California priority
California Cool Roof / Title 24 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 (and, where applicable, local rules such as LA County) when the installed product/color meets the required CRRC values.
- Timberline HDZ® RS (Reflector Series) — Architectural reflective shingles with EcoDark® granules; GAF states they can be used for Title 24 Cool Roof requirements — confirm color CRRC values for your climate zone.
- Grand Sequoia® RS — Designer-profile reflective shingles in the California Cool lineup; confirm current colors and CRRC ratings for the job.
- Standard Timberline / other GAF lines — Still installed widely; Cool Roof compliance is product- and color-specific — not every GAF shingle qualifies as a Cool Roof option.

PENDING OFFICIAL PDF — Cool Roof / Title 24 document for this brand will appear here when hosted on legendroofingcompany.com.
Cool Roof / Title 24 eligibility depends on climate zone, roof slope, project type (new vs re-roof), and the exact CRRC-rated product/color installed. We verify current ratings for your address before permitting — we do not invent eligibility on this page.

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.
