Heat Reflective Roof Coatings and Paints

SolarEx offers water-based 100% acrylic coatings and solvent-free 100% silicone coatings. Acrylic formulations like SolarEx 300 and TropEx 310 deliver high solar reflectance, dirt pickup resistance, and flexibility over various substrates. Moisture-cure silicone options like SiliconEx 500 create a seamless hydrophobic barrier specifically engineered for flat roofs requiring permanent ponding water resistance and long-term weather durability.

These reflective coatings are compatible with a broad range of roofing substrates. Depending on the specific product formulation, compatible surfaces include metal, concrete and masonry, wood, asphalt shingles, built-up roofing (BUR), mineral cap sheets, single-ply membranes such as TPO and EPDM, spray-applied polyurethane foam (SPF), and existing elastomeric roof coatings.

Heat reflective cool roof coatings feature high solar reflectance, reflecting up to 90%+ of UV and infrared radiation away from the building surface. By minimizing solar heat absorption through the roof assembly, these coatings reduce indoor heat gain, decrease the workload on air conditioning equipment, and lower overall utility bills for commercial and residential facilities.

Yes, 100% silicone coatings such as SiliconEx 500 are specifically designed with hydrophobic properties that provide permanent ponding water resistance. Unlike water-based acrylics that can soften under standing water, moisture-cure silicone forms a seamless waterproof membrane that does not degrade, making it an ideal restoration solution for low-slope or flat roofs prone to ponding.

These roof coatings can be applied using standard commercial equipment including airless sprayers, rollers, or brushes. For airless spray application of acrylic products like SolarEx 300, a sprayer capable of 3,000 PSI or higher is recommended. Products should be applied to clean, properly prepared compatible surfaces according to manufacturer specifications to ensure proper adhesion and longevity.

Reflective coatings are primarily supplied in bright white to maximize solar reflectance. Additionally, select formulations like TropEx 310 are available in standard colors such as Gray and Tan, while SolarEx 300 offers custom color matching using a 1,020-color fan deck as well as major brand color collections to meet architectural preferences.
