Referring to the drawings by reference characters I have shown my invention as embodied in a roof flashing which is indicated generally at I0.

As shown the flashing is arranged in conjunction with a roof deck II and a parapet wall I2. The roof deck is shown as having covering of plastic material I3 thereon which may be any suitable preparation and may include asphalt, coal tar, or other material.

In the application the plastic material is preferbly first mopped upon the roof deck I I as shown in the drawings to a width substantially equal to that of the roof covering and then a layer of covering material such as paper I4 is placed upon the mopped material. This material I4 which I may be roof paper of suitable composition is provided with apertures I5 along one of its edges. These apertures I5 may be of suitable size, configuration and arrangement and as shown in the drawings are circular and are spaced uniformly apart. When the layer of paper It is laid upon the plastic material I3 which adheres to the roof deck II, the paper adheres to the plastic material and a portion of the plastic material passes through the apertures I5 and projects above the paper I4 as shown at A in Figs. 1 and 4 forming projections.

The roof deck is then mopped with plastic material for a distance corresponding to the width of the next layer of roofing to be laid and the edge of the previously laid layer is mopped as at I6. The projections A are simultaneously flattened. Also the lower face of the next layer is also mopped as at H (see Figs. 2 and 5). As shown in Fig. 3 the second layer is then swung upward and over so that the parts are brought into the position shown at It in Figs. 1 and 6 so that the second layer of paper is firmly held in place. The plastic material thus forms a continuous homogeneous mass from the roof deck I I through the apertures I5 and into contact with the lower face of the second layer of paper so that not only is a tight joint provided but the entire area is secured into one unitary'body.

The operation is continued until the parapet wall is reached at which point the edge I9 (as shown in Fig. 1) of the layer of paper adjoining the parapet wall is bent up after the parapet wall has been mopped with plastic as at 20. This plastic passes through the apertures I5 in this portion and on the outer surface a mopping of plastic 2| is placed. The plastic 2| extends under a base flashing angle member 22 which is thus secured to the mopped material 20 and 2|. The base flashing 22 includes apertures 23 through which the plastic 26 passes as indicated at B in Figs. 1 and 7. The outer surface of the upstanding part of the base flashing 22 is then covered with a flashing 24. This flashing 24 engages the moppedportion 26 of the parapet wall l2 and also engages the plastic 'material B which passes through the apertures 23 of the base flashing 22 so that the wall is held in one unit.

The flashing 24 includes a plurality of rows of spaced apertures 25 through which the plasticmaterial 26 passes as indicatedat C and overa portion of the upper section of the flashing 24 a mopping 25 of plastic material is placed. Over the plastic 25' on the flashing 24 at the upper part thereof and extending above the flashing I arrange a wire fabric 26 which is of mesh of such size that the'plastic material 26 will pass therethrough as also will the plastic material 25. As a result the fabric 26 is firmly embedded in the plastic thus holding all of the plastic projections 25 in place. After this is done a plastic covering 2'1 is arranged over the upper portion of the flashing 24 covering the projections and the mesh member 26 as shown in Fig. 1. As a result of this construction the roofing and flashing are held as one unit by the homogeneous interlocking projections A, B, and C formed by the plastic material which passes through the apertures. Nails 3!! may be employed to hold the parts assembled until the plastic sets.

In Fig. 11 I show a modification of my invention wherein shingles 46 are provided with apertures 4| at one end. The roof deck receives-a coating 42 of plastic material which passes through the apertures 4| and as each course of shingles is laid and is secured as by nails 43, the plastic material passes from the roof deck through the apertures 4| and engages the lower face of the portion of each shingle thereabove.

In Figs. 8, 9 and I have shown a modified type of flashing which is indicated generally at 50. As shown the flashing 56 is arranged in conjunction with a roof 5| and a parapet wall 52. The roof has a covering 53 which may be a composition roofing which has an up turned portion 54 engaging the parapet wall 52. This portion 54 is covered by a base flashing 54A which extends upwardly as at 54B..

My flashing as shown includes a metal strip 55. This strip 55 includes an upper portion 56, a lower portion 51 and'an intermediate portion 58. This intermediate portion comprises a plurality of layers of the strip preferably bent flat upon themselves as shown. The upper portion 56 is provided with'apertures 59 while the lower portion 51 is provided with apertures 66.

In use a coating of plastic is placed upon the parapet wall 52 and the strip 55 is also covered with plastic on the rear side thereof and the strip is then disposed immediately above the upper end of the portion 54B and is pushed in place thus forcing the plastic through the apertures 59 and 60 and forming projections or beads 6| and 62 which serve to hold the strip 55 in place. Nails 63 may be then driven through the strip 55 to serve to hold the parts united until the plastic sets. I

As shown, 'I may arrangea mesh member 65 having folded over portions 64 arranged beneath the folded over portions 58 previously described and thus locked. The mesh member includes an upwardly extending portion 65 which extends above the portion 56 and a downwardly extending portion 66 which extends below the portion 51 onto the up turned portion 543 of the roofing. The plastic projections 6| which pass through the apertures 59 also pass through the mesh portion 65 thus serving as an anchor and hold the parts in place. The projections 66 also pass through the mesh portion v66 serving to anchor the parts.

Beneath the folded over portions 58 I arrange a cover member 61 which may be of composition or a sheet of metal and which is securely held in place by the folded over strip and which extends downwardly over the mesh portion 66 and .as shown engages a plastic which is placed over the meslrfportion 66 as indicated at 68. Additional plastic is also placed in engagement with the upper portion 65 of the mesh member on the outer 'side thereof as at 69 and this plastic 69 extends through the mesh portion 65 into engagement with the parapet wall 52.

From the foregoing it will be apparent that the strip 55 is locked in place by the projections 59 and 60 and that these projections are also held in place by the mesh member 63 and it will be noted that the mesh member in turn is held in place by the plastic 68 which engages the mesh member and the upwardly extending portion 54B of the base flashing and also by the plastic 69 which engages the fabric and the parapet wall 52.

In Fig. 13 I show a modified form of metal strip. This strip indicated generally at 55a includes an upper portion 56a, a lower portion 51a and an intermediate portion 58a. This intermediate portion is formed similar to the intermediate portion 58 previously described and the strip shown in Fig. 13 differs from the strip previously described only in that apertures 59 triangular in shape are arranged with their bases reversed.

In Figs. 14 and I show another strip indicated generally at 56b which is similar to the strip! 55 previously described except that the upper and lower portions are provided with out struck tongues 59b which leave apertures 590 in the material. These tongues are shown as arranged staggered in two rows so that the tongues assume the position shown in Fig. 15. The use of the strip shown in Figs. 13, 14 and 15 is similar to that shown inconnection with Fig. 12.

From the foregoing description it will be apparent that I have invented a novel joint construction which is useful in the laying of roofs, in flashing, and which in fact may be employed generally wherever it is desired to unite overlapping layers of material and to secure the overlapping layers together as a unit and to secure them as a unit to the structure on which they are applied. With my invention it will be apparent that economy of manufacture and an assurance of a tight joint is secured.
