Schenectady Post Office roof, Schenectady, Schenectady County, NY.
The roof flashing on the Schenectady Post office, constructed in phases during the first four decades of the 20th century, had developed failures in multiple locations. An associated problem was the failure of the anchors and flashing on the stone balustrade that surmounts the walls of the building on the street elevations. The problems had at their source the electrolytic reaction between various metals used in the construction of the roof and balustrade, and inappropriate detailing of the flashing. Reconstruction of the balustrade and new flashing details were proposed for this National Register Listed building. The new work followed the Standards set by the Secretary of the Interior.
