Does Campbell require a cool roof?

In most cases. Climate zone 4, where the Energy Commission places Campbell (CEC climate zones), is a cool-roof zone. A reroof that replaces more than half of a sloped roof generally needs a rated product (aged solar reflectance 0.20 or more with emittance 0.75, or an SRI of 16), and a low-slope roof needs aged reflectance 0.63 and emittance 0.75 or SRI 75. Exceptions exist, so ask your roofer which apply (CEC).
