Cool Roof California TITLE 24

The State of California requires a “Cool Roof” when installing a new roof, or when re-roofing if the following criteria apply:

• Roof covers non-residential building, high-rise residential, or hotel/motel occupancy,
• Slope of the roof is less than 2:12,
• It is over air conditioned space,
• A permit is required.

To qualify as a cool roof, the material must meet the following criteria:

• A minimum reflectivity of 70%
• Minimum thermal emittance of 0.75,
• Products are labeled with CRRC label.

SBS modified bitumen roofing systems can achieve this by application of an elastomeric coating.  Our CSI-formatted specifications address the application of the coating.

We have developed a unique coating, which enables our system to achieve the California Title 24 requirement for “Cool Roof”.  This unique coating is a multi purpose 100% acrylic elastomeric coating for use over SBS modified bitumen membrane.  The base coat is applied at a rate of 1.5 gallons/square followed by the topcoat at a rate of 1.5 gallons /square.  For a total coverage of 3 gallons/square.
