The bid meeting is your best chance to learn the truth. Once the crew is on your roof, it is too late for doubts. That is why these questions to ask a commercial roofing contractor matter. Ask them all before you sign anything.
Write the answers down. Compare the three bidders side by side. The pattern will tell you who to trust.
questions to ask a commercial roofing contractor about credentials
Start with the basics. These first questions to ask a commercial roofing contractor separate the pros from the pretenders.
Are you licensed for commercial roofing work? Ask for the license number and check it with your state board. Commercial work often needs a different class of license than home roofing. Do not take their word for it.
Can I see your insurance certificates? You need general liability and workers compensation. Then call the insurer to confirm the policies are live. Paper means nothing until it is verified.
Are you certified by any roofing manufacturers? Makers of TPO, EPDM, and metal systems certify trained contractors. Certification unlocks stronger material warranties. It also proves the crew trained on your roof type.
How long have you done commercial roofs? Years in business predict whether the company will survive to honor its warranty. Ask how many commercial jobs they finish in a typical year. A company that lives on house roofs may fumble a flat membrane system.
Check the Better Business Bureau profile for each bidder. A clean record over many years is worth more than a slick sales pitch.
questions to ask a commercial roofing contractor about the job
Now the work itself. These questions to ask a commercial roofing contractor reveal how your project will really run.
Who will supervise my roof each day? Get a name and a phone number. The person who sells the job is rarely the person who does it. You want the foreman, not the salesman.
Will you inspect the roof before quoting? Any bid given without an on roof inspection is a guess. Good contractors walk the full roof, check drains and flashing, and probe soft spots. Refuse to consider blind bids.
What exactly is included in this price? Demand a line by line scope. Problem areas, materials by brand, labor, schedule, cleanup, warranty. If a line is missing, the work is missing too.
How will you handle hidden damage? Soaked insulation often hides under a small crack. Ask how they find it and how they price it when they do. A test cut before quoting is the honest method. For background on repair scope, see our guide to hiring a commercial roof repair company.
Questions About Money and Timing
Money questions feel awkward. Ask them anyway. These money questions to ask a commercial roofing contractor save the most pain.
What is the payment schedule? Standard practice is a deposit with the balance due when the work is done. Full payment up front is a red flag. Get the schedule in writing.
What warranties come with the job? You want the manufacturer warranty on materials and the contractor warranty on labor, both in writing. Ask what voids each one. Skipping maintenance can kill a warranty fast.
What happens when it rains? Open roofing must be covered the same day. Ask how they protect exposed areas and who decides to stop work. Water sitting on an open roof overnight is a disaster.
How long will my job take? Get a start date and a finish date in writing. Ask what delays are common. Weather is the usual one. A written schedule keeps everyone honest.
The National Roofing Contractors Association publishes fair practice guidelines for commercial roofing. Contractors who follow them answer these questions with ease. If your project may need financing, also read roofing companies near me that finance.
What Good Answers Sound Like
Good answers are specific. “We carry two million in liability, here is the certificate, call this number to verify” beats “oh, we are fully insured.” Listen for specifics in every one of the questions to ask a commercial roofing contractor on this list.
Good answers are calm. A pro welcomes hard questions. Pressure, dodging, or annoyance tells you the bidder fears scrutiny. There is always another bidder.
Good answers match the roof. If you have a metal roof, the contractor should talk fasteners, sealants, and panel profiles, not shingles. System specific knowledge proves real experience. For storm related work, see repair commercial roof.
Red Flag Answers
Watch for these warning signs.
- “We do not need a license for this size job.” Every commercial job needs proper licensing.
- “Insurance is too expensive, but we are careful.” Careful is not coverage.
- “Sign today for a special price.” Real prices do not expire at midnight.
- “We need half up front for materials.” A modest deposit is normal. Half is not.
- “The warranty covers everything, do not worry.” Vague warranties cover nothing.
One red flag can be a misunderstanding. Two mean you should walk away. Keep the full list of questions to ask a commercial roofing contractor handy during every bid meeting.

Frequently Asked Questions
How many questions to ask a commercial roofing contractor is enough?
Twelve covers the essentials, which is why this list has twelve. License, insurance, scope, money, schedule, and warranty are the pillars. Add system specific questions for your roof type. Stop when the answers repeat.
What if a contractor refuses to answer some questions?
Treat refusal as an answer. Honest contractors answer everything. A bidder who hides the license number or the insurance certificate is telling you the truth about themselves. Move to the next bidder.
Should I ask for references too?
Yes. Ask for five recent commercial jobs and call three. Ask if the crew finished on time and whether the roof stayed dry. Drive by one past job if you can. References plus sharp questions give you the full picture.
Can I ask these questions to ask a commercial roofing contractor over the phone?
You can start on the phone, but the real answers come on the roof. A serious bidder inspects before quoting. Use the call to screen for license and insurance, then invite the survivors to walk your roof.
