Roof coatings control the heat

Roof coatings are a commonly used material to reduce heat exposure and hardening of the vital asphalt waterproofing component of built-up roofing systems.
The ideal time to use coatings is during original installation, as it will immediately retard the aging process and significantly extend roof life. But coatings can also be used for preventive maintenance purposes. Applied to a previously installed roof, coatings will extend performance life.
Roofs 15+ years old that have not been maintained properly with coatings are generally not good candidates for preventive maintenance-type coatings. At some point, a roof system is so weathered that a core analysis of the roof membrane is required to determine the suitability of the roof’s condition to accept coatings.

Base flashings are an ideal place to use coatings, where about 90% of all roof leaks occur since they tend to degrade faster then the roof field. This degradation occurs because the vertical surface of the flashing receives intensive ultraviolet exposure, and the flashing membrane tends to be made of fewer materials than the roof field due to weight considerations related to the walls.

Acrylic elastomeric coatings can be tinted to produce various colors, but the most commonly used color is white because of its superior cooling effect on the roof. They maintain their reflectivity and emissivity as long as they are on the roof, but do degrade over time and lose thickness so re-coating is recommended every 7-10 years.
