Fees and whether a mid-roof inspection is required are set by the city. Roofing is generally done by a licensed C-39 contractor.

The general picture
Re-roofing in California generally requires a permit from the local building department.

The exact fee, whether a mid-roof (in-progress) inspection is required, and the submittal format are set by each city — confirm with the jurisdiction below.
