How AI assistants choose who to recommend for commercial roofing
We asked ChatGPT, Claude and Google AI Mode for commercial roofing recommendations 309 times. Here is what they needed to see on a roofer's page before naming it for a commercial building.
The short answer
Before naming a roofer for commercial work, assistants first needed proof it actually takes commercial jobs. Then they looked for references on buildings like the customer's, experience with the same roof system, insurance certificates, who backs the warranty, and a realistic start date.

What people actually asked
We asked for commercial roofing in three different ways. Here is each one, word for word, with how many of the 309 answers it produced between September 5 and October 14, 2026:
- “Commercial roofing near me — I'm in Clearwater, FL 33755. Who do you recommend?”104 answers
- “I'm looking to get commercial roofing done in Seminole, FL 33772 in two weeks. Who should I get quotes from?”103 answers, asked with five different timings: before the end of the month, in two weeks, in the next few weeks, sometime this month and next month
- “Who should I call for commercial roofing in 34683?”102 answers
Together, the 309 answers covered eight towns in Pinellas County: Clearwater, Largo, Palm Harbor, Pinellas Park, St. Petersburg, Dunedin, Seminole and Tarpon Springs. Each town came up in 38 to 39 answers. By assistant: ChatGPT 120, Claude 117 and Google AI Mode 72.
Customers also call it “light commercial roofing”, “commercial roof repair” or “commercial roof replacement”, so use those words on the page as well.
The question underneath all of them
“Do you work on our building type and existing roof system?” Commercial access, operating requirements and project authorization add questions beyond material choice.
What your commercial roofing page has to explain
Many roofers say they do residential and commercial work, but their pages and reviews are all about homes. Assistants often found a well-rated roofer and could not confirm it took commercial jobs, or which kinds. Some warned that residential roofers do not always do commercial work well. A page that names the building types and roof systems the roofer works on, with real commercial projects, removes that doubt.
The answers treated references as the main proof. Assistants told customers to ask for recent jobs on buildings of similar size and roof type, and even to call those building owners. They also asked whether the roofer has worked on TPO, EPDM, modified bitumen, built-up or metal systems. A project page that names the roof system and the roofer's role, such as full replacement or repair, gives a commercial buyer what they were told to ask for.
Commercial buyers also faced questions a homeowner rarely does. Answers asked for insurance certificates sent straight from the insurer, a written scope with permits and change-order terms, and whether subcontractors are used. They asked about material lead times, permit timing and what happens if weather hits mid-job. The page should explain how a project is scheduled and how the roofer works around a building that stays open.
What the assistants looked for before recommending anyone
We read all 309 answers to see what the assistants looked for before naming a company for commercial roofing, what they told the customer to ask, and what they said they couldn’t find.
What the assistants told customers to ask
Most common first:
Does the roofer work on this roof system?
Assistants told customers to ask about experience with their exact roof system, such as TPO, EPDM, modified bitumen, built-up or metal. Answers said experience varies a lot from one contractor to the next.
43% of the answers (134 of 309) brought this up.
Ask for recent commercial references with the same roof type as yours.
Has the roofer done buildings like this one?
Most answers told customers to ask for references from recent commercial jobs on buildings like theirs, with the same roof type and size. Some told them to call those building owners directly.
22% of the answers (68 of 309) brought this up.
Ask for references from buildings like yours, meaning the same roof type and size.
Can the roofer send an insurance certificate?
Many answers told commercial customers to ask for certificates of general liability and workers' comp insurance, sent directly from the insurer. This came up more often for commercial jobs than for homes.
22% of the answers (67 of 309) brought this up.
Ask for a certificate of insurance covering general liability and workers' comp, and confirm it with the insurer.
Is the scope written down, and who does the work?
Assistants told customers to get a written, itemized scope covering tear-off, permits, drainage, warranty and cleanup, with change-order terms. Some asked whether subcontractors are used and who supervises the crew.
19% of the answers (58 of 309) brought this up.
Ask each company for a written scope, warranty, permit responsibility, insurance certificates, license number, proposed start date, and change-order terms.
When can the work realistically start?
Answers told customers to ask for a realistic start date, warning that material lead times and permit approval can push installation out. Some asked how weather delays mid-job are handled.
12% of the answers (38 of 309) brought this up.
Ask each one for a realistic start date and what happens if the weather hits mid-job.
Who backs the warranty?
Assistants told customers to ask whether the warranty comes from the manufacturer, the contractor or both, and to get the terms in writing. Some also asked whether the system is rated for hurricane winds.
12% of the answers (36 of 309) brought this up.
Ask whether the warranty comes from the manufacturer, the contractor, or both, and whether the system is rated for hurricane winds.
What the assistants couldn’t find
In 37 of the 309 answers, the assistant said it couldn’t find or confirm something it needed about a company. By assistant: Claude in 37 of its 117, ChatGPT in 0 of its 120 and Google AI Mode in 0 of its 72. As we asked it, Claude usually says what it couldn’t confirm; ChatGPT and Google AI Mode seldom do, so these counts mostly show what Claude couldn’t find. Most often:
- A phone number or other way to reach the company: 23 answers
- Reviews it could check: 5 answers
Assistants most often could not find a phone number, and often could not confirm that a roofer took commercial work at all. A commercial page with its own contact line and real commercial projects answers both.
Its listing doesn't mention commercial work, so ask whether they take it on.
Where the assistants sent people
Each answer linked to the pages the assistant relied on. Of the 237 ChatGPT and Claude answers about commercial roofing, this is how many linked at least once to each kind of site:
- A contractor’s own website: 99% (235 answers)
- A directory or review site such as Yelp, Angi or the BBB: 71% (169 answers)
- A manufacturer or home-improvement guide: 25% (59 answers)
- An official license lookup: 17% (41 answers)
A contractor’s own website was the page linked most often, so your site is usually what the customer is sent to read.
Google AI Mode works differently. In 65% of its 72 answers, the links opened Google’s own listing for a business rather than a website. There, your Google Business Profile is the page the customer sees, so it needs the same facts as your site.
The checks behind every recommendation, applied to commercial roofing
Can the customer reach a person?
Phone numbers were what assistants most often could not find for this job. Some found more than one number across directories and could not tell which was current.
23 of the 309 answers about commercial roofing, 23 of them from Claude, said the assistant couldn’t confirm this. In our July–August study across eight trades, it cost a business its place in 147 of the 290 conversations where it came up.
What do recent customers say?
Assistants often found directory rankings that were not owner-verified, or ratings from the company's own site. They told customers to check Google and BBB and call commercial references.
5 of the 309 answers about commercial roofing, 5 of them from Claude, said the assistant couldn’t confirm this. In our July–August study across eight trades, it cost a business its place in 139 of the 569 conversations where it came up.
Can you schedule the job when the customer needs it?
Many buyers had a deadline, such as finishing before month's end. Assistants told them to ask about crew and material availability up front, and about temporary repairs if the roof leaks before work starts.
2 of the 309 answers about commercial roofing, 2 of them from Claude, said the assistant couldn’t confirm this. In our July–August study across eight trades, it cost a business its place in 185 of the 657 conversations where it came up.

