What Questions Should You Ask a Roofing Company Before You Sign?

Quick Answer \u2014 The 5 Must-Asks

“What’s your license number, and can I verify it on the state portal?”
“Send me certificates of insurance — liability and workers’ comp — directly from your insurer.”
“Will the estimate be itemized: exact products, underlayment, flashing, ventilation, decking pricing?”
“Who installs the roof — your employees or subcontractors — and who is on site every day?”
“What exactly does your workmanship warranty cover, for how long, and is it transferable?”

A printed roofing contract and itemized estimate document beside a pen on a wooden kitchen table — The fifteen minutes you spend on these questions is the cheapest part of any roof project \u2014 and the part with the highest return.

What Should You Ask a Roofing Company Before Hiring?

Direct answerStart with the five essentials \u2014 license verification, insurer-sent insurance certificates, an itemized written estimate, a clear answer on who actually performs the work, and the written workmanship warranty in full. Then move to materials, installation methods, and payment protection.

Questions are leverage. Asked before signing, they cost a roofing company nothing but honesty; asked after a leak, they cost you thousands. The sequence below is organized the way risk actually stacks: first the questions that protect you from catastrophe (uninsured injuries, unlicensed work), then the ones that protect you from a bad roof (spec shortcuts, missing ventilation), then the ones that protect your wallet and warranty (payments, change orders, cleanup).

A fair warning from the contractor\u2019s side: good companies want these questions. We answer them dozens of times a season, we keep the paperwork ready, and a homeowner who asks them is usually the same homeowner who pays on schedule and refers neighbors. The companies that bristle are not protecting trade secrets \u2014 they\u2019re protecting shortcuts. Every question below includes the answer a professional gives, so you\u2019re not left guessing whether a reply was good.

Which Licensing and Insurance Questions Come First?

Direct answerQuestions one through five establish that the company legally exists, carries real coverage, and has survived locally long enough to honor a warranty. Nothing about shingles matters until these five come back clean.

1. \u201cWhat is your contractor\u2019s license number, and may I verify it on the state portal?\u201dWhy it matters: a professional answers with the number instantly. Look it up \u2014 confirm it\u2019s active, in good standing, and held under the same company name on the estimate.
2. \u201cCan you have your insurer email me certificates for general liability and workers\u2019 compensation?\u201dWhy it matters: expect a standard $1,000,000 liability policy plus comp for everyone on your roof. Insist the certificates come from the insurer, not a scanned PDF \u2014 and call to verify.
3. \u201cHow many years have you operated under this exact company name?\u201dWhy it matters: names change when reputations do. Three-plus years locally under one name is the credibility bar; ask what the company was called before if it\u2019s newer.
4. \u201cWhat\u2019s your local business address, and where does the crew come from?\u201dWhy it matters: a truck and a P.O. box can\u2019t service a warranty. Local crews mean local accountability \u2014 and a foreman you can find again in year five.
5. \u201cWho pulls the permit for this job?\u201dWhy it matters: the contractor should pull it, always. \u201cNo permit needed\u201d or \u201cyou can pull it yourself\u201d hands liability and inspection problems to you.

What Should You Ask About Materials and Installation Methods?

Direct answerQuestions six through ten pin down the spec: the exact product by brand and line, what\u2019s underneath it, how valleys and flashings are built, and how the attic breathes. This is where a bargain bid hides its discounts.

6. \u201cWhich shingle or panel \u2014 exact brand, product line, and warranty tier \u2014 goes on my roof? Can I see the spec sheet?\u201dWhy it matters: \u201carchitectural shingle\u201d spans products decades apart in quality. The spec sheet is the contract between you and the material.
7. \u201cWhat underlayment do you use, and where does ice-and-water barrier go?\u201dWhy it matters: synthetic underlayment and self-adhering barrier at eaves and valleys are what make a \u201c50-year roof\u201d last 50 years. Builder-grade felt here is a red flag.
8. \u201cWhat\u2019s your ventilation plan \u2014 how much intake and exhaust will my roof have?\u201dWhy it matters: the International Residential Code\u2019s 1:150 baseline needs real intake at the soffit, not just a ridge vent on top. Unbalanced venting cooks shingles from below.
9. \u201cHow do you handle flashing at my chimney, walls, and valleys \u2014 new or reused?\u201dWhy it matters: most leaks are flashing failures, and most premature roof failures trace to installation and flashing workmanship rather than materials (NRCA). Reused flashing is deferred leakage.
10. \u201cWhat happens if you find rotten decking \u2014 what does replacement cost per sheet?\u201dWhy it matters: decking surprises are the #1 mid-project upcharge. A pro prices it in the estimate; a bait bid prices it in your wallet later.

Which Questions Protect Your Wallet and Your Warranty?

Direct answerQuestions eleven through fifteen cover money and accountability: itemized pricing, payment schedule, warranty terms in writing, the change-order policy, and who owns cleanup and final inspection. Ask them now, because after signing you have no leverage left.

