In the drawing,

Fig. 1 is a vertical section view on line l-l, Fig. 2;

Fig. 2 an elevation of a fragment of the improved roof;

Fig. 3 is a section on line 33, Fig. 2;

Fig. 4 is a fragmentary plan, with the elements ll removed;

Fig]. 5 is an isometric view of the elements It and l Fig. 6 is a section of a modification of the roof on said line 3-3; and

Fig. '7 is a side elevation of one of the elements 5 on a larger scale.

At l are the roof rafters shown by Figs. I to 5) 2 is the roof sheathing secured on the rafters. Paralleling the rafters and in the present case coinciding therewith and suitably secured on the sheathing are the strips 3 and 4 of which the strips 3 may be ordinary furring strips and the strips 4, otherwise termed beams, may be somewhat narrower and each of considerably greater vertical dimension than the strips 3 as shown in Fig. 3.

My invention contemplates the use, in the portion of the roof cover which is to occupy the major part of the roof area, of elements coming already formed in a standard size and rectangular shape and as fiat usually stiff sheets and composed of any material suitable for use as roof covering,'as asbestos or other composition material. These elements, which I term the main or covering elements, are indicated at 5 and they will usually have such appreciable horizontal or long dimension as nearlyto span the distance between a roof rafter and the next but one or more rafters and a somewhat shorter transverse dimension; for instance, when the rafters are two feet apart on centers, the dimensions of each such element may be approximately S'Hl" x 2. They are to be laid in side by side series so that in each series each element shall overlap somewhat the one next below.

and (in the form In the preferred form each element is shaped to imitate lengthwise panels of equal width and in parallel planes inclined to the normal or original plane of the sheet forming such element, as by bending the material lengthwise at intervals 5 to form the rises 6 and leave the mentioned panels 1. As to that panel of each element which after such bending has its free margin in said normal plane the edge thereof is bent up, as at 8, whereas as to that panel which is left with its free margin elevated out of said plane the edge thereof is bent downwardly and returned, as at 9, the bends at 8 and 9 being substantially right-angular.

The adjoining side edges of any two adjoining series of the elements 5 must be supported and held down and means provided for shedding any water which might find its way between them. Hence I provide for each such edge an underneath telescoped series of supporting and watershedding gutter elements Ill and a superimposed telescoped series of water-shedding and retaining elements ll. These may be formed of the same material as the elements 5 and molded, pressed or otherwise formed to shape.

Each element I0 is trough-shaped and has its side walls converging from one end to the other of the element, and one suchwall Illa preferably higher than the other, these elements being constructed in this respect as rights and lefts. The

narrower end of each such element is to be received in the wider end of its neighbor so that when the series is arranged at an incline with the wider ends of the elements up an effective water shedding gutter will be produced.

Each element II is likewise trough-shaped, being adapted to be arranged, however, in inverted position and its side walls also converge from one end to the other; each of its side walls, as Ila, is stepped to match and snugly fit the 40 stepped form of the elements 5, and. its top wall l lb is preferably pitched in both directions from the center plane. The narrower'end of each such element is to be received in the wider end of its neighbor so that when the series is arranged at an incline with the narrower ends of the elements up an effective water-shedding shield is formed.

In laying the roof cover the work is done up the pitch of the roof. First the gutter elements I I! (one right and the other left) are attached to the opposite sides of the strips or beams 4, as by nailing them thereto at l2, Fig. 3, preferably until two complete gutters are left flanking each such strip. Then the elements 5 are laid on and nailed at their upper edges, as at l3, to the furring strips 3, one after another up the pitch, their side edges resting on the lower side walls of the elements IQ and the returned lower edge of each in any series overlapping the upper edge of the one below. Finally, the elements H are laid on and nailed at their upper edges, as at M, to the strip 4, one after another up the pitch, the stepping of their side walls being made exactly to fit or mesh with that of the elements 5 and the lower edge of each overlapping the one below.

In Fig. 6 the elements 5, l0 and H are the same as in Figs. 1 to 5. But since in this case the roof frame is without sheathing and furring strips I provide on the alternate rafters superposed strips or beams i5 and strips I5 flanking them and below the top surface of the rafters, the elements ill resting on the strips t6 and the elements l I straddling and resting on the strips l5; both sets of elements 50 and II are nailed to these strips 15.

At the peak of the roof an element I1, substantially of the same form as each element H, may straddle the joint between each two oppositely pitched series of elements 5 and be nailed to the ridgepiece 58, the same being in length equal to the width of the elements 5 and itself straddled by lateral inverted trough-shaped extensions lsa of cap elements l9 each comprising two inverted trough-shaped elements formed as a unit and reversely pitched. And the lowest element in each series of elements I! may have some form such as that shown at Ha: which will make it ornamental and afford protection against the weather.

Since the depending flanges or side walls of the shield formed by the elements I! bear upon the elements 5 they act as hold-downs therefor and when their edges are stepped to conform and mesh with the stepping of the covering formed by the elements 5 the shield not only coacts with the nailing at E3 to support the elements 5 but to exclude snow, sleet and, to a considerable extent, rain-water. The parts Hi, H and 4 (or III, H and I5) form housings into which the side edges of the coverings project (to wit, through the slots formed between the edges of the elements IE) and H) and any water which may enter these housings will drip from said edges of the coverings into the gutters formed by elements it and drain oif to the main gutter as shown at 3:. It will be noted that each housing forms a void around the received edgeportion of each covering; in other words, that there is no broad surface-to-surface contact between the received part of the covering and the interior of the housing. This discourages the travel of admitted moisture by capillary attraction and encourages the drying of such moisture.

The bends in the elements 5 between their panels and at their upper and lower edges reinforce said elements against the weight of the roofer and besides insure against their warping; the bend at the lower edge is a rebend so as to afford a surface-to-surface rather than an edgeto-surface contact with the next underlapping element, thus reinforcing said edge against angular displacement under the weight of the roofer. Where each two adjoining elements 5 lap a void 28 is desirably left between the bend 8 of one and that 9 of the other again to discourage the travel upward of moisture by capillary attraction.

For the material of the elements 5, I0 and H there may in some cases be used sheet metal having a composition on one or both sides.

Having thus fully described my invention what I claim is:
