BACKGR~VND AND SU~A~Y OF T9E INVENTI~N
The invention relates generally to building structures and more particularly to roof edge constructions ior such building structures, wherein the rooi edge assembly serYeS to sealingly anchor and clamp a sheet-llke roofing material or membrane along the edge of the building structure.
Variou~ rai~ed rDof ~dge a~semblies, gravel s$op assemblies, water dams9 and the like, have been pr~vided ~or puxposes of anchoring ~heet-like rDofing membranes, retaining gravel ballast~ or other roo~ing materials, controlling ~ater drainage, and Por ~upporting fa~cia members at the edge of the rooi oi a building 6tructure. Examples oY such previously-pro~ided as~emblies are disclosed in United States Patent Nos.

~ The roo~ edge assemblies di~closed in the above-re~erenced ,.
patents repreeent great strides over previ~uæ ~oo~ ~dge constructions in . .
terms of stabillty,~ simpliclty, oost-e~iectiveness, ease of installation, and e~ectiveness ~n archoring roo~ing membranes. It has been iound, : however, in many iDstances that it i6 desirabl~ to even .~urther increase ~ the anchoring engagement, and thu~ t~e ~ealing, o~ a roo~ing material at , the edge o~ a buildlng atructure without penetrating through the roo~ing ', .

m~terial, at least on the rooi side of the ~tructure, and to iurther increase the resistance o~ the rooi edge asfiembly to wind or other uplift loads. It has also been found that tbe use o~ preiormed roof-covering mffmbers, Yrequently referred to a8 "roofing pa~ers", or "roof paving blocks", has ~ecome desirable in some applications, and thus the use of such roDfing pavers has dramatically increased.
In addition, earlier methods of $inishing the roof edges of building structures having ~heet-like rDDiing membranes have required the use o~ Gants, gravel~tops, or other 6uch devices to hold back ballast and rDo~ debri~. In such in~tallations, the roofing membrane i8 ~r~quently installed so as to extend o~er the edge device and i~ either clamped or bonded to it. ~oder~ roofing membrane materials, however, are ~requently adhered directly to the roo~ deck, and thus do not require gravel or other lo~se ballast to pr~tect and h~old the m~mbrane in place.
There~ore, ex~ept uhere the ~ove~menti~ned roofing pavers are found to b~ de~irable or ~dvantageous, lt is ~re~uently possible to ~inish the roo~ edge without using a ~ravel ~top or cant, but rather to place a relatively low-pro~ile clamping member or c}amping rooi edge assembly over the membrane to anchor and secure the membr~ne at the ~oDf edge.
Thus, the present inventi~n ~eeks to provide uch n roo~ edge assembly that i~ eimple and relatively inexpen~ive to m~nufacture and install, that e~fectively seæl~ and anchor~ the rov~ing membrane along the roo~
edgej ~and that is capable o~ ~ccommodating thermal expansi~n and extraction o~ the roof edge a~e~hly along the longitudinal edge oi the building ~tructure rDoi.

the assembly is in~talled thereon, with the building ~tructure having a generally horizontal rooi suriace and a gene~lly vertical iace suriace, with a ~heet-like rooiing material or membrane extending along the horizontal rDof surf.ace and overl~pping a portion oi? the vertical l?ace &urface. The rDof edge assembly according ~o the present invention includes a relati~ely thin, but relatively rigid, clamping member, a portion oi which has a generally L,shaped lateral cro~s-sectional ~hape defined by a generally hor~zontal leæ portion and a generally vertical leg portion. The horizontal leg portion i~ adapted -to engage the hori~ontal roo.l? sur~ace, and the vertical leg portion i8 ~dap~ed to engage the vertical iace portion o~ the building s~ructure, with the ~heet-like rooiing material clamped between the building structure and the clamping member. The horizontal leg portion includes an up~ r edge p~rtion configured su as to be ~paced generally a~ay f~om the horizontal ro~i ~urIace, and similarly the ~ertical leg portion include~ a l~wer edge portion configured so as to ~e ~paced generally awaiy lrom the vertlcal ~ace of the r~of.
The cla7r~ping member ~urther includes a discont~nuity protruding generally away fnom the building 6tructure adap~ed ~or engaging a portion o~ a re~ ent fascia member and resiliently biaeing the ~ascia mæmber in a dlrection generally outwardly when the ~scia member is ~ecured to the clamping m~mber. Such outward re~ilient bia~ing tend6 to urge hooked ~aecia portions into a relatively tight engag~ment with the corresp~ndi~g, respective upper and lower edge portions o~ the alamping member.

