The roof edge structure includes a cant having an outer vertical portion secured to the outer edge of the roof and having an inner inclined portion secured to the roof, with the rooting plies laid thereover. The upper end of the cant outer vertical portion is integrally joined to the upper end of the inner inclined portion. The roof edge structure further includes a fascia member having the lower end releasably engaged with the lower end of the cant outer vertical portion, and having the upper edge thereof folded inwardly, and downwardly and outwardly, to form a hook with an upwardly facing support lip. The roof edge structure further includes a sealer strip having a downwardly facing hook formed along the upper edge thereof and extended into the hook formed along the upper edge of the fascia member, with the edge of the sealer strip hook engaging said support lip. The sealer strip has its upper end in pivotal engagement with the outer end of the cant vertical portion and with the sealer strip body portion pivoted downward into sealing engagement with the roofing covering so as to move the fascia member downwardly and the upper end of the fascia member inwardly, and the lower end of the fascia member outwardly into sealing engagement with the lower end of the cant vertical portion. The roof edge structure further includes means for securing the sealer strip to said cant inner inclined portion to compress the rooting covering against the cant inner inclined portion to form a weather seal.

SUMMARY OF THE INVENTION This invention relates generally to roof edge structures and more particularly to a combination water dam, sealer strip and fascia structure which functions as an edge structure for a flat roof deck.

Roof edge structures are well known in the art. An example of a prior art roof edge structure is one which comprises a combination water dam, sealer strip and fascia structure, and wherein the sealer strip is rockably mounted on the rooting material to provide an upward thrust against the upper end of the fascia member for securing the fascia member in place. A disadvantage of the lastmentioned prior art roof edge structure, and similar devices, is that the sealer member is pivotally mounted on the roofing material on the upper end of the water dam or cant, and the thickness of the roong material on a single roof varies so that it is not possible to provide a positive and accurate pivot point for the sealer strip. A further disadvantage of the aforementioned prior art roof edge structures is that they provide only a single line of sealing between the roong material and the Water darn or cant and the roong material must be trimmed flush with the upper pivot end of the cant. A still further disadvantage of the aforementioned prior art roof edge structure is that due to the pivot arrangement of the sealer strip it is diflicult at times to mount the fascia member in position because of the overly thick roong material Ff"ce on which the sealer strip is pivoted to provide the required upward thrust for securing the fascia member in position. Accordingly, in view of the foregoing, it is an important object of the present invention to provide an improved combination water darn, sealer strip and fascia structure fora roof edge structure which overcomes the aforementioned disadvantages of the prior art roof edge structures. i

It is another object of the present invention to provide a combination water dam, sealer strip and fascia structure which is constructed and arranged so that the sealer strip pivots about the upper end of the darn, in direct contact therewith, and the sealer strip also engages against the rear face of the fascia member andy moves the fascia member into a secured position with a downwardly and inwardly directed force against the upper end of the fascia member.

It'is still another object of the present invention to provide a combination water dam, sealer strip and fascia structure which is mounted around the edge of a roof edge, with the roong material plies extended over the water dam or the cant, but wherein the rooting material plies do not extend to the upper end of the water dam or cant.

It is a further object of the present invention to provide a combination water dam, sealer strip and fascia structure for a roof edge and wherein the sealer strip moves the fascia member into a xed position with a force exerted against the upper end of the fascia member that acts in a downward and inward direction, so as to move the fascia member downwardly and the upper end of the fascia member inwardly and the lower end of the fascia member outwardly.

It is still a further object of the present invention to provide a combination water dam, sealer strip and fascia structure for a roof edge wherein the sealer strip is adapted to form a plurality of compression seals on the roofing material.

It is still another object of the present invention to provide an edge structure for a flat roof having a built-up roofing covering including a plurality of roofing plies, and such structure comprises a cant having an outer vertical portion extending above the roof and secured to the outer edge of the roof, and having an inner portion inclined inwardly and downwardly to the roof and secured to the roof, with said roofing plies laid over said inner inclined portion; the upper end of the cant outer vertical portion being integrally joined to the upper end of the inner inclined portion; a fascia member having the lower end releasably engaged with the lower end of the cant outer vertical portion, and having the upper edge thereof folded inwardly, and downwardly and outwardly, to form a hook with an upwardly facing support lip; a sealer strip having a downwardly facing hook formed along the upper edge thereof and extended into the hook formed along the upper edge of the fascia member, and with the edge of the sealer strip hook engaging the upwardly facing support lip of the fascia member hook; said sealer strip having its upper end in`=pivotal engagement with the upper end of the cant vertical portion and the body portion thereof pivoted downward into sealing engagement with said rooting covering so as to move the fascia member downwardly and the upper end of the fascia member inwardly, and the lower end of the fascia member outwardly into a retaining engagement with the lower end of the cant vertical portion; and means for securing the sealer strip to said cant inner inclined portion and to compress the rooting covering against the cant inner inclined portion to form a weather seal.

