The fire burned the roof and attic space above an oven at the bakery, located at 6528 Washington St., Munoa said. He said there might have been an electrical malfunction in a recessed ceiling light near the oven.

The bakery will be closed until the Napa County Environmental Management Department inspects the building, Munoa said.

The blaze damaged a specialized commercial oven that had been imported from Italy, Munoa said.
