Do I need a permit to replace a roof in San Antonio and how much is it?

The short answer

Yes, inside the City of San Antonio limits. The residential re-roof permit is $28.75 flat on the City's FY 2027 fee schedule, read October 19, 2026. The earlier FY 2026 edition, revised October 2025, listed this line at $25.00. Several roofing-company sites quote $150 to $500 for the permit; the Development Services Department fee schedule is treated as the authority here, and any difference on an estimate should appear as its own line.

The City's re-roof permit application also states a maximum of two layers of roofing material under the International Residential Code, so a roof already carrying two layers is torn off before a new one goes on.

The code text behind that cap is on the International Code Council's site. Section R908.3 of the 2021 International Residential Code says a roof replacement includes removal of the existing layers of roof coverings down to the roof deck, with an exception that lets an ice barrier membrane adhered to the deck stay where a new one is laid over it. The two-layer limit this page prints is the wording on the City's application form.

What the City file shows

The City of San Antonio Development Services Department publishes its issued permits as open data. We keep the rows typed "Re-Roof Permit": 29,235 of them from November 30, 2020 to September 25, 2026 (file built October 2, 2026; the City revises its file without notice, so recent counts can move). In the 12 months to September 25, 2026 that is 4,671 permits under 1,039 distinct permit holders.

Which districts and holders the permits sit under

The same file tags every re-roof permit with a council district and a permit holder. In the 12 months to September 25, 2026, District 7 records the most permits, 664, or 14.2% of the 4,671 in the window, and the other numbered districts follow in the table. The remaining 231 records sit outside a numbered district, carry no district, or name more than one.

The holder field names 1,039 distinct permit holders across the year and is blank on 254 records. The five holders with the most permits account for 988 of them, 21.2% of the year. A holder count measures applications filed under a name the City typed on the form, not the size or quality of a company.

The holders with the most re-roof permits

The table prints the five holders the file records most often in the 12 months to September 25, 2026, in the spelling the City used for the primary contact. The names mix roofing companies with individuals, and the file does not say whether an individual is an owner, a job site contact or the homeowner, so a high count is paperwork volume and nothing more.

The City's re-roof application asks for a Registration Holder and a City Registration number, and the FY 2027 fee schedule lists the Home Improvement Contractor license registration at $172.50, read October 19, 2026. A homeowner who pulls the permit personally attests to occupancy under City Code 10-115(a)(1) and takes on the inspections.

Paying the contractor

The Attorney General of Texas publishes a consumer guide to home improvement work. It recommends written bids from more than one contractor, notes that home improvement scams often follow violent storms, and says a homeowner should not pay in full until the work is complete and has been inspected. Where the improvement costs more than $5,000, the same guide says Texas law requires the contractor to put the homeowner's payments in a construction account at a financial institution.

A sale made at the home rather than at the seller's place of business carries a federal cancellation right. The Cooling-Off Rule, 16 CFR part 429, requires the seller to give a fully completed receipt or contract with a statement, in immediate proximity to the signature space, that the buyer may cancel before midnight of the third business day after the sale (rule text read 26 October 2026). A roofing contract signed at the kitchen table is the kind of sale the rule covers, so ask to see that statement before signing.

What this page does not tell you

It does not say whether your specific address needs more than the re-roof permit, and it does not read the City's permit-by-address search. Open the City's permit lookup with the address before work starts. Our own permit guide covers what the file records and how we read it.

It does not warrant the work. A permit is a building record, and the warranty on the materials and labour is a separate document: 15 U.S.C. 2302 requires a written warranty to disclose its terms and conditions fully and conspicuously in simple and readily understood language (text read 26 October 2026). Ask for the manufacturer warranty and the contractor's own warranty in writing before the crew starts.

How the San Antonio fee compares with four other Texas cities

The same stored fee file that holds the $28.75 line also holds one row for each of four other Texas permitting cities, every row read on October 19, 2026. Only the San Antonio row states a flat residential re-roof fee. Austin's residential fee schedule files returned 404 on the read day, Dallas prices alterations and repairs per dwelling unit without naming re-roofing, Fort Worth refused the read with 403 Access Denied, and the Houston fee calculator states no flat re-roof figure.

A Not published cell is not a zero and not a low fee. It means the city's own page did not state a number this site could quote, and the table links the page that was opened so a reader can check.

Source: the site's permit-fees.json, built October 19, 2026. The Dallas schedule does state a $181 base fee per dwelling unit for alterations or repairs of single-family and duplex structures; that line is not a re-roof fee and is not counted as one.

The months the re-roof permits are filed

Because the City file dates every re-roof permit, the month a roof is permitted can be counted. The six busiest months across the whole file are in the table, and all six fall between April and August. A busy month is a month when more paperwork was filed, not a measure of how long a job takes or when it starts.
