ROOFING Filed June 26, 1934 gill IHHHI I I Z0 /8 w ATTORNEY Patented Nov. 2, 1937 r V UNITED STATES PATENT OFFICE ROOFING Laney Snow, Noroton, Conn. Application June 26, 1934, Serial No. 732,396

2 Claims. (Cl. 108-9) The present invention relates to' roofing and place, acourse of undereave slate 20 is laid, being has particular reference to roofing construction retained in place by nails 22 passing through for slate roofs. suitable holes in the upper corners of the slate.

Fig. 1. Over the lower portion of the filler sheet 32 Referring now to'the drawing, It indicate th the second course of slate 34 is laid, the lower wood roof sheathing which may be of different d e o this course p rab y exte di a short forms of construction but which is shown as of distance below the lower e of S e 32 a the usual tongue-and-groove siding. Over the shown in the drawing. The course of slate 34 is 40 sheathing "1- there is laid the foundation conretained y nails 36 passing throu h t e filler sisting of sheets l2 of suitably impregnat d roofsheets 24 and 32 and also through the foundaing felt or the like.

As many courses of foundation fen; r employed course of slate 34, and the third course of slate as may be necessary to cover the area, t be 40, retained by nails 42, is laid over sheet 38 in a roofed. In the case of a. ridged roof the foundamanner sim r o h alre dy described wi h tion felt is preferably carried over the ridge on respect to S e 32 a Slate portion of sheet 32 and the upper portion of the 45 t each side to provide a double thickness for a Similarly the slate courses 44, 46 and 48, re- 50 distance of 6 inches or so on each siqe'of the tained by nails 50, 52 and 54, are laid over assoridge.

The several courses of slate are laid in overlapping relation so that a relatively narrow portion of each course is covered by the adjacent course. For example, if slate of -inch width is employed the slate is preferably laid so that 6 to 7 inches of each course is exposed in the finished roof. Thus, as will be evident from the drawing, each filler sheet underlies two full courses of slate and partially underlies a third course. Consequently, under the joints between courses, as for example at 62, there are 4 thicknesses of felt sheeting, at this point consisting of the sheets 56, 38, 32 and I2.

Furthermore, at the joints between adjacent slates "of the same course, as at 64, there is provided the protection afforded by 3 or 4 thicknesses of felt.

As is well known, leakage tends to occur due to the beating of rain upwardly under the lower exposed edges of the different courses of slate, and such leakage is effectively prevented with the construction just described, not only because of the sealing action of the lower edges of the several filler sheets which are in effect clamped between adjacent courses of slate, but also because of the fact that the lower portion of each filler sheet covers and effectively seals the holes in the underlying course of slate through which the nails pass.

it enables the roof to be laid with the minimum of labor.

Obviously the degree of skill required to lay the roof properly is not great, and in addition to the cost advantage due to the saving in the amount of slate required to roof a given area, the saving in labor as compared with ordinary construction The brittle characteristic of natural slate is such that chipping and the like inevitably is very substantial, and is in fact comparable to the labor charge incident to the laying of prefabri- The advantages to bederived from the use of the invention are greatest when it is made use of with natural slate, but it is to be understood that the invention is capable of application with other materials such as ceramics or synthetic compositions and as to which the term slate as used herein may be considered as applying.

It will further be understood that the term roofing felt as employed herein is used in a descriptive and not limiting sense.

What I claim is:

1. A roof the major portion of which is covered by slate of a single thickness underlaid by a dual thickness of roll roofing felt, said roll roofing felt being laid in smooth strips with individual slate shingles independently applied thereupon in a manner to form a course, said slate shingles being disposed in slightly overlapping staggered relation to the slate shingles of an adjacent course, and each strip of roll roofing felt having its lower portion substantially co-extensive with the bottom line of the course of slate shingles and its upper portion above the upper line of the next superposed course of slate shingles.

2. Roof construction comprising alternate layers of roll roofing felt and slate, the roll roofing felt being laid in smooth strips and the slate being independently laid in courses of individual pieces upon said strips and the pieces of slate of one course being staggered relative to the pieces of slate of the adjacent course and slightly overlapping the same, the arrangement of roll roofing felt and slate providing a roofwhich has slate of a single thickness over its major portion underlaid with a double thickness of roll roofing felt, the lower portion of each strip of roll roofing felt being substantially coextensive with the lower extremities of the individual pieces of slate forming the course, and the upper portion of said strip of roll roofing felt extending above the upper extremities of the slate forming the next course
