Copper Roofing
History. Copper has been used as a
roofing material for centuries. In America, the
use of copper in architecture has been steadily
growing since the time Paul Revere founded his
copper company. One of the oldest copper roofs
in America is Christ Church in Philadelphia,
built in 1787.
Style. Copper has
traditionally been favored by architects due to
its endurance and lasting beauty. Today copper
can be found in all types of architectural
applications including industrial, contemporary
and historical styles. Copper on a building
enhances the features, adds substance to the
architecture and value to the building.
Appearance. Copper is
best known for its patinated green color. After
installation, copper will turn from its shiny
salmon color through various shades of bronze
and hues of green before reaching its final
patina, the familiar green color. This process
can take 25-30 years.
Maintenance/Endurance.
Though copper has a higher cost initially,
properly installed copper roofing and flashings
can last a lifetime with little or no
maintenance. Copper is not only durable but
naturally resistant to fire, as well as
corrosion and oxidation from severe weather or
industrial conditions.
Materials/Planning.
The use of copper in architecture is a
complicated process. Copper is available in red
or plain, light green pre-patinated and pewterie
gray alloy coated, as well as many different
weights and tempers. The copper product selected
for a particular application must take into
careful consideration the structural
requirements, location, and conditions of the
building.
Environmental and Cost
Performance Objectives. Building a
sustainable world should include copper for its
contribution to environmental performance.
Copper is one of the most easily recycled metals
available. Nearly all the copper ever mined is
still in use today. Copper is totally
recyclable. Each year the amount of copper
recycled in the United States is equal to the
amount taken from newly mined ore. Copper is an
abundant natural resource. Only 12% of the
worldwide resource of copper has been mined
throughout history.
"Longevity, lasting a century or more copper
roofs do not need to be replaced. This longevity
reduces the need for new roofing materials and
prevents the waste generated from other old worn
roofing material. Across its life cycle—
from extraction to recycling—copper has a
minimal impact on energy consumption and natural
resources, while its use has an immensely
positive impact on energy efficiency, indoor air
quality and life cycle costs."
