This invention relates to new and useful im
provements in a roofing material.
More particularly, the invention proposes the
construction of a new roofing material which is
superior to any roofing material heretofore made.
It is proposed to characterize the improved roof
ing material by the fact that it is a flexible sheet
like material and has an internal wire mesh or
perforated sheet layer.
The invention proposes a new and novel con
10
struction by which the roofing material is water
proof and heat proof.
It is proposed to provide asbestos fibre layers
against the faces of the wire layer. it is pro
posed to arrange water and heat proof sheets on 15
the outer faces of said asbestos layers spaced
from each other. It is proposed to provide an
asphaltum outer covering extending over said
water and heat proof sheets and through the
portion of the asbestos fibre layers which are lo 20
cated adjacent edges of adjacent sheets of said
Water and heat proof sheets.
It is proposed that said asphaltum material
also engage through the openings of the wire
mesh or perforated sheets in the areas indicated 25
in the previous paragraph.
The advantage of the new roof material re
sides in the fact that its heat proof and water
proof qualities are superior to similar materials
heretofore made.

Another object of the invention is the con
struction of a material as mentioned which is
simple and durable and which may be manufac
tured and sold at a reasonable cost.
For further comprehension of the invention, 35
and of the objects and advantages thereof, refer
ence will be had to the following description and
The areas I4@ are similar to the tufting of a
accompanying drawing, and to the appended
mattress in that they prevent layers from shift
ing. The improved roofing material makes a

invention are more particularly set forth.

vention.

Fig. 6 is a fragmentary perspective view 0f the
perforated sheet shown in Fig. 5.
The roofing material, according to this inven
tion, comprises a flexible sheet-like strip I0 which
preferably is wound into a roll, said strip I0 has
an internal wire mesh layer Il. Asbestos fibre
layers I2 are located against the faces of the
wire layer II. A plurality of spaced water and
heat proof sheets I3 are disposed against the
outer faces of said asbestos fibre layers. An
asphaltum covering I4 extends over said water
and heat proof sheets I3 and through the por~
tions of said asbestos fibre layers I2 at certain
areas thereof. More particularly, the asphaltum
cover I4 extends through the areas I4a which
are located between adjacent edges of adjacent
sheets I3 of said water and heat proof sheets I3.
The wire mesh layer II comprises the usual
wire mesh sheet made from interwoven warp and
weit wires. The asbestos fibre layers I2 are
formed from asbestos material which is picked
or spun into fibre-like pieces interengaged with
each other to have a plurality of air pockets t0
act as heat insulation pockets. The spaced Wa~
ter and heat proof sheets I3 preferably consist of
waterproofed cellulose film. This film is capable
of standing temperatures in excess to the melt
ing temperature of the outer covering of the
asphaltum material I4.
The water and heat proof sheets I3 protect
the asbestos fibre layers I2 from the asphaltum
I4 so that the asphaltum does not enter and clog
the pores of air pockets of the asbestos fibre
layers I2, except at the areas Illa. These areas
I4a are used to bind the asbestos fibre layers I2
and the wire mesh layer II together as a unit.
