Berkeley FAQ
Does cool roof apply to a small repair?
No. Spot repairs under typical thresholds (often less than 50 percent of the roof) usually do not trigger Title 24 cool-roof requirements.
Can I keep a dark-colored shingle?
Steep-slope homes have flexibility, but the product must still meet aged reflectance minimums and carry a Cool Roof Rating Council label.
Oakland FAQ
Do I need a cool roof on my single-family home?
Cool-roof prescriptive requirements for low-rise residential roofs in Climate Zone 3 are limited; check current Title 24 tables and consult your roofer or Oakland Building Bureau before reroofing.
Are there incentives?
Some BayREN and PG&E energy-efficiency programs offer rebates for qualifying cool-roof and insulation packages; rebate availability changes annually so check before installing.
