Confirm the roof scope and the property’s jurisdiction
A roofing project should have a clear administrative path as well as a clear construction scope. The property’s actual jurisdiction, the work being proposed and any material changes determine which approvals need to be resolved. The mailing city alone does not settle that question.
The roofing proposal should identify who handles required applications and inspection coordination. That lets you understand the process as part of the project instead of trying to classify the work yourself. Replacing a covering, repairing damaged decking and altering roof framing are different scopes and should be described that way.
