The short answer is, yes! White roof coatings provide the greatest reflectivity values available; however, that is not to say that other colors are not able to provide you with ideal reflectivity.
Highly reflective roof coatings are full of UV blocking pigments that provide your roof with protection against premature degradation caused by the sun’s heat. The greater amount of reflectivity the coating can provide, the longer your rooftop will survive. The added protection against the sun’s harsh elements can lower roof maintenance costs, lower energy consumption, extend the life of roof top mounted equipment and easily extend the roof’s lifespan. While roof coatings come in a large range of colors, choosing the whitest and brightest coating will provide you with the greatest reflectivity and protection to your roof.
National Coatings has four standard roof coating colors – white, sand, light gray and dark gray (we can also custom color match most any color necessary to meet your needs); however, of these four standard colors, white is our most popular as it provides our customers with the greatest reflectivity benefits. If you take a look at our roof coatings that are tested and rated by the Cool Roof Rating Council (CRRC), you will see our AcryShield A510 has an initial solar reflectance of 0.84 in white and 0.72 in sand. This is true with any of the other coatings that come in multiple colors; the white roof coating is always the most reflective.
Another factor to consider aside from color is, dirt pick-up resistance. Dirt pickup resistance is defined as having the ability to maintain it’s white color and appearance even after the roof has come in contact with dirt, dust, and other outside environmental conditions that could darken the surface. Long-term success of the coating you ultimately choose for your roof will greatly influence the cost savings and benefits you will gain. The CRRC is a great resource, as it not only provides initial testing but also 3-year, aged testing to determine the long-term reflective capabilities of the coating.
National Coatings’ products are engineered to achieve success in regards to high reflectivity capabilities. The AcryShield roof coating line is packed with more UV blocking pigments, is richer in performance ingredients, contains excellent dirt pickup resistance and provides some of the highest reflective roof coatings available to the roofing industry. The AcryShield Ultra High Reflectance A590 coating, for instance, has an initial solar reflectance of 0.92 and 3-year, aged solar reflectance of 0.87 - the aged, 3-year result is higher than most roof coatings can provide initially.

Reflective roof paint is actually not paint. The proper terminology is “reflective roof coating”. While roof coatings resemble paint, they are much more durable and the thickness and strength is unmatched to what paint is capable of.
The great thing about installing a roof coating system to your building is its ability to adhere to virtually any roofing substrate. White roof coatings can adhere to newly constructed roofs, aged and deteriorating roofs, and roofs that are in-between but are lacking reflectivity and UV protection.
