Contractor Vetting Guide

How to Choose a Roofing Contractor

Your roof is one of the most expensive components of your home. Choosing the wrong contractor can cost you thousands in repairs, void your warranty, or leave you with a roof that fails years before it should. This guide gives you the tools to vet any roofer before you sign.

20+ red flags, 30 questions to ask, state license verification links, scam alerts, and a printable vetting checklist — everything you need to make a confident decision.

Skip the vetting hassle — compare quotes from pre-vetted contractors

Why Choosing the Right Roofer Matters

A roof replacement is one of the largest single expenditures most homeowners will ever make, typically ranging from $8,000 to $50,000 depending on the size of the home and the materials chosen. Unlike a kitchen remodel or a bathroom update, a roof is a structural system that protects everything beneath it. When it fails, the consequences cascade: water intrusion, mold growth, insulation damage, drywall destruction, electrical hazards, and in severe cases, structural compromise.

The roofing industry, unfortunately, has a lower barrier to entry than most construction trades. In some states, anyone with a truck and a ladder can call themselves a roofer. The National Roofing Contractors Association estimates that complaints related to roofing contractors consistently rank among the top categories at state consumer protection offices. Storm events make the problem worse: after major hailstorms or hurricanes, an influx of out-of-town crews descend on affected areas, collect deposits, and perform substandard work — or vanish entirely.

The good news is that the vast majority of these problems are preventable with basic due diligence. The questions, red flags, and verification steps in this guide will help you distinguish reputable contractors from unreliable ones — and protect your investment for decades to come.

20+ Red Flags to Watch For

Any one of these should give you pause. Two or more together is a strong signal to walk away and get quotes elsewhere.

Communication Red Flags

Unsolicited door-to-door sales after a storm

Legitimate contractors rarely go door-to-door. Storm chasers target damaged neighborhoods to pressure homeowners into quick decisions.

High-pressure tactics or artificial urgency

"Sign today or this price expires" is a manipulation tactic. A fair quote should stand for at least 30 days.

Refuses to provide a written estimate

Verbal quotes are meaningless. Without a written estimate you have no basis for holding the contractor accountable.

Won't provide a physical business address

A P.O. box or no address at all means the contractor may disappear after cashing your check.

Uses a personal email instead of a business domain

While not always a dealbreaker, a Gmail or Yahoo address combined with other flags suggests a fly-by-night operation.

Avoids answering direct questions

A reputable contractor welcomes questions about process, timeline, and materials. Evasiveness signals something to hide.

Business Red Flags

No license or won't share their license number

Most states require contractor registration. Refusal to share a verifiable license number is an immediate disqualifier.

No proof of insurance or workers' compensation

If an uninsured worker is injured on your property, you may be held financially responsible.

Demands cash-only payment

Cash payments leave no paper trail for warranty disputes, tax reporting, or legal recourse.

Won't pull building permits

Permits ensure the work is inspected and code-compliant. Unpermitted work can void insurance and cause problems when selling your home.

No online presence or reviews

A company with zero web presence, no Google listing, and no reviews is difficult to vet and may not be around long-term.

Contract Red Flags

Vague scope of work in the contract

"Reroof as needed" is not a scope. The contract should specify tear-off, decking inspection, underlayment, material brand and model, flashing, ventilation, and cleanup.

No warranty details in writing

Both manufacturer and workmanship warranties must be documented in the contract with specific terms and durations.

Demands more than 30% upfront

Industry standard is 10-20% deposit. Large upfront payments give the contractor little incentive to complete quality work.

No change order process defined

Without a written change order process, "surprises" during the project become excuses for inflated bills.

Contract has no cancellation clause

Most states require a 3-day right of rescission for home improvement contracts. Its absence may violate consumer protection law.

Workmanship Red Flags

Offers to install over existing shingles without inspection

Layering over old shingles hides damaged decking. A proper job requires tear-off and inspection of the substrate.

Won't let you visit or see the work area

You own the property. Any contractor who restricts your access to active work is hiding substandard practices.

Rushing the job unreasonably

A 2,000 sqft roof replacement typically takes 1-3 days. Finishing in half a day likely means corners were cut.

No cleanup plan or dumpster on site

Nails, shingle debris, and packaging left behind are safety hazards. Professional crews include daily magnetic sweeps and debris removal.

Uses day laborers instead of a trained crew

Picking up workers from parking lots is a sign of an uninsured, unskilled operation. Ask about crew certifications and experience.

30 Questions to Ask Before Hiring a Roofer

Organized into five categories, these questions cover every aspect of a roofing project. A contractor who can answer all of them confidently and transparently is worth serious consideration. One who dodges, deflects, or gets irritated is telling you everything you need to know.

State	Licensing Authority	Level	Notes
Maine ME	Maine Dept. of Professional & Financial Regulation	Local	No state-level contractor license required; some municipalities require local registration.
New Hampshire NH	NH Joint Board of Licensure & Certification	Local	No general contractor license; local permits required. Verify local building department requirements.
Vermont VT	Vermont Secretary of State — Office of Professional Regulation	State	Residential contractors must register with the state. Registration number should be on all contracts.

Note: Licensing requirements can change. Always verify current requirements directly with the state or local authority. Some states that do not require state-level licensing may still require registration for home improvement contractors specifically. When in doubt, contact your local building department.

