Greene County Resource Management Department, Building Regulations
Yes, a permit is required to replace a roof in Unincorporated Greene County, MO, issued by Greene County Resource Management Department, Building Regulations. A PERMIT IS THE COUNTY'S GENERAL RULE, AND ROOF WORK ON BOARD DECKING CARRIES ITS OWN COUNTY INSPECTION. The Building Regulations page states: "A permit is required when any owner or authorized agent intends to construct, alter, repair, move, demolish or change a structure." That clause names no roof work either way, and neither that page nor the notice below exempts a reroof. The County's Roof Deck Inspection notice of June 1, 2021 states that "Greene County will now require an inspection on the roof decking before any roofing coverings are applied," that "The deck inspection is required on one-by material only. An inspection of 4 X 8 sheet material will not be required," and closes: "Call for inspection once the 1-by decking is in place and before any roofing material is installed." The County's online Building Applications page lists its permit types (among them Remodel-Addition and Miscellaneous) and names no roofing category; this record does not decide which application a reroof is filed under. Call Building Regulations at 417-868-4015 before starting.

Permit process note
A PERMIT IS THE COUNTY'S GENERAL RULE, AND ROOF WORK ON BOARD DECKING CARRIES ITS OWN COUNTY INSPECTION. The Building Regulations page states: "A permit is required when any owner or authorized agent intends to construct, alter, repair, move, demolish or change a structure." That clause names no roof work either way, and neither that page nor the notice below exempts a reroof. The County's Roof Deck Inspection notice of June 1, 2021 states that "Greene County will now require an inspection on the roof decking before any roofing coverings are applied," that "The deck inspection is required on one-by material only. An inspection of 4 X 8 sheet material will not be required," and closes: "Call for inspection once the 1-by decking is in place and before any roofing material is installed." The County's online Building Applications page lists its permit types (among them Remodel-Addition and Miscellaneous) and names no roofing category; this record does not decide which application a reroof is filed under. Call Building Regulations at 417-868-4015 before starting.
Adopted code
THE 2012 INTERNATIONAL CODES, PER THE COUNTY'S OWN BUILDING REGULATIONS PAGE. The page states: "Greene County has adopted the 2012 International Codes, the 2011 National Electric Codes with adopted amendments, and Greene County Wastewater Standards." This record has not read the County's amendments to the 2012 codes and states no local amendment to the roof provisions either way. The County's June 1, 2021 Roof Deck Inspection notice is the County's own published roof-decking rule and is described in this record's deck and inspection fields.
Mid-roof inspection
Required — REQUIRED ON BOARD (ONE-BY) DECKING ONLY, NOT ON SHEET DECKING. The County's Roof Deck Inspection notice of June 1, 2021 states that "Greene County will now require an inspection on the roof decking before any roofing coverings are applied" and that "The deck inspection is required on one-by material only. An inspection of 4 X 8 sheet material will not be required." Its instruction to the roofer: "Call for inspection once the 1-by decking is in place and before any roofing material is installed." On a roof decked with 4 by 8 sheets the notice requires no deck inspection.
Repair permit threshold
Neither the Building Regulations page nor the June 1, 2021 Roof Deck Inspection notice states a dollar, area or percentage threshold for roof repairs, and the County's Building Applications page states none either. The Building Regulations page states the general rule: "A permit is required when any owner or authorized agent intends to construct, alter, repair, move, demolish or change a structure." This record has not read the County's amendments to the 2012 codes, including any amendment to the base code's list of work exempt from permit, and states no small-repair exemption either way. Ask Building Regulations about a small patch before treating it as permit-free.
Deck & sheathing requirements
SOLID DECKING, WITH COUNTY REPAIR CRITERIA FOR BOARD (ONE-BY) DECKING. The County's Roof Deck Inspection notice of June 1, 2021 states: "The requirements for roof decking require that the decking be a solid material." It sets these criteria for one-by decking: "If the decking has gaps over one-half inch (1/2") and knot holes over one (1") inch in size it will need to be repaired. One of the following repairs is acceptable: If the knot hole is over one inch (1") in size, the board can be replaced with a solid board with no knot holes. Covering the knot holes and gaps with a minimum 26 gage galvanized sheet metal will be acceptable. The metal has to be securely fastened to the roof decking below the underlayment. Knot holes or gaps over four (4) inches wide cannot be repaired. The board must be replaced." The notice says County inspectors had been "writing field corrections on one-by decking materials that have large gaps and knot holes." This record has not read the County's amendments to the 2012 codes and states no other local sheathing rule.
Sales & use tax
5.975% COMBINED SALES TAX RATE FOR UNINCORPORATED GREENE COUNTY (use tax rate 4.225%), per the Missouri Department of Revenue's Sales and Use Tax Rate Tables for July, August and September 2026 (updated 5/22/2026), jurisdiction "GREENE COUNTY," code 00000-077-000. A separate line, "GREENE COUNTY EAST-WEST ARTERIAL TDD" (00000-077-001), carries 6.475% for sales inside that transportation development district. On who pays, the Department's Contractors Tax Matrix (effective 10-24-2022) defines a contractor as "Any person entering into an agreement to improve, repair, replace, erect or alter real property" and lists "Purchases of parts, materials, supplies, and chemicals purchased by contractors" as Taxable, while "Contractor sales of tangible personal property where title passed to the customer after installation" are Exempt. In plain terms, a roofer pays the tax on materials at purchase rather than charging it on the installed roof. The matrix states that it "may not necessarily cover every situation."
