2 Claims.

My invention relates to roofs, and has for its principal object the provision of a relatively simple and easily practiced method of constructing a weather-proof roof from thin sheets of material,

5 either flexible or rigid, and which material may be in the form of rolls, or of plain or designed sheets or shingles.

A further object of my invention is to provide an improved method of assembling two or more layers of thin material to form an efficient covering or siding for the external surfaces of walls and the like.

Further objects of my invention are to provide an improved form of roof that involves the novel assembly of two or more strips, sheets or pieces of material of different widths, and which pieces of material are arranged so as to produce the desired amount of exposure of the assembled pieces, as well as the desired degree of head-lap,

and which latter is, due to the arrangement of the pieces of material, sufiicient to effectively prevent water, dust and the like from being forced by wind or otherwise upwardly between the overlapping portions of the strips or pieces of material that form the roof or siding.

My improved roof and method of laying same provides for a material increase of the head-lap coverage of roof covering strips, sheets and shingles, thus rendering the completed roof or siding no weather-proof to a maximum degree, without sacrificing the appearance of the completed roof or siding, and my improved method is comparatively simple and likewise comparatively inexpensive.

My improved principle of utilizing one wide sheet of material or shingle and a narrower sheet or shingle produces a multiple thickness roof that has much greater weatherproof effectiveness and is no more expensive in application than other types of multiple thickness roofs or siding.

With the foregoing and other objects in view my invention consists in certain novel features of construction and arrangements of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing, in which:

Fig- 1 is an elevational view of a portion of a roof formed of strips or sheets of material in accordance with my improved method.

Fig. 2 is a cross section taken on the line 2-2 of Fig. 1.

Fig. 3 is an elevational view of a portion of a roof constructed in accordance with my improved method from shingles of different widths.

Fig. 4 is a sectional perspective view of a modified form of roof constructed in accordance with my improved method.

Referring by numerals to the accompanying drawing, ID designates the roof boards of a roof having a pitch of approximately 45, but it will be understood that my improved method contemplates the construction of a roof covering on roofs of different inclinations and on the outer surfaces of vertically disposed walls and the like.

In producing the roof by my improved method from material such as composition roofing, and which is delivered to the user in rolls, a starting strip l l is laid longitudinally along the lower edge of the roof and applied to the lower portion of the exposed face of this wide starter strip is a narrower starter strip I2, the lower edge of which coincides with the lower edge of strip H. These starter strips are secured to the roof boards by nails and overlying the two starter strips is a strip I3 of roofing material, preferably, though not necessarily, of the same width as the starter strip H, and the lower edge of this first roofing sheet I3 coincides with the lower edges of the starter strips II and I2.

A strip of roofing material I 4 somewhat nar- I rower in width is now laid on the exposed face of the first roofing strip IS with the lower edge of said strip l4 spaced apart from and parallel with the lower edge of the underlying wider strip l3.

A second wide roofing sheet l3a that is approximately equal in width to that of the strip !3 is now laid with its lower portion overlying the upper portion of the narrow strip I4, and also overlying that portion of the sheet l3 between the upper edge thereof and the upper edge of the narrow strip I 4.

A second narrow strip of roofing material l4a approximately equal in width to the width of strip 14 is now laid onthe strip 13a between its upper and lower edges, and a third wide strip I31) is now laid with its lower portion overlying the upper portion of the narrow strip Ma, and the wide strip I3a. This alternate laying of wide and narrow strips continues to the ridge of the roof or to the upper end of the wall that is being covered and thus the entire structure comprises a plurality of wide strips and a plurality of narrow strips, the latter being laid on the wider strips with the upper and lower edges of the narrow strips, spaced apart respectively, from the upper and lower edges of the wide strips.

The exposed faces of the wide and narrow strips, and which are preferably uniform in width, constitute the exposure of the roof, and the upper portions of the strips or those portions above the exposure are generally termed the head-lap.

It will be understood that, as the wide and narrow strips are alternately laid in parallel relation, as described, said strips are secured to the roof boards by nails, and which latter are positioned so that their heads are covered by overlying portions of the strips.

