☑️ Title 24 Energy Efficiency Requirements

Contact Multiple Contractors

Get quotes from at least 3-5 licensed contractors in the Antioch area. Verify they hold an active California C-39 license and carry proper insurance. Don’t just go with the first estimate you receive.

Schedule On-Site Inspections

Never accept estimates over the phone or online. Professional contractors must inspect your roof in person to identify hidden issues, measure accurately, and assess structural conditions.

Request Detailed Breakdowns

Ask for itemized estimates that include materials (brand and grade), labor, tear-off/disposal, underlayment, flashing, ventilation, permits, and warranty information. Vague lump-sum quotes hide important details.
