.. . . . _ .
The present invention pertains primarily to building structures anil more par~icularly to roof edge construction.
Reference may be had to U.S. Pate7lt Nos. 4,071,9~7 and Re. 26,056, both owned by the sa~e assignee as the present in~rention, to show treatment for the raised edge or gravel stop, and fascia at the top edge of a ~ilding. The disclosures of these two abave-referenced patents are hereby incorporated in this application by reference.
It has generally been the practice in the erection of buildings having briclc or cement block walls and metal roof edging, to bolt a piece of wood or nailer to the edge of the building on top of the last row of bricks or cement blocks. ~etal edging is then fastened to -tllis wood nailer. As sin~ple as this procedure may appear in this over-sim-r)iif`ied surr~nary, the achlal step-by-step process is very involved and re~uires the coordination of several workers, as will be explained below.
In order to get a wood stud or nailer in its desired location, first a wall is made, for exa~nple, out of cement blocks. ~en the wall is c~npleted, steel J-~olts or threaded rods ZO are embedded into the voids or cavities in the top row of blocks using concrete or the lil~e. This contractor, typically a mason, usually fits a nut onto the exposed end of the threaded rod or bolt so that once the concrete has set, removillg the nut t~ill hlock any ~; rust off, since a clean -threaded end is needed. Once thc bolts are set and secured in place, a carpenter arrives at the job site with ;~ boards, gcnerally 2 x 4's, 2 x 8's, or whatever width is needed.
The carl~enter nrust carcf~ Ly drill ancl co~mter,ink these boards on ex~ctly the rigllt centers, r~move the nuts frorn the exposed, ~` thre~cled studs, dro~; the boards in p.lace over thc studs, and then, ,~ ~æ

-' . ~, ~ , ~.
:: : : : -" :,, ~, , ' ' using a washer and the nut removed earlier, tigh-ten the board down. This board, known as a nailer, is generally of pressure treated wood to retard rot. Finally, since it is difficult to set the studs exactly right a steel worker is sometimes required to burn off the exposed ends of the studs which protrude above the top of the nailer. Aftex all this has ~een completed, metal roof edging~ of a type shown in the two above-referenced patents, for example, is fit into place by a sheet metal worker, who attaches a metal mounting member of some type to the wood studs usin~ nails or the like.
It should thus be readily apparent that in addition to being a labor and time consuming eEfort~ the above-described procedure also requires the coordination of four trades, ; namely a mason, a carpenter, a steelworker, and finally a sheet metal worker. In this day of "fast track" construction, the fewer trades that depend upon each other, the faster the schedule can be made. A fast schedule and rapid completion of construction projects saves money because construction loans do not have to be carried as long at current high interest rates. In addition, the complexity of the overall project is reduced significantly.
Accordingly, it is a principa~ object of the present invention to provide an improved roof edge assembly which eliminates the need for the piece of wood or nailer which is normally bolted adjacent the edge of a roof for the purpose of fastening metal roofing edges.

' , According to the present invention -there i5 proYided an edge assembly for use in forming an edge on a roof building structure, the assembly including ~ tab strip member having integral tab means thereon and being securable adjacent the edge of the building, the tab means includ:ing a portion pro-truding in a direction generally away from the building. The -assembly further includes a cant member including a vertical portion having slot means therein whic~ mate ~it~ the tah means to secure the cant ~em~er to the tab strip mem~er, the slot means receiving the protruding portion of the tab means, the cant member hav;ng top and ~ottom edges and ha~in~ means for supporting the cant memher along the horizontal edge of the building. A fascia member has channel elements along the top and bottom edges which face in opposite directions .
generally towards each other, the top and bottom edge$ o~
the cant member being engageable with the channel elements to support the fascia member.
Since the wood nailer previous.ly used in the art is eliminated, the tab strip member, which has ta~ means thereon is secured directly to the ed~e of the roo~ using adhesive or other attaching means.
In a specific embodiment of the invention the tab strip member may comprise a semi-flexible perforated s.trip with tabs protruding from it so that a slottea cant member can be slid over the tabs, with the tabs then being bent or hammered down to lock the cant member in place. Alth.ough several different embodiments of the present invention are described herein, it should be appreciated that other variations or modifications are possible. ~n one tab strip ;'~

