This invention relates generally to roofing and
more particularly to improved construction for
connecting the foundation layers of a composition
or water proofed roof with a vertical wall, a
chimney, parapet and the like to prevent leaks.
An object of the present invention is to provide
a strong, durable and eiiicient weather-proof con
nection between the roof and the building walls.
Another Object is to provide roofing which is
cheap, easily laid and of considerable rigidity and
which is produced of ingredients which are avail
able at low prices.
Still another >object is to provide a construction
thatreliminates the necessity for anchoring de
vices, nails or the like.
A further object is to provide rooling that may
be successfully secured to a wall of concrete or
the like and may be readily connected to either a
new or an old wall.
The invention will be better understood from
the description thereof to follow taken in con
nection with the accompanying drawing in
which
Figure l is a fragmentary sectional viewtaken
through the vertical wall of a building and the
roof thereof showing the main rooñng material
connected to the wall by a construction embody
ing the present invention.
Figure 2 is a sectional view taken on the plane
of the line 2_2 of Figure 1.
Referring to the drawing, a vertical wall 5 of
concrete or any other suitable material is shown
formed with an integral roof deck B. A parapet 'I
of brick is built on top of the wall and on top
of the parapet is a coping 8.
The roof deck is covered with a composition
rooñng material preferably formed of a plurality
of superimposed layers or plies of asphalt or

.
The present invention is concerned with means
for preventing moisture from entering under said
roofing material from the parapet and contem
plates a construction formed of a plurality of su
perimposed layers or plies of asphalt, pitch or the
like and of felt, paper or the like. In accordance
with the present invention, a layer or ply I5 of as
phalt or pitch, which is similar to or may be actu
ally a continuation of the layer 9, is placed over
the supper surface of the concrete roof 6 in the
space between the end of the roofing material
and the wall 5.- A layer or ply I6 of felt or paper
is next laid or embedded flatwise over the asphalt
or pitch I5, the inner edge of the felt I 6 being
positioned adjacent the outer edge of the roofing
material and its outer edge abutting against the
-inner surface of the wall. Another layer` or ply
I1 of asphalt or pitch overlies the felt layer I 6,
said layer I'I extending across the edge I4 of the
20 main portion of the roof and directly merging
into. iai-"contacting with the upper 'layer I3 of
asphalt on the main po-rtion of the roof and hav
ing its outer edge abutting against the wall. A
strip I8 of felt or paper is laid on said layer I'I of
25 asphalt in overlapping relation to the joint be
tween the ply 9 of the main portion of the roof
and the ply I6 of the ñashing. Another layer I9
of asphalt overlies the strip I8 and merges into
the asphalt layer I'I at opposite edges of said
30 strip'. Another ply or layer 20 of felt overlies the
asphalt layers I'I and I9 and has its outer edge
abutting against the wall, and its inner edge
‘curved downwardly in overlapping relation to the
edge of said strip IB and into contact with the
asphalt layer I3. This layer 20 is topped by an
other layer or ply 2l of asphalt or pitch whose.
inner edge is bent around and over the inner edge
of layer 20 and engages directly on the top sur

wardly from the top surface of the layer 23.
The composite roofing herein described can be
used to good advantage in any place in new or ex
