Abstract

Plastic molded roofing tile arranged so that laterally positioned tiles overlap in a ridge and channel arrangement. An upstanding flange at the top end of this overlap dams water flow against movement in that direction. Longitudinally related tiles are also overlapped with an upstanding flange at the upper end of the lower tile engaging in a transverse groove through reinforcing ribs in the bottom of the upper tile. Upstanding nailing bosses in the lower tile engage between the flanges to provide a locator stop to locate and rigidize the interrelationship. In one embodiment, the upstanding flange lockingly engages the downwardly directed ribs to prevent direct upward lifting of the upper tile.

Claims

1. A roofing tile adapted to be molded from a material including synthetic polymer composition material and comprising:

a planar top panel having a downturned flange at the bottom thereof, said planar top panel and said downturned flange being adapted to be substantially exposed to the weather;

an upturned flange at the top end of said top panel;

lateral edges on said top panel, said lateral edges being directed lengthwise of said roofing tile from one flanged end to the other flanged end, said lateral edges being adapted to laterally overlap and interlock with laterally adjacent identical tile;

at least one nailing boss on said roofing tile, said nailing boss being positioned adjacent said upturned flange, and extending upwardly from said top panel; and

at least one longitudinal rib formed beneath said top panel, a notch in said longitudinal rib adjacent said downturned flange, said notch in said longitudinal rib being positioned to engage said upturned flange of a longitudinally overlapping identical tile, said nailing boss extending upward to engage beside the rib to provide a lateral stop between adjacent rows of assembled tiles whereby individual tiles of the next adjacent row are accurately positioned against previously assembled tiles of the subjacent row.

2. The roofing tile of claim 1 wherein said roofing tile has two nailing bosses adjacent said upturned flange, each of said nailing bosses extending upwardly from said top panel, at least as far as said upturned flange so that either one of said nailing bosses can act as a stop against the longitudinal rib beneath a longitudinally adjacent overlapping tile.

3. The roofing tile of claim 2 wherein there are two downwardly extending ribs beneath said top panel, said downwardly extending ribs being spaced from each other to strengthen said top panel, each of said ribs having a said notch therein, and each of said ribs being shaped along the edge away from said top panel in such a manner as to engage a roof deck on one side of said notch and the adjacent tile which it is overlapping on the other side of said notch, said notches in said ribs thus positionally defining adjacent overlapped roofing tile.

4. The roofing tile of claim 1 wherein said upturned flange and said notch in said reinforcing rib are obtusely, angularly related with respect to said top surface of said roofing tile so that, when adjacent longitudinal tiles are overlapped and said flange is engaged in said notch, the upper tile is restrained from direct upward motion by interengagement with the adjacent tile.

5. The roofing tile of claim 4 wherein said roofing tile has two nailing bosses adjacent said upturned flange, each of said nailing bosses extending upwardly from said top panel, at least as far as said upturned flange so that either one of said Nailing bosses can act as a stop against the longitudinal rib beneath a longitudinally adjacent overlapping tile.

6. The roofing tile of claim 5 wherein there are two downwardly extending ribs beneath said top panel, said downwardly extending ribs being spaced from each other to strengthen said top panel, each of said ribs having a said notch therein, and each of said ribs being shaped along the edge away from said top panel in such a manner as to engage a roof deck on one side of said notch and the adjacent tile which it is overlapping on the other side of said notch, said notches in said ribs thus positionally defining adjacent overlapped roofing tile.