: ~ , ~: ' nailerless roof ed~e asscmbly lO of the present invention ~ ich is used to form a raised cdge or gravel stop on a roof deck 12. This embodiment is particularly suited to be used with a gra~rel stop of the type described u~ U.S. Patent No. 4,071,987, referred to S hereinabove. A tabstripmember 14 is secured to a top row of cernent blocks 16 on the edge of a roof usinS adhesive or the like.
~he adhesive is allowed to flow some~llat through perforations 18 in the tab st-ip membe~ 14 to improve adhesion. The extension of the adhesive through the perforations, while providing some additional holding force, primarily shortens the time required to set up the adhesi~7e. Insulation 20 is then placed on top of the roof deck 12 and overlaps the upper horizontal surface of the tab strip member l4. The tab strip mcrnber 14 has a series of tabs 22 -thereon thicharemated wit}) slots 24 in c~nt member or spring clip member 26. 11le cant member 26 is installed by position-ing its lower horizontal supportin~ portion 28 on top of the insulationpad 20 and tllell sliding its vertical portion 30 into engagement with the top row of cement blocks 16. Of course, the slots 24 in the cant member would have to be aligned with the mating tabs 22 in the tab strip member 14 before the vertical portion 30 of -the cant member could be brough-t up against the blocks 16. As sho~n in this fiL~ure, once the cant member has bel-n placed along the vertic~l surface adjacent the roof, the tabs 2Z are then bent or l-anDneled do~n to sealre the cant member 26 to the tab strip membcr 14.
Once thc cant manber or spring clip mcmber is secure, a roofillg sealing m~mbranc 32 of elastomeric material or tar paper is placcd c~l top of ~u~sulation 20. The roo-~ing mcmbranc 32 is brought up over the top edge 3~ of the cant m~nber 26 and is allowed to ex~nd c10wn to ne.lr the bot~orn edge 36 of tlle cant member.

A fascia member 35 ha~ing a top charnel element 40 and a bottom channel element 42 ~rhich face in opl-osite directions gcnerall~
to~ard each other, is then positioned on the top ed~e of the cant member. The cant member is then deflected dol~m~lardly and released so as to have its top and bottom-edges 34 and 36 respectively enter the facing channel elements 40 and ~12 rcspecti~ely of the fascia member 38. Although not shol~n in Fi~lre 1 gra~el is typically placed on top of the roofing sealing memhranc 32 ;

Referring now to Figares 2 and 3 two different - 10 arrangements of slots are shown in cant melnbers 26 and 44 respectivel~. In both arrangements the slots aMear at various le~els to accommodate different thicknesses of insulation ~hich ` would be installed under the slotted cant member. Figure 2 shol-s slots 24 in a staggered arrculgement whereas Figure 3 sho~s slots 46 in an in-line arrangement. Frcm a mcmufactur;ng point of view it is believed that staggered slots may be preferred, although both arr~mgements provide slots at at least fo~lr ` ~ i different levels. For cus-tan insulation thicknesses, only one ~ row of slots might be needed and that roll could be prefabricated -~ 20 at the factory to meet speci-fic job conditions.
Figure 4a illustrates the cc~lt member 26 and the tab strip member 14 of Figure 1 before the protruding tab 22 has been bent do~-~. Figure 4b illustrates the same cant mc~mber and tab strip member after the protmdiug tab 22 has been bent do~n to sec-lre the cant member in place.
- Fig~re 5a shoi~ls a tab strip melnber 45 ~hich has an oE~set horizontal element 50 at its back e~:l which is adapted to engage a c.mt m~qnbcr or spring clip member 5Z. lhe forward side of this c-nt manber 52 is slotted in a n)anner similar to the , .,,.~.J

