Required

A permit is obtained in person at Aberdeen City Hall (123 South Lincoln Street, 3rd Floor) through the Building Inspection Department - the city's own "Permit Requirements" handout tells applicants a visit to City Hall is required "for review of your application, paying associated fees, and providing any other necessary material," and advises reviewing the applicable form first to potentially save a second trip. For roofing work such as shingle or metal-panel replacement, the City's 2026 Building Fee Schedule prices the permit off the project's total valuation ("Shingling, siding, windows & doors, and all other general remodeling" - valuation of project, using the fee chart), rather than a flat per-project fee; fees range from $35 for very small jobs up into a per-$1,000-of-value schedule for larger ones. All building or zoning permit fees are set by the city fee schedule on file with the finance officer (Sec. 12-111). Work started without first obtaining a required permit triggers a special investigation fee equal to the permit fee, on top of the permit fee itself (Sec. 12-111). A building permit is void if construction is not completed within two years of issuance for single-family dwellings and garages (Sec. 12-112(b)).

The City's own "Permit Requirements" handout states that "the nature and frequency of inspections conducted by the Building Inspection Department differs depending on the character of the work that was permitted for," and that it is "the duty of the person doing the work authorized by a permit to notify the Building Inspection Department that such work is ready for inspection." The handout does not publish a fixed, named sequence of inspections for roofing work specifically (e.g. it does not name a separate in-progress or mid-roof inspection apart from this general duty-to-request framework); applicants are directed to call the department at (605) 626-7017 with any project-specific inspection questions.

CITY-SET, not state-mandated. Aberdeen has adopted, at Chapter 12, Article II of the Aberdeen City Code (Sec. 12-11, "Adoption of residential code, building code, existing building code, mechanical code, and property maintenance code"): the 2018 International Residential Code (Chapters 1 through 11, Chapter 21, and Appendices H, J, M, and Q); the 2018 International Building Code (Chapters 1 through 35 except Chapter 27, plus Appendices C, E, F, G, and I); the 2018 International Existing Building Code; the 2018 International Mechanical Code; and the 2018 International Property Maintenance Code. The current text of Sec. 12-11 carries the citation history "(Code 2011, § 12-11; Ord. No. 17-03-02, § 2, 4-27-2017; Ord. No. 21-05-01, § 2, 6-10-2021; Ord. No. 21-08-02, § 1, 9-15-2021)", so the 2018-edition adoption in force today was most recently touched by Ord. No. 21-08-02, effective September 15, 2021. The city's local amendments to the adopted Residential Code and Building Code are separately codified at Sec. 12-21 and Sec. 12-31, enacted by Ord. No. 21-05-01, effective June 10, 2021. Context: South Dakota has no single mandatory statewide residential building code applicable to all jurisdictions - adoption is a local option - so the edition in force in Aberdeen is the city's own choice and does not carry over to other South Dakota cities, and this record does not resolve how Aberdeen's 2018-edition adoption interacts with any later state-level code framework.

Required — The City's own "Residential Shingling Guide" states: "Drip edge shall be provided at rake edges and eaves of shingled roofs. Adjacent roof edge segments must overlap not less than 2 inches. Drip edges shall extend back onto the roof deck not less than 2 inches and be mechanically fastened at not more than 12 inches on center. Underlayment shall be installed over the drip edge along eaves and under the drip edge along rake edges." Aberdeen has not omitted this provision - it is stated in full in the City's own published guidance. About drip edge

Required — The City's own "Residential Shingling Guide" states: "Aberdeen, SD is designated as an area subject to ice forming along eaves and thus causing water backup. An approved ice barrier shall be installed under all types of roofing unless specified otherwise by the manufacturer." The guide separately exempts detached garages and other unconditioned, non-habitable structures from the ice-barrier requirement, and states: "Ice barriers shall extend from the lowest edge of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. Roofs having a slope equal or greater than 8 units vertical in 12 units horizontal (8 in 12 pitch), the ice barrier shall be applied not less than 36 inches measured along the roof slope from the eave edge of the building." This matches the City's own amendment to Table R301.2(1) of the adopted 2018 IRC (Sec. 12-21(2)), which fills in "Ice barrier underlayment required" as "Yes." About ice & water barrier

Not required — Not established as a sourced affirmative, and Aberdeen is unusual in that it deliberately declines to publish an inspection sequence at all. I read both of the City's own relevant handouts in full. The 4-page "Residential Shingling Guide" (Building Inspection Department) is the city's roofing-specific document, with sections on General Requirements for Roof Assemblies, Reroofing, Roof Ventilation, Asphalt Shingles, Metal Roof Panels and Step Flashing - it imposes no inspection requirement of any kind, and contains no occurrence of "mid-roof," "dry-in," "notify," "call for" or "schedule"; its single instance of the word "inspection" is the Building Inspection Department's name in the letterhead. The 5-page "Permit Requirements" handout does carry a "Building Permit Inspections" heading, but rather than enumerating stages it says only: "The nature and frequency of inspections conducted by the Building Inspection Department differs depending on the character of the work that was permitted for. It shall be the duty of the person doing the work authorized by a permit to notify the Building Inspection Department that such work is ready for inspection. When questioning if an inspection is required, feel free to contact the City of Aberdeen Building Inspection Department for verification." So no mid-roof, dry-in, underlayment or ice-shield inspection is imposed by any Aberdeen document, and no enumerated residential inspection sequence is published anywhere for a roofer to plan against. SCOPE LIMIT, stated rather than glossed: this is a finding about Aberdeen's own overlay. The baseline inspection provisions of the adopted 2018 IRC are behind the ICC paywall and were not read, so this field records that the city adds no roofing inspection requirement, not that the model code contains none. PRACTICAL READING: a roofer should call 605-626-7017 and ask, because Aberdeen has reserved that answer to a phone call by design.

