Bloomington adopts the 2018 International Residential Code for One- and Two-Family Dwellings (City Code Chapter 10, Article II, Sec. 10-204, "with the additions, insertions, deletions and changes ... set forth in Article V"), amended by Ord. No. 2014-07, Ord. No. 2017-96, Ord. No. 2020-53 (8-10-2020) and Ord. No. 2020-67 (10-12-2020). Article V, Sec. 10-501, is titled "[Sec. R101.1 through Sec. R313.3] Modifications" and was read in full: it amends only R101.1 (title), Table R301.2(1) (climatic/geographic data), R105.2 (deletes five permit exemptions unrelated to roofing plus item 10), R112 (deletes Board of Appeals section) and the R313 fire-sprinkler series. It touches nothing in Chapter 8 (roof-ceiling construction) or Chapter 9 (roof assemblies), so the base 2018 IRC governs those unmodified.

Required — Bloomington's Article V amendment article, read in full, does not amend or delete the base 2018 IRC drip edge provision (R905.2.8.5), so the unmodified base-code requirement applies. About drip edge

Required — Bloomington's own Article V insert to Table R301.2(1), the Climatic and Geographic Design Criteria table, reads verbatim: "Ice shield under-layment required = Yes." This is the City's own filled-in table entry, not a base-IRC default. About ice & water barrier

Not required — Neither Bloomington's Article V amendment article (read in full) nor Illinois state law contains any UL 2218, Class 4/IV impact-rating, or hail-exposure provision reaching roof coverings. No impact-resistant roof covering requirement was found.

Bloomington's own Article V insert to Table R301.2(1) sets: Wind Design speed = 115 mph; Wind Design Topographical Effects = No; Seismic Design Category = B; Ground snow load = 30 psf; Weathering = Severe; Frost line depth = minimum 40 inches; Winter design temp = -4 deg F.

Bloomington's adopting instrument establishes the 2018 IRC (Sec. 10-204) and its own Article V amendment (read in full) amends nothing in the reroofing section. Base 2018 IRC R908.3.1.1, "Roof recover not allowed," bars a roof recover, among other conditions, "where the existing roof has two or more applications of any type of roof covering" -- one overlay allowed, two layers maximum.

Bloomington adopts the 2018 IRC (Sec. 10-204); its Article V amendment article, read in full, amends nothing in Chapter 8 (roof-ceiling construction, including roof sheathing), so the base 2018 IRC sheathing provisions apply unmodified. No local sheathing amendment was found.

Illinois taxes the roofer, not the job. Under 86 Ill. Adm. Code 130.1940(c), a construction contractor incurs no Retailers' Occupation Tax on labor or materials 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 example list. Repair and replacement are taxed identically: 130.1940(a)(3) defines "construct" to include "repair, renovate or remodel." The state rate has been 6.25% since January 1, 1990 (86 Ill. Adm. Code 130.101(c)(1)). The combined rate that actually applies is the rate at the supply house's counter or the contractor's own place of business (130.2075(b)(3)) -- NOT a rate keyed to the Bloomington job address; this session did not independently verify Bloomington's own local retail-rate component. The authoritative lookup is the Illinois Department of Revenue's MyTax Illinois Tax Rate Finder.
