Also called high-albedo roof or white roof, a cool roof has the ability to reflect over 65% of the sun’s rays, compared to conventional roofs which repel less than 15%. Cool roofs are able to repel heat because the outermost layer contains special reflective material.

Cool Roofs Offer Many Long-term Benefits to Your Project
- Reduce the need for mechanical air conditioning and save energy costs
- Reduce urban heat island effect in cities and suburbs, minimizing thermal impact on the microclimate and on the local environment
- Minimize heat gain inside buildings, improving occupant comfort
- Enhance the durability and the appearance of roofs by significantly lowering material temperatures and extending the roof life
Sika Cool Roof Systems – What Makes a Good Product?
Our large product portfolio of waterproofing membranes for flat roofs includes suitable solutions for virtually any application.
Requirements | Are Sika Cool Roof Systems Available? |
---|---|
High initial Solar Reflectance Index (SRI) values | ✓ |
High reflectance value after exposure (slight reduction of reflectance during first years until constant color is reached) → The benefits of cool roofs (significantly reduced energy consumption) is maintained throughout the service life | ✓ |
Good cleaning properties allow regaining SRI values close to 100% of the initial value → Suitability of all technologies for the specific climate must be respected | ✓ |
LEED requirements for LEED Credit 5, Option 1 | ✓ |
LEED requirements for other LEED credit options | ✓ |
Single-ply membranes (FPO and PVC) | ✓ |
Liquid-applied membranes and coatings (several technologies) | ✓ |
Compatibility with the entire roof system, including accessories | ✓ |
Proven performance and reliability, high durability → Lower surface temperatures increase life expectancy | ✓ |
Environmental Product Declarations (EPD) available | ✓ |
