How to Choose a Roofing Contractor: A Homeowner's Guide to Vetting, Questions, and Red Flags

Answer First: How Do You Choose a Roofing Contractor?

A good roofing contractor is licensed in your state, carries liability and workers' compensation insurance, has a verifiable local presence, provides a detailed written estimate, and stands behind their workmanship with a clear warranty. Choosing one is less about finding the cheapest bid and more about verifying that a company can legally, safely, and competently complete the work — and will still be reachable if a problem appears two years later.

The Federal Trade Commission (FTC) advises homeowners to get written estimates from multiple contractors, check references, and confirm that a contractor is licensed and insured before signing any home improvement contract. This guide turns that advice into a step-by-step vetting process you can follow.

The single most common mistake homeowners make is deciding under pressure. Storm-chasing contractors, same-day discounts, and high-pressure sales scripts are designed to make you sign before you have time to verify anything. The framework below is built to be used before you need it — or at minimum, before you sign.

For what a fair estimate should actually contain, see our roof replacement cost guide. For what happens during the project itself, see our roof replacement process guide.

Step 1: Verify Licensing

Most states require roofing contractors to hold a state-issued license. Licensing typically requires the contractor to pass a trade exam, demonstrate financial responsibility, and maintain a bond that provides the homeowner a limited avenue for recourse if the contractor abandons the work or fails to meet obligations.

What to ask for:

• The contractor's license number — and the name of the state licensing board that issued it.
• Verification that the license is current and active, not expired or suspended.

What to do with it:

Look up the license number on your state licensing board's website. In Tennessee, roofing contractors are regulated through the Department of Commerce and Insurance; in Alabama, general contractors are licensed through the Alabama Licensing Board for General Contractors. Most state boards offer a free online search tool where you can confirm the license is active and check for disciplinary history.

A license number printed on a business card is not verification. A license you have looked up and confirmed is.

Step 2: Confirm Insurance Coverage

A roofing contractor should carry two distinct types of insurance, and you should ask for certificates of insurance — not a verbal assurance that they are "fully insured."

Liability Insurance

General liability insurance covers property damage the contractor causes to your home during the project. If a roofer drops a bundle of shingles through your skylight, or a crew member damages siding with a ladder, liability insurance is what pays for the repair — not you.

Workers' Compensation Insurance

Workers' compensation covers medical costs and lost wages if a worker is injured on your property. This is the coverage homeowners most often overlook, and it is the one that creates the most exposure. If an uninsured worker is injured on your roof, you can be held liable in many states.

What to verify:

• The certificate lists your address as the certificate holder or additional insured for the project dates.
• Both liability and workers' compensation are listed and current.
• The coverage limits are adequate for a project of your roof's size.

If a contractor cannot produce a current certificate of insurance, that is a reason to stop — not a detail to work around.

Step 3: Evaluate Local Presence and Longevity

A contractor with a genuine local presence is more likely to be reachable after the project is finished, and is more invested in their reputation within the community. The FTC and Better Business Bureau both emphasize checking how long a company has operated and whether it has a physical address.

Indicators of a real local business:

• A physical street address — not only a P.O. box or a co-working space.
• A verifiable history in your region. A company that has operated under the same name for years has a track record you can check.
• Local references** — recent projects in your area you can drive by or call.
• A local phone number and staff who answer it.

Why this matters after the job:

Roofing warranties have two layers: the manufacturer's material warranty and the contractor's workmanship warranty. The manufacturer covers defects in the shingles themselves. The workmanship warranty — typically covering the installation labor for a defined period — is only as valuable as the contractor's ability and willingness to honor it. A contractor who has left the area, closed, or rebranded cannot honor a workmanship warranty. For how warranties fit into the broader replacement decision, see our roof repair vs. replacement guide.

Step 4: Require a Detailed Written Estimate

A verbal quote is not an estimate. The FTC recommends obtaining written estimates from at least three contractors so you can compare scope, not just price. Two estimates with very different prices often reflect different scope — not one contractor being cheaper.

A clear written estimate should identify the major project components:

If an estimate is vague — "replace roof, $X" — you cannot meaningfully compare it. Encourage the contractor to provide a written estimate that identifies these components so you can see what you are actually paying for. For a full breakdown of how each component is priced, see our roof replacement cost guide.

Step 5: Check Reputation — Carefully

Online reviews are useful, but they require the same skepticism as any other sales signal. The goal is to distinguish a genuine local reputation from manufactured or purchased reviews.

How to evaluate reviews responsibly:

• Volume and recency matter.** A contractor with a substantial body of reviews accumulated over years is harder to fabricate than one with a burst of five-star reviews posted in a single month.
• Read the substance, not just the stars.** Reviews that describe specific project details — the crew, the timeline, how problems were handled — are more informative than generic praise.
• Check the Better Business Bureau.** The BBB maintains business profiles that include complaint history, resolution status, and an accreditation rating. A BBB profile with unresolved complaints is a meaningful signal.
• Look for patterns in negative reviews.** A single unhappy customer is normal. A pattern of the same complaint — unpaid subcontractors, unfinished work, unreturned calls — is not.

