How to Choose a Columbus Roofing Contractor Without Getting Burned
The roofing industry has more than its share of fly-by-night operators, storm chasers, and pressure salespeople. Good contractors exist in Columbus — plenty of them. Here's how to find them and how to filter out the ones who'll disappear when something goes wrong.
The Baseline Credentials
Before you talk about quotes, verify these. It takes 15 minutes and eliminates 60% of the candidate pool.
Ohio Home Improvement Contractor (HIC) registration
Ohio requires HIC registration for residential remodeling contractors doing more than $25,000 in work. You can verify registration at the Ohio Secretary of State website or through the Ohio Department of Commerce. A legitimate contractor will provide their HIC number on their website, business cards, and quotes. If they can't provide it, they're not registered.
General liability insurance
Ask for a current Certificate of Insurance (COI). Look for: General Liability coverage of at least $1M per occurrence / $2M aggregate; current effective dates (not expired); the contractor's company named as the insured. Many reputable contractors will have the COI emailed directly from their insurance agent to you for verification.
Workers' compensation
Ohio requires employers to carry workers' comp through the Ohio Bureau of Workers' Compensation. This matters to you because if an uninsured contractor's worker gets hurt on your roof, your homeowner's insurance may be on the hook. Ask for their BWC coverage certificate.
Manufacturer certifications
Preferred / master / platinum certifications from GAF, Owens Corning, CertainTeed, and similar manufacturers mean the contractor has installed enough of that product, has completed training, and is held to standards by the manufacturer. These certifications also typically unlock enhanced warranties that non-certified installers can't offer.
BBB rating
Look up the contractor at bbb.org. Look at: rating (A or above), years in business, number of complaints, how complaints were resolved, and most importantly, whether the contractor responded to complaints. A contractor that ignores BBB complaints will ignore your complaints too.
Google reviews
Aggregated review sites (Google, Yelp, Angi) show patterns. A contractor with 200 five-star reviews and 5 detailed one-star reviews is more authentic than one with 50 flawless five-star reviews (which often look manufactured). Read the one-star reviews specifically — they tell you how the contractor handles problems.
The Questions That Separate Good From Average
After you've verified credentials, the conversation with the contractor is the next filter. These questions get past sales patter:
"How long has your company been at this physical address?"
A real contractor has a real Columbus address and has been there for years. A storm chaser can't answer this question because they set up seasonally.
"Will the same crew I meet today be the one installing my roof?"
Some contractors subcontract all actual work to day-labor crews. There's nothing automatically wrong with this, but the crew matters. Consistency between crews matters more. If the answer is "we have three crews and I can't tell you which will do your job," dig deeper.
"Who is the project manager and will they be on site?"
A good project is managed. A bad one is just "a crew shows up and does something." The project manager walks the job, handles change orders, catches mistakes, and is your main contact during the work.
"Can I talk to 3 of your recent customers?"
Not 3 they hand-picked as references — 3 from a recent project list. Most will give you the hand-picked list, which is fine for starters, but follow up with: "Can I drive by a project you completed last month?" If they can't, they don't have much recent work.
"What happens if you find deck damage once the old roof is off?"
The answer should be: they document it, stop and get your approval for the scope and cost, then proceed. The answer you don't want: "We just handle it and you pay when we're done." That's how homeowners end up with $5,000 bills they didn't authorize.
"Show me your contract template before you finish the quote."
A good contractor has a real written contract with clear scope, payment schedule, warranty terms, change order procedures, and dispute resolution. If the contract is a napkin or they "don't really use contracts," run.
"What's your warranty, and who honors it?"
Both the material warranty (manufacturer, typically) and the labor warranty (contractor) should be explicit. Labor warranties of 5-10 years are standard; 15-25 years from established contractors is better. Ask: "What happens to my labor warranty if you go out of business?" An honest answer is "it goes away" — most labor warranties aren't transferable. But knowing this tells you how much weight to give the warranty term.
"Why this price?"
A good contractor can explain their pricing. Not line-item dollars necessarily, but the logic: "We install with six nails per shingle, we use synthetic underlayment, we use ice-and-water at all penetrations, our labor warranty is 15 years. That's more than minimum code, and it costs a little more." That's a real answer. A contractor who says "well, this is what it costs" without explanation is either new or not paying attention.
Red Flags That Should End the Conversation
Door-knocking during peak storm season. Not all door-knockers are storm chasers, but most storm chasers door-knock. If they came to you, not the other way around, verify everything twice.
"Free inspection" that concludes with "significant damage." Always get a second opinion before filing a claim or signing a contract. A real damage finding should be easy to document and verify independently.
Pressure to sign today. "Today's price." "Crew availability." "Before prices go up." All sales tactics. The market doesn't move that fast.
Deductible waiver or rebate. Illegal in Ohio. Any contractor offering this is running an insurance fraud scheme or is ignorant of the law. Either way, not someone you want to work with.
Assignment of Benefits (AOB) contracts. These sign your insurance rights over to the contractor. Never sign one.
Very large upfront payment requests. 50%+ before materials are on-site is unusual. Reputable contractors have material credit with suppliers and don't need homeowner cash to buy supplies.
No physical address or cell-only contact. Real companies have offices and main phone lines.
Name that doesn't match insurance certificate or registration. If the contractor's business name on the quote is different from the name on their COI or HIC registration, you're dealing with a shell. Walk away.
Bids that are significantly below competitors with no explanation. Cheap quotes usually reflect cheap work. If one quote is 30% below two others on similar scope, the cheap quote is probably missing important line items.
Getting to Three Bids
The generally accepted practice is three bids. Here's how to get three that are worth comparing:
Start with recommendations: neighbors, friends, your real estate agent, and your home insurance agent are all good sources. Look for contractors who have done work for people you trust within the last 2-3 years.
Add 1-2 from verified online reviews: BBB accredited, A+ rated, in business 5+ years, with recent and detailed positive reviews.
Avoid: door-knockers, contractors who found you through storm activity, and anyone your neighbor's neighbor's cousin recommended without personal experience.
Once you have 3-5 candidates, apply the credential verification and the question filter. You'll usually end up with 2-3 that are worth a full site visit and quote.
The Site Visit
A proper estimate visit involves the contractor walking your roof (weather permitting), accessing your attic, measuring or confirming measurements, asking questions about your situation, and taking photos. A 10-minute visit isn't a real assessment — the contractor who spends 45 minutes is more likely to deliver an accurate quote.
The conversation should be about your specific home, your specific goals, and your specific timeline — not a sales pitch about why their company is great. If it feels like a pitch and not a diagnostic, that's a signal.
Making the Choice
Once you have 2-3 complete quotes from contractors you've verified, the decision comes down to three factors:
Fit of scope to your goals: Are they addressing the things you actually care about (longevity, warranty, ventilation, specific aesthetic)?
Value rather than price: Compare scope-normalized cost. The cheapest quote for identical scope isn't always the right answer — a mid-priced contractor with a 15-year labor warranty and a Platinum certification often outperforms a bargain installer over 20 years.
How you feel about the person you'll be working with: Your project manager will be in your life for a week or two. If they've been patient, clear, and knowledgeable through the sales process, they'll be that way through the work. If they've been slippery or pushy, that pattern will continue.
One last thing: The best way to verify a contractor is talk to someone they've done work for. Not a reference the contractor gave you — a neighbor, a friend, a Nextdoor post. Real word-of-mouth is worth more than any certification. Columbus is small enough that you can usually find someone within two degrees of separation who's worked with any given local contractor.
