Permit process note
The Development Services page "When is a Permit Needed?" introduces its list with "You need a permit if you plan any of the following:" and the list includes "Roof work", with no stated area or cost threshold. The Permits page states "Contractors must be registered with the City of Portland prior to any construction activities." and the City's Customer Portals page lists a Contractor Licensing Portal for registering as a licensed contractor in the Portland city limits.
Adopted code
The City of Portland's Adopted Code Amendments page states that City Council adopted Ordinance 2307 at its May 6, 2025 meeting, adopting the 2021 ICC building codes, and that "The codes went into effect on July 1, 2025." The page links a "2021 IRC Adopted Code Amendments" document for the 2021 International Residential Code.
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 2307; the City's 2021 IRC Adopted Code Amendments document, read in full, 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 — The City of Portland's 2021 IRC Adopted Code Amendments document (Ordinance 2307, effective July 1, 2025) fills in Table R301.2(1) with "N/A" under Ice Barrier Underlayment Required, so the table sets no ice barrier underlayment requirement. About ice & water barrier
Impact-resistant roofing
Not required — The City of Portland's 2021 IRC Adopted Code Amendments document (Ordinance 2307, effective July 1, 2025), read in full, contains no UL 2218, Class 4 or impact-resistance provision.
Wind design criteria
Table R301.2(1) as filled in by the City of Portland's 2021 IRC Adopted Code Amendments document (Ordinance 2307, effective July 1, 2025): wind design speed "As specified by the Texas Department of Insurance"; topographic effects No; special wind region No; windborne debris zone Yes.
Roof layer limit / recover
The City's 2021 IRC Adopted Code Amendments document (Ordinance 2307), read in full, 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 Portland), 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.
