You'll spend more on a roof than on most cars, with less ability to test-drive it. The interview is your test drive. Good roofers answer these questions easily, they get them from every smart customer. Evasive, irritated, or vague answers are data too, and cheaper to collect now than after the deposit clears.

The company questions

1. 1How long have you operated under this exact business name? (Name changes can reset bad reputations.)
2. 2Can you send certificates of liability insurance and workers' comp directly from your insurer?
3. 3Are you licensed or registered for roofing in this state and city, where required?
4. 4Who actually installs, your employees or subcontractors? Who supervises on-site?
5. 5Three local references from one, three, and five-plus years ago, roofs age; so do promises.

The scope questions

1. 1Exactly which shingle line and class are you quoting, and why that one for this house?
2. 2What underlayment and how much ice and water shield, and where?
3. 3Which flashing is replaced versus reused, named by location?
4. 4How is decking priced if you find rot, per sheet, in writing?
5. 5What's your ventilation assessment for this attic, intake and exhaust?
6. 6Will starter strips and ridge caps be system components or cut field shingles?

The accountability questions

1. 1What does your workmanship warranty cover, for how long, and what voids it?
2. 2Does my material warranty reach the enhanced tier with your installation?
3. 3Who pulls the permit, and is the final inspection included?
4. 4What's the payment schedule, and is the final payment tied to my walkthrough?
5. 5If weather opens mid-job, how is my roof protected overnight?
6. 6How do you handle surprises, documented change orders or verbal adjustments?
7. 7Who do I call in year four when something drips, a person, or a voicemail?
8. 8What happens if I'm not satisfied at walkthrough?
9. 9Why is your bid different from the others, show me in the scope, not the adjectives.

Reading the answers

You're not grading roofing knowledge, you're grading specificity and comfort. Pros answer in details: product names, per-sheet prices, named flashing locations, real references. General reassurance is not a scope. Ask where each important answer appears in the estimate, contract, product documentation, insurance record, or closeout package. Specificity is earned. Hire the specifics.

Turn the interview into a comparable written scope

A good answer in the kitchen is useful only if it appears in the proposal. After each contractor visit, compare the written documents line by line: product names, quantities, tear-off, deck assumptions, flashing, ventilation, protection, cleanup, permits, payment timing, change orders, and warranties. If one proposal is silent, do not assume the missing work is included. Ask for the revision before choosing a price or signing an authorization. For the roofer interview checklist, circle every unanswered exclusion and require a written revision before treating the total as comparable.

• Verify the business identity, license where required, insurance, local address, and who will supervise the crew.
• Require exact product lines and system components instead of broad terms such as 'architectural shingle.'
• Define decking unit prices, change-order approval, and the evidence you will receive before concealed work proceeds.
• Put start conditions, material delivery, property protection, cleanup, inspections, and final payment in the contract.
• Separate manufacturer coverage, contractor workmanship responsibility, and any third-party warranty administration.
• For the roofer interview checklist, list unresolved exclusions separately so a blank line cannot become a surprise change order.

Compare exclusions before comparing totals

Turn every important interview answer into a comparable document. Ask who will supervise, what credentials and insurance apply, which products and installation instructions will be used, how decking, flashing, ventilation, penetrations, cleanup, permits, and weather protection are handled, and what can change the price. Then require those answers, exclusions, payment milestones, change-order rules, and warranty responsibilities in the proposal. A confident verbal answer is useful only when the signed scope preserves it.

A contractor may answer in different ways, but important omissions, conflicts, or refusals should be resolved before signing.

Turn the sales conversation into a comparable scope: Questions to ask a roofer

Require measurements, diagnosis, products, accessories, deck terms, flashings, ventilation or enclosure coordination, permits, cleanup, payment milestones, changes, exclusions, and warranties in writing. Another qualified contractor should be able to understand and price the same work. Apply that record to the questions to ask a roofer decision and identify which property finding or written term would change the answer.

Verify completion before releasing final payment: Questions to ask a roofer

Collect permit closeout where applicable, final photographs, product records, invoices, payment documentation, warranties, maintenance instructions, and correction of punch-list work. Separate manufacturer and workmanship coverage.
