Cool Roof Coat
Energy-Efficient Roof Protection That Lasts
Cool Roof Coat is a high-performance, water-based acrylic coating engineered to reduce heat transfer, extend roof life, and cut HVAC energy use by up to 50%. Developed with NanoTech's proprietary additive and high solids formulation (71%), this flexible membrane provides a durable, UV-resistant barrier that resists ponding water, cracking, and thermal degradation—even when dirty or weathered.
Unlike conventional reflective coatings, Cool Roof Coat actively rejects solar heat through a combination of low thermal conductivity and high emissivity. It restores aging commercial roofs without tear-off, qualifying buildings for long-term energy savings, tax incentives, and reduced carbon output.
