B'erg,-;San Francisco; Calif. Application January. 22,- 1951, Serial N0.- 635,231 1 Claim: (Cl.j108-'26);

The present invention relates to counter-fiashingg vsuch as-are used inthe constructiongof roofs to. prevent seepage ofwater along vertical 'ora-inclinedz-walls into thespace and counter-flashingcombination tthatis ,of" suchconstruction that itmay readily beinstalledtaround corners.

Inparticular, it is .anobject of the inventionto provide a -reglet and appertaining; ;counter-flashing; which; are .of such construction-that-they may readily be installedaround corners without need :to fit i separate. sections. thereof together.

Furthermore, it is an. object of my invention to provide -a 'simple,;eflective ..andtime-saving; method of installing reglets and counteraflashings abouticorners, without need of cutting them into sections-of. appropriate size and'fitting these sectionstogether.

These and other objects of the present invention ;will be apparent from the following description of the accompanying drawing whichiillustrates a'tpreferred embodiment thereof and wherein-- Figure 1 is a vertical section through a parapet wall provided withareglect--'and-'counter-flashing embodying myinvention;

Figure- 2 is afragmentaryperspectiveof a bla'nkfor a counter-flashing embodying my invention;

Figure 3 is a fragmentary perspective of a blank for a reglet embodying my invention;

Figures 4 and 5 are fragmentary perspectives of the counter-flashing and the reglet, respectively, resulting from the blanks shown in Figures 2 and 3; and

Figure 6 is a fragmentary perspective of a completed installation of a reglet and counter-flashing embodying my invention.

In Figure l the reference numeral 10 indicates a parapet wall on a roof 12 that is covered with layers of a suitable roofing material 14 which is bent upwardly and bears with its upwardly bent portion 15 against the inner face 16 of the parapet wall. To prevent moisture from seeping into the space between the inner face of the wall and the roofing material, a counter-flashing 18 is held over the edge portion of the roofing material by a reglet 20 that is secured to the parapet wall above the edge of the roofing material.

The reglet 20 is made of a suitable sheet material, such as sheets of galvanized copper or steel, and it has an upper portion 26 of L-shaped contour which is intended to form a compartment 28 with the face 16 of wall 10. It also has a support portion 30 in the form of a vertically disposed bar that lies flat against the face of wall 10 and is suitably secured to said wall, such as by means of 2,822,763 Patented Feb. 11, 1958 2., nails. onscrews shown-a t. .32tin Figural... The. portion 34 0f thegupperepart. 26 .of the-reglet which corresponds to the long bar of the Land, which vforms one; of the side; walls ofscompartment, 28, extends,- tparallel to the support "portionjflf and hence to; the face116 ,ofv wallv 10, when; the,areglet-tisrsecured..to. the. wall, and it hasa straight horizontally dispo sed-uupperv edge 36, overwhich is engaged a backwardlyturned flange-onlip 38 formed along the) upper :end: portion; of .thewcounterr-flashing :18

-to (suspend the; counterrflashing in its proper position.

The arrangement; is such that. the lip or flange 38. extends parallel .to and; lies closely adjacent. to,-.the main part .or apron:40 of the;counterrflashing which=isformed by a planar:=vertical1y;disposed .sheet "with no. bends. or curvatures. Along itsloweredgesaidfapron may be. provided with another cbackwardlyturned lip or flange 42 thatvis intended to bean against. the upwardly bent end'portion 15 ofi-the layers of-roofing material, and'which is of the same conformation! as the, upper flange 38 lying parallel :and closely adjacent;to'the apron, or mainbody 40 of the counter-flashing 18.

Formerly, ,whenreglets' were applied. to walls forming corners, it. was-necessaryto; cut them into sections of appropriate length'correspondingto the straight areas of the; wall, and tosecure -them,-separately to theseareas,

whichisagcumbersome andrcostly operation. Due to the simple construction of mynovel-reglet, .as above described, andthe parallel;dispositionof its portions 30 and 34, itis ,possible toainstall:the.-reglet around corners in a continuouszpiece without need to cut it .into separate sectionsof appropriate length. Having'ircference to Figures- 3 1and*5,-- ILuse, a reglet blank of appropriate length, and I markon its support portionw30'therlines along which the blank has to be bent to conformto the particular configuration-of the walljto which it;.is to be applied, as indicated at 43 and -44 in Figure 3. Them-whereverthe blank is-to be. bent to fit, around a projecting corner, I provide a simple straight. out or, incision 45 in its.wall portion34'and the-portion 46 correspondingto the short horizontal barof itsv-L-shaped contour; This may be done byanycraftsman of average-ability withpthewaid of a'hac-k saw or like instrument.- Where the-reglet'is to fit into a concavecorneror recess, however, I remove atbroad, slice from the. wall1portion 34 of the reglet as shown at 48 in Figurez3 and :cutz'a converging notch149 into portion 46. v I then -bend gthe v.blank;;along .the-bend lines 43 and 44 into the shape illustrated in Figure 5 to conform with the wall to which it is to be applied, hold it against the wall in its proper position and secure it to the wall by means of screws or nails 32 as previously described (Figure 1).

