5 Claims.

This invention relates to an improved roofing or roof covering, and more particularly relates to a composite roofing built up from units into a finished roofing structure.

The invention contemplates a slate or tile roof having the shingle efiect.

The principal object of the invention is the provision of a composite roofing embodying improved features of construction rendering it durable, fireproof and weatherproof.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which Figure 1 is a fragmentary plan of a roof constructed in accordance with the invention and portion thereof being broken away to show underlying parts;

Figure 2 is an enlarged transverse section on the line 2-2 of Figure 1;

Figure 3 is an enlarged longitudinal section on the line 3-3 of Figure 1;

Figure 4 is a plan of one of the roofing units;

Figure 5 is a fragmentary perspective of the slate hanger.

The invention is well suited for application to a new roof or for re-covering an old roof, and in the drawing is shown applied to an inclined roof for which type the invention is primarily devised.

A roof or roofing structure will be constructed of the required number of similar units, one of which is shown in Figure 4 of the drawing. The unit consists of suitable material such as a sheet of felt 10 of the required size to have applied thereto slates or tiles 11, preferably three, which when laid in a row will partly cover the sheet 10 so as to provide a top marginal portion 12 and a side marginal portion 13. Use is made of a quick setting mastic consisting of a mixture of asphalt and asbestos fiber. The mastic designated 14 is spread on the sheet 10 to cover an area equal to that of the slates 11. Use is made of pieces of metal 15, preferably of copper. The pieces 15 are set in the layer of mastic 14, and are so spaced and disposed as to occur beneath the adjacent paralleling marginal portions of the slates 11. The slates 11 are set in the mastic 14,

0 and the latter forms a secure bond between the slates 11 and the sheet 10. The pieces of metal 15 provide an adequate weathering means at the contiguous side edges of the slates 11 and prevent the elements of weather from making inroads beneath the slates. In order to more securely hold each slate 11 in place against slipping there is provided means in the form of a hanger 16 connected with the upper end of the slate as at 17 and projecting upwardly therefrom. The hanger 16 has an eye or loop 18 to receive a suitable fastener such as a nail 19 driven into the sheet 10 and structure which supports the unit.

In accordance with the invention each unit of the character described above is laid on the boards or supporting structure 20 of the roof and is secured thereto by the fasteners 19 and additional fasteners if desired. The units are laid to present rows of slates, the lower ends of the slates of each row overlapping the upper ends of the slates of the next lower row as shown most clearly in Figure 2. It is to be understood that the side portions of the sheets 10 will be overlapped by reason of the projecting marginal portions 13. The slates 11 are beveled at the edges. The slates are arranged to give the effect of a shingle roof.

From the foregoing it will be apparent that there has been described a roofing structure which may be laid in a comparatively short time and which will be weatherproof, and particularly efficient to shed rain water; that by reason of the metal pieces 15 the elements of weather will be excluded from beneath the slates at the exposed joints; and that the slates will be securely held against slippage in case of the mastic 14 being softened in extremely hot weather.

I claim:

1. A roof structure including a sheet of suitable material, mastic on said sheet, slates set in the mastic contiguous each other, and metallic pieces set in the mastic beneath the adjacent paralleling marginal portions of said slates.

2. A roof structure including suitable material like felt, mastic on said material, slates set in the mastic and arranged in rows, the lower ends of slates of each row overlapping the upper ends of the slates of the next lower row, and metallic pieces set in the mastic beneath the adjacent side marginal portions of said slates.

3. A roof structure including a suitable base consisting of sheet material, slates arranged in rows, suitable material to form a bond between the base and slates, and metallic pieces set in the bonding material beneath the adjacent contiguous marginal portions of said slates. I

4. A roof structure including a layer of cementitious material, slates set in said material, and metallic pieces set in said material and disposed beneath the adjacent marginal portions of the slates. m

5. A roof structure including rows of slates, cementitious material, and metallic pieces set in said material and disposed beneath the adjacent marginal portions of the slates.
