The Illinois Department of Financial and Professional Regulation lists "Roofing Contractor, Licensed" among the professions it licenses.

Adopted code
THE 2024 INTERNATIONAL RESIDENTIAL CODE WITH CITY AMENDMENTS, PER THE CITY'S OWN CODES PAGE AND ORDINANCE NO. 2026-1066. The City's Adopted Building Codes page lists the "2024 edition of the International Residential Code for One and Two Family Dwellings" and the "2024 edition of the International Energy Conservation Code," and links Ordinance No. 2026-1066, "Ordinance Replacing 4-1 With Updated Building Codes and Repealing Ordinance 2024-1039," adopted by the City Council on May 4, 2026, which the City posts as a scanned document. Its Section 4-1-5 adopts the 2024 residential code and Section 4-1-6 sets the City's changes to it. The City's Building Codes Update page posts the Building and Safety Office's sheet of amendments to the 2024 IRC, which deletes items from the permit-exempt list in R105.2 and replaces Table R301.2(1) with local design values; the roof-framing changes add "The use of 1X nominal lumber blocking shall not be allowed" to R802.8 and require that "Where eve venting is provided, insulation baffles shall be installed in all available rafter or joist bays to maintain air flow." Neither the sheet nor the ordinance pages this listing read amends the IRC's roof covering or reroofing provisions.
Ice & water shield
Required — REQUIRED, IN THE CITY'S OWN DESIGN TABLE. The Building and Safety Office's amendments to the 2024 IRC say "Section R301.2 (1) - Delete blank table and replace with the following," and the replacement table answers YES under ice barrier underlayment required. Section 4-1-6 of the City Code as enacted by Ordinance No. 2026-1066 carries the same table. This rests on the Office's own written sheet and the City's scanned ordinance. About ice & water barrier
Wind design criteria
The City's replacement Table R301.2(1), in the Building and Safety Office's amendments to the 2024 IRC and in Section 4-1-6 as enacted, sets a ground snow load of 23 lbs./sf, a wind design speed of 107 mph with no topographic effects, seismic design category C, severe weathering, a 36-inch frost line depth, moderate to severe termite damage, FEMA flood hazards, an air freezing index of 1500 and a mean annual temperature of 52.4 degrees F. The table does not state a wind exposure category.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Lincoln job address. Under 86 Ill. Adm. Code 130.1940(c), a construction contractor "does not incur Retailers' Occupation Tax liability as to receipts from labor furnished and tangible personal property (materials and fixtures) incorporated into a structure," but "incurs Use Tax on the cost price of the tangible personal property that is incorporated into real estate," with "roofing materials" named in the rule's own list of examples. Repair and replacement are taxed identically: 130.1940(a)(3) defines "construct" to include "repair, renovate or remodel." The Illinois Department of Revenue states the Use Tax rate as "6.25% of the purchase price or fair market value, whichever is greater." Where the contractor buys for resale, the local tax follows "the place of business at or from which the contractor or builder handles the transaction" (130.2075(b)(3)), so the combined rate on materials is the supply house's or the contractor's, which this record does not pin down. The authoritative lookup is the Illinois Department of Revenue's MyTax Illinois Tax Rate Finder.
