Reports of scammers driving around in vehicles with fake roofing service decals have been brought to the attention of authorities, according to an October 16 news release by San Mateo County District Attorney Stephen Wagstaffe.

According to the district attorney’s office, the suspects offer “…free roof inspections or inexpensive repairs, but then intentionally damage homes and demand payment for repairs,” Wagstaffe said.

Wagstaffe said the scam has been reported in San Mateo, Belmont, Palo Alto, Albany and San Francisco.

The DA’s office warned residents that before agreeing to or paying for repairs, consumers can check to see if the contractor has a valid license at cslb.ca.gov.

Suspicious activity should be reported to the police.
