Rockland County Psychiatric Center


The Rockland County Psychiatric Center was originally constructed during the 1920s and 1930s to provide residential treatment and rehabilitation for clients with mental illnesses. Although many of the buildings are no longer in use, the four main buildings, Buildings 57, 58, 59, and 60, are still in operation as residential facilities. The New York State Office of General Services (OGS) retained SGH to investigate and rehabilitate the historic clay tile roofing on these four buildings.

Based on the findings of our condition assessment, we determined that the roof was near the end of its service life and although water leakage was not widespread, some leakage occurred at roof perimeter conditions and penetrations. Buildings 58 and 60 also showed significant damage where copper flashings around roof hatches were deteriorated.

We recommended roof replacement and designed new clay tile roofs for Buildings 57 , 58, 59, and 60. The replacement was completed in two phases with the large main building, Building 57, completed as Phase I. Phase I work included:

  • Removal of the existing clay roof tiles
  • Repair of damaged sheathing
  • Installation of new roof underlayment and flashings
  • Replacement of roof battens and installation of new clay tiles
  • Blending of several different tile colors together to replicate the appearance of the original roof

Phase II includes roof repair and replacement for the remaining three buildings.
