Roofing for buildings, with synthetic resin molded components

Abstract

A tile made of stiff molded synthetic resin having edges which overlap when a plurality of tiles are assembled upon a roof and an upper continuous contoured ridge along the upper edge and a lower continuous contoured ridge along the lower edge. The upper and lower ridges being stepped shape to engage with horizontal continuity when a plurality of tiles are assembled upon a roof. A through hole is provided in the lower ridge which aligns with a slot in the upper ridge to allow a screw to pass therethrough fastening two contiguous rows of tiles to a supporting structure.

1 . A roofing for buildings, the roofing comprising: 
 a plurality of tiles each having a first and second side and having an upstream edge and downstream edge, said each tile also having first and second side edges;    an upstream ridge extending from said first side along said upstream edge of said each tile;    a downstream ridge extending from said second side along said downstream edge of said each tile, wherein each said downstream ridge is step shaped to engage with said upstream ridge of another said tile;    contours contained in a first and a second side edges of said each tile which are complimentary in a partial overlap of said first and second side edges of adjacent said tiles, said contours forming seals that carry off water;    said downstream ridge of said each tile defining a hole through a respective said tile;    said upstream ridge of said each tile defining a slot through a respective said tile;    a plurality of anchoring devices, each of said slots and said holes being arranged on said tiles to have each of said slots be receivable of one of said anchoring devices passed through a corresponding said hole in an adjacent said tile, said tiles being arranged on a supporting structure and each of said plurality of anchoring devices connecting two adjacent said tiles directly to said supporting structure.    
     
     
         2 . A roofing in accordance with  claim 1 , wherein: 
 each of said holes and said slots extend through a respective said tile from said first side to said second side;    said anchoring devices include screws with heads sealable against said tiles.    
     
     
         3 . A roofing in accordance with  claim 2 , wherein: 
 said screws are applicable by screwing and unscrewing repetitively, said screws include heads acting against the tiles as a seal against rain.    
     
     
         4 . Roofing according to  claim 1 , wherein the holes are formed next to said downstream edge in which the downstream ridge overlaps the upstream ridge of a said tile below, provided with said slots.  
     
     
         5 . Roofing according to  claim 1 , wherein the slots are formed in corresponding enlargements of the upstream ridges on the upstream edge.  
     
     
         6 . Roofing according to  claim 1 , wherein: 
 one of said contours ends downstream with a stepped recess to facilitate water carry-off.    
     
     
         7 . Roofing according to  claim 1 , wherein a plate of the tile forms a bent tile contour with an external and an internal arched terminal edges which engage, when laid, with those of the plates of contiguous rows.  
     
     
         8 . Roofing according to  claim 1 , wherein some said tiles are manufactured from a clear material.  
     
     
         9 . Roofing according to  claim 1 , wherein the tiles contain linear ridges on said second side at said downstream and upstream edge to rest on the supporting structure.  
     
     
         10 . Roofing according to  claim 1 , wherein said tiles are made of stiff, molded, synthetic resin.  
     
     
         11 . Roofing according to  claim 1 , wherein said tiles are manufactured from polycarbonate.  
     
     
         12 . Roofing for buildings including tiles and devices for anchoring said tiles to a supporting structure, said tiles including, along an upper and lower edge which, when laid, are substantially perpendicular to a maximum slope line, an upper continuous contoured ridge along the upper edge and a lower continuous contoured ridge along the lower edge, and along a first and a second edge which, when laid, are substantially parallel to the maximum slope line, labyrinth contours which are complementary in a partial overlap between said first and second edges of contiguous tiles to make labyrinth seals which will carry off rain water towards the tiles of the row below, said ridges being step-shaped to engage, when laid, with horizontal continuity, a row of said tiles below to the row of said tiles above, wherein anchoring devices include on the tiles a through hole along the lower ridge and a slot along the upper ridge to fasten two said tiles from contiguous rows that partially overlap along the ridges, to said supporting structure, said anchoring device being accessible and said first and second edges overlapping each other; 
 said anchoring devices include screws or nails that are accessible from above which pass through the through hole of the overlapping tile and the slot of the lower tile and which are fastened to the supporting structure, so that said anchoring device simultaneously connects the edge of the upper tile, the edge of the lower tile and the supporting structure, said anchoring means being accessible from above perpendicularly to the roofing.    
     
     
         13 . A roofing in accordance with  claim 12 , wherein: 
 said screws are applicable by screwing and unscrewing repetitively, said screws include heads acting against the tiles as a seal against rain.    
     
     
         14 . A roofing for buildings, the roofing comprising: 
 a plurality of tiles each having a first and second side and having an upstream edge and downstream edge, said each tile also having first and second side edges;    an upstream ridge extending from said first side along said upstream edge of said each tile;    a downstream ridge extending from said second side along said downstream edge of said each tile, wherein each said downstream ridge is step shaped to engage with said upstream ridge of another said tile;    contours contained in a first and a second side edges of said each tile which are complimentary in a partial overlap of said first and second side edges of adjacent said tiles, said contours forming seals that carry off water;    said downstream ridge of said each tile defining a hole through a respective said tile;    said upstream ridge of said each tile defining a slot through a respective said tile;    a plurality of anchoring devices, each of said slots and said holes being arranged on said tiles to have each of said slots be receivable of one of said anchoring devices passed through a corresponding said hole in an adjacent said tile,    said slots are elongated and have a size greater than said anchoring devices;    said holes are circular and approximately the same size as said anchoring devices.
