Adopted code
The Development Department's page says "The City of Smithville currently uses the 2018 International Code Council's Codes and the 2017 National Electrical Code," and lists the 2018 International Residential Code among the codes "All permits are subject to." The Development Department's FAQ adds that "The City has adopted the International Codes for Construction issued in 2018." The City's local amendments to the residential code are codified in its Municipal Code and were not read for this listing, so it does not say whether they touch Chapter 9, Roof Assemblies.
Repair permit threshold

The Development Department's FAQ says "Some items such as re-roofing your house or replacing existing windows do not require permits," and the City's "When do I need a permit?" sheet says "REPLACING ROOF DECKING REQUIRES A PERMIT" and "REPLACING SHINGLES DOES NOT." The sheet also says "If work begins prior to the issuance of a permit, the regular permit fee will be doubled."
