A cool roof rebate in California comes from your local utility rather than a single statewide program, so what you can claim depends entirely on who supplies your electricity. The clearest published program is run by the Los Angeles Department of Water and Power, which pays residential customers between $0.20 and $0.60 per square foot for qualifying installations.1Los Angeles Department of Water and Power. Consumer Rebate Program Other utilities may offer similar incentives through their energy efficiency portfolios, but availability changes often. Confirm the program is active in your service area before you buy materials or hire a contractor.
How to Find Your Utility’s Program
California’s electricity market is split between investor-owned utilities such as PG&E, Southern California Edison, and SDG&E, plus municipal utilities like LADWP and SMUD. Each runs its own energy efficiency programs with different rebates, eligibility rules, and deadlines. Your service address decides which utility you belong to, and that utility is the only one whose rebates you can access.
Investor-owned utility programs are overseen by the California Public Utilities Commission, which has directed these utilities to contract with third-party companies to design and run many of their incentive programs.2Southern California Edison. Third Party Energy Efficiency Programs The rebate you want may not appear on the utility’s main rebate page; it might be administered by a third-party implementer with its own portal. If you don’t see a cool roof rebate listed, call the energy efficiency hotline and ask specifically about roofing incentives, including third-party offerings.
Municipal utilities operate independently of the CPUC and set their own rebate structures. If a municipal utility other than LADWP serves you, check that utility’s website or call them directly.
LADWP Rebate Rates and SRI Thresholds
LADWP’s Consumer Rebate Program covers single-family and multifamily residential customers. The rebate uses a two-tier structure based on the roofing material’s three-year aged Solar Reflectance Index (SRI), as rated by the Cool Roof Rating Council.1Los Angeles Department of Water and Power. Consumer Rebate Program
For low-slope roofs (2:12 pitch or flatter):
- Base rebate of $0.20 per square foot: three-year aged SRI of 78 or higher
- Enhanced rebate of $0.60 per square foot: three-year aged SRI of 85 or higher
For steep-slope roofs (steeper than 2:12):
- Base rebate of $0.20 per square foot: three-year aged SRI of 20 or higher
- Enhanced rebate of $0.60 per square foot: three-year aged SRI of 35 or higher
The gap between the two tiers matters on a real project. A 2,000-square-foot low-slope roof pays $400 at the base rate and $1,200 at the enhanced rate. Clearing the higher SRI threshold triples the rebate, often for a modest bump in material cost.3Cool Roof Rating Council. Cool Roof Fact Sheet and FAQ
What the CRRC Rating Means
Every cool roof rebate in California relies on ratings from the Cool Roof Rating Council, a nonprofit that tests and labels roofing products for solar reflectance and thermal emittance.4Cool Roof Rating Council. Roof Rating Program Solar reflectance measures how much sunlight the surface bounces back; thermal emittance measures how efficiently the surface releases absorbed heat. Together they produce the SRI score.
The number that counts for rebates is the three-year aged rating, not the initial rating. A roof’s reflectivity drops as it weathers and collects dirt, so codes and rebate programs use the aged figure because it reflects real-world performance.5Cool California. Cool Roofs: Codes and Standards A product with an impressive initial SRI of 95 might age down to 70 and miss the threshold. When you shop, compare aged values.
The CRRC keeps a searchable directory of rated products at coolroofs.org. Look up the specific product by manufacturer name or product ID before you buy, and verify the aged SRI meets your program’s threshold. If a product isn’t in the directory, it won’t qualify no matter what the manufacturer’s marketing claims.
Color is a weak proxy. Some darker “cool” products use pigments that reflect infrared while absorbing visible light, hitting high SRI values without looking traditionally reflective. The CRRC number is what counts.
Title 24 Is a Mandate, Not a Rebate
California’s Building Energy Efficiency Standards, Title 24 Part 6, set minimum cool roof requirements for most roofing projects statewide. The 2025 standards, effective January 1, 2026, specify minimum thermal emittance, three-year aged reflectance, and SRI values for both new construction and re-roofing work.6Cool Roof Rating Council. California Energy Code The exact minimums depend on your climate zone, building type, roof size, and slope, and hotter inland zones face stricter requirements than coastal areas.
For rebate purposes, the point is this: Title 24 compliance is mandatory for most re-roofs, so a basic cool roof is already the baseline. The rebate rewards you for exceeding that baseline. Some cities have adopted local rules that go further still.5Cool California. Cool Roofs: Codes and Standards Check your city’s green building code alongside the state standard.
Which Projects Qualify
Most programs cover retrofits and replacements of existing roofs. New construction typically doesn’t qualify, because Title 24 already requires cool roofing as a baseline for new buildings. The exception is when a new build participates in a whole-building energy upgrade program that goes well beyond code.
Residential programs generally cover single-family homes and smaller multifamily buildings. Some limit residential eligibility to specific climate zones where cooling demand is highest, since a cool roof saves the most energy inland and provides less benefit along the foggy coast. Commercial and larger multifamily projects are often routed through custom performance programs that require pre-approval and energy modeling; the rebate ties to calculated savings rather than a flat per-square-foot rate.
Application Documents and Deadlines
Rebate approval comes down to documentation, and a single missing item is the most common reason applications stall. Download the application from your utility’s program portal before the project starts and read every requirement. Some programs require pre-approval before installation begins, especially on commercial work, and starting early can disqualify you.
A typical application packet includes:
- The completed application form from the utility or third-party administrator
- An itemized invoice showing manufacturer, product model, CRRC product ID, square footage installed, and installation date
- The manufacturer specification sheet with CRRC-rated solar reflectance, thermal emittance, and SRI values
- Proof of purchase for materials and labor
- A copy of the approved building permit from your local jurisdiction
Watch the submission window. Programs typically require documentation within 90 days to 12 months of installation, and missing the deadline forfeits the rebate. Processing runs several weeks to a few months after submission, and the utility may inspect the roof before releasing payment. The rebate usually arrives as a check to the property owner, though some programs let you assign payment directly to a licensed contractor.
Practical Tips
Pull a roofing permit before work starts. California cities require them for re-roofs, with typical residential fees between $50 and $200. Skipping the permit leaves your rebate application incomplete.
Use a licensed roofing contractor. A C-39 roofing specialty license means the contractor knows the permit process and can supply the warranty and product documentation the utility will ask for. Some programs will only pay through a licensed contractor.
Look into stacking incentives. Certain reflective roofing products that meet Energy Star requirements may qualify for the federal Energy Efficient Home Improvement Credit under Section 25C on top of your utility rebate. The product requirements and credit amounts update periodically, so check with a tax professional before you count on a specific figure.
