Can Reflective Roof Coatings Really Reduce Heat? Absolutely! The science behind it is both simple and smart. Reflective roof coatings—often referred to as heat-reflective or cool roof paints—are specially formulated to minimize solar heat absorption and improve thermal insulation. Their unique composition allows them to reflect a significant portion of solar radiation, acting almost like a mirror for UV rays. Watch this short video for a quick explanation.
