How to Choose a Roofing Contractor: 15-Point Checklist for 2026

Hiring a roofing contractor is one of the most important decisions you'll make as a homeowner. A quality roof protects your family, your belongings, and your home's structural integrity for decades. But the wrong contractor can leave you with shoddy workmanship, voided warranties, and thousands of dollars in problems. In this guide, we walk you through a comprehensive 15-point vetting process to ensure you hire a contractor who delivers excellent results at a fair price.

Why Choosing the Right Contractor Matters

The roofing industry, unfortunately, has more than its share of unlicensed operators, storm chasers, and fly-by-night companies. According to the National Roofing Contractors Association (NRCA), improper installation is the leading cause of premature roof failure—ahead of material defects, storms, or age. Even the best materials will fail if installed incorrectly.

The difference between a great contractor and a mediocre one isn't just quality—it's your warranty protection, insurance coverage in case of injury, code compliance, and resale value. Taking the time to properly vet your contractor upfront saves enormous headaches (and money) down the road.

The 15-Point Contractor Vetting Checklist

1. Verify State Licensing

Every state has different licensing requirements for roofing contractors. Some states require specific roofing licenses, while others include roofing under general contractor licenses.

What to do:: - Ask for the contractor's license number - Verify it on your state's licensing board website - Confirm the license is active and in good standing - Check that the license covers roofing work specifically

Red flag:: Any contractor who can't immediately provide a valid license number or says they don't need one. Even in states with minimal licensing requirements, legitimate contractors carry whatever credentials are required.

2. Confirm Insurance Coverage

This is non-negotiable. Your contractor must carry both general liability insurance and workers' compensation insurance.

General liability insurance protects your property if the contractor causes damage during the project (dropped tools, accidental water damage, etc.). Minimum coverage should be $1 million.

Workers' compensation insurance protects you if a worker is injured on your property. Without it, YOU could be liable for medical bills and lost wages.

What to do:: - Request a Certificate of Insurance (COI) - Call the insurance company directly to verify the policy is active - Ensure coverage dates span your project timeline - Confirm the policy limits are adequate ($1M+ liability, workers' comp per your state's requirements)

Red flag:: A contractor who hesitates to provide insurance documentation, offers to "save you money" by using uninsured subcontractors, or provides expired certificates.

3. Check Online Reviews and Ratings

Reviews are your window into what it's actually like to work with a contractor. Look beyond the star rating and read the details.

Where to check:: - RoofingPros — our verified contractor directory with authenticated reviews - Google Business Profile - Better Business Bureau (BBB) - Your state's contractor licensing board for complaints

What to look for:: - Consistent praise for communication, timeliness, and cleanup - How the company responds to negative reviews (professional responses show maturity) - Recent reviews (within the last 12 months) to confirm current quality - Specific project details that match your needs (roof type, material, scope)

Red flag:: Fewer than 10 reviews, no reviews in the past year, or multiple complaints about the same issues (leaks after installation, poor cleanup, no follow-up).

4. Request Detailed Written Estimates

A professional estimate should be a detailed document—not a scribbled number on a napkin. Get at least 3–5 written estimates to compare.

A proper estimate should include:: - Complete material specifications (brand, product line, color) - Underlayment type and ice/water shield details - Ventilation plan - Flashing details (drip edge, chimney, valleys, walls) - Tear-off and disposal scope - Timeline with start and completion dates - Payment schedule - Warranty information (both material and workmanship) - Permit responsibilities

Red flag:: Vague estimates that list only "roof replacement — $X,XXX" without material or scope details. These make it impossible to compare bids accurately and often lead to surprise charges.

5. Verify Local Presence

Legitimate roofing companies have established local roots. They have a physical office (not just a P.O. box), local phone numbers, and have been in the community for years.

What to verify:: - Physical business address (visit if possible) - Local phone number (not just a toll-free number) - Years in business at that location - Presence in local business directories and Chamber of Commerce

Red flag:: Companies that can only be reached by cell phone, have out-of-state area codes, or have just appeared in your area after a major storm. These "storm chasers" often do subpar work, collect payment, and disappear before problems surface.

6. Ask About Manufacturer Certifications

Top roofing manufacturers like GAF, CertainTeed, and Owens Corning offer certification programs that require contractors to meet higher standards for training, workmanship, and customer satisfaction.

Key certifications to look for:: - GAF Master Elite: Only 2% of contractors qualify; offers the strongest warranty options - CertainTeed SELECT ShingleMaster: Requires extensive training and proven track record - Owens Corning Preferred: Demonstrates commitment to quality installation

Why it matters:: Manufacturer-certified contractors can offer enhanced warranties (50-year or lifetime) that non-certified installers cannot. These warranties often cover both materials AND labor, whereas standard warranties only cover materials.

7. Understand the Warranty Structure

Roofing warranties are complex, and many homeowners don't understand what they're getting until it's too late.

