Roofing in Oxnard

Back to city list

Re‐roofing in Oxnard requires a permit from Building and Safety and involves two inspections. The first is a roof nailing inspection, where an inspector will inspect the nailing pattern of the roof deck and a final inspection, to ensure the job was completed. A pre‐inspection is required if additional layers of roofing are installed over an existing roof. The City has no minimum requirements on the type of product to be installed and follows California’s 2007 Uniform Building Code. For additional information you may contact Building & Safety at 805‐385‐7925 or online at http://developmentservices.cityofoxnard.org/Department.aspx?DepartmentID=7&DivisionID=75.