cant membcr of Figure l so as to mate with a tab 54 in the tab strip member, and has a ~enerall~ planar ~ertical portion 56 which cxtends Erom a bottom edge 58 to a top edge 60, before joinin~ an ang~llar portlon 62 ~hich slopes rean ardly to join a back leg 64 which engages the offset ele~nent 50 to s~lpport the cant ]nember along the hori~ontal edge ot the roof. Figurc 5b shows a san~.what similar construction in whicl an offset horizDntal portion 66 on a tab strip 68 may be bent dol~n, as indicated by the arrow, after cant m~mber 70 is in place.
Figure 6 sho~s another preferred embodiment of the nailerless roof edge assembly 72 of the present invention. This embodiment is particularly sl~itec3 to be used with a cc~mbination water darr and gravel stop OlC the type clescribecl in U.S. Patent No. Ro. 26,056, referred to hereinabove. In this embodinlent, a lS tab strip m~nber 74 is securcd to a top row of cement blocks 76 on the edge of a roof using adhesi~e or the like, which is allowed to f1OW somewllat through p~rforations 78 in the tab strip member 74 to improve adhesion. Although not shol.n in this figure, insulation, such as that illustrated in Figure 1 may be placed on top of the roof deck so as to overlap the upper horizontal surtace of the t~b strip m~nber 74 at its back end. The tab strip member 74 has a series of tabs 80 on its fon~ard end which -are mated ~ith slots 82 in cant m~mber 84. Cant member 84, which - is generally in the shape of an inverted -V, has a vertical por~ion 86 having slots 82 near its botta~l edge 106 wh;ch mate with tabs 80, cmd an angular portion 88, which has a horizontal supI)ort flange 90 on its rearwardmost end. Plan~ie 90 has slots 92 therein w~ich mate with tabs 94 formed on the rear~ard end of tab strip member 74. ~le flange 90 supl~orts the cant m~nber 84 along the horizont~l cdge of the roof.

;5 Once the cant member or spring clip member 84 is secured, a roofing sealing mernbrane 96 is placed on top of the roof and brought up near the top edge 9~ of ~he cant m~nber. A fascia member 100, having a top channel elemellt 102 and a bottom channel element 104 which face in opposite directions generally towaTd each other, is then positioned on the bottoln edge 106 of the cant me7nber, and movcd so that the top channel element 102 engages the top edge 98 of the cant me,-nber ~4. Al-though not absolutely necessary to the practice of the present invention, a rocker flashing 108 may be used to further secure the fascia member 100 -~ to the cant me)nber. As shown in Figure 6, an upper edge 110 of the Elashing 108 projects into the channel 102, with a lower portion 112 of the flashing being fastened to the angular portion :~
88 of the cant m~snber 84 to secure the roof e~dge assMnbly. Gravel is then typically placed on top of the roofing sealing membrane 96. I~is parti~ular configuration is explained in greater detail in U.S. Patent NQ. Re. 26,056, ~s referred -to above.
Referring noi to l~igures 7PI and 7b, two different types of tab strip members are shown. The tab strip member 74 of Figure 7a comprises a generally plansr horizontal portion 114 having perforations 73 therein, a first set of horizontally extending tabs 80 on its forw~rd edge, and a secor~l set of vertically extend-ing tabs 9~1 on its rearward edge. The tab stri~ m~mber 116 of Figure 7b is of a configuratiorl generally similar to that of the tab strip member of Figure 7a, howc~ver, rather than being perforated, the generally plan.lr horizonta] portion 118 is made of e.^cpsnded metAl. Bo~h a irst and second set of tabs 120 and 122 respectively, arc used in this conEiguration. An expanded metal version is particularly attracti~e due to the fact that since the ~ne-tal is . ' .

laterall)~ stretched, it goes further. Thus the final piece costs less.
Fi~lre 7c more clearly shol~s the cant member 84 of Figure 6. As described in connection with Figure 6, this cant member comprises a vertical portion ~6 joining a bottom edge ~06 to a top ed~e 98. ~n .mgular portion 88 e.~tends in a down~ d angle frcsn the top edge 9S do~n to the horlzontal support flange 90. Slots 82 are present in the vertical portion, while slots 92 are present in the horizontal flange 90. As with the cant member described in connection with Figure 1, a variety of slot configurations ma)~ be fabricated into the cant member to accc~nodate various thicknesses of insulation or other strucnlral variations. As before, the slots may simply be prefabricated in certain pre-specified locatiolls to meet speciFic job conditions.
Figure 8a illustrates the cant m~nbcr 84 and the tab strip member 74 of Fic~lre o before the protl~lding tabs 80 and 94 have been bcnt do~m. Figure 8b illustrates the same cant member f~nd tab strip member after the protruding tabs have been bent dol n to hold -the cant member in place.
It should of couIse be c~.preciated that the specific configurations of both the tab strip m~nber and the cant member used with the present invention may be varied as necessary to suit particular needs. T}le follo~incg arc e~amples of various tab strip member configurations which are adaptable for use with eithcr of the prcferred embc~3inents described above. Of cGurse, an additiollal realward tab woul(l l ave to be added to accononodate a confi~uration of thc type sho~,m in ~:ic,~ure 6.
Fi~ures 9a and 9b illustrate tab stril~ members 124 an~l 12G res~ectively, ~/hich are of unit confi~lration. Such unit i ~ _g_ , :, ' ` .

