Most bad roofing outcomes announce themselves before the contract is signed. The warning signs are consistent because the schemes are consistent: get money early, avoid accountability, and control the paperwork. Here are the seven red flags that matter most, why each one exists, and what it predicts.
Storm-chasing crews follow hail and hurricane damage from town to town. The pitch is speed: "We're already working in your neighborhood, we can get you on the schedule today."
Why it exists: after a major storm, demand for roofers spikes and homeowners are anxious. That gap is where out-of-area operators make their money.
What it predicts: the crew may be gone before problems show up. Warranty claims on a company with no local presence are close to worthless. If a door-knocker seems legitimate, slow the process down — ask for a license number, a local physical address, and local references, then verify all three before signing.
A deposit that covers scheduling and initial materials is normal. A demand for half or more of the contract price before any material lands on your property is not.
Why it exists: a large deposit shifts all the risk to you. Once the money moves, your leverage is gone.
What it predicts: at best, a contractor with cash-flow problems who is using your deposit to finish someone else's job. At worst, a deposit-and-disappear scheme. Structure payments around milestones — a modest amount to start, a payment when materials are delivered, and the balance only after the work passes your inspection. Some states also cap what a contractor can legally collect up front, so check your state's rules before paying.
Legitimate contractors put their license number on everything: contracts, estimates, trucks, business cards. A missing number is rarely an oversight.
Why it exists: unlicensed operators avoid putting a number in writing because you can check it.
What it predicts: no license usually means no verified insurance, no bond, and no recourse through the state board if things go wrong. Verify before you sign:
Also ask for a certificate of insurance sent directly from the contractor's insurer, not a photocopy from the contractor.
Some contractors lead with the claim, not the roof: "You won't pay anything, insurance covers it, we deal with the adjuster."
Why it exists: controlling the insurance claim means controlling the money. It also lets the contractor inflate scope in ways you may never see.
What it predicts: disputes with your insurer, inflated claims filed in your name, and in some cases offers to "cover your deductible" — which is insurance fraud in many states and puts you, not just the contractor, at legal risk. Hire a roofer to fix your roof. Keep the claim, the adjuster conversations, and the payments in your own hands.
An assignment of benefits (AOB) hands your insurance claim rights to the contractor. Once signed, the contractor can bill your insurer directly and, in some cases, sue the insurer in your name.
Why it exists: AOBs move the entire financial relationship away from you.
What it predicts: you lose visibility and control over your own claim, and disputes between the contractor and insurer can drag on with your roof — and your policy — caught in the middle. If a contractor makes an AOB a condition of doing the work, find another contractor. State rules on AOBs vary and have tightened in recent years, but the safest position is simple: don't sign one under sales pressure.
A phone number and a website are not a business. Check for a real, verifiable local address — not a P.O. box, not a residential mail drop.
Why it exists: an address is accountability. Operators who plan to be gone in six months don't lease offices or warehouses.
What it predicts: when a warranty issue surfaces in year two, you'll have no one to visit, serve, or pressure. Cross-check the address against the state license record where one exists (both the FL DBPR and CA CSLB lookups show the address of record).
Get at least three written bids. If one comes in far below the others, that's not a bargain — it's a question that needs an answer.
Why it exists: lowballing wins the signature. The margin gets recovered later through change orders, thinner materials, skipped underlayment and flashing details, or uninsured labor.
What it predicts: mid-job price increases, corner-cutting you can't see from the ground, or a crew whose workers' comp gap becomes your liability if someone gets hurt on your property. Compare bids line by line — materials, tear-off, disposal, permits, warranty terms — and make the low bidder explain exactly where the difference comes from.
Every flag on this list reduces to the same three moves: get paid before delivering, avoid anything verifiable, and take control of paperwork that should stay with you. A contractor who volunteers their license number, accepts milestone payments, carries verifiable insurance, and leaves your insurance claim alone has nothing to hide — and that's who should be on your roof.
Verify licenses at FL DBPR (myfloridalicense.com) or CA CSLB (cslb.ca.gov). In Texas, where no state roofing license exists, ask about the voluntary RCAT credential and demand insurance certificates directly from the insurer.