11. \u201cWill the estimate be itemized \u2014 labor, materials, accessories, permits, disposal \u2014 line by line?\u201dWhy it matters: itemization is how you compare three bids honestly, and how you know what you\u2019re actually buying.
12. \u201cWhat\u2019s the payment schedule \u2014 deposit, milestones, final payment?\u201dWhy it matters: modest deposit, progress payments, final payment after your walkthrough. Large upfront cash demands are the classic contractor failure signal.
13. \u201cWhat does your workmanship warranty cover, for how long, and is it transferable?\u201dWhy it matters: manufacturer warranties cover material defects; the labor warranty covers everything else \u2014 and it\u2019s only as real as the paper it\u2019s printed on.
14. \u201cWhat\u2019s your change-order policy if scope changes?\u201dWhy it matters: mid-project additions are normal; surprise invoices are not. Written change orders with prices before work continues \u2014 that\u2019s the professional standard.
15. \u201cWho handles cleanup, magnetic nail sweeps, and the final inspection \u2014 and when?\u201dWhy it matters: nails in the driveway and an unswept yard tell you everything about a crew\u2019s standards. The final walkthrough should happen against the itemized estimate, together.

\u201cAsk the questions before the contract, not after the leak. Every one of these answers is written down somewhere in a good company\u2019s office \u2014 if they have to invent it on your porch, keep looking.\u201d

Which Answers Should Send You Running?

Direct answerWalk away from assignment-of-benefits pressure, verbal-only warranties, full cash upfront, \u201cpermits aren\u2019t needed,\u201d today-only pricing, refusal to send insurer-verified certificates, and inability to name local recent references. Each answer below has one purpose: getting your signature before your questions finish.

Answers that should end the conversation

\u201cJust sign here and we\u2019ll handle your insurance entirely.\u201d \u2014 Assignment of benefits hands your claim rights to a stranger. Politely decline and call your insurer yourself.
\u201cOur warranty? Don\u2019t worry, we stand behind our work.\u201d \u2014 Verbal warranties are weather vanes; they point wherever the wind blows.
\u201cCash in full and we start Monday.\u201d \u2014 Payment schedules exist because contractors who hold all the money owe you nothing.
\u201cRoofing permits? Around here we skip that.\u201d \u2014 Now your unpermitted roof is your resale and inspection problem.
\u201cI can only hold this price until tonight.\u201d \u2014 Shingles don\u2019t expire in 24 hours; manipulation does.
\u201cI\u2019ll email you the insurance stuff later.\u201d \u2014 \u201cLater\u201d is where uninsured accidents live.
\u201cReferences? Sure \u2014 here\u2019s my brother-in-law\u2019s number.\u201d \u2014 You want addresses from the last twelve months, within driving distance, that you can see with your own eyes.

\u201cA company that dodges the easy questions will not improve after you sign. The sales pitch never gets more honest once the deposit clears.\u201d

How Do You Turn Their Answers Into a Confident Decision?

Direct answerAsk all fifteen questions of every company, score each answer 1\u20135 on the same sheet, weight the categories \u2014 credentials heaviest, price lightest \u2014 and let the totals choose. Then run one final gut check on communication, because how they answer questions is how they\u2019ll handle problems.

Scoring converts fifteen impressions into one decision. Copy this card for each company, fill it in the evening after each meeting while memory is fresh, and compare totals:

Category	Questions	Weight
Licensing & insurance	1, 2, 5	30%
Track record & locality	3, 4	20%
Materials & methods	6\u201310	20%
Money & warranty	11\u201314	20%
Cleanup & finish	15	10%

Notice the structure: credentials and track record carry half the weight, price appears only inside the itemized-estimate question, and cleanup carries a full category \u2014 because a crew\u2019s exit tells you everything about its standards. When two companies finish within a few points of each other, choose the one whose estimator explained answers patiently rather than the one who promised fastest. Fifteen questions asked calmly will protect your home for decades; that\u2019s a better return than any shingle upgrade on the market.

What Else Should Homeowners Ask Before Signing a Roofing Contract?

How many roofing companies should I contact before choosing?

Three is the professional standard: one quote tells you a price, two tell you a spread, and three tell you the market. Interview all three within the same two-to-three week window so material pricing and demand are comparable, and ask every company the same fifteen questions from this guide.

Is the cheapest roofing bid ever the right choice?

Rarely. The lowest bid almost always achieves its price by deleting scope — thinner underlayment, reused flashing, skipped ventilation work, or an asterisk on decking repairs. Compare bids at identical specifications; a genuinely competitive bid on full scope usually beats a bargain bid on reduced scope over the roof’s life.

Should I get everything from a roofing company in writing?

Yes — everything. Material brands and product lines, underlayment type, flashing plan, ventilation counts, decking pricing, payment schedule, warranty terms, cleanup, and disposal. If a promise isn’t in the contract, it doesn’t exist in year three when you need it.

How do I verify a roofer’s certification claims?

Don’t rely on a badge on the website. Major manufacturers publish locator tools listing certified contractors by name — check the company directly on GAF’s, Owens Corning’s, or CertainTeed’s official site. While you’re at it, verify the license on your state’s portal and request insurance certificates sent by the insurer.

Do I need to be home during the roofing work?

For the start and the final walkthrough, yes. A professional crew wants a decision-maker to confirm the scope at kickoff, protect valuables near vibration zones, and sign off at completion against the itemized estimate and warranty. Middle days rarely require your presence beyond availability by phone.
