FASCIA SYSTEM ron A FLAT ROOF BACKGROUND OF THE INVENTION The instant invention is in the field of building structures, and relates specifically to the structure of the marginal edge portion of a fiat roof deck wherein there is provided a waterdam or cant extending along the periphery of the roof deck, the roof itself comprising a plurality of layers of roofing material overlaid with a layer of gravel bitumen. A generally vertically disposed strip of material such as aluminum or the like, commonly known in the trade as a fascia, extends longitudinally along the waterdam or cant, covering the visible surface thereof and thus forming a pleasing appearance. The structure also includes a liner member extending along the upper edge of the fascia and overlying the layers of roofing material which project over the inclined waterdam or cant, and anchor means having a hook portion for easy and effective locking engagement against a marginal edge of the fascia to retain the fascia and the liner in predetermined position with respect to the roof deck. The construction describes a simple and easily installable system for the marginal edge of a roof deck, providing a pleasing appearance and at the same time insuring against seepage of water or gravel bitumen material down the face of the building.

In prior art constructions known to applicant, a fascia strip is provided, together with means for securing and holding the fascia strip in place and preventing water leakage down the face of the building, wherein the securing members extend the entire length of the fascia strip, with screws spaced apart along the length of the securing member to fasten the assembly to the roof deck. In addition to the fact that these constructions in some instances do not provide adequate sealing against water leakage, they are generally quite difficult to install on the roof, principally because of the fact that the securing or anchoring member is of such length as to be cumbersome and difficult to handle and maintain properly positioned while being screwed to the roof deck. Applicant's structure on the other hand utilizes anchor means which are relatively small, an ideal size being about 2 inches wide, which are provided with a hook portion easily engageable with a projecting head on the fascia and which because of their size are more conveniently handled for installation of the system on the roof. In addition, the provision of the interfitting fascia and liner members provides a waterproof roof edge construction which obviates the possibility of unsightly water stains down the face of the building.

Other objects, advantages and meritorious features will more fully appear from the following specification, claims and accompanying drawings, wherein:

FIG. I is a perspective view of the marginal edge of a roof deck showing my improved fascia system installed thereon;

FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1; and

FIG. 3 is a partial cross-sectional view similar to FIG. 2 showing a preferred form of my fascia system.

Referring now more particularly to the drawings, there is shown the marginal edge portion of a roof deck for a building, the top of the building sidewall being shown at in FIG. 1 sunnounted by a cap 12, the base roof deck of the building 14 being in alignment with the wall cap 12. Overlying the base roof deck 14 are a plurality of layers of roofing material generally indicated by the numeral 16 surmounted by a layer of gravel bitumen material 18. Extending along the marginal edge of the roof and secured to the cap member 12 as by means of nails or the like 20 is a waterdam or cant 22 having a generally vertical portion 24 extending above the roof deck and an inclined portion 26 having a horizontal edge portion secured to the roof by fastener 20. The waterdam or cant 22 extends completely around the periphery of the roof, and the members shown may be made out of galvanized metal or the like as shown, or may be made out of wood. The gravel bitumen layer 18 terminates substantially at the lower edge of the inclined cant 26 while the layers of roofing material continue on up the inclined surface, with the topmost layer extending over the peak of the cant and downwardly overlying the vertical surface a short distance.

An elongated fascia strip 28 is provided which is disposed generally vertically overlying the upright portion of the cam 22, and having a slightly outwardly flared lower end 30 shaped to define an upturned channel which embraces the lower extremity 32 of the cant, which is slightly outwardly flared to cooperate with the channel on the fascia strip. The inclined lower end of the fascia strip provides a grip edge and the relationship between it and the lower edge of the cant provides a simple connection therebetween. Referring specifically to FIG. 2, the fascia strip 28 is provided adjacent its upper end with a pair of spaced-apart inwardly directed projecting

portions

34 and 36 respectively, the lower portion 36 characterizable as a projecting lip which engages the folded over edge of the upper layer of roofing material shown at 16a, while the upper portion 34 terminates in a marginal bead 38 extending therealong. The fascia strip 28 is preferably made out of sheet metal, such as extruded aluminum or the like which is provided in relatively long lengths arranged in end-to-end relation along the roof edge, there being provided joint members (not shown) of similar cross-sectional shape which overlie the marginal edges of adjacent fascia strips and conceal the slight space left therebetween. In some instances, the joints might be eliminated, and the fascia strips 28 made to overlap each other.

The projecting

portions

34 and 36 of the fascia strip 28 define a generally U-shaped channel within which there is positioned the upper end of ali'nerflashing strip 40, which conforms to the shape of the fascia strip channel and is additionally provided with a lower end portion overlying the upper layer of roofing material 16a. The liner flashing strips 40 are disposed in end-to-end relation, and are of appreciable length, preferably each being equal to approximately one-half the length of the flashing strip 28, for reasons to be described hereinafter. Spaced apart along the roof edge assembly are a plurality of anchor means or clips 42, which are preferably made out of aluminum or the like, each of the clips 42 being relatively narrow, say 2 inches or so, with respect to the length of the fascia strip and liner strip. The upper end of each clip 42 is generally hook shape, as shown at 44, terminating in a locking edge 46 which engages and locks against the upstanding shoulder of the bead 38 which runs the length of the fascia strip 28. Adjacent the hooklike portion 44, the clip 42 exhibits a projecting intermediate portion 48 which projects into the channel formed by

fascia portions

34 and 36 and bears against the liner member 40. Extending downwardly and away from the upper end of the clip, there is a lower end portion 50 which overlies the correspondingly shaped portion of the liner portion and maintains the liner in intimate contact with the roofing material 16a. The marginal edge of the clip 42 is displaced from the plane of the clip in a generally triangular configuration as shown at 52 to provide a more rigid edge which bears against the roofing material 160 and holds it securely in place. The lower marginal edge of the liner member 40 is correspondingly shaped to provide rigidity to that member, and insure bearing engagement against the roofing material throughout the length of the liner strip intermediately clip members 42. A securing means in the form of a screw 54 is utilized to secure the clip 42 to the cant 26, and hold the entire fascia assembly in proper position. The screw 54 is preferably made out of stainless steel or other suitable metal because of its properties of high strength and resistance to corrosion.

