Understand the terms used in the comparison.
Solar reflectance describes how much solar energy a surface reflects. Thermal emittance describes its ability to release absorbed heat. Solar Reflectance Index, or SRI, combines those properties into another comparison measure. A product’s color alone does not give you all of those values.
The Cool Roof Rating Council lists rated roof products and explains how ratings relate to California requirements. Ask for the exact product and color entry rather than a general statement that a manufacturer sells cool roofing. Different products or finishes can have different documented properties.
Apply the rules to this building and this work.
Cool-roof provisions are not one identical rule for every property. Building type, roof slope, climate zone, affected roof area, and the selected compliance approach can matter. Existing conditions and applicable exceptions need to be reviewed by the responsible project professional.
For current applications, check the 2025 Energy Code and the local requirements used by the permitting authority. The California Energy Commission identifies January 1, 2026 as the application-date start for that code cycle. Avoid relying on an older summary without confirming whether it fits the present project.
| Project detail | Question for the proposal |
|---|---|
| Roof and building | What building type and roof slope are being reviewed? |
| Scope | What roof area and work type does the compliance review cover? |
| Product | Which exact product, color, and CRRC rating are specified? |
| Documentation | Who supplies the compliance records and handles a substitution? |
Compare the roof system, not a rating in isolation.
The roofing product still needs to suit the roof geometry, supporting structure, installation details, and manufacturer requirements. A rated surface does not replace underlayment, flashing, drainage, or sound deck preparation. Ask how those items are included in the same scope.
If the selected product is unavailable, a replacement color or product should be reviewed before it is ordered. Keep the exact model and color tied to the written proposal. A last-minute substitution can change appearance, documented properties, and other details you thought had been settled.
Keep comfort and cost claims realistic.
A roof can be part of a building’s heat and energy discussion, but this website does not promise a particular utility saving or room-temperature change. Insulation, air leakage, shading, equipment, occupancy, and the rest of the building also affect performance.
Ask how the roof choice fits the building rather than buying a percentage claim with no project basis. Compare the complete installed cost, material appearance, maintenance needs, documentation, and written terms. The best next step is a property-specific explanation of the options that meet the project requirements.

Your questions, answered.
Does a cool roof have to be white?
Color alone is not the test. Ask for the rated properties of the exact product and color and compare them with the project requirements.
Is every CRRC-rated product compliant for my roof?
No. A rating provides product information. The project’s required values and compliance approach still need to be checked for the actual building and scope.
Will a cool roof guarantee lower energy bills?
No specific saving is promised here. Whole-building conditions and use affect energy performance, so a product rating is not a household savings guarantee.
Can I change the selected color after the estimate?
Discuss the change before ordering. The product rating, availability, appearance, and project documentation may need another review.
