Certified payroll for roofing subs (C-39) in California

The roofing trade's certified payroll reality

Roofer determinations frequently carry their own sub-classifications, kettle and pitch work historically among them, plus condition-driven premiums, and roofing's seasonal reality concentrates public work into tight summer windows on occupied campuses. That combination produces the classic roofing filing failure: a compressed schedule, a crew surging from five to fifteen, and certified payroll falling weeks behind exactly when the district's payment application needs it current. Solar-adjacent roofing adds a second wrinkle, since PV install hours can read under electrician determinations rather than roofer. If you run behind, the catch-up path matters more in this trade than any other: progress payments on summer work land after school starts, and missing filings are the first thing a district business office holds against them.

Whatever the craft mix, the mechanics are the same statewide: rates come from the project county's published determination (DIR lookup), the eCPR goes directly to DIR on non-exempt projects, and the federal WH-347 rides along weekly where federal funds apply. The full picture is in the complete guide.
