Hiring a metal roofing contractor is not the same as hiring someone to replace asphalt shingles. Metal roofing systems whether standing seam, corrugated, or metal shingles — require specific installation knowledge, proper tooling, and an understanding of how metal behaves under Western North Carolina’s weather patterns. Freeze-thaw cycles, heavy rainfall, and seasonal temperature swings all affect how metal expands and contracts, and how it performs over decades.
The contractor you choose will determine whether you get 40–50 years of solid performance or a system that develops leaks, fastener failures, and voided warranties within the first five years. Most homeowners in Asheville and across Buncombe County spend significant time researching which metal product to buy, but not nearly enough time researching who will install it.
This checklist fixes that. Go through each point before committing to any metal roofing contractor for your home.
1. Verify Their NC Contractor License
In North Carolina, any roofing contractor performing projects valued at $30,000 or more is required to hold a general contractor’s license from the NC Licensing Board for General Contractors. You can verify a license in minutes at nclbgc.org. Search by company name or license number and confirm that the license is active, in good standing, and covers the appropriate work classification.
A metal roofing contractor without a valid NC license is a contractor you should walk away from, regardless of how competitive their price is. Unlicensed work creates legal exposure for you as a homeowner and gives you no recourse if something goes wrong.
2. Confirm Insurance Minimums
Before any crew sets foot on your roof, request certificates of insurance directly from the contractor’s insurance provider, not a photocopy from the contractor. You’re looking for two coverages:
General liability insurance at a minimum of $1 million per occurrence. This covers property damage and injury that occurs on your job site.
Workers’ compensation insurance covering all crew members. If a worker is injured on your property and the contractor doesn’t carry workers’ comp, you could be held liable.
Call the insurance provider listed on the certificate to verify the policy is active. A lapsed policy that shows up on the certificate looks just like a current one.
3. Check for Manufacturer Certifications
Metal roofing manufacturers, such as Metal Sales, McElroy Metal, and ATAS International, offer certified installer programs that train contractors on their products. Contractors who hold these certifications have demonstrated product knowledge, and they often unlock extended warranty options that uncertified installers cannot offer.
When a metal roofing contractor holds a manufacturer certification, it means the manufacturer trusts them enough to stand behind the work. For homeowners, that translates to longer warranty coverage and a more accountable installation process.
4. Review Their Portfolio — Minimum 20 Residential Metal Projects
Metal roofing experience is not transferable from asphalt shingle work. A contractor who has installed hundreds of shingle roofs but only a handful of metal systems is still a novice at metal. Standing seam installation in particular requires specialized tooling and techniques that only come from repetition.
Ask for a portfolio of completed residential metal roof installations, not commercial projects, not shingle work. You want to see homes similar to yours: similar pitch, similar complexity, similar neighborhood. Ask to see photos of finished work. Ask for job addresses you can drive by. A confident, experienced metal roofing contractor will have no hesitation sharing this information.

5. Read Reviews — Look for Patterns, Not Just Star Ratings
Star ratings on Google, Yelp, and the BBB tell you part of the story. Review content tells you more. When you’re evaluating a metal roofing contractor, read 15–20 reviews and look for consistent themes across multiple reviewers, not individual outliers in either direction.
Positive patterns to look for: Reviewers mentioning clear communication, job-site cleanliness, crews showing up when scheduled, and follow-through on warranties. Specific mentions of metal roofing work are more relevant than general roofing praise.
Red flag patterns: Multiple reviewers mentioning communication breakdowns after the contract was signed, unexpected charges not in the original estimate, or difficulty reaching the contractor after the job was complete.
BBB complaint history is also worth reviewing. A few resolved complaints over many years of business are normal. A pattern of unresolved complaints or complaints about workmanship specifically is a signal to look elsewhere.
6. Compare Warranties — 10+ Years on Workmanship
Metal roofing comes with two separate warranty layers: the manufacturer’s material warranty and the contractor’s workmanship warranty. Both matter, and neither replaces the other.
Manufacturer warranties cover defects in the metal product itself, coating failures, panel defects, and material degradation. These warranties range from 20 years on basic products to lifetime coverage on premium Kynar-coated systems. Manufacturer warranties are voided by improper installation, which is exactly why the contractor’s credentials matter so much.
Workmanship warranties cover installation-related issues, leaks caused by improper flashing, fastener failures, panel misalignment, and similar contractor errors. This is the warranty that protects you from the contractor’s mistakes.
A minimum of 10 years of workmanship is the standard to which contractors are held. Any contractor offering less than that is either not confident in their work or planning not to be around to back it up. Lane Roofing backs every installation with a 10-year workmanship warranty that commitment reflects confidence in the installation, not just a sales point.

