Our Cool Roofing Services
Cool roofs are designed to reflect more sunlight and absorb less heat than standard roofing materials. By maintaining lower roof temperatures, these systems reduce the amount of heat transferred into your home, lowering air conditioning demand and improving indoor comfort. Sure Roofing installs Title 24 compliant cool roof systems for Bay Area homeowners.
Cool Roof Installation
We install cool roofing systems on residential properties throughout the Bay Area. Our installation process includes selecting CRRC-rated materials appropriate for your climate zone, ensuring proper underlayment and ventilation, and verifying compliance with California energy standards. Cool roof installation can be incorporated into new construction or applied during a roof replacement project.
Cool Roof Replacement
When replacing 50% or more of an existing roof, California's Title 24 energy code requires compliant roofing materials in many climate zones. We handle the complete replacement process, from tear-off and sheathing inspection to installing CRRC-certified products that meet or exceed minimum solar reflectance and thermal emittance requirements.
Understanding Cool Roof Performance
Cool roof performance is measured by two properties: solar reflectance and thermal emittance. These values determine how effectively a roof rejects solar heat and releases any absorbed warmth.
Solar Reflectance
Solar reflectance measures how much of the sun's energy bounces off the roof surface rather than being absorbed. A roof with high solar reflectance stays cooler because it absorbs less heat. This works similarly to wearing a white shirt on a sunny day instead of a black one. Cool roof products have tested solar reflectance values, with aged ratings that account for three years of weathering.
Thermal Emittance
Thermal emittance measures how efficiently a roof releases absorbed heat back into the atmosphere. A roof with high thermal emittance cools down more quickly after the sun sets or when temperatures drop. Combined with high solar reflectance, strong thermal emittance keeps roof surfaces cooler throughout the day.
Solar Reflectance Index
The Solar Reflectance Index combines both properties into a single score from 0 to 100. Higher SRI values indicate cooler roof performance. California's Title 24 energy code specifies minimum SRI values for different climate zones and roof types, providing homeowners with a straightforward way to verify product compliance.
Title 24 Requirements for Bay Area Homes and Buildings
California's Building Energy Efficiency Standards, contained in Title 24, Part 6 of the Building Standards Code, regulate energy efficiency requirements for residential and nonresidential buildings. These standards divide California into 16 climate zones, with different cool roof requirements based on location, roof slope, and building type. Re-roofing commercial buildings and schools automatically triggers Title 24 compliance in SF County.
San Francisco Bay Area Climate Zones
Most of San Francisco, Marin County, and portions of San Mateo County fall within climate zones 2 and 3. These coastal zones experience moderate temperatures influenced by marine air and fog. While cool roof requirements vary by specific zone and project type, homes in these areas benefit from cool roofing's ability to reduce heat gain during warmer periods and maintain comfortable indoor temperatures.
When Cool Roof Requirements Apply
Cool roof requirements are triggered for new construction and for alterations where 50% or more of the existing roof surface is being replaced. Roof areas covered by solar panels are exempt from cool roof requirements, though uncovered areas must still meet applicable standards. Alternative compliance paths exist for homes with adequate attic insulation, radiant barriers, or other qualifying features.
CRRC Certification
All roofing products used for Title 24 compliance must be rated by the Cool Roof Rating Council. The CRRC tests products when new and after three years of weathering to establish aged performance values. Products display CRRC labels showing their solar reflectance, thermal emittance, and SRI values, allowing homeowners and inspectors to verify compliance.
Cool Roof Options for San Francisco Homes
Cool roof technology has expanded beyond white roofing materials. Modern products achieve high reflectance values in a range of colors and styles suited to different architectural preferences.
Reflective Asphalt Shingles
Cool asphalt shingles incorporate reflective granules that increase solar reflectance while maintaining traditional shingle appearance. These products are available in multiple colors and meet Title 24 requirements for steep-slope roofs. Manufacturers offer complete cool roof shingle collections designed specifically for California compliance.
Single-Ply Membrane Systems
TPO and PVC single-ply membranes are typically white and inherently reflective, making them natural cool roof choices for low-slope applications. These materials provide excellent solar reflectance without additional coatings. EPDM membranes, which are typically black, can be coated to achieve cool roof status.
Metal Roofing Systems
Metal roofs can be finished with reflective coatings that meet cool roof standards. Standing seam and other metal systems combine durability with energy efficiency, making them well-suited for Bay Area homes seeking both long lifespan and Title 24 compliance.
Tile and Concrete Products
Tile and concrete roofing products are available in cool roof formulations that meet California energy standards. These materials combine the traditional appearance of tile with modern reflective technology.
Benefits of Cool Roofing
1. Lower Energy Costs
Cool roofs reduce the heat transferred into your home, decreasing air conditioning demand during warm weather. According to the Cool Roof Rating Council, cool roofs can save 7 to 15 percent on total cooling costs. These savings are most significant in areas with long cooling seasons, but Bay Area homes also benefit during warm periods and heat events.
2. Improved Indoor Comfort
By keeping roof surfaces cooler, cool roofs help maintain more consistent indoor temperatures throughout the day. This can reduce hot spots in upper floors and attic spaces, improving overall comfort even in homes without air conditioning.
3. Extended Roof Life
Lower roof temperatures reduce thermal stress on roofing materials. The expansion and contraction cycle caused by daily temperature swings can accelerate wear on shingles, membranes, and other products. Cool roofs experience less extreme temperature variation, potentially extending material lifespan.
4. Reduced Urban Heat Island Effect
Cool roofs help mitigate the urban heat island effect, where developed areas become significantly warmer than surrounding rural land. By reflecting more solar energy back into the atmosphere, cool roofs contribute to lower ambient temperatures in neighborhoods and communities.

-
A cool roof is a roofing system designed to reflect more sunlight and absorb less heat than standard materials. Cool roofs achieve this through high solar reflectance and high thermal emittance, keeping roof surfaces cooler and reducing heat transfer into the building. California's Title 24 energy code sets minimum performance standards for cool roofing products.
-
Cool roof requirements depend on your specific climate zone, roof type, and project scope. Most of San Francisco falls within climate zones 2 and 3, which have specific requirements for new construction and roof replacements covering 50% or more of the surface. Alternative compliance paths exist for homes with adequate insulation or other qualifying features.
-
Look for the Cool Roof Rating Council label on product packaging. All compliant products must be CRRC-rated and display their solar reflectance, thermal emittance, and Solar Reflectance Index values. A qualified cool roofer can verify that products meet the specific requirements for your climate zone and project type.
-
Modern cool roof products are available in a wide range of colors. Reflective technology has advanced to allow darker-colored shingles, tiles, and coatings to achieve high solar reflectance values. Manufacturers offer complete cool roof collections in popular colors that meet California's Title 24 requirements.
-
A qualified cool roofer should understand California's Title 24 requirements, know which climate zone your property is in, and work with CRRC-certified products. They should be able to explain compliance options and help you select materials that meet both energy standards and your aesthetic preferences. Diamond Certified contractors like Sure Roofing have verified track records of quality work.
