Required — Not separately amended by the City of Sterling. The City adopts the 2018 IRC by reference (Code of Ordinances § 5-56) with only four lettered amendments (a)-(d), none touching roofing, R905, or Chapter 9, so the base IRC drip-edge requirement (R905.2.8.5) stands as adopted code. About drip edge
Impact-resistant roofing
Not required — City of Sterling Code of Ordinances § 5-56 (Amendments to the International Residential Code) contains only four lettered items (a) through (d) -- plumbing/electrical exception, a Sleeping Room definition, and deletion of R313 Automatic Fire Sprinkler Systems -- and no others; read in full, ending cleanly on its own history note. No UL 2218 or Class 4 impact-resistant-shingle mandate appears anywhere in the section.
Roof layer limit / recover
The City's Reroof Permit Application form (Public Works Department, Code Enforcement Division) requires the contractor to state the "NUMBER & Type of layers removing" and instructs in bold: "(ALL LAYERS MUST BE REMOVED)". Consistent with the record's own permit_process_note ("All existing roof covering layers must be removed before the new covering is installed"). No recover over an existing layer is permitted; full tear-off is always required for a Sterling reroof permit.
Sales & use tax
7.0% combined (state 2.9% + Logan County 1.0% + Platte Valley RTA 0.1% + City of Sterling 3.0%). Home-rule, self-collected — the City's own Finance page states the Sales Tax Technician "is responsible for the administration, collection and enforcement of the City's sales tax." Use tax is not separately broken out on the City's own page beyond this combined rate.
