Abstract

Flashing comprising a sheet bent into a general ''''V'''' shape for disposition on a shingle and against the side to be flashed, said sheet having a cut-back and bent under lip portion at one end thereof for insertion under the top edge of the shingle, the lip portion forming a connection with the shingle without the use of fasteners.

[57] ABSTRACT Flashing comprising a sheet bent into a general V'i shape for disposition on a shingle and against the side to be flashed, said sheet having a cut-back and bent under lip portion at one end thereof for insertion under the top edge of the shingle, the lip portion forming a connection with the shingle without the use of fasteners.

1 Claim, 5 Drawing Figures FLASHING BACKGROUND OF THE INVENTION Flashing is customarily merely a series of short pieces of sheet metal bent up into a V shape having two leaves at right angles to each other and these are placed on successive shingles as the roof is shingled with an upstanding leaf closely associated with respect to the structure to which the flashing is to be applied. Nails are then ordinarily used to hold both the shingle and the flashing in position. When this nailing is used, it of course forms holes and the process is a relatively timeconsuming procedure, and it is the object of the present invention to provide flashing which needs no fasteners and can be laid down very rapidly.

SUMMARY OF THE INVENTION The improvement in flashing comprises a simple sheet of material which is bent into a general V shape preferably having an included obtuse angle so that when one leaf is placed upon a shingle and the joint arranged close to the surface to which the flashing is to be applied, the upstanding leaf will resiliently press against the surface so as to make it more watertight. At one end of the leaf applied to the shingle there is a cutback portion which is bent down and to the rear forming a lip to include the leading or top end of the respective shingle. When this is in position, the tap of a hammer will cause the lip to bend further closely embracing the edge of the shingle and thus forming a unit fastened in position without however any fastenings being used.

The next shingle is then placed upon the horizontal leaf of the new flashing and the process is repeated with another piece of flashing.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view illustrating the new flashmg;

FIG. 2 is a side edge view thereof illustrating the ap plication thereof to a shingle;

FIG. 3 is a view in end elevation looking in the direction of arrow 3 in FIG. 2;

FIG. 4 is a side view on a smaller scale illustrating the general application of the shingles and the flashing for instance to a roof, and

FIG. 5 is a view showing the application of the new flashing to shingles.

PREFERRED EMBODIMENT OF THE INVENTION In the present case the flashing comprises a sheet of material which is bent longitudinally along a line forming a leaf l2 and a leaf 14. The leaves 12 and l4 may be approximately of the same width but ordinarily that at 12 will be narrower than that at 14. The leaf at 14 is to be applied to an upright surface such as a dormer and the leaf at 12 is to be applied to the individual shingles as the roof is shingled.

Whereas the original blank was of rectangular form, the leaf 12 is cut as at 16 along the bend line 10 and a short forward lip portion 18 is then bent under as is clearly shown in FIG. 2. Assuming the first shingle as shown at 20 has been applied to the roof, its leading or upper edge 22 is bent up slightly and the lip 18 is tucked under it. Then the shingle is flattened down onto the roof and tapped with a hammer in the area which is indicated at 24, thus bending lip 18 to the dotted line position of FIG. 2. This makes the flashing and the shingle into a single unit, it being remembered that the leaf at 14 is tightly held against the vertical surface to which the flashing is applied.

Looking at FIG. 3 it will be seen that originally the leaf 14 is located at an obtuse angle with respect to leaf 12 so that the dotted line showing illustrates the position of leaf 14 when the flashing is installed. If the flashing is made of a resilient material such as aluminum or other suitable material, then the leaf 14 will bear against the surface to which the flashing is applied by its own inherent resilience making the same firmly connected with respect to the surface and also with respect to the shingle.

When shingle 20 and flashing l2, 14, etc. has been applied as above stated, another shingle 24 is laid upon leaf 12, the lip 18 is placed as previously described, and the leading end 26 of the flashing 14 is covered by the ensuing flashing leaf 14. This process is repeated with shingle 28 for instance and flashing 14" and lip 18" as before described in order to complete the flashing. When the flashing is no longer needed, as when the end of the dormer is arrived at, then the shingling is proceeded with as normal, and the course of flashing which is illustrated in FIG. 4 comes to its end.

The flashing is provided in lefts and rights, to accommodate any wall or surface to be flashed.

Iclaim:

l. The combination of shingles and flashing wherein the flashing comprises a series of members each adapted to lie flat on a shingle, and each flashing having a lip at one end thereof bent over the corresponding edge of the shingle, securing the flashing with respect to said shingle, the next shingle being applied to the flashing upon which the lip appears, and the next flashing being applied to the next shingle in the same way, the flashings overlapping each other and the shingles, and each flashing including a bent-up leaf member that bears on the object being flashed.

Claims

1. The combination of shingles and flashing wherein the flashing comprises a series of members each adapted to lie flat on a shingle, and each flashing having a lip at one end thereof bent over the corresponding edge of the shingle, securing the flashing with respect to said shingle, the next shingle being applied to the flashing upon which the lip appears, and the next flashing being applied to the next shingle in the same way, the flashings overlapping each other and the shingles, and each flashing including a bent-up leaf member that bears on the object being flashed.
