Permit process note
The City's Roof Repairs letter, dated November 23, 2016, says "The City does not require permits for roofs unless the work is structural in nature." The Permits & Inspections page says the Engineering Department "performs building and plumbing inspections on all work requiring permits within the corporate limits of the City of Ellisville," and that electrical and mechanical permits are issued through St. Louis County.
Adopted code
THE 2015 INTERNATIONAL RESIDENTIAL CODE, PER THE CITY'S OWN PAGES. The Permits & Inspections page says the Engineering Department reviews plans "in accordance with the 2015 International Code Council (ICC) Building Code, The 2015 ICC Code for single- and two-family dwelling units and the 2015 ICC Plumbing Code." The City's Roof Repairs letter, dated November 23, 2016, says "We are currently under the 2015 IRC, and Table R301.2 (1) was adopted as indicated, and no other sections in Chapter 9 were modified." That letter predates this listing, and the adopting ordinance and the City's current municipal code were not read, so this record does not state whether later amendments exist. Missouri law leaves building codes to local adoption: RSMo 67.280 provides that a community "may adopt or repeal an ordinance which incorporates by reference the provisions of any code."
Drip edge
Required — This rests on the department's own written letter, dated November 23, 2016, which says "The City of Ellisville requires and enforces ice shields, felt, drip edges, flashing, and ventilation." The enacted amendment text was not read. About drip edge
Ice & water shield
Required — This rests on the department's own written letter, dated November 23, 2016, which says "The City of Ellisville requires and enforces ice shields, felt, drip edges, flashing, and ventilation." The enacted amendment text was not read. About ice & water barrier
Repair permit threshold
The City's Roof Repairs letter says it "does not require permits for roofs unless the work is structural in nature."
Sales & use tax
Missouri taxes the roofer on materials, not the homeowner on the job, and the combined rate is not keyed to the Ellisville job address in this record. The Department of Revenue's Contractors Tax Matrix lists "Tangible personal property to be sold as an attachment to real property" as Taxable on purchases by contractors, so a roofing contractor pays sales or use tax on shingles and underlayment when buying them. The Department states that "The state use tax rate is 4.225%" and that "Cities and counties may impose an additional local use tax," with the amount due depending on "the combined (local and state) use tax rate in effect at the Missouri location where the tangible personal property is stored, used or consumed." The rate in effect at a given address, including any special district rates, is on the Department of Revenue's Sales and Use Tax Rate Chart, which this record does not reproduce.
