Chino FAQ
Does Title 24 apply to existing homes?
Major re-roofing replacing more than half the roof area triggers cool-roof compliance. Minor repairs and patches are usually exempt under the existing-building provisions of Title 24.
Is white the only cool roof color?
No, cool-roof pigments allow earth tones with high reflectance. Many CRRC-rated products in tan, gray, and brown colors meet Title 24 reflectance and emittance values for desert climate zones.
