Application February 21, 1945,'Serial No. 579,048 5 Claims. 1 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 (Cl. 10S-6) 2 . 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 pitch and felt or paper. A coating 9 of asphalt 0r face oi the asphalt layer I3, the outer edge there pitch covers the upper surface of the roof. A 40 of abutting against the wall. Still another layer layer or ply I0 of felt or paper is laid over the or ply 22 of felt overlies the asphalt layer 2l and coating 9. Another layer or ply Il of asphalt or its inner edge is bent and curved downwardly di pitch covers the felt I0. Still another layer or rectly engaging the top layer I3 of asphalt with ply I2 of felt is superimposed upon the asphalt I I its outer edge abutting against the wall. The felt and this felt I2 is covered by a layer or ply I3 of 45 layer 22 is overlaid by a layer or ply 23 of asphalt asphalt or pitch. These layers comprise the main which extends over the inner edge of the felt ply portion of the roof and while live layers or plies ' 22 and onto the asphalt layer I3 and has its outer of asphalt and felt includingr the coating are illus edge abutting against the wall. It will be noted trated, it will be understood that any desired that the outer edges of the layers or plies all abut number of layers may be used. This roofing ma 50 against the inner surface of the wall se that a terial, comprising the layers of asphalt and felt cemented sealed moisture-proof joint is formed however, does not extend to the vertical wall 5 between the rooling and wall.; The downwardly but ends at a point remote therefrom as indi curved inner ends of the layers provide a slant cated at I4, leaving a space between the end of -ing surface for shedding the surface water and the material and the wall. 55 the enlarged inner edge of the topmost asphalt 2,405,325 3 layer enhances the binding of the rooñng at this point. The wall is exposed or uncovered up 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 isting work where a flashing ordinarily would be used, more easily and safely than flashings now in use. It eliminates the necessity for anchoring 4 standing wall connected thereto, a composite main portion of rooñng material including a facing that contains asphalt covering the area of said roof deck to a point remote from the wall, leaving a space between said main portion and said wall, and a border for connecting said main portion to the wall comprising a plurality of superimposed alternate layers of asphalt and felt interposed in the space between said main por devices for locking the dashing into the wall and also eliminates specially designed strips that are 10 tion and said wall, the outer margins of said layers having an edgewise abutting and cemented built into the wall to receive ñashings. The roof water-tight joint with said wall, the inner mar ing can be built up to a point much higher than is usual above horizontal surfaces with but very ~ gins of some of said layers slanting downwardly and engaging said main portion, the topmost slight additional expense because of the cheap ness of the asphalt and felt as compared with 15 layer being formed of asphalt and having its inner edge merging into said facing layer of metal. The specific embodiment of the invention asphalt on said main portion, said wall being is especially advantageous in patching existing or uncovered upwardly from the top surface of said old roofs, the flashing being removed and the border. rooñng material being cut away to leave edges in 4.
