Referring to the drawings in more detail:

The reference numeral 1 generally indicates a covering for a building structure having an otherwise exposed surface 2, such as a roof or outside wall. The surface 2 is here illustrated as wood, however, it is to be understood that any building surface which is adapted to receive an anchoring member such as a screw or nail is suitable for receiving the covering 1. A plurality of shingle assemblies generally designated 3 cooperate to produce the covering 1 and, in the illustrated example, each assembly includes a substantially rhombus or diamond-shaped integral lower sheet metal shingle 4 having a substantially planar body 5 partially resting against the surface 2. It is to be understood that with the possible exception of edge shingles (not shown) all the shingles making up the shingle assemblies 3 are identical to the lower shingle 4. However, for the purpose of facilitating this description other terms and reference numerals appearing hereinafter will be used to describe the shingles located adjacent to the lower shingle 4 and interlocked therewith. The body 5 has a first upper side edge 6 and a second upper side edge 7, the edges 6 and 7 respectively sloping downwardly and outwardly in opposite directions from a central point 3 therebetween.

The upper side edges 6 and 7 each have a continuous forwardly and downwardly turned upper flange respectively designated 9 and 10 which are substantially parallel to and spaced from said body and have

ends

11 and 12 respectively substantially abutting each other adjacent the central point 8. The upper flanges 9 and 10 each have a continuous lower or outer lip portion respectively designated 13 and 14 extending downwardly therefrom and oflfset toward but spaced from the shingle body 5 forming

shingle flange shoulders

15 and 16 therebetween.

A pair of

side shingles

17 and 18, which as noted above are identical to the lower shingle 4 each have a substantially planar body respectively designated 19 and 20 with a

side corner

21 and 22, in the illustrated example, having a blunt outer end 23. The

bodies

19 and 20 respectively have

upper side edges

24 and 25 and

lower side edges

26 and 27, with the upper and lower side edges of each body sloping upwardly and downwardly in the same lateral direction from the

respective side corners

21 and 22. The

lower edges

26 and 27 each have contiguous rearwardly and upwardly turned

lower flanges

28 and 29 terminating at the upper ends 30 and 31 thereof facing the

respective corners

21 and 22. The ends 30 and 31 are positioned in substantially abutting relation and are respectively spaced from the outer end 23 of the

respective corners

21 and 22. The

upper side edges

24 and 25 each have contiguous forwardly and downwardly turned

upper flanges

32 and 33 terminating at the

lower ends

34 and 35 thereof facing the

respective corners

21 and 22 in substantially abutting relation and spaced from the outer ends 23 of the

respective corners

21 and 22.

The

lower flanges

28 and 29 and

upper flanges

32 and 33 respectively have

outer lip portions

36, 37, 38 and 39 offset toward but spaced from the respective

side shingle body

19 or 20 and forming side

shingle flange shoulders

40, 41, 42, and 43 therebetween. The lower shingle upper flanges 9 and 10 are respectively received between the side shingle

lower flanges

28 and 29 and the

bodies

19 and 20 with the

respective flange shoulders

15 and 40, and 16 and 41 engaging forming a water resistant, interlocking seam structure 44 therebetween, FIGURE 6.

The

respective corners

21 and 22 overlap each other as best illustrated in FIGURE 3 and, as noted above, the respective side shingle upper flange ends 34 and 35 and the respective side shingle lower flange ends 30 and 31 substantially abut each other. The corners and abutting ends cooperate to form a stable, shingle positioning, water resistant joint structure 45 between the

side shingles

17 and 18.

