Cool Roof Rebate in California: LADWP Rates, SRI, and Title 24

A cool roof rebate in California comes from your electric utility, not from a single statewide program, so what you can collect depends entirely on who sends your power bill. The best-documented offer is the Los Angeles Department of Water and Power’s Consumer Rebate Program, 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 run their own energy efficiency programs with different rates, rules, and availability, and offerings change often. Confirm a current rebate with your utility before you order materials or sign a contract.

Find Out Which Utility Covers Your Address

California’s electricity service is divided between investor-owned utilities such as PG&E, Southern California Edison, and SDG&E, and dozens of municipal utilities including LADWP and the Sacramento Municipal Utility District. Your service address determines which one you belong to, and that utility is the only one whose rebates you can claim.

Investor-owned utility programs are overseen by the California Public Utilities Commission, which has pushed those utilities to hire third-party companies to design and run many incentive programs.2Southern California Edison. Third Party Energy Efficiency Programs A rebate you qualify for may not appear on the utility’s main rebate page because it lives on a separate implementer’s portal. If a cool roof rebate isn’t listed, call the utility’s energy efficiency line and ask specifically about roofing incentives and third-party programs.

Municipal utilities set their own programs independently. LADWP currently publishes the clearest terms, with specific rates tied to specific product ratings. Customers of other municipal utilities should check that utility’s website or call directly.

LADWP Rates and SRI Thresholds

LADWP’s Consumer Rebate Program is open to single-family and multifamily residential customers and uses a two-tier structure based on a product’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 (pitch of 2:12 or flatter):

  • $0.20 per square foot for a three-year aged SRI of 78 or higher
  • $0.60 per square foot for a three-year aged SRI of 85 or higher

For steep-slope roofs (steeper than 2:12):

  • $0.20 per square foot for a three-year aged SRI of 20 or higher
  • $0.60 per square foot for a three-year aged SRI of 35 or higher

The jump between tiers is worth planning around. On a 2,000-square-foot low-slope roof, the base rebate pays $400 and the enhanced rebate pays $1,200. Clearing the higher SRI threshold triples the payout, often for a modest step up in material price.3Cool Roof Rating Council. Cool Roof Fact Sheet and FAQ

What Makes a Product Qualify

Every California cool roof rebate depends on ratings from the Cool Roof Rating Council (CRRC), a nonprofit that tests and labels roofing products for solar reflectance and thermal emittance.4Cool Roof Rating Council. Roof Rating Program Those two values combine to produce the SRI score the rebate programs reference.

The number that counts is the three-year aged rating, not the initial rating. Roofs lose reflectivity as they weather and collect dirt, and rebate programs use the aged value because it reflects real performance.5Cool California. Cool Roofs: Codes and Standards A product with an impressive initial SRI of 95 can age down to 70 and miss the threshold. Compare aged values when shopping, and verify the product in the CRRC’s searchable directory at coolroofs.org by manufacturer name or product ID. A product that isn’t listed will not qualify, regardless of what the marketing says.

Color is a weak signal. Some darker products use pigments that reflect infrared while absorbing visible light, hitting high SRI values without looking traditionally reflective. The CRRC rating is what the rebate program reads.

Title 24 Sets the Floor, Not the Rebate

California’s Building Energy Efficiency Standards (Title 24, Part 6) require minimum thermal emittance, three-year aged reflectance, and SRI values for most roofing work statewide. The 2025 standards take effect January 1, 2026, and apply to nonresidential buildings (including hotels and motels), multifamily buildings, and single-family homes.6Cool Roof Rating Council. California Energy Code The exact minimums vary by climate zone, building type, roof size, and slope, and California has 16 climate zones with hotter inland zones facing stricter rules than coastal ones.

Compliance is mandatory for most re-roofing projects. If you’re replacing your roof, you likely need a cool roof whether or not a rebate exists. The rebate programs are rewarding you for exceeding the Title 24 minimum, not for meeting it. Check local green building codes too, since many cities have adopted stricter requirements than the state baseline.5Cool California. Cool Roofs: Codes and Standards

Which Properties and Projects Qualify

Rebate programs sort projects into residential, multifamily, and commercial categories, each with its own rules. Residential programs cover single-family homes and smaller multifamily buildings, and some restrict eligibility to climate zones with high cooling demand, since a cool roof saves far more energy inland than along the coast.

Larger multifamily and commercial projects are often routed through custom performance programs that require pre-approval and energy modeling. Total rebates can be larger, but payment is tied to calculated savings rather than a flat per-square-foot rate.

Most programs require a retrofit or replacement of an existing roof. New construction usually isn’t eligible because Title 24 already requires cool roofing as the baseline for new buildings. The uncommon exception is a new build enrolled in a whole-building efficiency program that goes well past code.

Documentation and Deadlines

Approval is a paperwork exercise, and a missing document is the most common reason an application stalls. Download the application form from your utility or program administrator before the project starts and read every requirement. Some programs, particularly on the commercial side, require pre-approval before installation begins, and starting work early can disqualify the project outright.

A typical application packet includes:

  • The completed application form from the utility or third-party administrator
  • An itemized invoice showing the manufacturer, product model, CRRC product ID, square footage installed, and installation date
  • The manufacturer’s specification sheet listing the CRRC-rated solar reflectance, thermal emittance, and SRI
  • Receipts for materials and labor
  • A copy of the approved local roofing permit

Watch the submission window. Programs require everything within a set period after installation, anywhere from 90 days to 12 months depending on the utility, and missing the deadline forfeits the rebate even if the installation itself qualifies. Processing can take several weeks to a few months, and the utility may inspect the roof before releasing payment. Rebates usually arrive as a check to the property owner, though some programs let you assign payment to a licensed contractor.

One practical note on contractors: California requires a C-39 roofing specialty license for roofing work, and some rebate programs will only pay to or through a licensed contractor. Pulling the local roofing permit is required for the application regardless; residential permit fees typically run between $50 and $200.

Stack a Federal Tax Credit on Top

A utility rebate covers only part of the cost. Certain reflective roofing products that meet Energy Star requirements may also qualify for the federal Energy Efficient Home Improvement Credit under Section 25C of the tax code, which can be claimed in addition to a utility rebate. Product eligibility and credit amounts are updated periodically, so confirm the current rules with a tax professional before filing.
