If you’re replacing a roof in Sacramento, California’s energy code, Title 24 Part 6, applies. Sacramento is in Climate Zone 12. The good news: for most re-roofs, meeting the rule is simple.
The easy way: install a cool roof
A cool roof reflects more sunlight than a standard roof. For most re-roofs, installing a cool roof meets the requirement. There are many compliant products and colors, and on a new roof they cost no extra. On shingle roofs, Owens Corning Oakridge Cool and Duration Cool are two options we install.

Other ways some homes qualify
On steep-slope homes (steeper than 2:12), the code has listed exceptions and alternatives. When we first wrote this post, the Sacramento City Building Department listed these:
- A heavy “mass” roof of 25 lbs or more, like a sod roof. This is rare.
- A 1-inch air space between the roof deck and the roofing, such as tile on raised battens.
- Roofing with a tall profile, where the rise is at least 1/5 of the width over half or more of the product.
- Ducts that already meet the code’s insulation and leakage rules.
- R-38 attic insulation. Many older homes only have R-19.
- A radiant barrier. It’s usually installed under new roof decking, so it’s easiest to add during a full re-roof.
- No ducts in the attic, such as some older homes with ducts under the house.
- R-4 insulation above the roof deck, with the required compliance form.
Code details change over time. Always confirm the current rules with your city or county building department, or ask us when we quote your roof.
What Title 24 Part 6 means for your project
For most homeowners, the simplest path is a cool-rated shingle or tile in a color you like. You don’t have to give up a dark color to meet the rule. See our 2027 roof replacement cost guide for typical prices, and roof replacement for how the process works.