tab strips, W]liC}l include a single tab thereon, could be individually positioned as necessary along a roof edgel thus eliminating the need for a single long tab stri~ having several tabs thereon. n~ese tab strip members are sho~n as havin~
perforations therein ~hich aid in attachmentto the edge of a roof.
Figures lOa, lOb, an~ lOc all sho~ flat tab strip nanbers 128, 130, and 1~2, respectively~ However, different types of perforations are sho~n in each figure. Figure lOa shows : 10 perforations 134 which are continuous over the horizontal portion of the stri~, whereas the perforations 136 sho~n in F;~lre lOb are localized on the horizontal portion of the strip adjace.nt the tabs 138. Perforations of the type sho~n in Fig~ires lOa and lOb may be formed by punching out small holes in the sheet metal. ~lo~ever, as an alternative to punched-out perforations, Figure lOc sho~s a tab strip member 132 where the sheet metal has been burst or pierced to give the desired holes 14Q in the horizontal portion of the strip.
F:igure 11 illustrates a tab strip member 142 of the type shown in Fi~Fe 1 w}lerein the strip is formed so as to contain a horizontal portion 1~4, tabs 146 coplanar and integral witll the horlzontal portion, and a series of downwardly-extending vertical flaps 148 which are fonned out o.f the same piece of strip stock as the horizcntal portion. ~le vertical flaps 148 are generally perpendicular to the horizontal portion 144. ~lis particular con~ ration, as well as many of the others descri.bed herein, may ~lso be used upside-do~n so that the vertic~l flaps extendi uph~ardly.
Figure 12 illustrates a tab strip m~lber 150 wherein generally planar vertical f].aps 152 extend both above and below the hor;zontal llortion 156. Tabs 154 are coplanar and ,, ~, ,, :

integral with the horizontal portion 156. ~le top edge of the vertical flaps joins an an~llar ramp 158 which is formed adjacent the horizontal portion. The ramp has its base on the horizontal portion and is inclined up to a point of contact ~ith the top ed~e of the vertical flaps. Figure 13 sho~s a tab strip me~nber 160 some.~at similar to Figure 12, ho~ever the tabs 162 are formed out of a vertical pcrtion lfi4 rather than from a horizontal portion 166.
e tabs 162 are still generall~ coplanar with the horizontal portion. ~le vertical portion 164 has a ramp 168 on its rea~ard side and extends both above and below the horizontal portion 166.
Figure 14 illustrates a compound or "two-piece" tab strip member 170 wherein the tabs 172 comprise wires or bolts or the like which are secured to the horizontal strip 174 by such methods as soldering, gluin~s~, br~2ingJ wclding, etc. Figure 15 illustrates another compound tab strip mcmber 176 wherein the tabs 178 comprise a metal strip folded over so that it contacts ~; both the upper and lower surfaces of the horizontal portion 180 ~;
of the strip. ~he metal strip forming the tabs 178 may like~.~ise be soldered~ glued7 brazed, ~elded, etc. to thc horizontal portion 180 of the strip.
~igure 16 illustrates a compound, formed tab strip mernber 182 ~herein wire or bolt tabs 184 are attached to a strip having a cont;nuous horizontal portion 186 and a downwardly extending vertical portion 188 which is generally perpelldicular to the horizontal portion. This conEiguratioll is also particularly suit~l for use upside-down. Figure 17 illustrates another compound, formcd tab strip mcmber 190 which is sontewhat similar to thc confi~uration of Fi~ure 13 in tc~ns of its vcrtical portion 192, ramp 19~, and horizontal portion 196.

