How we measured this

We asked 10 questions a customer might ask about roofers in San Diego, CA, once on each AI tool, through each tool's official API. For example:

  • My roof is leaking in San Diego, CA right now. Which roofer should I call?
  • Who is the most trusted roofer in San Diego, CA?
  • Which roofing company in San Diego, CA is best for roof repair?

Perplexity searches the web and shows its sources. Gemini (model knowledge) answers without a web search, from what the model learned in training, so its picks can be out of date. A language model read each answer and listed the businesses it named, and a business counts once per answer. These results describe what AI said on these dates. They are not a rating of any business's work.