7. Assess Communication Before You Sign Anything
How a metal roofing contractor communicates during the sales and estimation phase tells you a lot about how they’ll communicate once you’ve signed and the money has changed hands. The responsiveness test is simple: how long did it take them to return your initial call or email? Did they show up on time for the estimate? Did they answer your questions directly or deflect?
Contractors who are hard to reach before the job starts tend to be harder to reach once it’s underway. That becomes a problem when you have questions about material delivery, work schedule changes, or concerns about what you’re seeing on your roof.
During the estimate phase, evaluate whether the contractor is taking the time to understand your specific home, or if they’re treating you like a number. A contractor who walks your entire roof, asks about your priorities, and takes notes is more likely to deliver a quality installation than one who glances at the roof from the driveway and texts you a number.
8. Evaluate Estimate Detail — Itemized vs. Lump Sum
A professional metal roofing contractor will provide an itemized written estimate. A lump-sum quote with a single total and minimal detail is not an estimate — it’s a number you can’t evaluate or compare.
An itemized metal roofing estimate should include:
- Metal product name, gauge, and coating type
- Underlayment product and coverage
- Flashing materials and locations
- Fastening system details
- Tear-off and disposal costs (if applicable)
- Permit fees
- Labor costs broken out by scope
- Warranty terms in writing
If you receive two estimates and one is significantly lower than the other, an itemized breakdown will tell you exactly where the difference is coming from: cheaper materials, thinner gauge, excluded accessories, or skipped underlayment. Without that detail, you’re comparing numbers you can’t evaluate.

9. Verify Local References Within 50 Miles
A metal roofing contractor with genuine local experience in Western North Carolina will have references you can contact and job sites you can visit within a reasonable distance. Ask for 3–5 references from residential metal roof installations completed within the past two years, and ask specifically for references within 50 miles of your home.
Why local? Because contractors who work regularly in Asheville, Weaverville, Black Mountain, and surrounding communities understand the specific demands of mountain-area construction — steep pitches, challenging access, local building codes, and climate-specific installation requirements. A contractor who has done most of their work in Charlotte or Raleigh may not have meaningful experience with these conditions.
When you call references, ask more than just “were you happy with the work?” Ask whether the project finished on schedule, whether the estimate matched the final bill, whether they experienced any post-installation issues, and whether the contractor was responsive when they had questions after the job was complete.

10. Understand Payment Terms — Never More Than 30% Upfront
Legitimate metal roofing contractors do not require full payment upfront. The industry standard is a deposit at contract signing — typically 25–30% of the total project cost, with the balance due upon satisfactory completion.
A deposit that exceeds 30% of the project value is a warning sign. Contractors who ask for 50% or more upfront before materials are even ordered are either in financial trouble or operating in a way that leaves you exposed. If a contractor walks off the job after collecting a large deposit, your legal recovery options are limited.
Structure payments around project milestones where possible: an initial deposit, a progress payment upon delivery of materials and the tear-off is complete, and a final payment upon completion and inspection sign-off. Get these terms in writing in the contract, not just in conversation.
A reputable metal roofing contractor with a solid business and reliable cash flow has no reason to demand large upfront payments. They’ve done this before, and their materials suppliers and crews are not dependent on collecting your deposit before the job can move forward.
Frequently Asked Questions
How do I look up a roofing contractor’s NC license?
Go to nclbgc.org and use the license verification search. You can search by company name, individual name, or license number. The result will show whether the license is active, the classification it covers, and any disciplinary history.
What’s the difference between a roofing license and a general contractor’s license in NC?
North Carolina does not have a separate specialty license for roofing. Roofing work above the $30,000 threshold is subject to general contractor licensing requirements. Below that threshold, the work is unlicensed by law, but that doesn’t mean any contractor is qualified to do it; your due diligence on experience and insurance still applies.
Should I get multiple estimates for a metal roof installation?
Yes. Getting three estimates gives you a realistic price range and, more importantly, gives you the opportunity to evaluate how different contractors communicate, what they include in their scope, and how they respond to your questions. The lowest estimate is rarely the best value when materials and labor quality are taken into account.
The Bottom Line on Vetting a Metal Roofing Contractor
A metal roofing contractor who clears all 10 points on this checklist isn’t hard to find in the Asheville area, but they’re also not the cheapest option in the market. That’s by design. Experience, proper licensing, adequate insurance, manufacturer training, and a real workmanship warranty all come at a cost. That cost is reflected in the estimate, and it’s worth paying.
The alternative, hiring based on price alone, routinely produces roofs that fail before they should, warranties that don’t hold up, and contractors who are unreachable when problems surface. Given that a metal roof installation is a 40–50 year investment, the difference between a $2,000 savings on the front end and a $15,000 repair five years in isn’t hard math.
Use this checklist on every contractor you speak with. If they earn it on all 10 points, you’ve found a contractor worth hiring. If they can’t or won’t provide what the checklist requires, you’ve saved yourself a significant headache.
