Waterloo Library and Historical Society

The Waterloo Library Building (Waterloo, NY), was designed by the prestigious Albany firm Nichols & Brown in 1883, and “is a rare, intact example of Queen Anne Style institutional architecture. Utilized continuously as a library since its completion in 1883, the building has maintained interior and exterior architectural integrity to a high degree .” (National Register of Historic Places)

In 2002 the Waterloo Library and Historical Society, asked Bero Architecture to assist them in the analysis and subsequent restoration of their deteriorating slate roof and cresting.  The aged roof was suffering from delaminating original slates, incongruent slate repairs, asphalt shingle patching, staining, and missing cresting.


The Society chose to completely restore the roof and its distinctive cresting.  The existing slates were replaced with new Vermont Grey slates,  preserving the historic character of their building, and continuing the Society’s tradition of using high-quality and long-lasting materials.   The original slate had been in place for over 130 years.  The deteriorated roof cresting was carefully removed and restored off site. The terracotta crest tiles, used to cap the ridge of the roof, were cleaned and replaced along with supplemental reproductions from Boston Valley Terra Cotta. The decorative iron cresting with its striking arches and flower finials was stripped, repaired and repainted.

Bero Architecture also prepared an extensive CAP Architectural Assessment Report (2001) for this building, followed by a Roofing Condition Report (2002), The EPF Grant Roof Restoration project discussed here (2006-2007), and an Exterior Masonry Survey (2008).
