Cool Roof Design Options
For California steep-slope residential work, GAF publishes California Cool® reflective shingle options that can be used to comply with Cool Roof requirements of Title 24, Part 6 when the installed product/color meets required CRRC values. Design cards below list CA-available cool lines from our inventory research — eligibility is always verified for your address before permitting.
Title 24 Part 6 cool-roof compliance depends on climate zone, building type, roof slope, and the exact CRRC-rated product/color (aged reflectance / SRI / emittance). We verify current ratings for your address before permitting — the cards below are design options, not a blanket eligibility claim.

Systems Legend installs
GAF is one of North America’s largest roofing manufacturers. On residential roofs we commonly work with laminated asphalt shingle systems and matching accessories (starter, ridge, underlayment, and ventilation components) so the assembly is designed as one system. On low-slope and commercial projects we install GAF membrane systems such as EverGuard TPO when the building design calls for a single-ply approach.
Master Elite status reflects GAF’s contractor certification requirements (training, volume, and program standards). It is not a substitute for a careful site evaluation — it means we are set up to specify and install GAF systems the way the manufacturer intends, including eligibility for enhanced warranty pathways when product and installation criteria are met.
Materials & system components
- Timberline & laminated asphalt shingles — Architectural shingle looks for Central Valley homes; color and profile options reviewed on-site.
- Designer / higher-end GAF shingle lines — When curb appeal and dimensional profiles matter; specified by product availability for your ZIP.
- System accessories — Starter strips, ridge cap, leak barriers, and underlayments selected to match the shingle system.
- EverGuard TPO & low-slope membranes — Commercial and flat/low-slope assemblies (insulation, plates/fasteners, membrane) when the project is membrane-based.
- Ventilation & detailing — Ridge, intake, and flashing details coordinated with the roof system — especially important in Valley heat.