Other objects, features and advantages of this invention will be apparent from the following detailed description, appended claims, and the accompanying drawing.

BRIEF DESCRIPTION OF THE FIGURES IN THE DRAWINGS FIG. 1 is a fragmentary, vertical section view, in perspective of an illustrative embodiment of the present invention; and

FIG. 2 is a slightly reduced, elevational section View of the embodiment of FIG. 1, taken along the line 2--2 thereof, and looking in the direction of the arrows.

PARTICULAR DESCRIPTION OF THE INVENTION Referring now to the drawing, and in particular to FIG. 2, the numeral designates a vertical wall member which is connected to the lower side of a conventional base roof deck 2 x 4 portion 11. The numeral 12 designates the roof insulation portion of the roof deck. The combination water dam, sealer strip and fascia edge structure of the present invention functions as an edge structure for a flat roof deck, as illustrated in FIGS. 1 and 2.

As shown in FIGS. 1 and 2, the combination water darn, sealer strip and fascia structure of the present invention broadly includes a metal water dam or cant generally indicated by the numeral 13, a metal fascia generally indicated by the numeral 24, and a metal sealer strip generally indicated by the numeral 31.

The water dam or cant 13 may be made to any desired length and from any suitable material, as for example, galvanized sheet metal. The water cant 13 comprises an outer vertical portion or leg 14 which is secured to the outer side of the roofing deck 2 x 4, 11, by any suitable means, as by a plurality of l" long galvanized roofing nails 15. The nailsv 15 may be employed at any desired center spacings, as for example at 24 center spacings. The water cant 13 further includes the integral, downwardly and outwardly inclined, or sloping, flange 1,6 on

the lower end of the vertical leg 14. The flange 16 functions as a drip edge.

It will be seen that the water cant vertical leg 14 extends above the rooiing deck 2 X 4, 11, for a predetermined distance, as for example, 3" or 4", as desired. The water cant vertical portion 14 terminates at its upper end in an integral, downwardly facing U-shaped channel 17. The water cant 13 further includes an inwardly and downwardly inclined inner portion which comprises a first inclined leg portion 18 which is integrally connected to the inner iiange of the downwardly 'facing channel 17, and a second inclined leg portion 19 integral ly connected to the leg portion 18. The first inclined leg portion 18 inclines inwardly and downwardly at a rst acute angle relative to the vertical leg 14. The second inclined leg portion 19 of the inclined leg of the water cant 13 inclines inwardly and downwardly from the lower end of the iirst inclined leg portion 18 at a second acute angle which is a greater angle than said iirst acute angle. As illustrated in FIG. 2, the aforementioned first acute angle between the first inclined leg portion 18 and the vertical leg 14 is approximately 10. The aforementioned second acute angle between the second inclined leg portion 19 and the vertical leg 14 is approximately 45.

Integrally formed on the lower end of the second inclined leg portion 19 is a horizontal ange or extension 20 which is adapted to be secured to the roong deck 2 x 4, 11 by any suitable means as by a plurality of 1" galvanized rooting nails 21 which are disposed at predetermined center to center distances, as for example l2. The flange 20 is integrally connected to the lower end of the second inclined leg portion 19. The ange 20 is bent upwardly through an acute angle from the plane of the inclined leg portion 19 and is disposed substantially perpendicular to the outer vertical leg 14.

The numeral 22 designates each of the various roofing plies which form the built-up roong covering. The roofing plies 22 are overlaid in the usual manner by a layer of gravel bitumen 23. As shown in FIG. 2, the plies or layers of roofing material 22 are laid over the water cant flange 20, and they extend upwardly toward the edge of the roof, over the cant inclined leg portion 19, and into engagement with the cant inclined leg portion 18. It will be seen that the outer edges of the layers or plies of roofing material 22 do not extend to the upper end of the cant inclined leg portion 18 and that they do not have to be trimmed off iiush with the end of the inclined portion 18.

The numeral 24 generally designates an elongated external metal fascia which may be made from any suitable metal, as for example extruded aluminum. The fascia 24 comp-rises the vertical body portion which is in the form of a vertical plate. The lower edge of the fascia body por tion is bent downwardly and outwardly to provide the inclined ange 26, at the lower outer end of which is integrally formed the folded-over or U-shaped portion 27 and the integral iiange 28 which slopes upwardly and inwardly. The

flanges

26 and 28 and the U-shaped portion 27 comprises a drip hook configuration or channel which is adapted to receive and engage the drip flange 16 on the lower edge of the cant outer leg 14, as explained more fully hereinafter.