An upper shingle 46 which is identical to the lower shingle 4 and

side shingles

17 and 18 has a body 47 adapted to partially rest against the surface 2 in the manner of the lower shingle 4. The upper shingle body 47 has first and second

lower side edges

48 and 49 respectively sloping upwardly and outwardly in opposite directions from a central point in the manner of but reversed from the edges 6 and 7 of the lower shingle 4. The

edges

48 and 49 also have continuous rearwardly and upwardly turned flanges 49 terminating in end abutting relation adjacent the central point and having continuous outer lip portions extending upwardly therefrom and offset toward the body 47 in the manner of, but reversed from, the upper flanges 9 and 10 on the lower shingle 4. It is to be understood that the upwardly turned flanges (not shown) of the upper shingle 46 is adapted to be received against the side shingle

upper flanges

32 and 33 in the space 50 provided between the

upper flanges

32 and 33 and the

side shingle bodies

19 and 20. The side shingle upper and lower

flange lip portions

36, 37, 38 and 39 each have a beveled terminus 51 adjacent the respective

side shingle corners

21 and 22.

A pair of identical supporting

nail tabs

52 and 53 are each preferably of integral sheet metal construction and of polygonal shape and have parallel upper and

lower edges

54 and 55 and

parallel side edges

56 and 57. The

edges

54 and 57, and the

edges

55 and 56 respectively form oppositely disposed

corners

58 and 59 in the shape of acute angles and the

edges

54 and 56, and 55 and 57 respectively form oppositely disposed corners 60 and 61 in the shape of obtuse angles. The

nail tabs

52 and 53 each include an upper planar tab body portion 62 and a lower planar tab body portion 62' parallel to the portion 62 and offset therefrom forming a tab shoulder 63 therebetween. The tab upper and

lower edges

54 and 55 respectively have an integral flange 64 extending outwardly therefrom in the direction of the opposite tab body portion and turned toward the opposite tab body portion forming elongated upper and

lower tab troughs

65 and 66. The

tab troughs

65 and 66 are crimped at 67 and 68 adjacent the acute

angled corners

58 and 59 respectively closing one end thereof.

Extensions

69 and 70, which would otherwise extend laterally outwardly of the nail tab after the formation of the tab trough, are bent around the crimped end at 67 and 68 adding structural strength to the respective trough formations. Nail receiving openings 71 and 72 are oppositely positioned substantially in the center of each of the nail

tab body portions

62 and 62.

The

nail tabs

52 and 53 are oppositely positioned adjacent the

side shingle corners

21 and 22 in side edge abutting or juxtaposed relation. The lower troughs 66 respectively receive a part of the side shingle upper

flange lip portions

38 and 39 and the beveled terminus 51 on each of the lips is located adjacent the respective trough crimp at 67 or 68. The tab shoulders 63 extend over the

upper edges

6, 7, 24, and 25 of the lower shingle 4 and

side shingles

17 and 18 whereby the tab upper body portions 62 rest against the shingle receiving surface 2. Suitable fastening members, in the illustrated example nails 73, extend through the upper tab openings 71 and into the surface 2 for securing the

tabs

52 and 53 to the surface 2 whereby the shingles are supported in proper respective position thereagainst.

Referring to FIGURE 8, a blank 74 is illustrated which after flange bending forms the shingles. The blank 74 is preferably produced from sheet metal in a single punching operation and includes

side notches

75 and 76 for forming the

side corners

21 and 22 and upper and

lower notches

77 and 78 which permit the upper and lower flanges to be formed in central point abutting relation. The fold lines for forming the flanges are indicated at 79 and 80.

The shingle assembly described above produces an interlocking seam and joint structure which is substantially water impervious but yet permits a small quantity of ventilating air to pass through to the shingle receiving surface 2 to aid in evaporating condensate or the like forming thereon. The overlapping and abutting structure of the side shingle corners and the interlocking seam along the shingle edges provide a positive positioning of the shingles as they are assembled to prevent unwanted lateral and vertical shifting with respect to the lower shingle 4 prior to the installation of the

nail tabs

52 and 53 and the upper shingle 46. The various parts of the shingle assembly are easily produced and installation proceeds rapidly since the engaging shoulders on adjacent shingle flanges urge the shingles into correct relative positions. It is to be understood that although diamondshaped shingles are illustrated herein, this invention is adaptable to other shingle shapes, for example squares or triangles or various combinations. It is to be further understood that while one form of this invention has been illustrated and described it is not to be limited to this specific form or arrangement of parts herein described and shown except in so far as such limitations are included in the claims.
