systems – combined with the knowledge gained from working on dozens of LEED certified buildings – Sika Roofing is uniquely qualified to assist you with your LEED project.
Sustainable Sites
| Site Development: Protect or Restore Habitat | Hydrotech® Garden Roof® Assemblies maximize the available habitat for local species and contribute to the possible 2 points. |

| Rainwater Management | During heavy rainfall, runoff from impervious surfaces such as pavements and rooftops can cause problems including sewer overflow and water pollution. Hydrotech® Blue Roofs can be designed to retain rainwater and discharge it to the sewer system at a slower rate to alleviate storm surges. Hydrotech® Garden Roof® Assemblies also can retain some rainwater. Sika® Drainage Mat is a prefabricated drainage composite that can be used to collect and convey excess water in areas such as plaza decks, split slabs, planters, and garden roofs. These solutions contribute up to 3 possible points. |
| Heat Island Reduction | Sarnafil® or Sikaplan® PVC Membranes, Sikalastic® Liquid-Applied Membranes, and Hydrotech® Ultimate Assembly® and Garden Roof® Assemblies qualify as highly reflective solutions or vegetated roofing which help to reduce the heat island effect and contribute to up to 2 points. |
| Places of Respite | Hydrotech® Garden Roof® Assemblies and Blue Roofs maximize green spaces and can help sites meet vegetated space goals, even in urban environments with limited site space. These systems contribute to the possible 1 point. |
| Direct Exterior Accss | Hydrotech® Garden Roof® Assemblies and Blue Roofs maximize outdoor spaces and can be adapted to provide hospital patients and employees with green spaces especially in urban environments. The systems contribute to the possible 1 point. |
Energy & Atmosphere
Sika's Solar Roof System can contribute to multiple points in LEED's Energy and Atmosphere.
| Minimize Energy Performance | Sika’s roof insulation products have enhanced thermal capabilities that reduce loading on HVAC systems due to outdoor air infiltration. This results in lower energy use and cost savings associated with building heating and cooling. Sarnafil® or Sikaplan® PVC membranes and Sikalastic® Liquid-Applied Membranes qualify as highly reflective solutions. Hydrotech® Ultimate Assembly® and Garden Roof® Assemblies provide insulating properties to roofing systems. All solutions increase energy efficiency. |
| Optimize Energy | Sika’s roof insulation products have enhanced thermal capabilities that reduce loading on HVAC systems due to outdoor air infiltration. This results in lower energy use and cost savings associated with building heating and cooling. Sarnafil® or Sikaplan® PVC membranes and Sikalastic® Liquid-Applied Membranes qualify as highly reflective solutions. Hydrotech® Ultimate Assembly® and Garden Roof® Assemblies provide insulating properties to roofing systems. All solutions reduce energy load of a building. These solutions contribute up to 20 possible points. |
| Renewable Energy Production | The Sika® SolaRoof System combines energy efficient roof solutions with photovoltaic panels to generate energy for the building’s use contributing towards a possible 3 points. |
Materials and Resources
Sika Roofing's Roof Recycling Program, EPD's and third party verifications can be used to obtain multiple points in LEED's Materials and Resources category.
| Building Product Disclosure and Optimization-Environmental Product Declarations | Several Sika products have Type III, product-specific EPDs. For a comprehensive list of all Sika® product EPDs, visit the Sika Corporation (USA) website. For American Hydrotech’s current EPDs, please visit the American Hydrotech® website.These solutions contribute to the possible 2 points. |
| Certified Multi-attribute Products and Materials | Sarnafil® G 410 and Sarnafil® S 327 membranes are certified Platinum under NSF/ANSI 347-2012: A Sustainability Assessment for Single Ply Roofing Membranes. The contributes towards 1 point. |
| Building Product Disclosure and Optimization-Sourcing of Raw Materials | 10-foot wide Sarnafil® and Sikaplan® PVC roofing membranes as well as a few other membrane products all contain an average of 10 percent recycled vinyl content from pre- and post-consumer sources. Hydrotech® MM6125® contains pre- and post-consumer recycled content with up to 40% post-consumer content. Sika’s polyester fleece reinforcement used in Sikalastic® RoofPro systems contains 98% recycled content. This contributes to a possible 2 points. |
| Building Product Disclosure and Optimization- Material Ingredients | Sarnafil® G 410 and Sarnafil® S 327 have third party verified Material Ingredient Reports (MIR). Monolithic Membrane 6125®, MM6125® Surface Conditioner, Flex Flash-F, and Hydroflex 30 have a Health Product Declaration (HPD) which is compliant with the Health Product Declaration Open Standard. This contributes to a possible 2 points. |
| Construction and Demolition Waste Management | Sika® Roofing offers an old roof recycling program for PVC membranes that has accepted and recycled more than 90,000,000 pounds of materials. Participating in this program reduces the project’s carbon footprint, reduces waste, saves customers money, and can contribute towards a possible 2 points. |
| PBT Source Reduction – Lead, Cadmium, and Copper | Several Sika® Roofing products are lead and cadmium free. Please contact us for more information on this credit. |
Environmental Quality
Sika Roofing's Low or No VOC emitting roof membrane adhesives and stone wool insulation can be used to obtain multiple points in LEED's Environmental Quality Category.
| Minimum Acoustic Performance | Sarnafil® and Sikaplan® PVC Membranes, and Sikalastic Liquid-Applied Membanes both with insulation or Hydrotech® Garden Roof® Assemblies offer roofing solutions that help dampen outdoor noises and enhance acoustic performance. |
| Low-Emitting Materials | Several Sika® Roofing products have undergone volatile organic compound (VOC) emissions testing. This testing is done in accordance with the California Department of Public Health (CPHD) Method v1.2-2017. This can contribute towards up to 3 points. |
| Thermal Comfort | Sarnatherm® Roof Insulation products provide superior thermal performance. Unlike other insulating solutions, Polyiso is compatible with a wide variety of roofing systems including both single-ply PVC and liquid-applied membranes (LAM). The result is a versatile thermal roofing system that provides an enhanced building envelope, leading to a comfortable indoor environment with reduced heating and cooling loads. This contributes to 1 point. |
