Roofing is consistently one of the most fraud-prone home improvement trades. The Federal Trade Commission cites roofing contractors among the top categories of home improvement complaints nationwide, with door-to-door solicitations after severe weather accounting for a disproportionate share of documented fraud. Knowing how to verify a roofer's credentials, what questions to ask before signing, and which contract terms are non-negotiable gives you the tools to hire safely and protect yourself financially.
Why Roofing Scams Are So Common (and How They Work)
Storm chasers are contractors who drive through neighborhoods after hail, wind, or tornado damage soliciting work door to door. They often operate out of state, carry no local license, accept large upfront payments, and disappear before completing the work or honoring any warranty claim.
The FTC documents several consistent patterns in roofing fraud: high-pressure same-day signing pressure ("this price is only good today"), requests for full payment upfront, refusal to provide a written contract, vague or missing warranty terms, and asking the homeowner to sign insurance assignment of benefit documents that transfer insurance settlement rights to the contractor.
Understanding these patterns is the first filter. A contractor who shows up at your door immediately after a storm and asks you to sign the same day should be treated as unverified until you have independently confirmed their license, insurance, and references.
Never Sign on the Spot After Storm Damage
Storm-chaser roofing contractors rely on urgency to bypass your judgment. The roof is not going to collapse in 24 hours while you verify credentials. Take three days to get multiple quotes from locally established contractors. The FTC documents that homeowners who sign same-day with door-to-door solicitors are far more likely to experience payment disputes, unfinished work, or disappearing contractors.
How to Verify a Roofer's License and Insurance
License verification is the first step for any contractor, not just roofers. The process takes about five minutes:
Step 1: Ask for the contractor's license number in writing. A legitimate contractor will provide it without hesitation. If they say they don't need one in your state, verify that claim independently with your state contractor licensing board before proceeding.
Step 2: Look up the license on your state licensing board's online portal. Search "[your state] contractor license lookup" to find the official portal. Verify that the license is active, in the correct trade category, and not subject to any disciplinary actions.
Step 3: Request a certificate of insurance. The contractor should provide a certificate of insurance (COI) showing general liability coverage and workers compensation coverage. The COI should be issued by the insurer, not typed up by the contractor. Call the insurer's verification line printed on the certificate to confirm coverage is current.
General liability insurance protects your property if the contractor causes damage. Workers compensation protects you from financial liability if a worker is injured on your roof. A roofer without workers compensation is a meaningful financial risk: in some states, if an uninsured worker is injured on your property, you as the homeowner can be held liable for medical costs.

How Many Roofing Quotes Should You Get?
Get at least three written, itemized quotes before selecting a contractor. Roofing quotes frequently vary by 20 to 40 percent for the same scope of work, according to contractor pricing surveys. That spread exists because contractors differ in material tier, overhead structure, and margin expectations.
Each quote should specify the same scope so you are comparing apples to apples. Ask each contractor to price the same shingle product or a comparable alternative, the same number of layers to tear off, the same underlayment and ice-and-water-shield specification, and the same cleanup and haul-away scope.
A quote that is 30 percent below the other two is worth examining carefully. It may reflect lower overhead, but it may also reflect a thinner product, a shorter labor warranty, or a contractor planning to cut corners on underlayment or flashing installation.
Ask Each Contractor for the Same Scope in Writing
To compare quotes accurately, provide each contractor with a written scope of work and ask them to bid against it. Include: tear-off (one or two layers), underlayment type (synthetic or felt), ice-and-water-shield coverage (eaves only vs full deck), shingle product tier (three-tab, dimensional, or premium), ridge cap specification, and flashing replacement at all penetrations. Without a common scope, comparing quotes is guesswork.
Questions to Ask a Roofing Contractor Before Signing
These questions should be asked of every contractor you consider before a contract is signed:
- Are you licensed in this state, and can you provide your license number for me to verify?
- Do you carry general liability and workers compensation insurance? Will you provide a certificate of insurance before work starts?
- Will you pull the permit for this job, and is the permit cost included in your quote?
- What shingle brand and product line is included in this quote? What is the manufacturer's warranty on that product?
- What is your workmanship warranty, and what does it cover?
- What happens if you discover damaged decking once the old shingles are removed? How is that priced, and will I see a written change order before work proceeds?
- How will you protect my property (landscaping, gutters, siding) during tear-off?
- What is your payment schedule? How much is due at signing, at start, and at completion?
