a copper product coated
with a tin-zinc alloy in
lieu of lead, satisfies
but the patina is slightly
different, and installation
can be more costly if
it involves a lot of details

In the 1990s, manufacturers began
coating copper roofing with lead,
which caused it to age to a gray color,
versus the green patina of untreated
copper. New York-based Revere Copper
Products Inc. offers a more eco-friendly
material coated with tin and zinc, which
stands up to the elements and offers a
similar gray hue. ❚❚ revere 800-448-

“As with most things in
life, you get what you
pay for, and slate roofing
is exponentially more
costly than asphalt shingle
roofing. Still, a slate roof
can last 60 to 150 years.
Compare that to maximum
30 years for asphalt.”
