The Problem: This building was constructed in the late 1890's and the nearly
one-hundred year-old copper roofing had reached the end of its useful service life.
This was not a typical roofing design; the architect, working for a charitable foundation,
hired IRS to develop a working design, then provide the details and specifications
necessary to install the new copper roof intended to last another century.
-
Our Solution: Our background and experience, along with some research into
historical sheet metal fabrication aided in our ability develop a design that would meet the project
requirements. Upon review and acceptance of the design, we then developed the bidding documents facilitating
construction. Our design incorporated corrections and improvements to the original copper roofs design.
-
The Problem: The original copper panels installed on the dome were too large, causing fractures in
many of the panels as a result of normal thermal cycling. Over time, the number of panels exhibiting fractures
continued to escalate. The face fastening of fractured panels as a short term repair only served to escalate the
number of fractured panels.
-
Our Solution: The design of the new copper roof system incorporated panels sized to accept the expansion
and contraction resulting from normal thermal cycling without changing the roofs appearance.
This increased the labor costs, but addressed concerns that normal thermal cycling would once again
result in panel fractures, causing premature failure of the copper roof system.
