Location
Albany, New York
Notables
National Register of Historic Places
HISTORIC LEGACY
The Cathedral’s original roof was constructed of standing seam sheet metal, which showed early signs of failure. In the 1870s, it was replaced with a slate roof and in 1938 the crenelated parapets were later removed.
PROJECT OVERVIEW
The removal of the gutters and crenelated parapets at the eaves allowed water to run over the clerestory walls and windows, accelerating deterioration. This project involved the replacement of the main upper roof over the nave, transepts and apse.
RESEARCH & DOCUMENTATION
The analysis of the roof replacement options ultimately concluded with the recommendation to install a sheet lead roof and gutters, along with reconstructing the crenelated stone parapets.
Lead roofing was selected for its visual similarity to the Cathedral’s early tin–plated roof and for its proven longevity. Consultation with lead roofing expert Stan Halls, from the United Kingdom, was conducted to ensure proper detailing and installation.
