Common Residential & Commercial Roofing Scams in Sunnyvale
Be aware of these tactic used by unlicensed operators
Storm Chaser
Out-of-town crews swarm after bad weather, promise quick cheap fixes with 'leftover materials.' They take a big deposit, slap on temporary patches, or disappear entirely.
Upfront Payment Grab
Insist on full or half payment in cash before any work starts. After deposit, they ghost or do bare-minimum junk work.
Fake or Borrowed License
Flash a pocket card or use a buddy's credentials. Work fails inspection, or they skip codes causing leaks later.
Shoddy Materials Swap
Quote premium shingles but install cheap knockoffs. Roof granules shed fast, leaks start within a year.
How to Verify a Professional
Insurance
Request a certificate of insurance for general liability (at least $1M) and workers' compensation. It should name you as an additional insured. Call the insurer directly to verify coverage dates and limits—don't trust just a verbal promise.
Licensing
California roofers need a valid C-39 Roofing Contractor license. Check it free on the Contractors State License Board (CSLB) site at cslb.ca.gov. Search by license number, name, or business—ensure it's active and bonds are in place. For Sunnyvale jobs, confirm they pull local permits too.
