Before the work starts
Rules for Lafayette
Permits
We handle your Contra Costa County roofing permit application and coordinate required reviews and inspections. You won’t need to manage the permit application or City paperwork yourself. County reroof base components are $150 plus $38 processing, before surcharges and any separate local approval charges. We obtain the total assessment for your roof. ARS allows approximately one week for permitting; issuance is not guaranteed.
Planning review
Most residential reroofs do not need separate Lafayette planning review. Reroofs in commercial, office and multifamily zoning need material and color review; we check the parcel’s zoning and coordinate any required roof-material submittal.
Roof-only waste-plan exemption
Residential reroof-only work under 5,000 square feet is exempt from Lafayette’s waste-plan requirement. We confirm the exemption and still handle the County building permit and inspection coordination.
Inspection during installation
We coordinate the County inspection while the new roofing is going on, followed by final. We confirm any deck or nailing inspection before work is covered and schedule the crew around the required approvals.
From the Lafayette building department and our own project records. Rules updated October 15, 2026; permit-fee references reviewed October 11, 2026; detailed inspection guidance checked October 10, 2026. Fees change, so we confirm yours when we pull the permit.
Inspections
Inspections and booking
County inspection holds — County stages are 123 Roof/In Progress, preferably 25–75% complete for composition, then 120 Final after completion. We confirm deck, repair and nailing holds—including code 108—before covering, and obtain approval at every assigned stage; a separate deck visit depends on the permit.
Final closeout — We confirm and coordinate the applicable requirements. Lafayette’s November 6, 2025 handout exempts residential reroof-only work under 5,000 square feet from City zoning plan check and WMP. Larger or combined scopes need applicability review; the exemption does not waive County inspections or other permit holds.
Booking — We book through County ePermits or 925-646-4108; we confirm current deadlines and availability before tear-off.
