Registration details
  • license: STATE licensing, administered by the Minnesota Department of Labor and Industry. Minn. Stat. 326B.805, subd. 1 provides: "A person who meets the definition of a residential roofer as defined in section 326B.802, subdivision 14, must be licensed by the commissioner as a residential roofer, residential building contractor, or residential remodeler." Subdivision 3 makes it an offence to act or hold oneself out in that capacity for compensation without the licence, except as provided in subdivision 6. Moorhead publishes no city-level roofing registration of its own on the permit page read for this record; the state licence is the operative requirement.
Adopted code
STATE-GOVERNED, NOT CITY-SET. Moorhead enforces the Minnesota State Building Code; its residential chapter is the 2020 Minnesota Residential Code (Minnesota Rules chapter 1309), which incorporates the 2018 International Residential Code by reference and amends it. Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code, so Moorhead has no authority to adopt a different edition or to vary the code's content.
Drip edge
Not required — STATE-GOVERNED, NOT CITY-SET, and this is one of the places Minnesota departs from the base IRC outright. The 2020 Minnesota Residential Code prints Section R905.2.8.5, the drip-edge section, as a single word: "Deleted." Minnesota Rules part 1309.0905, subpart 2 is the instrument that does it — "Section R905.2.8.5 is deleted in its entirety." The Minnesota Department of Labor and Industry's guidance sheet states the consequence under its own "Drip edge" heading: "Drip edge is not required unless specifically required by the manufacturer's installation instructions." Moorhead has no authority to require one beyond that state baseline (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). The manufacturer's installation instructions remain a live route to a drip-edge requirement on a specific product. About drip edge
Ice & water shield
Required — STATE-GOVERNED, NOT CITY-SET — the requirement applies identically in Moorhead as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Moorhead has no authority to opt out (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.

Repair permit threshold
NO MINIMUM-SIZE THRESHOLD PUBLISHED. Moorhead names the work directly in its list of examples requiring a building permit: "Roofing and re-shingling," alongside new construction, replacing windows, doors or siding, adding a room, and installing or removing sheet rock. The City introduces the list as "Some examples include, but are not limited to," so it is illustrative rather than exhaustive, and no square-footage or dollar carve-out is published. Confirm a borderline small repair with Building Inspections at 218-299-5424.
Wind design criteria
STATE-GOVERNED, NOT CITY-SET, and uniform across Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) (Climatic and Geographic Design Criteria) to a single statewide set of values: ultimate design wind speed 115 mph, topographic effects "YES," and Seismic Design Category "A." The Minnesota Department of Labor and Industry's guidance sheet states the shingle consequence: "The 2020 Minnesota Residential Code requires shingles to be designed for a 115 mph maximum ultimate design wind speed (R301.2.1). This wind speed equates to a maximum basic wind speed of 90 mph, the same as required in previous codes. Asphalt shingle product labeling must indicate compliance with ASTM D3161 classifications A, D, F or ASTM D7158 classifications D, G, H and identify a maximum ultimate design wind speed of at least 115 mph (R905.2.4.1)." Ground snow load is the one input that varies geographically, and it is set by county rather than by city: Minnesota Rules part 1303.1700 fixes 60 pounds per square foot in twenty-nine named counties and "50 pounds per square foot in all other counties." Clay County is not among the twenty-nine, so ground snow load Pg is 50 pounds per square foot
Roof layer limit / recover
STATE-GOVERNED, NOT CITY-SET. The governing text is the 2020 Minnesota Residential Code, Section R908.3.1.1 (Roof recover not allowed), read in Minnesota's own merged code rather than inferred from the base IRC: "A roof recover shall not be permitted where any of the following conditions occur: 1. Where the existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing. 2. Where the existing roof covering is slate, clay, cement or asbestos-cement tile. 3. Where the existing roof has two or more applications of any type of roof covering." One existing layer may therefore be recovered; a second existing layer forces a tear-off to the deck. Moorhead has no authority to set a different layer limit — Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code.
Deck & sheathing requirements
STATE-GOVERNED, NOT CITY-SET. The 2020 Minnesota Residential Code, Section R905.2.1 (Sheathing requirements), reads in full: "Asphalt shingles shall be fastened to solidly sheathed decks or 1-inch thick nominal wood boards." Minnesota reaches that wording by amendment — Minnesota Rules part 1309.0905, subpart 1 amends the base IRC section to add the 1-inch nominal board alternative. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," expands on what qualifies: "Solidly sheathed roofs include structural panels such as plywood and oriented strand board (OSB) with 1/8" gaps between panels as required by panel manufacturers. Wood boards are also considered as solidly sheathed, provided the spacing between boards complies with the shingle manufacturer's installation requirements. If the spacing between boards is too large, a structural panel applied over the deck boards is required to be considered a solidly sheathed roof."
Sales & use tax
7.875% combined rate for Moorhead. Read from the Minnesota Department of Revenue's own "Local Sales and Use Tax Rate Guide" effective 7/1/2026 to 9/30/2026, Clay County table, "Moorhead" row: Other Local Rate blank, Other Area Rate blank (Moorhead is outside the seven-county metro area, so no Metro Area tax applies), City Rate 0.50% (Moorhead levies a city local-option sales tax), County Transit Rate 0.50% (Clay County Transit), State Rate 6.875%. Note for anyone quoting across the river: this is the Minnesota rate and does not reach work in Fargo, North Dakota — Combined Sales Tax Rate 7.875%.