V-shaped discontinuity adapted ~or engaging a portion o~ the resilient ~ascia member. The V-shaped discontinui~y can be located generally adjacent the iDtersection of the vertical and horizontal leg portion~ of the clamping member, thus also limiting the i.nward position o~ the fascia member and oorrespondingly maintaining the fascia member in a properly allgned, rattle-~ree di~position. In ~ embodiment~ c~ the present invention, wherein the above-mentioned roofi.ng pavers are deemed to be desirable or advantageous, the clamping mem~er als3 includes a generally upwardly-extending p~rtioD di~posed between the horizontal leg portion and the upper edge portion, thus ionming a higher-proiile, ralsed roof ~dge con~igNration adapted to engage ~oof paving blocks alo~g the edge of the roo~ ~hen in6talled on the building structure. In any oi the em ~ iments disclosed and claimed herein, the preierred cl~mpiDg m~mber i8 adapted bo be di6posed in an overlappi~g relationship between adjacent clamping member pDrtions at the joints therebetween.
In additian, it i6 preferred tbat at least the above-mentioned clamping member be cNmposed of galvznized steel, ~hich has a lower ~3e~ficlent o~ e~pa~sion than ~ome other materials, ~uch as aluminumJ for example. Such lo~er coef~icient of expansion rasults in le68 6~ress on, and conse~uent posæible damage to, the rooiing material and the caulking or ga~ket material~ ny i~ used, between tbe clamping member ~nd the roofing material.
Additional object~, adv~ltages, and ~eatures o~ the present invention will become apparent ~om khe ~ollowing de~crip~lon and appended claims, taken in oon~unction with the 2c~0mpany1ng drawings.

In Figures 1 and 2, a preierred :r~of edge a~embly 10 ~or forning a r~ edge on a horizontal roo~ surface 12 oi a building ~t.ructure 14 generally includes a clamping member 16 and a fascia member 18 assembled ~or sealingly anchoring a ~heet-like r~ofing material 20 extending along the horizontal roof eur~acl 12 and overlapping the verti~al ~ace 22 of tbe building structure 14. With the roo~ edge ~ssembly 10 of the preseDt invention, no fa6teners, and thereiore no penetrationæ, are neoeæsary along the h~iæontal r~oi ~urface la, thus eliminating the possibility of leake in the ~heet-llke roo~ing material 20 resulting ~rom ~Nch penetrations. Rather, the clamping member 16 i6 merely attached to the vertical face 22 o~ the building structure 14 by way of faæteners 24, which can be threa~ed fastene~æ, nail~, ~r other ~uitable fasteners known to tho~e ~killed in tbe art.
The clamping mQ~ber 16 has~ an in~erted9 geDe~ally Lr~haped croes-sectional oon~iguration~ which i6 de~ined by a generally hori~ontal leg portl~D 28 and a gene~ally vertical leg porti~n 3D.

The fascia mæmber 18 al~D include~ a generally horizontally-extendi4g upper portion 44, having a hooked upper edge portion 46 thereon, with a ~imilar hooked lower edge portion 48 being di6posed at tbe lower end oi the generally vertical lower portion 42.
Thus, ~len the clamping member 16 i~ ~ixedly 6ecured to the building structure 14, by way of the ~asteners 24 6ecuring the vertical leg portion 30 to the vertiral face æ, the ~aecia me~ber 18, which is pr~erably ~ormed oi a relatively resilient material, can be ins*alled on ~he clamping member 16 by hooking the hDoked lower edge 48 oi the ~a~cia member lB onto the lo~er edge portion 36 of the clamping member 16, and then ~napping the hooked upper edge pDrtion 46 o~ the fascia member 18 ~er the upper edge portion 26 ~f the clamping member 16.

