Lancaster FAQ
Do I need a cool roof when I patch my existing roof?
Repairs of less than 50% of total roof area are exempt. Reroof projects exceeding that threshold trigger Title 24 cool-roof requirements with specific aged reflectance and emittance values matched to slope and climate zone.
Can I get a rebate for a cool roof?
Yes. SoCalGas, SCE, and LADWP for service-area customers, plus CRRC-rated material rebates from manufacturers, can offset costs. Check Energy Upgrade California listings for current cool-roof and heat-pump combined incentives.
Long Beach FAQ
Do small homeowner reroofs need cool roofs?
Steep-slope residential reroofs have flexible compliance paths. Most low-slope and large reroofs must use rated cool roof products under Title 24.
Is recoating an option?
Yes. CRRC-rated coatings can be applied to existing low-slope roofs to achieve required reflectance and meet reroof compliance.
