Title 24 Cool Roof Requirements for a Sacramento Reroof
Anyone planning a reroof in Sacramento in 2026 needs to understand California's Title 24 Part 6 energy code, which sets minimum solar reflectance and thermal emittance requirements for most residential roofing products in the state's hot Central Valley climate zones. This guide explains what the cool roof requirement actually means for a Sacramento homeowner, which products qualify, and how it affects the cost and paperwork of a typical reroof project.

What Title 24 requires for Sacramento reroofs
California's Title 24 Part 6 Building Energy Efficiency Standards require most steep-slope residential roofing installed as part of a reroof in Sacramento's climate zone to meet minimum aged solar reflectance and thermal emittance values, intended to reduce cooling loads in a climate that regularly sees summer highs above 95 degrees. The requirement generally applies to reroofs, not routine minor repairs, and there are limited exceptions for small roof areas and some historic properties.
Compliant products are listed in the Cool Roof Rating Council (CRRC) directory, and most major shingle, tile, and metal roofing manufacturers now offer CRRC-rated options in standard colors and profiles, so homeowners are not limited to bright white reflective roofing to meet the code.
How cool roof products differ from standard roofing
Cool roof shingles use reflective granule coatings or pigments engineered to bounce back more solar energy than standard granules, which keeps the roof surface and attic space cooler and can meaningfully reduce summer cooling costs in a hot Sacramento attic. The visual difference between a CRRC-rated shingle and a standard shingle in the same color family is usually minor to homeowners, since manufacturers have developed cool-rated versions of popular dark colors.
Tile and metal roofing can also be CRRC-rated, often through reflective coatings or pigments baked into the finish, giving homeowners options across material types rather than forcing a switch to a different roofing system just to comply.
Cost impact of the cool roof requirement
Choosing a CRRC-rated product typically adds a modest premium to material cost, generally $500 to $2,000 on an average Sacramento reroof depending on the roofing material and specific product line selected, which is a small fraction of total project cost.
The compliance documentation itself, usually a CF1R-PRF form, adds no meaningful cost when handled by an experienced local contractor, since it is a standard part of the permit package for most Sacramento reroofs.
Exceptions and edge cases
Small roof areas below a certain percentage of total roof area, some steep-slope roofs meeting alternate insulation requirements, and certain historic buildings may qualify for an exception to the cool roof requirement, though these situations are less common on typical single-family reroofs.
Homeowners doing a partial reroof, such as replacing only a rear addition's roof, should confirm with their contractor whether the portion being replaced still triggers the requirement, since the rules apply based on the area being reroofed rather than the whole building.
Working with your contractor on compliance
A licensed C-39 roofing contractor working in Sacramento should already be familiar with Title 24 cool roof requirements and should proactively include CRRC-rated product options and the CF1R compliance form in their bid and permit paperwork.
Homeowners can independently verify a specific product's rating by searching the CRRC product directory using the manufacturer and product name before finalizing a material choice, which helps avoid a failed inspection or last-minute product substitution.
Typical cost ranges
| CRRC-rated asphalt shingle upgrade | $500 - $1,500 |
| CRRC-rated tile or metal roofing premium | $800 - $2,000 |
| CF1R compliance documentation | Included in most contractor bids |
| Standard reroof permit fee | $200 - $600 |

Common questions
Do all Sacramento reroofs need to meet Title 24 cool roof standards?
Most steep-slope residential reroofs do, though there are limited exceptions for small roof areas, certain insulation alternatives, and some historic properties.
Will a cool roof shingle look different from a standard shingle?
Usually not, since most major manufacturers now offer CRRC-rated versions of popular dark shingle colors that look similar to standard, non-rated products.
How much more does a cool roof product cost in Sacramento?
Typically $500 to $2,000 more than a standard non-rated product, depending on the roofing material and specific line chosen.
Where can I check if a specific roofing product is Title 24 compliant?
Search the Cool Roof Rating Council (CRRC) product directory by manufacturer and product name to confirm its solar reflectance and thermal emittance ratings before purchase.