present invention eealingly clamps and anchors the roo~ing material 20 along the rooi edge of the building structure 14.
As is Epeci~ically shoun~ in Figure 2, the cla~ping me~ber 16, although relatively rigid, is also relatively thin 6uch that adjacent cl~mping members 16 overlap one ~nother end--to-end at the joint between their ends 40, thus ~urther eliminatlng or ~bstantially minimizing the possibility o~ leak6. In this regard, although not speci~ically shown in Figures 1 and 2, a generally L,~haped splicer plate c~n optionally be positioned between the clamping member 16 and the ~ascia member 18 at ~oin~s between longitudinally-adjacent ~ascia member components.
Furthermore, ~ deemed desirable or ne~es6ary in a given application, an optional seallng me~ber vr sealant bead 50 can be positioned along the hDrizontal rooï sNrface 12, ad~acent the roDi edge, and ~ealing compreseed by the clamping member lB w~en the olamping rnember 16 is 6ecured to the v~rt1cal iace 22. In ~st instances, ho~ver, it is beli~ved that the optioDal sealant bead 50 need nct be provided ~ince ~he horizontal leg port~on 2B clampingly and sealingly engages the roofing material 20 directly u~len the ~rtical leg portion 30 of the clan~>ing ., member 16 is 6ecured to the vertical face æ of the ~uilding ~tructure 13.

As illu~trated in Figures 3 and 4, the roo:~ edge a~sembly c~nents oi Fig~res 1 and 2 can be modi:eied slightly in order to forrn ~n outside corner configur~tion, represented in Figures 3 and 4 by the :outside corner roof edge ass~nbly 110~ Various features and caTlponents o~ the out~ide oDrn~r ~D~ edge assembly ltO are identical or similar, in either configurati~n or ~unction, to c~rrespoDding ~eatures and ooLp~nents o~ the rooi e~ge as6embly 10 ~hown in Figure~ 1 and 2. Thus, , : , .

6urh corresponding ieatures or co~ponent~ are indicated by reierence numerals in Figure~ 3 and 4 that are o~e~h~nd:red higher than thoæe o~ the oorresponding ~eatures ~nd oomponents ~hown i~n Figure~ 1 and 2.
The outside corner roof edge a~sembly 110 is ~abricated by cutting ~ut a generally V-shaped cut-out portion 156 in the upper portion 144 of the fascia member 118. Similarly, a generally Y-~haped cut-out portion 158 i~ ~ormed in the hooked lo~er edgle portion 148 o~ the ~ascia 118~ ~ith the cut-out portion 156 and the cut-out portion 15B being interconnected by a bend line 160 rep~esented ~y a phantom line in Figure 3. In addition, a portion of the hook~d upper edge portion ~46 o~ the ~a~cia member 18 is CNt away ad~acent ~he CUt-DUt porti~n 156, al~ng a length generally equal to the width oi th~ u~per portion 144. Th~6 io~
a tab 157 which, as i6 illustrated in Fig~re 4, i6 positioned under the adJacent upper portion 144 when *he ~ascia member 118 i~ bent into an *
angulated configuration along the bend 1inP 1~0~ Once iormed into the outside corner con~iguration ~hown in Figure 4, the ~scia m~mber can be ~napped onto adjacent cl~mping member oomponents 1~, which are previou~ly .

installed OD the building ~tructure in an out~ide-ccrner angulated configuration.
In a manner generally similar to that lllu~trated in Figures 3 and 4, an inside c~rner rooi edge as ~mbly 210 can be ~abrica~ed irom the ~omponents o~ Fi~ures 1 and 3, and ~uch an arrang~ment i8 illustrated in Figures 5 and 6. The ~eatures and components o~ the inside corner roof edge aæ6embly 210 in Figure6 5 and 6 are identioal or similar in conilguration or iunction to corre~p~nding elffments o~ khe rvoi edge a~emblies ~hown in Figures 1 through 4, and thus ~uch corre~ponding , ,' .

To ~orm such an in6ide corner rc~i edge as~embly 210, the ~ascia member 218 is cut ~uch that a miteredl edge 264 i6 ~ormed on the upper p~rtion 244. Another ~ascia oomponent 218 is cut generally along the inter~ection of the lower portion 24Z andl the upper portion 244, with the cut portion o~ the lower portion 242 being bent outwardly, resulting in a generally vertical tab portion 257 and a generally horizontal tab portion 259, ~hich are illustrated in the exploded illustration o~ Figure 5~ ~hen the adjacen~ ~a~cia ccmponents are ~oined together, the vertical tab portion 257 underlaps the verkical lower portion 242 oi the adjacent ia~cia component, and the generally horizontal tab portion 259 underlaps the horizontal upper portion 244 in a similar manner. Once ~oined t~gether ax ~hown in Figure 6, ~he ~oint between the adjacent ins~de aorner component~ san optionally be welded or otherwiæe ~ealingly ;
oonnected along the joint line 260 and the mitered edge 2~. The ~sembled ins~de oDrner iæ then snapped onto adjac~nt cl&~ping mem~er 16, :Nhich have been secured bo ths in~ide corner vertical ~aces o~ the b~ilding ~*~ucture to ~orm the inside co~ner cDnfigNration ~hown in ~igure 6.
: Figure 7 illu6trates an alternate ~onstruction o~ a roof edge ~s~embly 310, which i~ 6ub6tantially similar to that of the roo~ edge assembly 10 shown in Fi~ures 1 and 2, and thus corresponding or ~imilar element~ a~e indicatecl by sim~lal reierence numerals, b~t with three-hundred pre~ix Q in Figure 7. The major dif~erence between the roof edge a~6embly 310 oi Flgure 7 and the rDoi edge assembly 10 of Fi ~ res 1 and 2 is the fabrication oi the iascia member wlth vertical 1.

