How to Spot a Bad Roofer Before It's Too Late
Roofing has more scams than almost any other home service. A bad roofer can leave you with a leaking roof, voided warranty, code violations, and thousands in additional repair costs. Here are the red flags that separate legitimate contractors from the ones you should run from.
Red Flag #1: Door-to-Door Solicitation After a Storm
This is the #1 roofing scam in America. "Storm chasers" travel from city to city after severe weather, knock on doors, and offer free inspections. Their playbook:
- Point out "damage" that may not exist
- Pressure you to sign a contract immediately
- Do a quick, low-quality install
- Disappear before problems show up
What to do instead: After a storm, call your insurance company first, then get estimates from local roofers who've been in your community for 5+ years.
Red Flag #2: Demands Full Payment Upfront
Reputable roofers require a deposit of 10–30% with the balance due upon completion. Anyone demanding 50%+ or full payment before starting work is either undercapitalized (meaning they can't afford materials—a sign of financial trouble) or planning to take your money and run.
Red Flag #3: No Written Contract
Every roofing job should have a detailed written contract that includes:
- Scope of work (tear-off vs. overlay, material brand and type)
- Start and estimated completion dates
- Total cost with line-item breakdown
- Warranty terms (both labor and material)
- Who pulls the building permit
- How change orders are handled
- Payment schedule
If they push back on a written contract, walk away.
Red Flag #4: Offers to Waive Your Insurance Deductible
This is insurance fraud—and it's a felony in most states. If a roofer says "We'll cover your deductible" or "We'll adjust the invoice so insurance covers everything," they're asking you to participate in a crime. Legitimate roofers don't offer this.
Red Flag #5: No License, Insurance, or Physical Address
Every roofer should provide:
- State contractor's license (verify it online with your state licensing board)
- General liability insurance ($1 million+ minimum)
- Workers' compensation insurance (protects you if a worker falls)
- Physical business address (not just a P.O. box or cell phone)
If they can't produce these documents, they're not a legitimate business.
Red Flag #6: Unusually Low Bid
If one estimate is 30–40%+ below the others, something is wrong. Common reasons for lowball bids:
- Using inferior or counterfeit materials
- Skipping proper underlayment, ice shield, or flashing
- No permit (saving $200–$500 but voiding your warranty)
- Using uninsured labor
- Planning to "find problems" and increase the price mid-job
Red Flag #7: Pressures You to Sign Today
"This price is only good today" or "I have a crew available right now but not next week" are high-pressure tactics. Legitimate roofers understand this is a major decision and give you time to compare estimates. Never sign a contract the same day you get the estimate.
Red Flag #8: No Mention of Permits or Inspections
Roof replacements require building permits in virtually every municipality. The permit process ensures:
- Work meets building codes
- An independent inspector verifies quality
- The work is documented for future home sales and insurance claims
Skipping permits to save $200–$500 can void your manufacturer warranty, create code violations, and cause problems when you sell.
Red Flag #9: Won't Provide References
Any roofer who's been in business for more than a year should easily provide 5–10 references from recent customers. Actually call them. Ask about:
- Was the job completed on time and on budget?
- How did they handle any problems?
- Would you hire them again?
Red Flag #10: Recommends an Overlay Instead of Tear-Off
Overlays (installing new shingles over old) are sometimes appropriate, but dishonest roofers push them because they're faster and cheaper (for the roofer). Problems with overlays:
- They hide rotting decking and leaks
- They void most manufacturer warranties
- They add weight your roof structure may not support
- Most building codes allow only one layer of overlay
