Why GE Enduris 3500?
GE invented silicone production technology in the 1930s and 1940s. The first roof was coated in 1967 and is still functioning. That proven lifespan of more than 40 years is unmatched.
Where traditional petroleum-based roof coverings need replacement after 10 to 15 years, GE Enduris 3500 takes a fundamentally different approach: an alkoxy silicone polymer that does not age, does not crack, and remains permanently elastic.



GE Enduris 3500 is airless-sprayed under pressure and can be applied directly over the existing roof covering. Nothing has to be removed or hauled away. The result is a seamless, vapor-permeable membrane with 542% elasticity that is 100% waterproof and fully UV-stable. The system is free of solvents, BPA, and toxic substances and is based on silica (quartz sand) rather than hydrocarbons.
The sustainability advantages go beyond the product itself. Its carbon footprint is many times lower than that of bitumen, EPDM, or PVC. At end of life, the material breaks down into nothing but sand and lime. And thanks to the layer-on-layer principle, the roof covering is infinitely renewable. No demolition, no waste.

GE Enduris 3500 is the only coating system that can be applied directly over bitumen, EPDM, PVC, TPO, concrete, and steel profile sheets. The existing roof covering does not have to be removed. After a Pre-Approval Warranty inspection with adhesion testing, we determine whether the roof is suitable and a GE Warranty File is compiled.
GE Enduris 3500 has a proven lifespan of more than 40 years. The first roof was coated in 1967 and is still intact. GE Momentive offers factory warranties of 15, 20, or 25 years — where the industry standard (VEBIDAK) maxes out at 10 years.
GE Enduris 3500 reflects 88% of sunlight (SRI: 111). Where a black roof gets 35–45°C hotter than the outside temperature on a sunny day, a Cool Roof only rises by 5–10°C. The result: an indoor temperature that is 3 to 6 degrees lower, which has a positive impact on air conditioning
GE Enduris 3500 is a 1K 100% alkoxy silicone polymer — not a blend with acrylates or other fillers. The product has been continuously developed by GE/Momentive since 1967 and applied worldwide on more than 10 million m². Cool Roof Coatings is the exclusive GE Silicones Distributor for the Netherlands and Denmark and the only officially certified installation partner.
GE Enduris is based on silica (SiO₂, quartz sand) — not fossil feedstocks. It contains no solvents, no BPA, no toxic substances, and no soot or sulfur fillers. At end of life, it breaks down into sand and lime. Thanks to the layer-on-layer system, full replacement is never needed: the roofing is circular and infinitely renewable.
