Filed March 18, 1952 INVENTOR HOMER D. WENGER m ATTORNEYS Patented Apr. 27, 1954 UNITED STATES PATENT OFFICE ROOF EDGE TRIM Homer D. Wenger, Pandora, Ohio Application March 18, 1952, Serial No. 277,097
This invention relates to new and useful improvements in edging strips particularly for flat roofing. I More particularly the invention relates to a structure formed from a single sheet of metal which is capable of exercising the function of a flashing, a parapet, a roof edge trim and when desired also serves as a ventilating louvre.
A primary object of this invention is to provide a roof edge for flat roofs which structure has protective as well as decorative characteristics.
A further object of the invention is to form a roof edge strip from a single sheet of metal or equivalent resilient sheet material which strip prevents the entry of moisture to the interior of the building structure and provides a convenient drain for the passage of the condensed moisture from the structure.
Another object of the invention is to provide from a single sheet of metal a roof edge strip for flat roofs which strip may embody a parapet, a flash and a drain-off portion.
An important object of the invention is to provide from a single sheet of metal a roof edge strip which may be sprung over a flat roofing to provide the interior of the structure with ventilation while protecting the building from the entry of undesired moisture.
These and other objectives of the invention will become apparent during the course of the following detailed description, taken with the drawings wherein is shown a. preferred embodiment of the invention.
Figure 1 is a perspective view of a building structure embodying the roof edge of invention;
. Figure 2 is a view partially in section illustrating the attachment of the roof edge of invention to a building structure;
Figure 3 is a fragmentary front elevational view illustrating the formation of louvres integral with the roof edge strip of invention; and
Figure 4 is a view partially in section illustrating a modification of the strip of invention.
Referring to the drawings there is indicated generally at I in Figure 1 a building structure having a flat roof 3 (Figure 2) and a roof edge strip indicated generally at 5 is secured thereon. The roof edge strip 5 comprises, as shown more clearly in Figure 2, a horizontally extending anchor portion or flashing I secured to roof boards 9 beneath the material of the flat roof 3 and supported on joists II.
Extending upwardly from the anchor portion 1, forming an integral portion of the structure 5 and shown in the shape of an inverted U is a iii 3 Claims. (01. 1085-26) parapet portion I4 from which there downwardly depends an outer skirt portion l5 substantially parallel with the building wall. This portion I5 is adapted to close the open ends of the spaced joists II of the roof structure. The lower portion of the skirt I5 terminates in a trough portion I! having an aperture I9 in the bight thereof and extending from the inward side of portion I1 and parallel with the anchor portion I is a fascia 2i. The fascia 2| is secured to sheathing 23 and for thispurpose the fascia 2I is conven iently provided as at 25 with nail holes through which nails 21 may be driven.
As shown in Figure 3 there is formed in the face of the dependent skirt portion I5 a ventilator indicated at 29 comprising louvre portions 3|, 33 which define, respectively, with the skirt portion I5 longitudinal slots 35, 3! (Figure 2). The lower portions 3|, 33 are formed integral with the skirt portion I5 as shown in Figure 3.
Figure 4 illustrates a modified form of the fascia of the structure of invention wherein the fascia is of relatively short length as shown at M. Fascia 4| is secured to the sheathing 23 through nail holes by nails 41. With this arrangement, which is particularly useful when the anchor portion 1 is of great length in order to permit it to pass beyond the building wall, the metal sheet roof edge strip 5 may be readily sprung over the joist II, roof boards 9 and sheathing 23 to form a complete edge trim for the building structure.
It will be understood that the roof edge strip 5 may be of any suitably desired length and may comprise a number of short lengths joined together with end to end relation in order to provide a continuous length of edging for the building structure. The juncture of the strips Whether in the central portion of the building or at the corners thereof may be sealed if desired although the same is generally unnecessary since the strip is adapted to drain to the aperture I9. It may be noted however that a rubber sealing strip between the junctures is effective to increase corrosion resistance.
It should also be noted that th provision of the slots 35, 3! renders the roof edge strip somewhat flexible and facilitates mounting of the single metal piece over the building structure.
When mounted in position on a flat roof as shown in Figure 1 the flashing l prevents the entry of moisture through the roof, while the parapet which may be of any desired height or contour, affords protection to the roof top from rain, snow, and so forth. The portion 2 I prevents entry 3 of water and moisture from below, while rain and snow which may be driven throu h the slots 35, 31 will be readily collected by the trough IT.
The stripping 5 also may be clearly adapted for roofs having a parapet in a building structure and in this case it is only necessary that the sheet metal be formed to enclose the parapet and have sufiicient resiliency to encompass the framework of the roof of the building. An ordinary sheet metal will normally be satisfactory for this purpose.
It will be understood that this invention is susceptible to modification in order to adopt it to different usages and conditions and accordingly, it is desired to comprehend such modifications within this invention as may fall within the scope of the appended claims.
1. In combination, a fiat roof having the roof boards and sheathing thereof secured to opposed sides of spaced joists, an edge stri comprising an integral body of resilient sheet material having an anchor portion secured to said roof boards, a fascia secured to said sheathing,- and a facing portion joining the outward ends of said anchor portion and fascia and spaced therefrom and extending above said roof portion to form a para pet and below said sheathing to form a trough,
and covering the edge of the roof, said facing portion having louvreo ening's therein. I
2. The combination setfortli in claim 1, with 4 said trough portion having an aperture in the bight thereof.
3. In combination, a flat roof having the roof boards and sheathin thereof secured to opposed sides of spaced joists, an edge strip comprising an integral body of resilient sheet material and comprising an anchor portion secured to said roof boards, a fascia secured to said sheathing, and the facing portion joinin the outward ends of said anchorportion and said fascia and spaced therefrom to cover the edge of said roof, said facing portion having a parapet extending above said roof boards and a trough depending below said sheathing.
