How to Hire a Licensed Contractor for Roof Replacement: A Complete Checklist

Hiring the wrong roofer is one of the most expensive mistakes a homeowner can make — and it happens far more often than most people realize. The National Insurance Crime Bureau estimates that roofing fraud spikes significantly after major storms, with thousands of homeowners per year losing deposits to contractors who disappear or do defective work. A systematic approach to hiring protects both your home and your money.

What Should You Do Before You Call a Single Roofer?

Before contacting any contractors, understand what your state requires. Most states require roofers to hold a contractor license: California requires a C-39, Florida a CCC, Arizona an ROC license, and so on. Texas has no statewide roofing license but requires permits. Knowing your state's requirement means you will recognize immediately if a contractor gives you the wrong answer.

Start with your insurance company if the replacement is storm-related. Your insurer will issue a claim number and an adjuster's report. Do not let a contractor negotiate directly with your insurer before you understand the scope yourself. Some unscrupulous roofers inflate damage claims or commit insurance fraud, which can come back to you as the policyholder.

Get a minimum of three bids from licensed contractors. Bids should be based on the same scope (same material, same tear-off approach, same underlayment type) so they are comparable. If one bid is dramatically lower than the others, that is almost never a bargain — it usually indicates inferior materials, unlicensed subcontractors, or a contractor planning to cut corners.

What Questions Should You Ask Every Roofer?

Ask these questions before any contractor gives you a price:

• “What is your license number?”Write it down and look it up. In California, verify at cslb.ca.gov. In Florida, at myfloridalicense.com. In Arizona, at roc.az.gov. Do not accept a verbal assurance — verify the number yourself.
• “Can you provide a certificate of insurance?”You want general liability insurance (minimum $1 million) and workers' compensation insurance. Ask to be listed as the certificate holder. A contractor who does not carry workers' comp creates personal injury liability for you if a worker falls off your roof.
• “Will you pull the permit?” In most jurisdictions, a roofing permit is required. The permit triggers an inspection that protects you.
• “Are you a certified installer for any roofing manufacturer?” GAF, Owens Corning, CertainTeed, and other major manufacturers have certification programs. Certified installers can offer extended system warranties (Golden Pledge, System Plus) that unlicensed or non-certified contractors cannot.
• “What is your process for dealing with unexpected decking damage?” Rotted or damaged decking discovered during tear-off is common. The answer tells you whether the contractor has experience and will give you straightforward pricing for additional work.
• “Who are your local references?” Ask for references from your specific neighborhood or town, not just a general list. A contractor who has replaced roofs on your street for ten years is far more accountable than one who cannot produce a single local reference.

What Are the Biggest Red Flags Specific to Roofing?

Roofing has more fraud patterns than almost any other home improvement trade. Specific roofing red flags:

• Knocking on your door after a storm:Unsolicited visits after hail or wind storms are almost exclusively “storm chasers” — traveling crews that follow weather events. If a roofer shows up at your door claiming they “noticed damage,” assume the worst until proven otherwise.
• Offering to “handle your insurance”: Assignment of Benefits (AOB) fraud is rampant in roofing. Some contractors ask you to sign over your insurance benefits to them, giving them control of your claim. This can result in inflated claims, billing fraud, and policy complications. Never sign an AOB without consulting your insurance company.
• Demanding a very large deposit:For an average $10,000 roof replacement, an initial deposit of $1,000 to $1,500 is reasonable. Demanding $5,000 or more upfront — especially before any materials are ordered — is a red flag.
• Wanting to start “tomorrow”: Legitimate roofers have crews and schedules. A contractor who can start your roof the very next day may be a transient crew with no local commitments and no intention to stay.
• No written contract: Any roofer who is reluctant to put the scope, materials, price, and warranty in writing is protecting themselves at your expense. Never start work without a signed contract.

What Should a Roofing Contract Contain?

A complete roofing contract should include the contractor's license number, insurance information, a specific list of materials (shingle brand, model, and color; underlayment type; ice and water shield specification; ridge cap type), the warranty for workmanship (separate from the material warranty), permit responsibility, start and estimated completion dates, payment schedule tied to milestones, and procedure for handling additional damage discovered during tear-off.

Vague contracts (“will replace roof with shingles”) are designed to give the contractor flexibility to use the cheapest available materials. Specific contracts protect you.