Not required — I read Aberdeen's own amendment ordinance to the adopted 2018 IRC (Sec. 12-21, 21 numbered items) and its own amendment ordinance to the adopted 2018 IBC (Sec. 12-31, 7 numbered items) in full, plus the City's own 4-page "Residential Shingling Guide" and 5-page "Permit Requirements" handout in full; none of these four documents addresses impact resistance, a Class 4 impact rating, or UL 2218. The amendment ordinances do not touch Chapter 9 (Roof Assemblies) of the IRC or Chapter 15 (Roof Assemblies) of the IBC.

Aberdeen sets no dollar-value or square-footage threshold below which a roof repair is exempt from permit. Sec. 12-112(a) of the Aberdeen City Code states flatly that "no person may erect, construct, reconstruct, alter, convert, or repair buildings, structures, or lands without first obtaining any building or zoning permit required under this Code or adopted technical code." The city's own "Permit Requirements" handout names "roof coverings such as asphalt shingles and metal panels" as an example of exterior repair work that requires a permit, and its separate, complete list of work that does NOT require a permit (retaining walls under 4 feet, small water tanks, painting/ papering, replacing interior finishes such as tile/flooring/trim/soffit/ fascia/gutters, small window awnings, playground equipment, and small prefab pools) does not include any roofing item. The city's own amendment to the adopted Residential Code's work-exempt list (Sec. 12-21(1), amending IRC Section R105.2) and its amendment to the Building Code's parallel list (Sec. 12-31(2), amending IBC Section 105.2) each touch only the accessory-structure and fence items and add no roofing exemption. No dollar-value threshold for roofing repair appears in any of these city instruments.

Table R301.2(1) (Climatic and Geographic Design Criteria) as filled in by the City of Aberdeen in its own amendment ordinance, Sec. 12-21(2) of the Aberdeen City Code: ground snow load 50 psf; wind design speed 115 mph; topographic wind speed-up effects No; special wind region No; wind-borne debris zone No; seismic design category A; weathering Severe; frost line depth 48 inches; termite none to slight; winter design temperature -10 degrees F; ice barrier underlayment required Yes; flood hazard date May 11, 1978; air freezing index 3,500; mean annual temperature 42 degrees F.

The City's own "Residential Shingling Guide" (Building Inspection Department) states, under "Roof replacement," that "roof replacement shall include the removal of existing layers of roof coverings down to the roof deck," with an exception letting an existing ice barrier membrane that is adhered to the roof deck remain in place and be covered with an additional layer of ice barrier. The same guide separately allows a "roof re-cover" - installing new roof covering over an existing one - where installed per the manufacturer's instructions, for complete separate systems such as standing-seam metal, or under special conditions over existing wood shake systems, but states a roof re-cover "shall not be permitted" where the existing roof covering is water-soaked or deteriorated, is wood shake/slate/clay/cement/ asbestos-cement tile, or "where the existing roof has two or more applications of any type of roof covering." In practice this allows recovering over one existing layer (reaching two total) before full tear-off is required, unless a bar or exception applies. Aberdeen's amendment ordinance to the adopted 2018 IRC (Sec. 12-21, read in full) does not separately touch Chapter 9 (Roof Assemblies), so this guidance reflects the base code's roof-recover framework as applied by the city's own published handout.

The City's own "Residential Shingling Guide" states, under "Asphalt Shingles": "Sheathing requirements. Asphalt shingles shall be fastened to solidly sheathed decks." The guide does not state a minimum sheathing thickness or material (e.g. OSB vs. plywood) beyond requiring a solid deck. Aberdeen's amendment ordinance to the adopted 2018 IRC (Sec. 12-21, read in full) does not separately touch Chapter 9 (Roof Assemblies).

The City's own "Residential Shingling Guide" states, under "Asphalt Shingles": "Attachment. Asphalt shingles shall have the minimum number of fasteners required by the manufacturer. For normal application, asphalt shingles shall be secured to the roof with not less than four fasteners per strip shingle or two fasteners per individual shingle. Where the roof slope exceeds 20:12, special methods of fastening are required. Asphalt shingles must be installed per manufacturer recommendations." For metal roof panels the same guide states attachment "shall be installed in accordance with the 2015 IRC and the manufacturer's installation instructions," and that metal roofing fastened directly to steel framing "shall be attached by approved fasteners" - note this metal-panel passage cites the 2015 IRC by name even though Aberdeen's currently adopted edition (Sec. 12-11) is the 2018 IRC; I record what the guide states rather than resolving the discrepancy. About roofing nails

South Dakota taxes roofing work primarily as a realty improvement under the state contractors' excise tax rather than as a retail sale of the finished job: the South Dakota Department of Revenue's own July 2026 Contractor's Excise Tax Guide states the tax is "imposed on the gross receipts of all prime contractors engaged in construction services or realty improvement projects in South Dakota" at a rate of 2%, and every contractor must hold a Contractor's Excise Tax License. Separately from that job-level excise tax, the materials a contractor purchases or receives for use in an Aberdeen project are subject to combined sales/use tax of 6.2% - the state's 4.2% state sales/use tax plus Aberdeen's own 2.00% municipal sales/use tax (the Department of Revenue's own January 2026 Municipal Tax Guide lists Aberdeen's general municipal tax rate as 2.00%, code 001-2). Aberdeen also levies a 1.00% municipal gross receipts tax (code 001-1), but per the same Department of Revenue chart that tax is limited to eating establishments, lodging, alcohol, and admissions, and does not apply to roofing contracts.
