METHOD AND LIMITS
How these lists were collected
- One answer per assistant, both collected on : ChatGPT with web search on and a US location, and Google Gemini with Google Search grounding and a US location, collected through cloro, a third-party AI answer collection service.
- The question, with San Antonio, TX as the city and state: “Who are the best commercial roofing contractors in [city], [state]? Give me a shortlist.”
- Answers change from day to day. Ask the same question tomorrow and either list can be different.
- Named by both: names are compared without punctuation, text in brackets, legal endings such as Inc. and LLC, and the city and state; they match when they are then the same, when one is the start of the other, or when both start with the same distinctive word.
- A listing here is not an endorsement by Sourci. Sourci has not vetted these companies, and the order is the assistant’s, not ours.

BEFORE YOU HIRE
How to check a commercial roofing contractor before you hire
An assistant’s shortlist is a place to start, not a vetting. Before you hire one of these commercial roofing contractors:
- Check the licence. Ask which licence or registration the company holds for this work. Licensing rules differ by city and by job size, so confirm what applies with the local building department before work starts.TEXAS LICENSING · NO STATE LICENCE FOR THIS TRADE
Texas does not require a state licence for reroofing contractors; ask the city's building or permit office whether it registers roofers and what permit the job needs.
Licensing body: none at state level.
“Texas does not currently require a state-issued license for reroofing contractors.”

- Ask for a certificate of insurance that names your property, and confirm it with the insurer.
- Ask for two or three references from similar commercial jobs and call them.
- Ask which roof system they propose and whether its manufacturer warranty needs a certified installer; if it does, check the manufacturer’s own contractor list.
- Get the scope, products, schedule and warranty in writing, and compare at least two proposals on the same scope.
FOR COMMERCIAL ROOFING CONTRACTORS
Are you a commercial roofing contractor in San Antonio? Here is what decides the list

ChatGPT cited the company’s own website for 6 of 6 (100%) of the names above, and Gemini for 1 of 5 (20%). A specific page for this service on your own site is the evidence both assistants used most.

And one list says little about the other: the two assistants agreed on 1 of these names. You need to check both.
