Broadway Truck Repair Center

Arkema Inc.

The Broadway Truck Repair Center is a 60,000 square foot corrugated steel facility located in Spokane Valley, WA. The project included roofing repair and recoating of the open-door depot. (Before and after photos are shown.)

United Coatings of Spokane Valley, WA supplied Roof Mate™ coating for waterproofing and KYMAX™ coating (Kynar Aquatec™ emulsion-based coating) for Total Solar Reflectance for this job. Seams, fasteners, and equipment were detailed out with Roof Mate™ and Roof Mate™ Butter Grade to waterproof the coating system. One coat of metal primer at 8 wet mils and one coat of white KYMAX™ (with an initial Total Solar Reflectance value of 0.87 as reported by the Cool Roof Rating Council) at 8 wet mils were used.

As one worker stated, “The section of the building with the repaired cool roof was significantly cooler than the unrepaired section.”

More than $40 billion is spent annually in the United States on electricity to cool buildings, which is about a sixth of the total electricity generated. And, these energy costs are rising in hot climate regions. White cool roofs have been proven to reflect the sun’s energy and reduce the roof surface temperature by up to 100°F. This reduction in temperature reduces the heat transferred into the building and lowers the electrical demand for cooling.

Kynar Aquatec™ based coatings have been reported by CRRC to have initial Total Solar Reflectance and Emissivity values greater than 0.85 each. Furthermore, additional south Florida exposure studies suggest that these coatings are expected to retain values over 0.80 for more than seven years. Conventional elastomeric acrylic based roof coatings drop to 0.55 Total Solar Reflectance in less than two years. These new fluoropolymer coatings are expected to revolutionize the roof coating market by providing long-term energy savings.
