How Sheet Metal Suppliers Help Restore the Nation’s Historic Roofs

History doesn’t just reside in books; it also manifests itself in architecture. Indeed, all states are home to historical buildings that serve as witnesses to the passing of time.

After hundreds of years, however, it’s not surprising that many such buildings require some upkeep to ensure their structural integrity. As it happens, roofs are one of the most commonly renovated parts of historical buildings because they serve the first line of defense against the elements.

Architectural firms chosen to undertake such renovations cannot choose just any material. Most leading sheet metal suppliers say copper remains the most ideal choice.


The Resilience of Copper

Copper has been used as a roofing material for centuries—and in many cases, it also lasts for centuries. In fact, this metal has been used in cathedrals and castles since medieval times, a testament to its unparalleled durability.

Furthermore, it’s one of the rare roofing materials that look better with age, similar to the finest wines. Exposure to the elements causes copper to oxidize, resulting in a patination. Over the years, copper roofs can don a variety of colors, ranging from pale blue to deep brown.

Successful Renovations

Given these properties, many centuries-old buildings inside and outside of America have been outfitted with copper roofs to herald the next chapter in their history.

The Massachusetts State House

The seat of government in the Bay State was constructed in 1731, making it the oldest structure still standing on Beacon Hill. Originally sporting a wood-shingle dome, the structure became the first building in North America to feature a cold-rolled copper roof. In 2012, this roof was overhauled to breathe new life to the stunning dome.

The Old Courthouse in St. Louis, MO

In 2014, this courthouse received a North American Copper in Architecture Award (NACIA) for the restoration of its historic copper roof, which was first installed in 1941. Despite the revamp, contractors made sure to design the new roof to stay true to the character of this historic building.

Library of Parliament in Ottawa

Since first opening in 1877, the Library of Parliament in Ottawa has sported a copper roof. In 2008, the roof was renovated in order to further extend the life—and beauty—of this signature feature.

Of course, renovating historic domes is no small task. It requires a considerable amount of high-quality copper to complete the project. As such, architectural firms and contractors should work with trusted companies that supply copper products, including customized square metal tubing and sheets.
