6 Claims This invention relates in general to roof flashing, and in particular the invention is directed to, and it is the principal object to provide, a counter-flashing assembly of unique design.

Another object of the instant invention is to provide a counter-flashing assembly which is arranged so that the counter-flashing strip can be easily and quickly installed without employing screws or other similar connecting elements between the counter-fiashing strip and the reglet which the assembly includes. Mso the counterflashing assembly may be installed with a minimum of tools and without any special tools being required.

An additional object of the invention is to provide a counter-flashing assembly which is arranged to provide a rigid, water-tight and permanent engagement with, and protective cover for, upturned flashing as used for example between the roof deck and the parapet of a wall; the assembly being constructed and mounted in place so that it is impossible for the counter-flashing to separate from the reglet whereby the counterflashing will not loosen relative to the flashing, even after a long period of use.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efie'ctive for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a cross-sectional elevation of the joint between a roof deck and the parapet of a wall, shown with flexible roofing material upturned against the parapet as a flashing; the reglet being shown in place, but before assembly of the counter-flashing therewith.

Figure 2 is a cross-sectional elevation, showing the locating and securing molding and the counter-flashing as initially assembled, but before bending of the cap flange into holding engagement with the inwardly opening outwardly projecting channel of said counter-flashing.

Figure 3 is a cross-sectional elevation of the counter-flashing assembly after installation thereof is completed. a

Figure 4 is a cross-sectional elevation of a modification of the invention, showing the counter-flashing as initially positioned but before bending of the cap flange into engagement therewith.

Figure 5 is a cross-sectional elevation of the modified type of the invention after installation thereof is completed.

Referring now more particularly to the characters of reference on the drawings, and at present to the embodiment of the invention shown in Figs. 1-3 inclusive, the numeral I indicates the deck of a roof which is supported by ceiling joists 2 which are mounted at the ends in connection with a wall 3, the parapet 4 of which projects some distance above the roof deck I. The roof deck is covered with a flexible roofing material 5, which is turned up, as at 6, to cover the joint 1 between the roof deck and wall, and extends thereabove in face to face engagement with the parapet 4 as a flashing 8. The above arrangement is of course conventional, and the present invention relates to the counter-flashing assembly which is employed with the flashing 8 and which assembly comprises the following:

Adjacent but above the upper edge of flashing 8, the parapet is arranged with a counter-flashing locating and clamping reglet, indicated generally at 9. This locating and clamping reglet comprises a longitudinal strip of metal which is bent upon itself between the side edges to form a longitudinal socket or groove ID; the groove forming portion of reglet 9 being embedded in the parapet 4 from its inner face. The groove I0 extends inwardly at an upward slope as shown, and opens to said inner face of the parapet 4 in spaced relation to but a relatively short distance above the upper edge of flashing 8; the portion of reglet 9 below said opening extending downward as a shoulder flange I I which lies in face to face engagement with the parapet. The reglet 9 above the groove projects outwardly and initially in a horizontal plane as a cap flange I2, whose outer edge is bent downward as a longitudinal lip I3. The cap flange I2 immediately adjacent the parapet is creased or deformed longitudinally and upwardly as at I4, forming a corresponding downwardly opening, shallow groove I5 immediately adjacent but above the open end of groove The counter-flashing unit, which cooperates with the above described reglet, comprises a flat, longitudinally extending counter-flashing strip I6, having an outwardly rojecting inwardly opening channel I! formed integral therewith along its upper edge; said channel in its transverse plane being disposed at an upward and inward slope relative to said counter-flashing. The lower leg I8 of channel I! is of substantially greater length transversely of the channel than the upper leg [9 thereof, whereby when the counter-flashing I6 is abutted in face to face relation with the flashing 8, the channel [1 extends upward under cap flange I2 with the upper end of leg I9 seated in a groove II and the lower end of said leg projecting obliquely into the open end of groove I 0, and seats against the bottom thereof. A longitudinal foot 20 of substantial width extends into groove II) from the lower edge of leg l9 and engages the bottom of said groove.

In use, the reglet 9 is rigidly secured into the parapet at the time of erection of the latter.

Thereafter when th flashing 8 is in place, the counter-flashing unit is brought into position as shown in Fig. 2, and as above described. The cap flange I2 is subsequently bent downward for its full length and lies in face to face engagement atop channel H; the lip 13 frictionally engaging against leg l8 of the channel in holding relation and forcing the counter-flashing [6 into close sealing relation with the flashing 8. With the reglet thus engaged with the counterflashing unit, there is no need for separate securing elements therebetween, and the counterflashing cannot escape, and remains in watertight and permanent engagement with the fiashing 8.

In the embodiment shown in Figs. 4 and 5, the reglet includes an initially horizontal cap flange l2a, having a depending lip l3 a along its outer edge; said cap flange l2a being secured to the parapet 4a by an upstanding attachment plate 2| secured to the inner face of the parapet do by nails 22'; this form of the invention being especially designed for use in connection with structures wherein the parapet 4a is of wood or the like into which nails may be driven.

The counter-flashing unit here comprises a longitudinal counter-flashing strip lfia formed along its upper edge with an outwardly projectingLbut inwardly opening channel 23 of substantially V-shape in cross-section; said channel at its upper edge having a foot 24 which rests against the adjacent face of parapet 4a immediately below cap flange lZa.

Fig. l illustrates the positions of the reglet and the counter-flashing unit of this embodiment in the position occupied by the same when initially brought into assembly. Thereafter, the cap flange [2a. is bent downward into face to face engagement with the adjacent leg of channel 23, while the lip l3a is brought into close frictional engagement with the other and lower leg of said channel, forcefully and permanently securing the counter-flashing [Ba against the flashing 8a which rests against the parapet 4a.

While the invention in this specification is described as used inconnection with a roof-toparapet flashing, nevertheless, as is obvious, the invention may be used in connection with flashingsused for different purposes.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such! detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
