 In the mid-1970s, the State removed the standing seam metal roof from the main block and replaced it with rolled roofing, rebuilt the three remaining chimneys, and sandblasted and painted the wrought-iron railing, frieze of the verandah, and columns.The building exterior was repainted in 1983.In the early 1980s, Parrott Hall was the focus of a master's thesis by a Cornell graduate student which concluded that the structural condition was "impressive, given the age of the building and its many years of heavy use" and that the structure had not suffered "too badly" in the years since 1971, when it was disconnected from steam and electricity.