What a Roofing Contract Must Include
A verbal agreement is not a contract. Before any roofing crew arrives, you should have a signed written contract that covers the following:
- Full scope of work: layers to be removed, underlayment spec, ice-and-water-shield coverage, flashing replacement, ridge cap, and haul-away
- Shingle brand, product line, and color
- Manufacturer's warranty term and type
- Contractor's workmanship warranty term and what it covers
- Who is responsible for pulling the permit (in most jurisdictions, the contractor pulls it)
- Payment schedule with dollar amounts, not percentages
- Start date and estimated completion date
- Change order process: any additional work requires a signed written change order before it begins
- What happens if decking damage is found: unit price per sheet of replacement decking
A contract that is vague on any of these points is an invitation for a dispute.
Red Flags When Hiring a Roofer
The following patterns are documented warning signs from the FTC and state consumer protection offices:
Demands full payment upfront. No legitimate contractor requires full payment before work begins. A deposit of 25 to 33 percent at signing is reasonable; more than that is a risk.
No written contract, or pressure to sign blank or incomplete documents. Never sign a document with blank fields. Every dollar amount, warranty term, and scope item should be filled in before your signature goes on the page.
No physical business address. A contractor who provides only a cell phone number and no verifiable local address is often a transient operation with no accountability.
Offers to waive your deductible. If a contractor offers to cover your insurance deductible, that is insurance fraud in most states. It means they are inflating the claim amount to compensate. This can expose you, not just the contractor, to legal liability.
Asks you to sign an assignment of benefits (AOB) immediately. An AOB transfers your insurance claim rights to the contractor. Before signing any AOB, consult your homeowner's insurance company directly.

Storm Chasers: The Specific Warning Signs After Severe Weather
The period immediately after a major storm -- hail, tornado, hurricane -- is when storm-chaser contractors flood affected neighborhoods. Distinguishing them from legitimate local contractors requires deliberate effort:
Legitimate local roofing contractors already have a backlog after a storm and will schedule an inspection appointment several days out. They will not pressure you to sign before they even inspect the roof. Storm chasers, by contrast, often show up with a pre-filled contract and a sense of manufactured urgency.
Ask where the company's physical office is located and verify it on a map. Ask how long they have operated in your metro area. Ask for three local references from jobs completed in the past two years, not testimonials from other states.
If your roof damage is insurance-related, call your homeowner's insurance company before signing anything with any contractor. Your insurer will send an adjuster to inspect the damage and provide an estimate. Use that estimate as a baseline for any contractor quote.
A full breakdown of what a roof replacement costs and what drives price variation is in Cost to Replace a Roof. If you are uncertain whether you need a full replacement or whether repair is sufficient, the comparison guide Roof Repair vs Replacement: How to Decide walks through the decision framework by damage type, age, and cost.
Frequently asked questions
Should I get three quotes for a roof replacement?
Yes. Three written, itemized quotes is the standard for any project over $1,000, and a roof replacement almost always qualifies. With fewer than three quotes you have no competitive baseline and no way to spot an outlier. Each quote should specify the shingle brand, product line, labor warranty length, and what happens if hidden decking damage is discovered mid-job.
Does a roofing contractor need to be licensed?
Licensing requirements vary by state. Some states require a specific roofing license, others require a general contractor license, and a few have no statewide requirement but leave licensing to municipalities. Search your state contractor licensing board online before hiring. In states with no requirement, verify the contractor carries general liability and workers compensation insurance as a minimum substitute for license vetting.
What is the difference between a manufacturer warranty and a workmanship warranty?
A manufacturer warranty covers defects in the shingle product itself and is tied to the brand, not the installer. A workmanship warranty covers the installation quality and is provided by the roofing contractor. These are separate documents. A workmanship warranty of five years or more from the contractor is a reasonable baseline for a full roof replacement.
Can I stay in my house during a roof replacement?
In most cases, yes. Roof replacement typically takes one to three days for a standard single-story home and does not require you to vacate. Expect significant noise during working hours. If you work from home, plan accordingly. Access to the attic hatch may be blocked temporarily, and pets or young children may be stressed by the activity overhead.
What percentage should I pay upfront for a roof job?
The Federal Trade Commission recommends never paying more than one-third of the total project cost before work begins. A contractor who demands 50 percent or more upfront before starting work is a red flag. A reasonable deposit covers material costs and mobilization. Final payment should be withheld until the job is inspected and any punch-list items are resolved.
Is door-to-door roofing always a scam?
Not always, but it is the single highest-risk scenario for roofing fraud. The FTC documents door-to-door roofing solicitation as the dominant delivery method for storm-chaser scams. If a contractor approaches you unsolicited after a storm, do not sign anything on the spot. Get their license number, verify it with your state board, and compare their quote against at least two other contractors you found independently.
What should a roofing contract include before I sign?
A complete roofing contract should specify the shingle brand and product line, the number of layers being removed, the underlayment and ice-and-water-shield specification, the labor warranty term, who pulls the permit, what happens if hidden decking damage is found and at what cost, the payment schedule, and the project start and completion dates.
