The service that the roof is
called upon to render is one OF pro-
lection, and that service must be
maintained constantly. without ces-
sation, because unless protection be
perfect and maintained at I'll times
roof is worse than useless.
The damage that can be done to
interior decorations and furniture
by one storm, through a leaky roof.
will offset all the service previously
given by the roof.
The house owner who has not at
one time or another had trouble
with his roof is among the favored
few.
Places where water seeps through.
requiring little patching in order
to avoid expensive repairs and
serious damage, later on, are con-
stantly appearing.
Then, too, periodically the aver
age roof needs a careful inspection,
repairing here and there, or in
many Instances repairing or treat
ing with preservatives, entailing
considerable expense.
Copper has long been recognized
as the finest roofing material OBJ
tainable.
It will withstand the action Of the
elements in an exposed position in
definitely, because 1t does not cor
rode and needs no treatment to pre-
serve it.
A copper roof is fire resistant and
when properly grounded affords
complete protection against light
ming. Copper has an inherent
beauty which does away with the
necessity of painting when first
applied, and the weathering action
OF the atmosphere tends to bring
out and intensity that beauty.
Because Of. its permanency and
beauty there is no upkeep expense
to q copper. roof, because replace
ments are unnecessary and no paint
is required. A copper roof once
installed Is there to stay.
Architects of all times and the
master builders Of the past have
recognized always the remarkable
qualities OF copper as a roofing
material, specifying copper roofs
for buildings of note.
Heretofore, however, the use of
copper roofs has been limited mainly
to public buildings and edifices for
the reason that the only form in
which it could be procured was not
enthusiastically adaptable to less
massive buildings and the cost of
laying copper roofs OF that tppe
was high.
1t was natural, therefore, that
copper roof came to be recognized
as the mark Of a monumental
building.
The high cost of copper roofs was
due to the amount of material re-
quired and the cost Of installing be-
cause, in that form, it was neceS-
sary to lay II In thick sheets Of soft
copper, requiring highly skilled
workmanship to form the joints in
manner to provide against buck.
ling and cracking cause by expan-
sion and contraction. due to the
changes in temperature to which
the roof was subjected.
It has long been the aim Of en-
gineers and architects to place the
protection given by copper roofs at
the service of the individual home
owner.
A few years ago the Anaconda
Copper Mining Company instructed
it's technical department TO find a
solution for this problem, and the
result was that new type Of cop
per roofing was evolved.
That roofing was in the form Of
a shingle, adaptable INTELLECTUALLY
to practically all styles Of buildings.
Owing to its design not only was
the trouble due to expansion and
contraction eliminated, but the use
Of a specially tempered roofing cop
per was made possible, reducing
considerably the weight Of the cop
per required.