The Roofing Press does not rank contractors or claim that any single company is "the best." Our Featured Contractor program highlights specific contractors serving defined geographic markets, but Featured Contractor status is not a ranking, award, or certification of superiority. It represents a transparent commercial relationship tied to a specific territory.

Step 6: Understand the Warranty Structure

Most homeowners assume "the roof is warrantied" as a single thing. In practice, a new roof typically carries two separate warranties, and understanding the difference prevents surprises later.

Manufacturer's Material Warranty

Issued by the company that made the shingles (or metal panel, tile, etc.). It covers defects in the material itself — manufacturing flaws that cause premature failure. Manufacturer warranties range from basic limited coverage to enhanced "non-prorated" coverage that may include labor for a set period. Enhanced warranty levels often require the contractor to be a certified installer of that manufacturer's system and to register the warranty.

Contractor's Workmanship Warranty

Provided by the roofing contractor. It covers the installation labor — problems caused by how the roof was installed, such as a flashing leak or improperly fastened shingles. Workmanship warranties vary widely: some contractors offer one year, others offer five or ten. This warranty is only as reliable as the contractor's longevity and willingness to stand behind the work.

What to confirm in writing:

• What each warranty covers and excludes.
• Whether the workmanship warranty is transferable to a new owner if you sell the home.
• Whether the manufacturer warranty requires regular maintenance or registration to remain valid.
• The process for filing a warranty claim — and who performs the repair.

Red Flags: When to Walk Away

Certain behaviors are reliable indicators that a contractor should not be hired, regardless of how attractive the price appears. The FTC specifically warns homeowners to be cautious of contractors who pressure them to sign immediately or who solicit door-to-door after storms.

High-Pressure Sales Tactics

• Same-day discounts** that expire if you do not sign on the spot. A legitimate contractor does not need you to decide in 20 minutes.
• "We have material left over from a job down the street"** — a common storm-chaser line used to create false urgency.
• Door-to-door solicitation immediately after a storm**, especially from crews with out-of-state plates and no local address.

Missing or Vague Documentation

• No license number, or a number that cannot be verified on the state board's website.
• No certificate of insurance, or reluctance to provide one.
• A "contract" that is a single line and a price, with no scope, no warranty terms, and no start/completion dates.
• No physical address, or an address that traces to a residential mailbox.

Payment Red Flags

• A demand for full payment up front before any work begins. Most reputable contractors require a deposit (often 10–30%) with progress payments, with the final payment due after completion and inspection.
• A request to pay in cash only with no receipt.
• A request to make the check out to an individual's name rather than the business name.
• A contractor who asks you to pull the permit yourself — sometimes done because the contractor is unlicensed and cannot pull one.

Insurance Steering

A contractor who insists you must use them because "the insurance company approved us" or who offers to "cover your deductible" is engaging in practices that can create legal and claim problems. Insurance adjusters evaluate damage; they do not assign you a contractor. For how the claim process actually works, see our roof insurance claim guide and our guide to what to do if a claim is denied.

Questions to Ask Before You Sign

A short, direct set of questions separates a contractor who is prepared from one who is not. Ask these in writing or in person, and expect clear answers:

1. What is your license number, and which state board issued it?
2. Can you provide a current certificate of insurance for both liability and workers' compensation?
3. How long have you operated under this business name in this area?
4. Can you provide recent local references I can contact?
5. Will the estimate itemize tear-off, decking, underlayment, flashing, ventilation, and permits?
6. What is the workmanship warranty period, and what does it cover?
7. What manufacturer warranty level will be registered, and are you a certified installer for that system?
8. Who pulls the permit, and is the fee included?
9. What is the payment schedule, and when is final payment due?
10. What is your process if concealed damage is found during tear-off?

A contractor who answers these clearly and patiently has earned consideration. One who deflects, becomes defensive, or cannot produce documentation has not.

How The Roofing Press Featured Contractor Program Fits

This publication exists to help homeowners make better roofing decisions before they contact a professional. When a homeowner is reading content relevant to a market where The Roofing Press has a Featured Contractor, the publication may introduce that contractor as a local professional serving that area.

Featured Contractors are associated with the specific geographic market they actually serve — a Middle Tennessee contractor does not appear on Alabama content, and neither appears on general national content simply because they exist in the system. Featured Contractor status is not a ranking, award, certification, or claim of superiority over other licensed contractors. It is a transparent commercial relationship tied to a defined territory.

If you are in Middle Tennessee, you can read the Terry Woodall Roofing Contractors profile. If you are in Central Alabama, you can read the Crimson Roofing AL profile. These profiles are editorial — they describe each company based on information from official sources, not paid endorsements presented as independent rankings.

For contractors interested in participating, see how the Featured Contractor program works.