lower p~rtions 42 that are ~ubstantially equal ~n width to the horizontal upper portions 44, thus resulting in a eym~etrical con~iguration such that the fa~cia member 318 can be &napped onto the clæmping ~ember 316 with the upper portion 344 and the lower portion 342 being interchangeable. SuGh a oon~iguration proYides advantages in terms o~
flexib~lity oi installation in certain applications.
As with the ~oo~ edge assembly 10 shown in Figures 1 and 2, the ~ealant bead 50 ~hown in Figure 1 c~n optionally be incl~ded in rco~ edge assembly 310 o~ Figure 7, or i~ ~ny o~ the em~cdiments o~ the invention, and inside ~r ~utside cvrner con~igurations can be ~abricated in the embodiment of Figure 7, or any o~ the ~ther embodiment~ ~hown herein, in a manner 8imilar to that sho~n ~n Fi~ures 3 thrDugh ~.
In Figure 7A, a variation on the clamping member 316 is indicatedlby re~erence numeral 316a, and ,~imi~arly other ~orre~ponding ~ ;
elements or oomponentæ are denoted by reierence nun~rals cbrre~ponding to th~se o~ Figure 7, but having the su~ix 'la". The clamping mem~er 316a di~iers ~rom the clamping me~ber 316 in Fi~re 7 prlmarily in that the discontinuity 334a protrudes ge~erally upwardly rather than generally hDrizontally to engage the upper p~rtion 349a, rather than the lower portion 342a, o~ the ~Q~cia ~ ber 318a.
~ ~ In FigNre 8, the roo~ edge afisembly 410 is ~imiIar in many respects to tho~e di~cu~6ed above and illu~trated in the preceding ~igures and thus has ~im:llar or corresp~nding elements indicated by ~imilar reference numeralsl but having ~our-hundred pre~ixeæ. The roo~
edge as~embly 410 6hown in Figure 8 di~fer6 ~rom the pr~viou~ly-di6cussed rooi ed~e a6sembli~s primarily in the provision oi a generally upwardly-exkending portion 466 o~ the clamping mæmber disposed ~etweeh : : .

the upper edge portion ~26 and the hori~ontal leg portion 428, with a corresponding height increase being provided in the vertical lower portion 442 ol' the i'ascia member 418. S~uch additional height allows the roof edge assembly 410 to be adapted ~or prcviding a Etop ior roo~ing pavers 468, if sNch roofing pavers are deer~!d desirable or advantageous in a particular installa~ion. The cbnfiguration vi' the roof edge as6embly 410 thus i8 configured ~uch that ~he upwardly-extending portion 466 abuts the edge o~ the roofing p~vers 46~9 and acting in conjunction with the upper edge portion 426, serve~ to retain tbe rooiing pavers 468 in place along the edge o~ the roo~ structure.
Figure 8A illustrates a variation on the clamping member 416 of Figure 8, with the cl~m~ing m~mber 416a o~ Figure 8A having a protrusion ~r discontinuity 43~a extending generally outwardly to be re~iliently deflectable generally vertically and to thus engage the upper portion 444a9 rather than the lower porti~n 442a, o~ the fascia member 418a.
Figures 9 and 10 illu~trate tw~ f~rther alternate embodiments of the pre~ent invention, which are gènerally ~imilar to those previously di~cuæsed, ~uch as the roo~ edge as6embly 10 illustrated in Figures 1 and 2, 1n particular. As with ~ther alternate 2mbodi~ents describ~d herein, variou~ coOEponents and features o~ ~he roof edge a~seIblies 510 and 610 depicted ln Figures 9 and 10, re~pectively, are similar in c~n~iguratio~
