Questions That Matter
What to Actually Ask
These are the questions that separate real contractors from the rest. Skip the generic 'how long have you been in business' — these are the ones that reveal scope and standards.
Are you a manufacturer-certified contractor (GAF, DaVinci, etc.)?
Will my project qualify for an enhanced manufacturer warranty?
Do you do full tear-off or overlay?
What underlayment will you install?
Will you rebalance attic ventilation?
Are flashings new or reused?
Can I see a written, itemized scope and quote?
How is your workmanship covered after the project?

Red Flags
Walk Away If You See These
These aren't 'maybe concerning' — these are reasons to end the conversation and call someone else.
High-Pressure Same-Day Close
If they need you to sign today to lock the price, the price isn't real and neither is the urgency.
No Written Itemized Scope
A verbal price or a one-line quote is a setup for change-orders. Demand line items.
Cash-Only or Large Upfront Deposit
Standard practice is a small deposit to schedule, with the balance after work is complete and inspected.
No CSLB License Number
California requires roofing contractors to be licensed. No license = no project. Verify on the CSLB site.
No Manufacturer Certification
Without GAF or DaVinci certification, your project doesn't qualify for enhanced warranty coverage.
Door-Knock Sales Visits
Door-to-door storm-chaser pitches are almost always a bad sign. Real contractors don't need to door-knock.
What to Verify
Trust But Verify
Five quick verifications you can do in under 10 minutes — and absolutely should.
CSLB License Status
Search the contractor's license number on cslb.ca.gov. Confirm active status, no actions, and current bond.
Workers' Comp + Liability Insurance
Ask for current certificates. Without them, you're personally liable for crew injuries on your property.
Manufacturer Certification
Verify any manufacturer certifications a contractor claims (GAF or DaVinci) directly on the manufacturer's site.
Written Scope
Demand itemized scope and pricing in writing — not a one-line bid or verbal handshake.
