Common Residential & Commercial Roofing Scams in San Mateo

Be aware of these tactic used by unlicensed operators

🚫

Storm Chaser Scams

Contractors appear after storms claiming to be 'insurance specialists' who can handle your claim. They often overstate damage, pressure you to sign contracts, and disappear after receiving insurance payments.

🚫

Material Switching

Contractors quote premium materials but install cheaper, inferior products. They may show you quality samples but use different materials on your actual roof.

🚫

The 'Free Inspection' Trap

Scammers offer free inspections, then 'discover' extensive damage requiring immediate, expensive repairs. They may even create damage themselves to justify unnecessary work.

🚫

Permit Avoidance Scams

Contractors claim they can save you money by skipping permits, telling you 'it's just a repair' or 'the city won't notice.' This leaves you with unpermitted work that can cause insurance and resale problems.

How to Verify a Professional

1

Insurance

Request certificates of liability insurance and workers' compensation coverage. Verify coverage is current and adequate for your project size. Uninsured contractors put you at financial risk if accidents occur on your property.

2

Licensing

Always verify California contractor's license through the CSLB website. Legitimate roofers in San Mateo County must have a valid C-39 roofing license. Check for active status and look for any complaints or disciplinary actions.

3

References

Ask for recent local references in San Mateo County and actually contact them. Visit completed projects if possible. Check online reviews across multiple platforms, but beware of fake or purchased reviews.

Protection FAQs

What should I do if a roofer demands cash payment?

Never pay in cash. Legitimate contractors accept checks, credit cards, or bank transfers. Cash payments are untraceable and a major red flag. Always get receipts for any payments made.

How much deposit should I pay a roofing contractor?

In California, deposits should not exceed 10% of the total contract price or $1,000, whichever is less. Never pay the full amount upfront. Schedule payments tied to project milestones and completion.

What roofing license is required in San Mateo?

Roofing contractors need a C-39 license from the California Contractors State License Board. Verify the license is active, in good standing, and matches the business name. Check for any complaints or disciplinary actions.

Should I be concerned about 'too good to be true' pricing?

Yes. Extremely low bids often indicate cut corners, inferior materials, or hidden costs. Quality roofing materials and skilled labor have market rates. Get multiple quotes to understand reasonable pricing for your specific project.

What if a contractor says they don't need permits for my roof work?

This is a major red flag. Most roofing work in San Mateo requires permits. The contractor should handle permitting. Unpermitted work can void warranties, create insurance issues, and cause problems when selling your property.

How can I verify a roofer's insurance is legitimate?

Request certificates of insurance directly from their insurance company, not just copies from the contractor. Verify the policy is current and includes both liability coverage and workers' compensation. Call the insurance company to confirm coverage.