As can be seen from an examination of FIG. 2, with the lower end 30 of the fascia strip 28 hooked over the lower edge of the cant 22, the fascia strip upper end is positioned so that the projecting lip 36 engages against the folded over layer of roofing material, and with the fascia strip so positioned, the liner member 40 is inserted within the channel and extended over the inclined surface of the roofing material. One of the anchor means or clips 42 is thereafter installed to complete the assembly by engaging its hook 46 over the bead 38 on the fascia strip and then swinging the clip 42 in a clockwise direction until it assumes the position shown in FIG. 2. The stainless steel screw 54 may then be screwed through the roofing material 16 into the cant 26 to secure the entire assembly in place.

As can be seen from FIG. 2, with the parts assembled, the clip member 42 exerts a downward and inward force against the uppermost projection 34 of a fascia strip 28, in turn urging the projecting lip 36 into intimate contact against the uppermost layer 16a of roofing material. The fascia strip is thus positively held in position at its upper end, without exerting any appreciable force against the lower end 30 of the fascia strip and the interfitting edge 32 of cant 22. Therefore there is no possibility that the fascia strip 28 will be distorted nor that the lower end of the cant 22 will be pulled away from the cap member 12.

Referring now specifically to FIG. 3, there is shown a preferred embodiment of the elements forming the roof edge construction for use on a roof identical to that illustrated in FIG. 2 and previously described. The roof edge construction and the cant 22 are identical to that shown in FIG. 2, and a preferred fascia strip 60 is provided having a lower end portion (not shown) of identical shape as to the portion 30 of the fascia strip 28 previously described. Spaced from the upper end of the fascia strip 60 is an inwardly projecting lip portion 62 running the length of the strip of similar configuration to and for the same purpose as the projecting lip 36 on fascia 28. At its upper end, the strip 60 is shaped into a generally channellike portion 64 terminating in a marginal bead 66 as shown. A liner strip member 68 is provided similar in construction to the member 40, but shaped adjacent its upper end conforming to the shape of the fascia strip section 64 to interfit within the fascia member and extend downwardly away therefrom and overlie the roofing material 16a in similar fashion. A clip or anchor member 70 is provided, having a first end portion 72 of hooklike configuration embracing the bead 66 and in locking engagement against the bead shoulder as shown, an intermediate portion 74 extending between and interfitting in the recess formed by the

fascia portion

64 and 62 and retaining the liner 68 thereagainst, and an opposite end portion 76 of substantially identical shape to the end portion 50 of clip 42. Securing means in the form of a screw or the like 54 is utilized to fix the clip 70 to the cant 22, and retain the entire assembly in proper position with respect to the roof deck.

As stated above, the

fascia sections

28 or 60 and the

liner members

40 or 68 are of appreciable length, while the clips for

anchor members

42 or 70 are comparatively small. The dimensional relationships between the various parts of the assembly and purpose for such relationships will be described with reference to the structure shown in FIG. 3, it being understood that the same relationships apply to the structure shown in FIG. 2. The waterdam or cant 22 may be made of any convenient length, and as the roofing material extends upwardly over the inclined surface of the cant, the abutting edges of adjacent cant sections are covered by the roofing material, obviating any water leakage problems. The cant 22 as shown is well known in the industry, and does not form a part of the instant invention. Taking first of all the fascia strip 60, we will assume that such is manufactured of metal such as aluminum in lengths of feet, for purposes of illustration. According to the example, the liner flashing sections 68 would be manufactured with extruded aluminum or the like of about 5 feet in length. There would thus be provided two sections of liner for every section of fascia. As previously stated the anchor means or clips shown at 70 in FIG. 3 would be approximately 2 inches in length measured longitudinally of the fascia strip and liner member. When installing the liner member 68 into the fascia strip, a slight cap would be left between adjacent liners, and a clip 70 is hooked over the fascia strip bead and positioned to bridge the gap and overlie the space between adjacent liner members. The screw 64 is thereafter engaged through the clip, the layers of roofing material and the cant. However such screw does not pierce either of the adjacent liner members 68. In addition, substantially centrally along the length of each liner member 68 there is provided an additional slip member which is installed in similar fashion, the securing screw 54 for such clip extending through the liner member. Thus, while there is provided for each liner member 68 in effect three clips 70, one at each end of the liner member and one midway along its length, only one securing screw actually extends through the liner member 68. This results in the liner member being held in its proper relationship with respect to the fascia strip and roof deck at three points along its length, but being pierced by a screw at only one point, which provides for expansion and contraction of the liner strip due to changes in temperature without any tendency to coupling of the liner strips and without exerting any expansion forces against the securing screws 54 which might tend to loosen them. Adjacent abutting ends of the fascia strip 60 are also spaced apart slightly a predetermined distance to allow for expansion and contraction of the strips due to climatic changes without interference therebetween, the joints being covered by a cover plate or joint member (not shown) overlying the fascia strip.
