White Solar Reflective Paints and Coatings for Asphalt Roofs

The ideal coating depends on substrate conditions and roof slope. For low-slope or flat roofs with ponding water issues, SiliconEx 500 silicone coating provides permanent ponding water resistance and reflects up to 88% of solar radiation. For sloped roofs, asphalt shingles, and mineral cap sheets, water-based elastomeric acrylics like SolarEx 300 and TropEx 310 offer high reflectivity and crack-bridging flexibility.

Coating longevity depends on the chemistry, system thickness, and proper installation. SolarEx 300 acrylic emulsion coating lasts 10 to 15 years when properly applied to compatible substrates. SiliconEx 500 silicone roof systems provide long-term resistance to weathering and ponding water, offering manufacturer material warranty options for up to 20 years based on the chosen system specification.

Acrylic coatings like TropEx 310 and SolarEx 300 are water-based, low-VOC formulations known for strong tensile strength, dirt pickup resistance, and easy water cleanup. Silicone coatings like SiliconEx 500 are solvent-free, moisture-curing membranes engineered specifically to withstand continuous ponding water without softening. Both chemistries provide high solar reflectivity to reduce surface temperatures and building cooling demands.

SolarEx coatings are engineered for versatile contractor application. They can be applied using a commercial airless sprayer rated at 3,000 PSI or higher, as well as heavy-nap rollers or brushes. Substrates must be clean, structurally sound, and dry before application. Depending on system specifications, coatings can be applied over existing elastomeric undercoats like ElastEx 200 or SealEx 100.

Yes, select formulations offer custom color matching alongside standard bright white finishes. TropEx 310 is available in white, gray, tan, and custom colors. SolarEx 300 can be matched to a 1,020-color fan deck as well as major brand color collections, allowing facility managers to achieve reflective heat reduction while meeting specific aesthetic requirements.

SolarEx roof coatings are available in multiple packaging sizes to support jobs of any scale. Options include 1-gallon containers, 4-gallon and 5-gallon pails, 55-gallon drums, and full bulk pallets containing 36 pails (180 gallons). Products are manufactured in Berkeley, California, and include free shipping options within the United States for qualified contractor and distributor orders.
