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.