It remains now to install the counter-flashing and to suspend it in its appropriate position from the reglet. As in the case of the reglet, it was formerly necessary to cut the counter-flashing into appropriate sections corre sponding to the straight areas of the wall and to fit these sections together in a water tight manner, such as by mitering, whereupon the composite structure was aligned with the wall and suspended from the reglet. To cut the counter-flashing into sections of exactly predetermined length and to join the sections together at the proper angles is a time-consuming and cumbersome task which greatly increases the cost of the installation and which impairs the effectiveness and dependability of the resultant composite structure because the joints of the counterfiashing sections may not be fluid tight, or may become defective and pass moisture on to the end portion of the roofing material underneath after a relatively short period of practical use.

In accordance with my invention, I bend a piece of counter-flashing of the proper length in a manner conforming to the configuration of the wall to which it is to be applied. This is possible because the counterfiashing of the invention is made almost entirely of a flat sheet without bend and curvatures, as explained hereinbefore, and requires for suspension from the reglet nothing but the above-described backwardly turned straight flange 38 along its upper edge.

When preparing the counter-flashing for installation I mark upon the exposed face of its suspension flange 38 the places where it is to be bent outwardly or inwardly to conform with the configuration of the wall. Where the counter-flashing is to be turned outwardly to conform with a concave corner or recess, I provide a simple vertically extending straight incision in the flange 38 as shown at 50 in Figure -2, and where it is to be turned inwardly to fit around a projecting corner, I provide a straight vertically extending incision 52 of substantial width, lest the edges of the incision strike against each other and obstruct further bending during the subsequent bending operation. If the' lower edge of the counterflashing is provided with a flange or lip 42, as shown in Figures 1, 2 and 4, I provide incisions 50 and 52' in places in vertical alignment with the incisions 50 and 52 in the upper flange 38, as shown in Figure 2. I then bend the counter-flashing into the required-shape'along vertical bend lines 54 and 56 determined by the incisions 50, 50 and 52, 52 respectively, as illustrated in Figure 4.

After I have bent the counter-flashing in the described manner, I fit it against the reglet 20, drop its flange 38 over the upper edge 36 of the reglet structure and press it down into position until the hight portion of flange 38 bears against the straight upper edge 36 of the reglet structure, and its lower flange 42 bears against the upturned part 15 of the roofing material 14(Figures 1 and 6). The counter-flashing may now be secured in its proper position by means of screws 53 that are engaged in aligned apertures 54 and 56 provided in the upper edge portion of its apron 40 and its flange 38 and in apertures 58 that may be punched into the intermediate wall portion 30 of the reglet as shown in Figure 1. With the counter-flashing properly engaged over the edge 36 of reglet 20 and secured in position by the screws, a suitable moisture-excluding compound is packed into the compartment 28 between the outer face of wall 10 and the flange 38 of counter-flashing 18, which can readily be done since the compartment is open at the top. Above compartment 28 the compound is preferably banked into a slope that slants upwardly toward and into contact with the wall 10 as shown at 60 in Figure 1.

The resultant installation is dependably water-tight since the counter-flashing is a continual piece of metal sheet without joint or seam that might become defective (Figure 6), and since the installation of reglet and counter-flashing in accordance with my invention does not re quire that either the reglet or the counter-flashing be cut into sections which have to be fitted together in their proper relative positions, the method of installing reglets and counter-flashings in accordance with my invention saves a very substantial part of the time and labor that was formerly necessary for the installation of reglets and counter-flashings on walls of irregular configuration.

While I have explained my invention with theaid of a particular embodiment thereof, it will be understood that the invention is not limited to the specific constructional details shown and described which may be departed from, without departing from the scope and spirit of my invention.

I claim:

A flashing installation for walls forming corners comprising a reglet of sheet metal having a support portion adapted to lie flat against the wall and a wall portion disposed parallel to and above said support portion in a different vertical plane and having a straight horizontally disposed upper edge, said wall portion having vertical incisions at points corresponding to the corners in said wall and said reglet being bent to conform to the configuration of the wall along vertical lines determined by said incisions, a continual counter-flashing formed by a metal sheet having its upper edge portion turned backwardly upon itself to form a retaining flange extending parallel to the remaining part of said sheet, vertical incisions provided in said flange at points corresponding to the corners in said wall, said counter-flashing being bent along vertical lines determined by said incisions to conform to the configuration of the wall and vthe flange of said counterflashing being engaged over the upper edge of the wall portion of said reglet; and a plastic compound packed intothe space between the wall and the engaged flange of said counter-flashing, said compound being banked up to form a slope slanting from said flange upwardly into contact with the face of the wall to which said reglet is secured.
