Permit process note
The City lists a Roofing Permit among its building permit applications. The Building Inspection Division's "Residential Roofing Application / Permit" form asks whether the job is a complete tear-off and "How many layers are present?", and states: "Ice and Water Shield is required per IRC Table R301.2(1) & Ch. 9". Where wood is used, the applicant must "provide documentation verifying the product is a minimum Class C roof covering". The owner's affidavit certifies that the work "will conform to the regulations in the Codes adopted by the City of Raymore, specifically IRC Section R907 and all applicable ordinances."
Adopted code
The Building Inspection Division's page states: "City Council adopted a reorganized Chapter 500: Building Code and the most recent editions of the building codes utilized by the City to regulate the construction of residential and non-residential buildings. The current Raymore Building Code became effective Jan. 1, 2020, with local amendments." Its list of adopted codes includes "2018 International One and Two-Family Code (IRC)" and "2018 International Existing Building Code (IEBC)."
Ice & water shield
Required — Raymore City Code Section 500.175, adopting the 2018 International Residential Code with local amendments (Ordinance 2019-088, adopting a new Chapter 500), sets out Table R301.2(1), Climatic and Geographic Design Criteria, with YES under Ice Barrier Underlayment Required. About ice & water barrier
Mid-roof inspection
Required — The City's Residential Roofing Application / Permit form records two inspections under "Office Use Only": "Tear Off / Felt or Ice and Water Shield / Metal Flashings" and "Final Inspection / Job Completion". The first is taken at tear-off, before the new covering is complete.
Wind design criteria
115 mph wind speed; seismic design category A; ground snow load 20 psf; winter design temperature 6 degrees F. (Table R301.2(1) in Raymore City Code Section 500.175, Ordinance 2019-088; the table lists no topographic, special wind region or windborne debris entries.)
Roof layer limit / recover
Raymore City Code Section 500.175 (Ordinance 2019-088), amending the 2018 International Residential Code, enacts: "Roof replacement shall include the removal of all existing layers of roof coverings down to the roof deck." The same section deletes R908.3.1 Roof recover, R908.3.1.1 Roof recover not allowed, and R908.4 Roof recovering. Its exceptions allow an adhered ice barrier membrane to stay in place under a new layer of ice barrier membrane, allow complete and separate roofing systems such as standing-seam metal panels that do not rely on the existing roof for support, and allow a new protective roof coating over listed existing coverings. An asphalt shingle roof is torn off to the deck before re-roofing.
Sales & use tax
Raymore's combined sales tax rate is 9.1% (use tax 5.85%), jurisdiction code 60752-037-000, per the Missouri Department of Revenue's Jurisdiction and Total Rate Database for the fourth quarter of 2026. The same table lists 9 smaller rate areas inside the city where special taxing districts (community improvement, fire protection and transportation development districts among them) add tax, at a combined sales rate of 9.35% to 10.1%. Missouri's own state rate is 4.225%; the rest is local. For a re-roof, 12 CSR 10-112.010(1) provides that "a contractor is the final user and consumer of the materials and supplies used and consumed in fulfilling a construction contract and which become part of a completed real property improvement," so the roofer pays tax when it buys the materials. Under 12 CSR 10-112.010(2)(A), "In general, title passes after installation is complete," and where title passes after attachment the contractor "does not collect tax on its transfer of ownership or title of the item."