As best seen in FIG. 2, the upper end of the fascia body portion 25 is rolled or folded over inwardly as indicated by the numeral 29. The extreme upper edge of the fascia body portion 25 is further turned downwardly and then outwardly toward the fascia body 25 to provide a hook coniiguration which faces outwardly and which includes a support lip 30 that extends outwardly under the rolled over portion 29.

The sealer strip is generally indicated by the numeral 31, and it may be formed from any suitable material as, for example, extruded aluminum. The sealer strip 31 includes the upper body portion 32 which is integrally connected at its upper end with the flange 33. The flange 33 is disposed at an obtuse angle relative to the upper surface of the sealer strip upper body portion 32. The upper edge of the flange 33 is folded over inwardly and then downwardly to form a downwardly facing hook or U-shaped channel. As shown in FIG. 2, the hook on the upper end of the flange 33 is adapted to be received within the hook formed on the upper end of the fascia member 24. The lower edge of the outer arm 35 of the lastmentioned hook is adapted to engage the upwardly facing lip 30 on the hook on the upper end of the fascia member 24. The lower body portion of the sealer Strip 31 is designated by the numeral 37. The sealer strip upper -body portion 33 is joined to the lower body portion 37 by a longitudinally extended indentation which provides a first sealing ridge 36 for sealing engagement with the roofing material plies 22. A second longitudinally extended indentation is formed along the lower end of the sealer strip lower body portion 37 to provide a second sealing ridge 38. The numeral 39 designates the up-turned lower edge of the sealer strip 31.

The seaer strip 31 is provided with a plurality of longitudinally spaced apart, prepunched holes 40 for the reception of sealing grommets 41 and l stainless steel slotted, hex washer head screws 42. The grommets 41 may be made from any suitable material as, for example, neoprene.

In use, the roof edge structure of the present invention is mounted on a roof stiucture by first installing the water dam or cant 13. The cant 13 is nailed by means of the nails 15 to the edge or side of the roof. The cant flange 20 is then nailed by a plurality of nails 21 to the top of the roof structure. The building material plies 22` are then overlaid over the cant

inclined leg portions

18 and 19. As shown in FIG. 2, the plies 22 do not extend to the upper end of the inclined leg portion 18. The fascia member 24 is next mounted in place with the inwardly and upwardly directed fiange on the lower end thereof in engagement with the fiange 16 on the lower end of the cant body portion 14. The sealer strip 31 is then mounted in the dotted line position 43, shown in FIG. 1, with the hook on the upper end thereof inside the hook on the upper end of the fascia member. Sealer strip 31 is rotated downwardly to the full-line position shown in FIG. 2, so that the sealer strip is pivoted around the upper end 17 of the cant body portion 14. Simultaneously, the lower end of the sealer strip flange 33 engages the inner face of the fascia member body portion at the joint edge or pivot edge 45, as shown in FIG. 2, and continued downward movement of the sealer strip 31 moves the fascia member 24 downwardly, and the upper end thereof inwardly, and the lower end thereof outwardly so as to bring the flange 28 of the hook on the lower end of the fascia member 24 into engagement with the rear side of the flange 16 on the lower end of the cant body 14. The sealer strip 31 is attached to the cant inclined leg portion 19 by a plurality of sealer grommets 41 and the sealer screws 42. A nail is thrust through the prepunched holes 40, which are used as guides for the nail, and the nail is used to punch a hole 44 through the cant inclined leg portion 19. The screws 42 are threadably secured in place in the

holes

40 and 44 by any suitable means as, for example, by a hand screwdriver or a power-operated torque wrench. It will be understood that the sealer grommets 41 would be squeezed into the holes 40 in the sealer strip 31 to seal the roofing material about these holes. It will also be understood that the two sealing

ridges

36 and 38 provide a sealing barrier against snow or water which may be forced by winds up the inclined surface of the roofing material on the cant leg 19.

The fascia members 24 may be made in any length as, for example, in lengths. The adjacent ends of the fascia members 24 may overlap each other or they may be connected by suitable splice plates as indicated by the numeral 46 in FIG. l. The fascia members 24 are free to expand and contract longitudinally, and they are free to slide relative to one another over the splice plates 46, or over the overlapped ends if the overlapping structure is employed. The splice plates 46 may be provided with a configuration consistent with the configuration of the roofing edge as, for example, at a corner of a roof structure the splice plate 46 may be angularly formed.

While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change.
