Castle Rock, in Garrison, New York, was built by J. Morgan Slade in 1881 as the summer residence of former Illinois Central Railroad president William H. Osborn. It sits on the hill of the same name, looking down on the Hudson River 600 feet below. Visible from West Point across the river and NY 9D passing through Garrison, it has become one of the most recognizable man-made landmarks of the Hudson Highlands. In 1977 it was listed on the National Register of Historic Places.

Performed during 2010, this project included: the complete removal of, and subsequent re-installation of, a 130-year-old red slate roof; carpentry repairs; masonry repairs and re-pointing; and extensive copper work, including fabrication of many unique copper decorative roof elements.

We own our own scaffolding and lift equipment, which significantly reduced the cost and time of this project.

Integral box gutters had rotted off necessitating complete re-building.

We fabricated and installed 20 oz. copper liner with specially designed and formed brass tie rods to reduce possibility of gutter failure under heavy ice and snow loads.

After careful washing and inspection for soundness, all salvageable historic red slate shingles were re-installed.

Example of poor condition of roof as found and subsequent repairs.
