Permit process note
The Building Inspection Division's Notice to Roofing Contractors states "Effective January 1, 2020, a permit is required to replace any amount of decking and/or over 100 square feet of roofing shingles." The same notice says that all roofing permits require a final inspection.
Adopted code
The City of Lancaster Building Permits & Inspections page states "The City of Lancaster adopted the 2021 ICC Model Codes with all NCTCOG local amendments" and lists the 2021 International Residential Code. The City's Adopted Ordinances page states "Effective March 24, 2025 the 2021 International Building Codes along with related construction codes were adopted by the City of Lancaster with amendments recommended by the North Central Texas Council of Governments." The City's Local Amendments document for the Residential Code is Ordinance No. 2025-03-15, which repeals the 2015 edition and adopts the International Residential Code, 2021 edition, with local amendments; it states it was "DULY PASSED and approved by the City Council of the City of Lancaster, Texas, on this the 24th day of March, 2025."
Drip edge
Required — Drip edge is required at eaves and rake edges of shingle roofs (IRC R905.2.8.5). The City adopted the 2021 International Residential Code by Ordinance No. 2025-03-15, a scanned document read in full from an OCR text; that instrument does not amend R905.2.8.5, so the code's drip-edge requirement stands as enacted local law. About drip edge
Ice & water shield
Not required — Table R301.2(1), as filled in by Ordinance No. 2025-03-15 (a scanned document read in full from an OCR text), enters "No" in the ice barrier underlayment column for Lancaster. About ice & water barrier
Impact-resistant roofing
Not required — Ordinance No. 2025-03-15, adopted March 24, 2025 and a scanned document read in full from an OCR text, contains no UL 2218, Class 4 or impact-resistance provision.
Wind design criteria
Table R301.2(1), Climatic and Geographic Design Criteria, as filled in by Lancaster Ordinance No. 2025-03-15 (the City's 2021 International Residential Code amendments, a scanned document read in full from an OCR text): wind design speed 115 mph (3 sec gust) / 76 fastest mile; topographic effects No; special wind region No; windborne debris zone No; ice barrier underlayment required No.
Roof layer limit / recover
Ordinance No. 2025-03-15, a scanned document read in full from an OCR text, does not amend the reroofing section (R908), so the adopted 2021 International Residential Code's own rule applies: a roof recover is barred "Where the existing roof has two or more applications of any type of roof covering." (R908.3.1.1 in the 2021 edition). One existing layer may be recovered; a second forces tear-off.
Sales & use tax
8.25% combined (6.25% state + 2% City of Lancaster), per the Comptroller's local sales tax rate file. Comptroller Publication 94-116, Real Property Repair and Remodeling, states that "Labor to repair, remodel, or restore residential real property is not taxable" and that under a lump-sum contract "you pay tax on all your supplies, materials, equipment, and taxable services when you buy them. You don't charge your customer tax." On a lump-sum residential re-roof the rate therefore falls on the roofer's material purchases, not on the homeowner's contract price.