Inasmuch as the narrow strips l4 and Ma are applied to the wider strips between their upper and lower edges, and the. lower portion of the succeeding wide strips overlies the upper portion of one of the narrow strips, the upper portion of each wide strip has a head-lap of substantial width formed by two layers of material, and which head-lap is essentialy efiective in providing a weatherproof joint.

In Fig. 3 I have illustrated a roof structure in accordance with my improved method and the covering elements being in the form of composition shingles. In this connection it will be understood that my invention contemplates the construction of a roof or siding from shingles or small sheets or pieces of thin material, either rigid or flexible, and of any desired size and shape.

In the construction illustrated in Fig. 3, rows of wide shingles or sheets of material 15 are combined with rows of narrow shingles or pieces of sheet material I6, the latter being laid on the wider shingles l5 with their upper and lower edges spaced apart from the upper and lower edges of said wider sheets or shngles.

In this form of roof or siding the wide and narrow starter strips I I and I2 are utilized along the lower edges of the roof or along the bottom of the wall to which the siding is applied.

In Fig. 4 I have illustrated a roof or siding that comprises a series of wide strips or shingles l1 and arranged between each pair of these wide strips or shingles is a pair of narrower strips or shingles l8. 7

Where this form of roof or sheathing is laid, one of the narrow strips or shingles l8 overlies the intermediate portion of the underlying wide strip, with the lower edge of the narrow strip or shingle spaced apart from the lower edge of the underlying strip or shingle to provide the desired exposures and a second narrow strip [8 is now laid over the upper portion of the first laid narrow strip or shingle with the lower edge of the second laid strip or shingle spaced apart from the lower edge of the first laid strip or shingle to provide the necessary exposure.

The second wide strip or shingle is now laid so that its lower portion overlies the upper portion of the second laid narrow strip or shingle and with the lower edge of the second wide strip or shingle spaced apart from the lower edge of the second laid narrow strip or shingle to produce the proper width of exposure.

This particular arrangement of forming a roof or siding is utilized where there is a considerable variance or difference in width between the wide and narrow strips, for instance, with a strip of material or shingle having a width of twenty inches the narrow strips or shingles would have a width of only ten to twelve inches.

In addition to the particular methods of laying a roof or siding as herein illustrated and described, it will be understood that my invention contemplates any arrangement of relatively wide and narrow strips of roofing material or shingles that are arranged alternately or semi-alternately with the narrower strips overlying the intermediate and upper portions of the wider strips and all of the strips being spaced so as to provide the desired width of exposure between the strips or shingles and likewise to provide sufficient headlap between the overlapping portions of the wide and narrow strips or shingles and thus producing a roof or sheathing that is highly efiective in resisting the ingress of water, dust and the like, and at the same time producing a roofing or shingle that presents a neat and pleasing appearance.

It will be understood that minor changes in the size, form and construction of the various parts of my improved roof may be made and substituted for those herein shown and described without departing from'the spirit of the invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. A roof or siding composed of two sets of separately formed alternately arranged strips of roofing material the strips of one set being substantially narrower than the strips of the other set, the narrower strips or shingles extending lengthwise of the wider strips or shingles on the upper portions of the upper surfaces thereof, with the lower edges of the narrow strips disposed a substantial distance above and parallel with the lower edges of the underlying wider strips or shingles to provide exposure, the upper edges of the narrower strips being disposed below and parallel with the upper edges of the underlying wider strips to provide a head-lap of suflicient width and the lower portions of the wider strips of material or shingles overlying and directly contacting the upper portions of the upper surfaces of the underlying narrow strips or shingles and those portions of the underlying wide strips that project above the upper edges of the narrow strips.

2. A roof or siding composed of two sets of separately formed strips of roofing material or shingles, the members of one set being substantially narrower in width than the members of the other set, one of the narrower strips being positioned on the upper face of one of the wider strips, so that the upper edge of said narrower strip is disposed below and parallel with the upper edge of the underlying wider strip, with the lower edge of the narrower strip disposed a pre-determined distance above and parallel with the underlying wider strip to provide the desired exposure, and the lower portion of each wider strip overlying and in direct contact with the upper portion of the underlying narrow strip, and also in direct contact with the upper surface of that portion of the underlying wide strip above the upper edge of the narrow strip to produce headlap of substantial width between the lower portion of each wide strip and the upper portions of the underlying narrow and wide strips.
