How to Vet a Roofer (Before a Storm Chaser Finds You)

Roofing draws more fly-by-night operators than any other home trade. After a hailstorm, out-of-town crews — "storm chasers" — canvass neighborhoods, knock on doors, offer to "handle your insurance," collect a deposit, and vanish or do shoddy work that fails the first hard rain. With a new roof running $5,900 to $46,000 depending on material and size, that's a lot of money on the line with a stranger who found you.

Vetting a roofer isn't complicated, but it's non-negotiable. The difference between a 30-year roof and a callback nightmare is mostly in who installs it and how carefully you checked them first. Here's the process.

Find roofers the right way — and get three quotes

Skip the door-knocker. Start with local, established roofers — companies with a permanent address, a track record in your area, and a phone number that connects to a real office. Neighbor referrals and roofing-supply houses are strong sources; suppliers know which crews buy quality material and pay their bills.

Get at least three written quotes on the same scope. Roofing bids vary widely, and three lets you spot both the lowball (missing scope, cutting corners) and the padded high bid. See the underlying math in Why You Should Always Get 3 Quotes, and check current pricing in our Roof Replacement Cost guide so you can sanity-check every number.

A storm chaser will pressure you to sign today, "before the price goes up" or "while we're in your neighborhood." A legitimate roofer is fine with you getting other bids. Time pressure is the tell.

Verify license, insurance, and manufacturer certification

Roofing is dangerous, high-liability work, so the credential check matters even more here.

• License. Many states license roofers specifically; others license them as general or specialty contractors. Look the company up on your state licensing board — a free public lookup shows license status, expiration, and complaints.
• General liability insurance. Covers damage to your home during the job (and roofs get damaged more than most trades — think a misstep through a skylight). Get the certificate directly from their insurer.
• Workers' compensation. This one is critical in roofing. Roofers fall. If a crew member is injured on your roof and the company has no workers' comp, you can be on the hook. Confirm active coverage before anyone climbs a ladder.
• Manufacturer certification. Major shingle manufacturers certify installers, and those certifications often unlock enhanced material warranties you can't get otherwise. Ask which manufacturers they're certified with.

Red flags specific to roofers

Watch for these — several are classic storm-chaser moves:

1. Door-to-door solicitation after a storm, especially out-of-state license plates.
2. Pressure to sign immediately or "today only" pricing.
3. "We'll handle your whole insurance claim for you" — a legitimate roofer works with your adjuster but doesn't run the claim or offer to "waive your deductible" (that last one is insurance fraud).
4. A large deposit or full payment upfront, or cash only.
5. No physical business address or a P.O. box only.
6. No written contract, or a vague one-line estimate.
7. No manufacturer certification for the shingle they're quoting.

These overlap with the universal 11 contractor red flags — if you see two or more, walk.

Reading the roofing estimate and contract

A real roofing estimate is specific. Before you sign, confirm it spells out:

• Tear-off vs. overlay. Are they removing the old shingles down to the deck, or laying over them? A full tear-off costs more but is the right call in most cases.
• Decking. What happens if they find rotten decking underneath? A good contract states a per-sheet price for replacement so you're not surprised.
• Underlayment and components. Synthetic underlayment, ice-and-water shield in valleys and eaves, new flashing, drip edge, and ridge venting — all specified.
• Shingle brand, line, and warranty. Exactly which product, and the manufacturer warranty term.
• Workmanship warranty. The roofer's own labor warranty (commonly a few years to a lifetime), separate from the material warranty.
• Cleanup and permits. Debris removal, magnetic nail sweep, and who pulls the permit (the roofer should).
• Change orders and lien waivers. How added scope gets priced in writing, and lien waivers confirming suppliers are paid.

Payment: never pay for a roof upfront

A roof goes up fast, so the payment schedule is short but the rules still hold. A reasonable deposit is 10–33% to cover materials; the balance is due on completion after you've inspected the work and it's passed any required inspection. Never pay in full before the job is done, and never pay cash. A roofer demanding the whole amount before the first shingle is a storm chaser's signature move. More on structuring this safely: Contractor Deposits & Payment Schedules.

Hold back a final portion until you've walked the job. On a completed roof you're checking for a clean, uniform shingle pattern, proper flashing at valleys and chimneys, straight ridge lines, and — critically — a thorough cleanup: no debris in the gutters, no leftover shingles in the yard, and a magnetic sweep of the lawn and driveway for stray roofing nails that can puncture tires and feet. Get a lien waiver confirming the roofer's suppliers were paid, so a materials yard can't lien your home for shingles you already paid for.

A quick roofer-vetting checklist

Before you sign, confirm you can check every box:

1. Local, established company with a real physical address — not a door-knocker or a P.O. box.
2. License verified on your state board, active and the correct class.
3. General liability and workers' comp confirmed by a certificate sent from their insurer.
4. Manufacturer certification for the shingle line you're buying, if you want the enhanced warranty.
5. Three written, itemized quotes you can actually compare.
6. Detailed contract — tear-off, decking price, underlayment, flashing, brand, both warranties, cleanup, permit.
7. No pressure to sign today and no offer to "waive your deductible."
8. Milestone payment schedule with a reasonable deposit and balance on completion.

Miss two or more, and keep looking. A roof is on your house for decades — an extra week of vetting is nothing against that.

FAQ

A roofer knocked on my door after the storm — should I use them? Be very cautious. The best roofers are usually booked and don't need to canvass door to door. Get their license and insurance, verify a local address, and get two other bids before committing.

Should I let a roofer "handle my insurance claim"? No. Work directly with your own insurance adjuster. A roofer can meet the adjuster and provide documentation, but anyone offering to run your claim or waive your deductible is a warning sign — the deductible waiver is fraud you'd be party to.

What's the difference between a material warranty and a workmanship warranty? The material warranty comes from the shingle manufacturer and covers defects in the product. The workmanship warranty comes from the roofer and covers installation errors. You want both, in writing.

How long should a roof replacement take? Most single-family asphalt roofs are torn off and re-shingled in one to three days. If a contractor says it'll take weeks with no clear reason, ask why.

Is the cheapest roofing bid ever the right choice? Only if the scope truly matches the others. A lowball often skips the tear-off, uses thinner shingles, or omits ice-and-water shield. Compare what's included, not just the total.
