ALL ABOUT THE
COPPER SINGLE
IT'S USE Is EXPECTED no IN.
CREASE CONSUMPTION OF
METAL EVERYWHERE

Original Cost is About Twice that
Of Wooden shingle, but Life is 10
Times IS Long; Is Lighter Than
Wood and Costs Less than Asbes-
tos.
A great deal Of attention is be.
ing given the copper shingles, the
invention Of an Anaconda man,
and which is expected to increase
very materially the use Of copper.
the Washoe smelter 1t Anaconda,
recently addressed the Butte cham.
Der Of commerce on this subject, in
part Is follows:
1.-THE copper single in place weighs
between so and 80 pounds per square
GOO square feet) and is probably
the highest substantial material that
may be used for roofing purposes.
This weight compares with 200
pounds for wooden shingle roof;
900 pounds for asbestos; $50 to 1000
pounds for slate. and 1900 to 1000
pounds fer tile, for the same area.
I'm order to satisfy ourselves of
the merits Of this single portion
of a roof was put on one of our build
ings at Anaconda. This roof has been
subjected to tests with acids and
fumes from our plant and has with
stood both very successfully. In
order to test the waterproofing quail
ties of these shingles a spray from
a hose was played on this roof for
20 minutes, to represent the falling
Of rain, without the least sign Of
leakage. The full nozzle pressure
Of 40 pounds of water was then play
ed against the joints of the copper
shingles for a period of 10 minutes,
and after one hour this test was
again applied, with the result that
not drop of water had penetrated
through the copper shingle roof.
In order that artistic tempera-
ments may be satisfied, experiments
have also been carried on to produce
colored shingles. Through an oxida-
ton process these shingles are given
Ia permanent color ranging from a
very dark green to q brownish red,
which will satisfy the most esthetic
taste Of any architect.
Question of Cost
With regard to cost, the copper
single has q material advantage
when compared with asbestos, slate
or tile roofing, and costs originally
only about twice as much as the ord
mary wooden single. Not only this,
but when the salvage value of the
other materials is compared with that
of the copper single, the advantage
is greatly in favor of copper. APP
proximately so per cent of the cost
OF the roof to you is represented by
the value of the copper. For in
stance, in comparing copper shingles
with the ordinary wooden shingles,
If the building is destroyed by fire
within one year after erection, cop
per would be great deal cheaper on
account of the salvage value. On the
other hand, If the building remains
standing until the roof has to be re-
placed, which in this territory is usu-
ally necessary within a period of 10
years, copper, with a lifetime of at
least 100 years, would again be the
cheaper as the cost of replacement
would bring the total cost of the
wooden roof to q point greatly in
excess of the original cost of the
copper single roof at the time of
the first renewal.
I'VE recommend the use of copper
shingles for any roof having q pitch
of at least two inches to the foot.
These shingles are applied to board
sheathing, and no special preparation
Is required to lay the roof, although
We do recommend the use of q layer
of slater's felt beneath the roofing.
No special skill is required to lay
these shingles, and they can be laid
with such rapidly that at least twice
the area can be covered in day with
copper shingles as is normally COW
cred with wooden shingles. All other
roofing materials, especially slate
and tile. require considerably more
labor of skilled nature to place
them. In addition to the shingles,
Hastings, valleys, hips, verges and
spouts will be supplied to suit the
conditions and to properly equip
any building with facilities for she'd
ding water.
1.-THE copper single is not applica-
BILE to a flat roof, and to meet this
need the Anaconda company is pro-
ducing copper sheet with timed
edges to facilitate soldering where
lap or raised joint construction is ne
cessary. Problem of expansion with
the copper sheet, or even with the
single, is of no more consequence
in this material than it is in any
other material now used for roofing
purposes.
1.-The company is intending to pack
these shingles between layers Of
paper to keep them from being mar
red. Sufficient shingles and copper
nails for one-half a square $50 square
feet will be packed in each box to
facilitate easy handling.
Advantages Of Copper
Summarizing the advantages of
the copper single over other roof
ing materials now in use: They are
cheaper; they weigh considerably
less; they have salvage value of so
per cent. as against complete loss
with other roofing materials; they
