ALL ABOUT THE
COPPER SINGLE
IT'S USE is EXPECTED TO IN
CREASE CONSUMPTION OF
METAL EVERYWHERE
Original Cost is About Twice that
of Wooden Single, but Life is 10
Times as 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.
Harold Blake, superintendent of
the Washoe smeIter at Anaconda,
recently addressed the Butte cham
Der of commerce on this subject, in
part as follows:
1.-The copper single in place weighs
between 80 and 80 pounds per square
Goo square feet) and is probably
the lightest substantial material that
may be used for roofing purposes.
This weight compares with 200
pounds for a wooden shingle roof;
600 pounds for asbestos; $50 to 1000
pounds for slate, and 1900 to 1000
pounds for tile, for the same area.
I'm order to satisfy ourselves of
the merits of this single a 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 90 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 a drop of water had penetrated
through the copper shingle roof.
"In order hat 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
a permanent color ranging from a
very dark green to a brownish red,
which will satisfy the most esthetic
taste of any architect.
Question of Cost
with regard to cost, the copper
single has a material advantage
when compared with asbestos, slate {
or tile roofing, and costs originally
only about twice as much as the ord
mary wooden shingle. Not only this, I
but when the salvage value of the {
other materials is compared with that |
II the copper single, the advantage ]
S greatly in favor of copper. APP V
fortunately so per ZEN of the cost
# the root to you is represented by b
he value of the copper. For in d
lance, in comparing copper shingles s.
With the ordinary wooden shingles, d
1 the building is destroyed by fire "
within n year after erection, con- Il
Ter would be a great deal cheaper on "
of the salvage value. On the Il
'ther hand, if the building remains S,
landing until the roof has to be re-
laced, which in this territory is usu- h
lily necessary within a period of 10 c,
ears, copper, with a lifetime of al O
loo years, would again be the
as the cost of replacement
vould bring the total cost of the
yooden roof to a point greatly in J,
xcess of the original cost of the =
opper single roof at the time of y
first renewal. "
eve recommend the use of copper a.
for any roof having a pitch O.
{ at least two inches to the foot. -
hese shingles are applied to board ~
leathing, and no special preparation -
required to lay the roof, although W
e do recommend the use of a layer ~
slater's felt beneath the roofing. W.
o special skill is required to lay
lese shingles, and they can be laid nts
18th such rapidity that at least twice "
Ie area can be covered in a day with 70 -
'pper shingles as is normally COW ~
ed with wooden shingles. All other IN
'ofing materials, especially slate 81
tile, require considerably more Nv
Dor of a skilled nature to place III
EN-. In addition to the shingles,
valleys, hips, perges and an
outs will be supplied tt suit the ie'
nditions and to properly equip d
y building with facilities for she'd 90
ng water. ~
1.-THE copper shingle is not applica- uIS
to a flat roof, and to meet this o1
ed the Anaconda company is pro- 81
cling a copper sheet with timed eeMu
ges to facilitate soldering where -
, or raised joint construction is ne gu
,sary. Problem of expansion with Il
copper sheet, or even with the =
is of no more consequence III
this material than it is in any WI
Ter material now used for roofing
&C. -
THE company is intending to pack ~
shingles between layers of tha
per to keep them from being mar mo
l.. Sufficient shingles and copper ~
lis for one-half a square ESQ square uo e
IL will be packed in each box to We.
ilitate easy handling.
