WHERE. The Building Inspectional Services Division sits inside Community Development, on 815-724-4072, with registration documents and permit applications submitted to [email protected]. ORDER OF OPERATIONS. File the free contractor registration before applying for the permit, since the City requires current registration on file before a permit can issue, then apply naming a full roof slope at a time. WHAT WILL STOP A PERMIT. A scope of work that mixes new and existing shingles on one slope, or a roof that already carries two coverings being recovered rather than torn off. MATERIALS. Reinstallation is permitted only for slate, clay, or cement tile, discarding damaged pieces and integrating new tile with old.

THE 2015 INTERNATIONAL BUILDING CODE AND THE 2015 INTERNATIONAL RESIDENTIAL CODE, ADOPTED BY A NAMED, DATED ORDINANCE, WITH NO CHAPTER 9 AMENDMENT. Code of Ordinances Section 8-175, most recently amended by Ordinance No. 17754, Section 2, adopted March 20, 2018, adopts both codes by reference. Its International Residential Code amendments, read in full, are: replacing Sections R101 through R114 with local administrative and enforcement text; requiring a 10 inch by 20 inch footing for single-family residences (Section R403); removing the plumbing and electrical chapters, Chapters 25 through 43; limiting the deck lateral-load connection requirement to decks over 30 inches (R507.2.4); removing the automatic fire sprinkler requirement of Section R313 for townhomes and one- and two-family dwellings; and removing Chapter 11 Accessibility in favor of the City's own Joliet Accessibility Code, Article XII of this same Chapter 8. None of these amendments touches Chapter 9, Roof Assemblies. Illinois itself has adopted no residential building code reaching an existing house (the Illinois Capital Development Board's own FAQ states plainly that the State has not adopted a building code for repairs to existing single-family residences), so Section 8-175 is the whole of the governing instrument, and it names a fixed 2015 edition rather than a floating reference to the current IRC.

Required — REQUIRED BY THE UNAMENDED BASE CODE; THE CITY'S OWN ROOFING PAGE DOES NOT USE THE TERM. Joliet's Section 8-175 amendments to the 2015 IRC do not touch Chapter 9, so the base code's drip-edge provision at Section R905.2.8.5 applies unmodified; that section is cited here as a pointer only and is not quoted, since it was not itself opened for this record. The City's own published roofing interpretation does not use the words "drip edge," though it does require solid sheathing and ice and water shield at eaves and valleys. About drip edge

Required — REQUIRED AT EVERY EAVE AND VALLEY, IN THE CITY'S OWN WORDS. The City's published interpretation of its Building Code reads, in full: "Underlayment shall be of an approved type. Ice and water shield shall be properly installed along all eave edges and in all valleys." The page states this as the City's own reading of the adopted 2015 International Building Code and gives no exception by roof pitch or by prior installation history. About ice & water barrier

Not required — NO UL 2218 OR CLASS 4 REQUIREMENT AT EITHER LEVEL. Section 8-175's amendments to the 2015 IRC, read in full, add no impact-resistance provision, and the City's own published roofing interpretation names no rating or standard. Illinois state law was read for this wave and returns zero occurrences of "UL 2218," "Class IV," or "hail" across every statute and rule that touches construction; the state's one "Class 4" hit is a felony grade in the roofing licensing act, not a hail rating. Neither the state nor the City imposes an impact-resistant shingle requirement.

NO DOLLAR OR SIZE FLOOR, AND PATCHING IS NOT AN OPTION AT ANY SIZE. The City's own published interpretation of its Building Code reads: "Any and all roof work will have to be permitted by the City of Joliet and must comply with the attached ordinance. Therefore the ordinance is enforced by the City of Joliet Building Department as permit applications that include a scope of work that violates the attached ordinance will not be issued a permit." The same page explains what "patching roofs is not covered as it is not permitted" means in practice: "Patching is defined as any number of shingle replacements on a given slope of the roof. Therefore any scope of work submitted for a roofing permit that includes the replacement of any number of shingles on a given slope that will result in the mixing of new shingles and remaining shingles will not be issued a permit for work. The City of Joliet will only permit full slope replacements and will not permit any patching of shingles for any given slope on a roof." The one exception is reinstalling slate, clay or cement tile, where damaged pieces are discarded and new tile is integrated with the old "so as to give the entire roof a uniform appearance." So a Joliet reroof permit covers a full slope at a time, never a spot repair.

TWO LAYERS MAXIMUM, FROM THE UNAMENDED 2015 INTERNATIONAL RESIDENTIAL CODE, AND THE CITY'S OWN PAGE STATES THE SAME RULE IN ITS OWN WORDS. Joliet's Code of Ordinances Section 8-175 adopts the 2015 IRC and amends nothing in Chapter 9, Roof Assemblies (see this record's adopted_code entry). Section R908.3.1.1 of that edition, Roof re-cover not allowed, bars a re-cover in three conditions, the third being "where the existing roof has two or more applications of any type of roof covering." One existing layer may be recovered; two forces a tear-off. The City's own published roofing interpretation states the same result without citing the section number: "Roof recovering with new materials shall not be permitted if the existing roof is water soaked, deteriorated, or does not have adequate base for recovering or the roof has two or more coverings."

SOLID SHEATHING IS REQUIRED ON A RECOVER, IN THE CITY'S OWN WORDS. The City's published interpretation of its Building Code, addressing roof recovering and repair directly, states in full: "Solid sheathing is now required." The page gives no further specification (material, thickness, or span), and the City's Section 8-175 amendments to the 2015 IRC do not touch Chapter 8's sheathing provisions, so the unamended base code governs the particulars.

9.00% COMBINED FOR MOST OF JOLIET (6.25% state, 1.00% Will County, 1.75% City home-rule tax), WITH A HIGHER RATE IN ONE BUSINESS DISTRICT, AND THE ROOFER RATHER THAN THE HOMEOWNER OWES IT. Under 86 Ill. Adm. Code 130.1940(c), a construction contractor incurs no Retailers' Occupation Tax on the labor or materials it incorporates into real estate as an integral part of a contract; instead "the construction contractor incurs Use Tax on the cost price of the tangible personal property that is incorporated into real estate," and roofing materials are named among the examples. Under 130.1940(a)(3), "repair" is included in the definition of "construct," so a patch, a recover, and a full tear-off are taxed the same way. The rate that applies is the one where the materials are purchased or at the contractor's own place of business under 86 Ill. Adm. Code 130.2075, not the rate at the job address. A portion of one Joliet zip code sits inside a special business tax district taxed at a higher combined rate. The authoritative source is the Illinois Department of Revenue's own MyTax Illinois Tax Rate Finder, a lookup tool rather than a static document; the 9.00% figure here is corroborated by third-party rate aggregators reporting the same state, county and City components.
