Common Residential & Commercial Roofing Scams in Alviso

Be aware of these tactic used by unlicensed operators

🚫

Storm Chaser Scams

Contractors appear after storms or weather events, claiming to find 'hidden damage' that needs immediate repair. They often use scare tactics about water damage, mold, or structural issues to pressure you into signing contracts quickly.

🚫

Insurance Fraud Schemes

Roofers offer to handle your insurance claim and promise to cover your deductible or get you a 'free roof.' They may inflate damage estimates, create false damage, or pressure you to sign over insurance benefits.

🚫

Material Switching

Contractors quote premium materials but install cheaper, inferior products. They may use incorrect underlayment, wrong shingle types, or inadequate flashing that voids manufacturer warranties.

🚫

Deposit Disappearance

Contractors demand large upfront deposits (often 50% or more) for 'materials' then disappear or delay work indefinitely. Some may start minimal work to appear legitimate before vanishing.

🚫

Permit Avoidance

Contractors suggest skipping permits to 'save you money' or 'speed up the process.' This leaves you with unpermitted work that may not meet building codes and can cause problems when selling your property.

How to Verify a Professional

1

Insurance

Request certificates of insurance for both liability and workers' compensation. Contact the insurance provider directly to verify coverage is current and adequate. This protects you from liability if workers are injured on your property or if there's damage to your home during the project.

2

Licensing

Always verify California contractor's license through the CSLB (Contractors State License Board) website. Search by license number or business name to confirm active status, proper classification (C-39 for roofing), and check for any complaints or disciplinary actions. Never hire a roofer who cannot provide a valid California license number.

3

References

Ask for at least 3 recent local references from similar projects. Contact these references and ask about work quality, timeliness, communication, and whether the project stayed within budget. Visit completed projects if possible to inspect the workmanship firsthand.

Protection FAQs

What should I do if a roofer shows up at my door after a storm?

Politely decline any immediate offers and take their business card if they have one. Never allow them onto your roof for an 'inspection' without proper verification. Contact your insurance company first and get multiple estimates from established local roofing companies with verifiable licenses and local references.

How much deposit should I pay a roofing contractor in California?

California law limits deposits to $1,000 or 10% of the contract price, whichever is less. Legitimate contractors understand and follow this law. Be extremely wary of anyone asking for 50% or full payment upfront - this is a major red flag for potential scams.

What roofing license do I need to verify in California?

Roofing contractors in California must hold a C-39 license from the Contractors State License Board (CSLB). Always verify the license number on the CSLB website to confirm it's active, in good standing, and properly classified. Also check that the business name and address match what you've been given.

Are roofers who offer to handle my insurance claim trustworthy?

Be cautious of roofers who aggressively pursue handling your insurance claim. While some reputable companies offer this service, scammers often use it to commit insurance fraud. It's safest to work directly with your insurance adjuster and choose your own contractor. Never sign an Assignment of Benefits (AOB) form giving the contractor control of your insurance payments.

What should a proper roofing contract include?

A legitimate contract should include: complete company information with license number, detailed scope of work, exact materials specifications, start and completion dates, payment schedule tied to milestones, warranty information, permit responsibility, cleanup procedures, and procedures for change orders. Review everything carefully before signing.

How can I verify a roofer has proper insurance coverage?

Request certificates of insurance for both general liability and workers' compensation. Contact the insurance company directly (using the phone number from their website, not the certificate) to verify the policy is current and adequate. Ensure coverage amounts are sufficient for your project size and that you're listed as an additional insured during the work period.

What are signs of quality roofing workmanship?

Quality work includes: proper underlayment installation, correct flashing details around chimneys and vents, straight shingle lines, proper nail placement (not too high or too many), adequate ventilation, clean worksite daily, and thorough cleanup after completion. The roofer should provide before/after photos and walk you through the completed work.

How long should a roofing warranty last?

Reputable roofers typically offer workmanship warranties of 5-10 years, sometimes longer. Manufacturer warranties on materials can range from 25 years to lifetime, depending on the product. Ensure all warranty information is in writing and understand what's covered and any maintenance requirements to keep warranties valid.
