Application January 30,1937, Serial No. 123,110 -s Claims. (01. 108-17) This invention relates to a new and improved strip roofing material.

One of the features of this invention consists in providing a covering for a roof, which is 5 simple in construction, easily applied and having minimum overlap. A further feature of the invention consists in providing a covering for a roof which, while not truly a shingle, resembles a shingled roof in appearance without the at- 10 tendant disadvantages sometimes found in the common shingle. Another feature of the invention consists in providing a holding down clip for holding down the weather edge-of an overlying element, said clip being welded to its ll supporting element. Although'the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, and the- 20 manner in which it may be carried out, may be better understood by referring to the following description taken in connection with the accompanying drawing forming a part thereof, in which:

25 Fig. 1 is a view of a house having a roof with the improved roofing;

Fig. 2 is a plan view, showing how the roofing material is applied;

Fig. 3 is a section through the roof on the line 30 3-3 of Fig. 1;

Fig. 4 is a plan view of a section of roofing material showing another form; and

Fig. 5 is a section of the roofing material showing a form of clip.

35 In the following description and in the claims various details will be identified by specific names for convenience, but they are intended to be as generic in their application as the art will permit. I

Like reference characters denote like parts in the several figures of the drawing.

In the drawing accompanying and forming part of the specification, specific disclosures of the invention are made for purposes of explana- 46 tion, but it willbe understood that the details may be modified in various respects without departure from the broad aspect of the invention.

Referring now to the drawing and more particularly to Fig. 2, the roofing material com- 50 prises preferably a strip of relatively long and narrow material, preferably metal, forming a rectangular-shaped roofing strip l. The lower edge 15 of this strip may be notched as at 2, the purpose of which will be explained hereinafter.

66 Intermediate the notches 2 this edge of thestrip A may be first applied to the lower edge of the may be bent to form a raised flange or bead 3 running along to the weather edge of the strip and having a lipportion 4 lying in substantially the same plane as the main body of the covering material I.

Adjacent the upper edge l6 of the strip I may be attached fastening clips 5. These clips may comprise suitable flexible wire or strip metal soldered, brazed or welded to the covering strip adjacent their middle point 6 and having the 10 end free so that they 'may be bent as desired for the purpose to be described hereinafter. Perforations 9 may be provided adjacent the edge l6 through which fastening nails III are adapted to be passed for securing the roof covering to the supporting surface ll of the roof of the building to be covered.

For convenience in shipping, the length of these strips must necessarily be limited and therefore in covering a roof it will be necessary to have several strips running lengthwise of the roof in the same course. Suitable overlap must be provided between the ends of these strips. For this purpose a flat portion of the strip, as shown at 8, extends beyond the body or main portion of the strip. Thus, the next strip, as shown in Fig. 2, may be attached over this flat extension part to provide a weathertight joint. To lay this roofing, the usual flashing strip 0 roof. The roof will, of course, be laid from the bottom and each course may be laid from left to right when working on the roof. If desired, a, strip roofing elementl may be used as a flashing strip, the flanges 3 and 4 first being cut off. Nails I0 may be passed through the holes 9 into the supporting surface. This flashing strip A may be bent around the lower edge of the roof and the lower edge secured in place by nails 20, as indicated.

The course of roofing strips, denoted by B, is then laid over course A, the clip member 5 of course A being bent around the flanges 3 as indicated. Thereafter, the succeeding courses C, D, etc, will be laid in a similar manner, care being taken to stagger the notches 2 in the adjoining courses. Each course may-be started with a complete new strip or with a left over piece of strip which has been cut to finish a preceding course. It is only necessary that the notches 2 in adjoining courses should be staggered and the weather ends should be properly held down by the clips 5.

A plain, flat strip may be used as a hip or ridge strip, or, if desired, the upper course indicated by X may be bent over to form the hip or ridge strip.

The rolls or flanges 3, at the lower edge of each strip of covering material, interrupted by the notches 2, give the appearance of the r'egu-, lar exposed end of a normal shingle. To accentuate this effect, I may provide a large corrugation H, as in Fig. 4, extending from the notch 2 substantially at right angles to the longitudinal edge of the covering strip l and extending preferably to the upper edge of the strip. This corrugation may constitute either a hill or valley on the surface, the primary purpose being to simulate the spaces ordinarily present with the regular shingle.

If desired, the strip roofing may be corrugated with the corrugations in Fig. 4 running up and down the roof, these corrugations being smaller than the large corrugations I. If desired, the lower edge ii of the strip may be made irregular to obtain the random effect of shinglesof variable length, as in Fig. 4.

If desired, instead of attaching the clip to the strip at a point where it will be covered by the overlying course, I may form it as a flat platelike member as illustrated in Figs. 4 and 5, the clip here being denoted by H, the lower part being welded or otherwise integrally secured to the strip and its upper edge 2| free but lying flat against the strip roofing.

In holding down the lip 4 of an overlying course, I either bend up the free portion 2| of the clip I! and then bend it down to grip the edge of the overlying course of covering mate'- rial, slide the covering material under the free portion 2| of the clip. The clips I! may be located at any point. along the length of the covering strip and the free portions 2| are long enough to engage any of the lips l of the ir-. regular lower edge in Fig. 4.-

Thus, it will be seen that I have provided a sheet metal roof having a pleasing'appearance and which may be made to appear not unlike an ordinary shingled roof. The complete structure presents a fully covered 'imperforate. roof which'is impervious to water.

The present roof is considerably less expensive than a corresponding real shingled roof in that it is only necessary for adjoining courses to overlap in contrast to the requirement, in the ordinary shingled roof, that each course overlap the adjoining course and the course once removed. Furthermore, the provision of positive holding down clips permits the use of a lighter metal and yet insures freedom from flapping of the lower edges of the strips'in thewind.

The clips may be welded in a simple manner 7 by well known automatic welding machinery without making any 'holesin the roofing strips. Furthermore, the welding of separate clips obviates the dangers of crystallizing the metal which might occur if parts of the roof strips themselves were bent for holding down the weather edges:

Furthermore, the roofing is easy to manufacture, easy to ship, and easy to lay. 'The strips may be made sufficiently short to avoid anytrouble from contraction and expansion. The corrugated form is especially advantageous in this regard, thecorrugations acting in an accordionlike manner to take up expansion andcontraction. The striprooflng may be made -of any,

suitable material, such as copper, zinc, stainless steel, etc. or it may be made of suitable nonmetallic waterproof sheet material having the proper structural characteristics. The thickness or gauge of the metal will, of course, vary. depending upon the character of the material and the strength desired. a

As an illustration, in the case of copper, 30

gauge thickness may be used. With this weight of copper, the weight per square foot of covering, according to the invention, may run about 10 ozs. as against 16 ozs. with a similar roof of individual shingles.

It will benoted from the drawing that either with plane stock, as in Figs. 1, 2 and 3, or with corrugated stock, as in Figs. 4 and 5,-the raised flanges or beads 3 stand out from the generally flat body of the strip and from-the lip portions 4, giving an illusion of thickness to the strip.

Furthermore-in either case, the substantially fiat thin sheet metal bodies lie substantially flat against the underlying supporting surface, mak-' 1.
