Claims. (Cl. 108—17)

This invention relates to metal roofing and uldinK and more particularly to a metal root Xng which can be attached without the use °^f Inmetal roofs^t is the usual practice to employ an entire sheet of the metal and attach the same to the sheathing by means of nails. The ex pansion and contraction of these large: meW sheets causes bulging, enlarges .the nail ^aresults in leaks in the roof after a short period.

It is an object of this invention^{to e}™^at®. disadvantage by employing ^atl\^e17 T ^r.°„ sheets of metal and attaching them by ci imping it ba further object of the invention to provide pre-crimped sheets of metal which may be attached after the sheathingjs mp ace and which will be firmly held to the sheathing at a ‘“Sseand other ferred^constructions, in which: ,.

conforming in shape to the roll 14, on both upper and lower sides. The covering 19 may be put on by sliding on from the end after the ridge roll has been nailed in place. The sheathing 12 is then nailed down to the rafters 10 with the metal lock bars 20 placed under the lower edge of the sheathing. The metal lock bars 20 (best shown in Fig. 3) comprise in general a zshaped section having a vertical leg 21 of length equivalent to the corresponding portion of the sheathing 12, the upper end thereof being curved back and under to form a reverse curve 22 and a lock notch 23. . , , ,.

The shingle 25 may be of any convenient length and may be formed directly on the job. As shown in Fig. 3, the shingle 25 comprises a fiat portion 26 having at one side a raised semi-circular portion 28 and is bent back, as shown at 29, at the other side thereof to form a reverse curve having a notch 30. The formation of the bent back portion 29 conforms in shape to that of the portion 22__23 of the metal lock bar 20, the notch 30 fitting into the notch 23. The roll 28 fits beneath the notch 30 of the next shingle above to form a fastening for the shingle. This construction is best shown in Fig. 4. The shingle adjacent the ridge roll is given a curve to correspond with the curve 17 to lock that shingle in place beneath the ridge roll. ₈5

At the intersecting portions of the roof, such as shown in Fig. 5, provision is made for the introduction of valleys, the construction being most 6 of Fig. 5, dearly illustrated in Fig. 6. The valley 33, shown in Figs. 5 and 6, comprises a lower piece 35 bent upwards at the ends and turned back to form an inverted U—36 having its open end towards said member 35. The corresponding ends of the shingle are also bent in a U-shape, as shown at 38, the two free legs of the U’s overlapping each other to make the construction waterproof. It will be noted that this piece may also be inserted from the end of the roof after all of the shingles have been laid.

If desired, the edge of the roof may be finished • with a metallic gutter, similar to the valley construction described above.

A variation of the form of shingles shown m Fies 1 to 4, inclusive, is shown in Figs. 7 and 8. In this form of construction there is employed specially milled sheathing shown at 40, and

1,963,583 having a projecting end 41 shown in Fig. 8, and a notch 42 in said projection for the reception of the roll portion 30 of the shingle 25. The construction of the shingles is identical and the fas5 tening together is done in a similar manner.

This form of construction eliminates entirely the metal lock bar 20, but increases the cost of construction to the extent of having to have the boards 40 specially milled. The construction 10 shown in Figs. 1 to 4, inclusive, is preferable in that it has a little greater strength than the form shown in Figs. 7 and 8.

The valley 35 further preferably includes a top fitting portion comprising the upper end of the 15 Plate 35 having converging side edges curved to form locking hooks 44 seatable on the curved upper end edges of shingles 25 as illustrated in Fig. 9.

The plate 35 is a slit transversely on each side 20 as at 46, to define the ends of the U-shaped edge portions 36 and permit bending of panel-like portions 48 of the plate to snugly overlie adjacent shingles. The pointed ends 50 of the panels thus extend laterally from the valley trough over the 25 roof.

The curved edges of the valley top fitting extend beneath the ridge roll cover, as suggested in Fig. 5.

It will thus be seen that applicant has provided 30 a relatively simple form of metal shingle which may be used either for roofs of houses or for sidings, and which has provision for valleys and fastening means.
