The board may at any time reexamine the properties on any roll, and upon request of an owner shall do so, and if it is found that the condition of such property or properties has changed so that justly such property should be eliminated from any rolls on file, or the base against which dollar rate is levied should be lowered, it shall so determine and make a supplemental roll with reference to such property or properties. When adopted by it, the board shall certify and file a copy thereof with the auditor, assessor and treasurer of the county wherein the property is situated, and such officer shall alter and change the existing rolls accordingly.
