Permits are applied for through the city's OmahaPermits.com (Accela Citizen Access) portal, and the Planning Department's "How to Get a Permit in Omaha" resources include a dedicated "How to Schedule a Roof Inspection with Photos" guide among its standard permit how-tos, alongside guides for creating a permit online, renewing a contractor license, and scheduling inspections online or by phone/text.

Roof inspections are scheduled through the city's permit system; the Planning Department publishes a dedicated "How to Schedule a Roof Inspection with Photos" guide, and inspections can be scheduled online or by phone/text per the department's how-to resources.

The Planning Department's Codes/Amendments page lists the city's current codes and amendments as: the 2018 International Residential Code (IRC), 2018 International Building Code (IBC), 2018 International Existing Building Code (IEBC), 2012 International Mechanical Code (IMC), 2023 National Electrical Code (NEC), and 2018 Omaha Plumbing Code (OPC), with the Fire Prevention Bureau enforcing the 2012 IFC and 2012 Life Safety Code.

Required — Drip edge is required at eaves and rake edges of shingle roofs (IRC R905.2.8.5). The jurisdiction adopted the 2018 International Residential Code via the city's complete 2018 IRC Amendments (eff. 7-1-2020; Ch. 9 amendments limited to R903.4, R905.2.5, flashing-gage sections and the R908 recover ban); that instrument, read in full, does not amend R905.2.8.5, so the code's drip-edge requirement stands as enacted local law.

Not required — Omaha Municipal Code Chapter 43 (Building), Article II (Building Code), Division 2 (Amendments), Section 43-127 "2018 International Residential Code," read in full as codified. Division 1, Section 43-121 adopts the 2018 International Residential Code as one of the city's building codes, and Section 43-127 sets out the city's amendments to it. Nine of those amendments fall within Chapter 9 (Roof Assemblies): Section R903.4 (roof drainage), Section R905.2.5 (fasteners), Table R905.2.8.2 (valley-lining gage), Sections R905.3.8, R905.7.6 and R905.8.8 (flashing gage, changed from 26 to 28), and Sections R908.3.1, R908.3.1.1 and R908.4 (roof recover deleted and barred, so a full tear-off is required). Section R902, roof classification, is not amended at all. At the state layer, Neb. Rev. Stat. Section 71-6403(1)(b) adopts the 2018 IRC by reference except Section R313 and Chapters 25 through 33, leaving Chapter 9 otherwise unmodified statewide. Neither layer contains any UL 2218, Class 4, or impact-resistance provision for residential roofing.

Table R301.2(1) as locally filled in by the City of Omaha (Complete 2018 IRC Amendments, effective July 1, 2020, p. 32): Ground Snow Load 25 psf, Wind Speed 115 mph, Seismic Design Category A. The table's Topographic effects, Special wind region, and Windborne debris zone columns are left blank (not filled in) in the published table -- reported as-is, not assumed "No." Footnote d states: "The jurisdiction shall fill in this part of the table with the wind speed from the ultimate wind speed map (Figure R301.2(5)A). Wind exposure category shall be determined on a site-specific basis in accordance with Section R301.2.14" -- i.e. 115 mph is the ultimate design wind speed, and exposure category is not fixed in the table but determined site-specifically.

"Section R908.3.1, Roof recover. Delete this section in its entirety. Section R908.3.1.1, Roof recover not allowed. A roof recover is not allowed. Section R908.4, Roof recovering. Delete this section in its entirely [sic]." (Complete 2018 IRC Amendments, effective July 1, 2020, p. 445) -- full tear-off of all existing roof coverings is required; no conditional recover/overlay allowance remains under the local amendment.

R905.2.1 (the 2018 IRC's solid-deck requirement for asphalt shingles) is not among the sections touched by the City of Omaha's Complete 2018 IRC Amendments (effective July 1, 2020) -- the amendment document, read in full, amends R905.2.5 (fasteners), R905.2.8.2/R905.3.8/R905.7.6/R905.8.8 (flashing gage 26-to-28), and R908.3.1/.3.1.1/R908.4 (recover ban), but contains no entry for R905.2.1. Because the local amendments leave that section untouched, the base 2018 IRC R905.2.1 text stands as enacted local law: "Asphalt shingles shall be fastened to solidly sheathed decks." No jurisdiction-specific gap tolerance or replacement trigger beyond that base solid-sheathing requirement was found in this document.

7.0% combined (.07) = Nebraska state rate 5.5% + City of Omaha local-option rate 1.5%, effective July 1, 2026, per the Nebraska Department of Revenue's Local Sales and Use Tax Rates schedule (Form 6-545-2024 Rev. 3-2026). Nebraska's local sales tax is state-administered, not self-collected by home-rule cities as in Colorado; no separate construction/use tax deposit at building-permit issuance was found for Omaha. Roofing contractors are taxed on materials, not labor, under one of three DOR 'contractor options' elected in the Nebraska Dept. of Labor's Contractor Registration Database (per the DOR's Nebraska Taxation of Contractors information guide, 6-346, rev. 10/2007 with 6/22/2011 updates): 'Option 1 contractors must continue to collect sales tax on the amounts billed to other contractors and project owners for building materials they annex during the project' (separately-stated labor is untaxed); 'Option 2 contractor labor charges are not taxable... Option 2 contractors will continue to pay sales tax on their purchases of building materials and fixtures' (contractor pays tax on cost, does not charge the customer); 'Option 3 contractors will continue to remit use tax on building materials and fixtures withdrawn from inventory' at 'the rate in effect at the time and place of withdrawal.' A contractor who does not register and elect an option 'will be treated as a retailer under Option 1.'