Types of warranties:: - Material warranty (manufacturer): Covers defects in the roofing material itself. Standard coverage is 25–50 years, but many have prorated clauses that reduce coverage over time - Workmanship warranty (contractor): Covers installation errors. This is only as good as the contractor standing behind it—if they go out of business, the warranty is worthless - System warranty (enhanced): Available through manufacturer-certified contractors, these cover both materials and labor for 25–50 years with no proration

Questions to ask:: - What exactly does your workmanship warranty cover? - How long is the workmanship warranty? (Industry best: 10–25 years; minimum acceptable: 5 years) - Is the material warranty prorated or non-prorated? - Can you provide the full warranty documentation before we sign a contract?

8. Request References and Portfolio

Any reputable contractor should be able to provide: - 5–10 recent customer references (within the last 2 years) - Before-and-after photos of completed projects - Examples of similar work to your project (same material, similar home style)

What to ask references:: - Was the project completed on time and on budget? - How did the crew handle unexpected issues? - How was the cleanup? - Have you had any problems since completion? - Would you hire them again?

9. Confirm Permit Handling

A legitimate roofing project requires building permits in most jurisdictions. The contractor should pull permits as part of their service.

Why permits matter:: - Ensures the work is inspected for code compliance - Protects your homeowner's insurance coverage - Necessary for accurate home sales documentation - Required by most manufacturer warranties

Red flag:: A contractor who offers to skip the permit process to "save you money" or "speed things up." Un-permitted work can void your insurance, create legal liability, and cause problems when selling your home.

10. Evaluate Communication Quality

How a contractor communicates during the bidding phase is a strong indicator of how they'll communicate during your project.

Signs of good communication:: - Returns calls and emails within 24 hours - Arrives on time for estimates - Explains options clearly without being pushy - Provides a written timeline and keeps you updated - Has a designated project manager or point of contact

Red flag:: Days-long delays in responses, cancelling estimate appointments, inability to answer technical questions, or high-pressure sales tactics ("this price is only good today").

11. Review the Contract Thoroughly

Never sign a contract without reading every line. A proper roofing contract should include:

• Scope of work with specific materials and quantities
• Total cost with itemized breakdown
• Payment schedule (never more than 30% upfront; balance due upon completion and inspection)
• Start and completion dates with provisions for weather delays
• Change order process (how additional work is approved and priced)
• Cleanup responsibilities (daily cleanup, final magnetic nail sweep, dumpster handling)
• Lien waiver provisions (protecting you from subcontractor claims)
• Dispute resolution process

12. Check for Complaints and Legal Issues

Before signing, do a final background check: - Better Business Bureau: Check the company's rating and any filed complaints - State contractor board: Search for disciplinary actions or license violations - Court records: A quick search for lawsuits can reveal patterns of disputes - Consumer protection agencies: Your state's attorney general office may have complaint records

13. Assess the Crew and Subcontractors

Ask whether the contractor uses in-house crews or subcontractors: - In-house crews are generally preferred because the contractor has direct control over quality and training - Subcontractors can be excellent but add a layer of separation; ensure they're also licensed and insured - Ask if the crew foreman will be on-site throughout the project

14. Understand Payment Terms

Standard and reasonable payment structures: - Best: 10% deposit, progress payments tied to milestones, final payment upon completion and inspection - Acceptable: Up to 30% upfront, balance upon completion - Red flag: 50%+ upfront or full payment before work begins

Never pay cash. Always use check, credit card, or financing that provides documentation and consumer protection. Ensure all payments are made to the company (not an individual) and get receipts for everything.

15. Trust Your Instincts

After all the research and verification, trust your gut feeling. The right contractor will: - Make you feel comfortable and respected - Be transparent about costs, timelines, and potential issues - Not pressure you into quick decisions - Welcome your questions - Show genuine pride in their work

Questions to Ask Every Contractor

Before making your final decision, ask these essential questions:

1. How long have you been in business in this area?
2. Can I see proof of license and insurance?
3. Who will be the on-site supervisor for my project?
4. What happens if we discover hidden damage (rotted decking, etc.)?
5. How do you handle weather delays?
6. What is your cleanup process?
7. Can you provide a lien waiver from all subcontractors and material suppliers?
8. What is included in your workmanship warranty?
9. Will you obtain the necessary permits?
10. Can I keep a sample of the shingles/materials for future matching?

Common Scams to Avoid

The Storm Chaser Appears in your neighborhood after a major storm offering "free inspections." They may find (or fabricate) damage, push you to sign a contract immediately, and pressure you to assign your insurance benefits to them. Legitimate contractors don't operate this way.

The Lowball Bid An estimate that's 30–40% below competitors usually means corners will be cut: thinner underlayment, skipped ice shield, improper ventilation, or cheap flashing. You'll pay the difference—and more—in premature repairs.

The "Special Deal" Pressure "I can only hold this price until Friday" or "We have leftover materials from a job down the street." High-pressure time-limited offers are a hallmark of unprofessional operators. Quality contractors provide fair, consistent pricing without pressure tactics.

The No-Contract Handshake Any contractor who resists putting agreements in writing is someone to avoid, period. Verbal agreements provide zero protection when disputes arise.
