Roofing Estimate Red Flags: 10 Things to Check Before Signing

Ten estimate red flags

1. No measured roof area or scope diagram. Ask how quantity and waste were calculated.
2. Generic material descriptions. Require product, underlayment, flashing, ventilation, and accessory details.
3. No tear-off or disposal line. Confirm existing layers and haul-away.
4. Unlimited decking extras. Set unit rates and require your written approval before work.
5. No permit plan. Identify who applies, pays, and schedules inspection.
6. Pressure to sign immediately. Compare bids and read every agreement first.
7. Insurance guarantee. Coverage is the insurer’s decision under your policy.
8. Deductible waiver offer. You are generally responsible for your deductible; check state law and insurer rules.
9. Large upfront payment or cash-only demand. Ask for a clear milestone schedule and receipt.
10. Missing warranty and closeout terms. Get workmanship coverage, product warranty, cleanup, and final documentation in writing.

Clarify before you compare

Request a revised bid that identifies scope and exclusions. Compare the same material and assembly across contractors. Check required credentials and insurance. Verify references and complaint history independently. FTC guidance on avoiding home improvement scams describes warning signs such as high-pressure tactics.

Do not assume the lowest total is best or that a high total is unreasonable. Differences may reflect product quality, access, flashing, ventilation, safety, or omitted work. Our 12-point hiring checklist and how many bids to get offer a process.
