Metal roofing and metal wall
materials used my Metal Roofing New Jersey contribute to the
green building movement because of its high recycled content
and recyclability. Most metal used for metal roofing contain
at least 25% recycled content, which reduces both the cost
and environmental impact of creating new steel.
Because metal roofing contains
at least 25% recycled content it earns points in the United
States Green Building Council's Leadership in Energy and
Environment Design (LEED) program. When compared to other
building materials like concrete, steel looks even better as
concrete has a recycled content of only 3%. Other "green"
building products include domestically produced, flat rolled
aluminum which contains about 80% recycled materials and
copper roofing, which contains about 75% recycled materials.
The steel, aluminum, copper and
zinc used to make metal roofing panels is 100% recyclable
and metal roofs can be installed over flat roofs (although
not always recommended), which eliminates the need to remove
the existing roof and thus preserving valuable landfill
space. While steel is the most recycled roofing material
with an annual recycling rate that is currently above 70%,
its recovery rate is even higher at 90%. This means that the
new steel made with recycled material uses as little as 26%
of the amount of energy that would be required using new
materials only.