p~rtion 204 such that the tabs 202 vertical portion 206> and horizontal portio~ 204 form a step-li~e c~nfi~urati~n. It is also noteYorthy that this partia~ar conri~Iration shows perforations on both the horizontal and Yertical portions, although both sets of perforations are not necessary to the practice of the ~resent invention. It should of course be appreciated that such a distribution of perforations is equally adaptable to the other tab strip config~Irations disclosed herein. Figure 19 illustrates a tab str;p member 20S having a vertical portion 210, ramp 212, and hor;zoJ~tal portion 214 similar to the strip shown in Figure 17.

similar tab strip member 240 having tabs p~mched out f}an underneath, ~herein a first set of tabs 242 is coplanar with a horizontal portion 244 and a second sct of tabs 246 ;s coplanar with a vertical portion 24~ Ihis type of configuration would - 5 aid in aligning the strip on the corner of a block wall, since the horizonta:L portion 244 and tabs 246 would help position the strip Figure 24 illustrates a tab strip member 250 ~iherein tabs 252 are generally hook-shaped. Such a config~ration would allol the slots of a mating cant member or spring clip member to be placed o~er the tabs and then shifted laterally to help insure that thc cant m~nber is attached once the tabs are bent over.
Figure 25 illustrates a sc~ne~rhat sirnilar tab strip m~nber 25~ in - which the tabs 2S6 are both hooX-shaped and bent over prior to :~ lS installation or a mating c--,nt member. Illus a cant mernber would be secured solely by a lateral shift rather than by bending over . any tabs, as is the casc in most of the other embodiments sho~.n herein. ~igure 26 illustrates a ~ab strip member 258 in wllicll bent over,hook-shaped tabs 260 are offset from a vertical portion 262 to provide a gap and give more clearance -for latcral movement of a mating cant member.
Figure 27 illustrates a tab striI~ member 264 ~d~erein upwardly and dowm~Jardly directed vertical flaps 266 alternate .~ direction between tabs 268. In a further modified for~n of -this cot~figuration, Figure 28a illustrates a tab strip men~ber 270 similar to the strip of Figure 27 except with no protruding tabs on its .face. As seen in Figure 28b, a c.mt member 272 would be secured ~o thc tab str.ip m~nber 270 usinr, s~lch manual tabbing means 274 as screws, pop-rivets, or the like. lloles or slot means would be providcd in the matinr C~Ult m~ber to receive the .

Tl~.e tab strip member9 cant member, and fascia member used ~ith the present invention may be mc~e of such material as galvanized steel sheet. Besides galvani~eo metal, aluminum, stainless steel, plastic, or the like may also be used. The various components may also be painted or coated as necessary for both protective and decorative purposes. Needless to say, the tab stril- member should be relatively fle~cible or ductile so that the tabs thereon can be bent over without too much effort. Also, the tab strip member should be flexible encugh to be able to deform or compensate for ~ any irregularities in the ce~.ent bloclcs or concrete.
`~ Among the advantages of the present invention, in . ~ addition to those described above, is that since a wood nailer is no longer necessary along the roof cdge, the cost of material and ;~ 15 labor of`installing ~oc~ nailers is eliminated, and ~Irthernlore , there is no concern for rotting wood. Since the roof edge assembly of the present invcnticn coml~rises parts made from sheet metal or the like, the roof edge assembly allows any insulation layer to breathe at the roof edge where it counts mDSt. The usual problem of trapped water is likewise virtually eliminated. The nailcrless roof edge assembIy of the present invention also provides -for simple, fast, and eccncmical installation, but yet has been shown to provide respectable holding power of about 200 pcunds per foot in certain constructions. Since the installation of the nailerless roof edae asscmbly of the present invention wculd probably be the responsibility of a single contractor,namely a sheet metal worker or the like, no carpentcrs, masons, or steel workers would be needed. Job scheduling is thLls simplified, as is the time necessary l~or ccmpletion of various jobs. The relative s.unplicity of the 3D ass~nbly and installation proceclure likewise ma~es it ideal for : ~ . .... . . . .. , :

A~though most of the description of the present invention givcn above has been directed to a roof edge assembly, it should be apprcciated that the pru~ciples of the invention are S e~lally applicable to other cdges on building structures, such as corners, windo~s, doorways, or the li~e.
l\hile it will be apparent that the ~referred embodiments of the invention disclosed are well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation, and change without departing from the proper scopc or fair mean;ng of the subjoined claims.