5 Common Roofing Scams and How to Spot Them

These are the most frequently reported scam patterns in the roofing industry. Understanding how they work is the best defense against falling victim to one.

The Storm Chaser Scam

Out-of-town crews flood a neighborhood after a hailstorm or hurricane, offering "free inspections" and pressuring homeowners to sign contracts on the spot. They collect deposits, do substandard work (or no work at all), then move on to the next disaster zone before warranty issues surface.

How to spot it

!Contractor arrived unsolicited after a weather event
!No local business address or phone number with a local area code
!Pressures you to sign before your insurance adjuster visits
!Offers to "pay your deductible" (this is insurance fraud)

Bait-and-Switch Pricing

A contractor offers an unusually low quote to win the job, then "discovers" problems once the old roof is torn off. They claim the decking needs replacement, more layers need removal, or additional materials are required — inflating the price well above competitor quotes you rejected.

How to spot it

!Quote is significantly lower than all other bids (30%+ below average)
!Estimate lacks specific material brands, quantities, or scope details
!Contract has no change order process or price ceiling
!Contractor discourages you from getting other quotes

Insurance Fraud Pressure

The contractor offers to "handle everything with your insurance company," inflates the damage claim, or coaches you to file a fraudulent claim. This is a felony that can result in policy cancellation, claim denial, and criminal charges — for you, not just the contractor.

How to spot it

!Contractor insists on meeting with your adjuster alone
!Offers to waive your deductible or pay it for you
!Pressures you to sign an Assignment of Benefits (AOB) before getting other quotes
!Claims they can "get insurance to cover" items not actually damaged

Unlicensed Sub-Contracting

You hire Company A, but Company A subcontracts the actual work to unlicensed, uninsured crews. If a worker is injured or the work is defective, Company A may claim they are not responsible, and the subcontractor has no insurance or assets to pursue.

How to spot it

!Workers on site cannot identify their employer or foreman
!Truck and equipment have no company branding
!Contract does not mention whether subcontractors will be used
!Contractor avoids questions about who will physically do the work

Material Downgrade

The contract specifies premium materials, but the contractor installs cheaper substitutes and pockets the difference. This is especially common with underlayment, flashing, and ventilation components that are hidden once the roof is complete.

How to spot it

!Contractor refuses to let you see material deliveries or packaging
!No material specification sheets provided before or during installation
!Finished roof looks different from samples or photos shown during the sales process
!Warranty registration paperwork does not match the materials specified in the contract

Frequently Asked Questions

Answers to the most common questions homeowners ask when choosing a roofing contractor.

How do I verify a roofing contractor's license?

Every state has a licensing authority where you can look up a contractor's license status online. Ask the contractor for their license number, then verify it through your state's licensing board website. We include direct links for 10 states in our State License Verification section above. A legitimate contractor will have no issue providing their license number upfront.

How much should I pay a roofer upfront?

Never pay more than 30% of the total project cost as a deposit. Reputable contractors typically ask for 10-20% upfront or a materials deposit. The remainder should be due upon satisfactory completion. Be wary of any contractor who demands full payment before work begins or asks for cash only. A structured payment schedule tied to project milestones is the industry standard.

What is the biggest red flag when hiring a roofer?

The single biggest red flag is a contractor who refuses to provide a detailed written estimate with a specific scope of work. Verbal quotes, vague proposals, or handshake deals leave you vulnerable to price changes, scope disputes, and substandard work. Every aspect of the project — materials, labor, timeline, warranties, cleanup, and payment terms — should be documented in writing before any work begins.

Should I get multiple roofing quotes?

Absolutely. Getting at least three quotes is essential for understanding fair market pricing in your area. However, comparing quotes is only useful when each quote covers the same scope of work — the same materials, the same tear-off process, the same warranty terms. A managed marketplace like RoofVista standardizes the scope so you are comparing apples to apples, not just bottom-line numbers.

How do I know if a roofing contractor has insurance?

Ask for a Certificate of Insurance (COI) that shows both general liability insurance (minimum $1 million) and workers' compensation coverage. Call the insurance company directly to confirm the policy is current and has not lapsed. If a contractor is uninsured and a worker is injured on your property, you could be held liable for medical expenses and lost wages.

What questions should I ask roofing references?

When speaking with references, ask: Was the project completed on time and on budget? Did the crew keep the work area clean? Were there any unexpected costs or change orders? How did the contractor handle problems that arose? Would you hire them again? Also ask how long ago the project was completed — a roof that looked great at installation may show issues within the first year or two.

Are storm chaser roofers always bad?

Not every out-of-town contractor is a scam, but the storm chaser model carries inherent risks. These contractors often lack local accountability, may not be around to honor warranty claims, and sometimes use high-pressure tactics to sign you up before you can compare options. If an out-of-town contractor approaches you after a storm, verify their licensing, insurance, and permanent business address before signing anything.

What warranty should a roofing contractor offer?

A reputable roofer should offer two types of warranty: a manufacturer warranty on the materials (typically 25-50 years for shingles, lifetime for premium materials) and a workmanship warranty on the installation (at least 5-10 years, with top contractors offering 15-25 years). Get both warranties in writing. Manufacturer warranties often require the contractor to be certified by the manufacturer — ask to see that certification.