Your commercial roofing page checklist
Work through this list on your commercial roofing page. Each item answers something the assistants looked for above.
- Use “commercial roofing”, “light commercial roofing” or “commercial roof repair” in the page title, the main heading and the first paragraph.
- List the commercial roof systems you install and repair, and link each one to a finished project.
- Show real commercial projects by building type and size, and offer references a buyer can contact.
- Say what commercial insurance you carry and that certificates are sent from your insurer on request.
- Describe what your written commercial proposals include, and say who supervises the job and whether you subcontract.
- Explain your usual timeline from inspection to start, including permits and materials, and how weather delays are handled.
- State the manufacturer and workmanship warranties you offer on each system, and who stands behind each one.
- Put one working phone number for commercial work on the commercial page, and keep it the same everywhere.
- Link to recent independent reviews, and point to ones from commercial building owners or managers.
- Say how soon you can walk the roof and quote, your usual lead time, and whether you do temporary repairs.
Going further: let assistants see real openings
For planned work like commercial roofing, a useful opening says whether it is for an assessment or the job itself, and whether the customer’s address is covered.
Merchant Context builds custom integrations with scheduling software so customers and AI assistants can read your current availability. Where your system records the job type, service area, duration and crew capacity, the integration can show those details with each opening, so an assistant can match it to the request instead of guessing.
We scope each connection to the software and data you actually have. A displayed opening is not a confirmed booking: the customer still confirms through your normal booking process, and the information is only useful while it is fresh.

Questions owners ask
What should I ask a commercial roofer before hiring?
Answers about this job most often told customers to ask for references on similar buildings and experience with the same roof system. They also asked for insurance certificates, who backs the warranty, a realistic start date and a written scope. A page that answers these makes a roofer easier to choose.
Does a residential roofer do commercial roofs?
Some do, but assistants warned that flat and low-slope commercial roofs are different work from residential shingles. They told customers to ask for recent commercial references. A roofer that takes commercial jobs should show them on its page.
How long does a commercial roof project take to start?
Assistants said quotes can come quickly, but material lead times and permit approval can push the start out. They told customers to ask each roofer for a realistic start date. A page should explain the usual timeline and what affects it.
Which AI assistants did you test?
ChatGPT, Claude and Google AI Mode. Between September 5 and October 14, 2026, they answered 309 questions about commercial roofing: ChatGPT 120, Claude 117, Google AI Mode 72.
Will these changes guarantee a recommendation?
No. Nobody can promise that. These changes supply what the assistants were looking for in our research. Whether they move recommendations for your business is something to measure after they go live.
How we got these numbers
The questions, counts and quotes on this page come from the 309 answers ChatGPT, Claude and Google AI Mode gave between September 5 and October 14, 2026. We asked for commercial roofing in eight towns in Pinellas County, Florida. We collected them with software rather than the consumer apps, which can answer differently. We counted what each answer mentioned, what it said it couldn’t find and where it linked. Quotes never name a business.
The study figures come from an earlier set of assistant conversations in July and August 2026 across eight trades, coded for the reason each business was included or left out. Counts overlap and are never added together.
