2013 California Title 24, Part 6 Requirements
Understanding How It Affects You
California’s Title 24 energy standards address the energy efficiency of new construction of, and additions and alterations to, homes and commercial buildings. Since buildings are one of the major contributors to electricity demand, the goal of Title 24 is to reduce energy consumption in California for its energy future.
Effective July 1, 2014, the Title 24 Roofing Code establishes new requirements to promote the installation of “cool roofs” in low-rise residential steep slope construction. Cool roofs consist of materials that reflect the sun’s energy from the roof surface, as well as have high emissivity, allowing them to emit infrared energy. Thus, significantly reducing energy costs and urban heat islands.
Northern California Roofing Company is committed to adhering to the Energy Commissions energy standards by providing our customers with cool roof concrete tile solutions that not only meet the new requirements, but deliver the beauty, durability and value that you’ve come to expect.

Requirements vary by zone, depending on the building and the climate method. To see which climate zone your project is in and the requirements associated with your building structure, visit the CEC’s website.
Roofing at It's Best
Re-Roof & Alterations
Home addition has less than 300 square feet of roofing
Minimum R38 attic insulation is used, provided
Minimum R4 above deck insulation is used
There is no ductwork in attic or duct insulation meets new requirements
High profile tile is used (rise to width ratio of 1:5 when installed)
Elevated battens are used
For new construction, the Performance Method — where you use the California Energy Commissions approved software to demonstrate compliance for the entire building — is the preferred path.
