Abstract

A roof batten forming sheet for a roofing system for a building, the building including a plurality of spaced apart rafters, the roof batten forming sheet including a base panel section which includes opposed side edge portions, at least one of the side edge portions being configured so as to at least in part form a roof batten for retaining roofing thereon.

1 . A roof batten forming sheet for a roofing system for a building, the building including a plurality of spaced apart rafters, the roof batten forming sheet including a base panel section which includes opposed side edge portions, at least one of the side edge portions being configured so as to at least in part form a roof batten for retaining roofing thereon.  
   
   
       2 . A roof batten forming sheet according to  claim 1  wherein said base panel section has an upper face and at least one side edge portion is a generally L-shaped section one leg extending laterally away from the upper face of base panel section and the other leg being spaced from and generally parallel to the base panel section.  
   
   
       3 . A roof batten forming sheet according to  claim 2  wherein each of said opposite side edge portions include a said L-shaped section.  
   
   
       4 . A roof batten forming sheet according to  claim 1  wherein said at least one side edge portion is a generally U-shaped section.  
   
   
       5 . A roof batten forming sheet according to  claim 1  further including reinforcing ribs in said base panel section.  
   
   
       6 . A roof batten forming sheet according to  claim 5  wherein said base panel section is generally rectangular when viewed in plan and having further opposed side edge sections extending between said opposed side edge sections, said reinforcing ribs extending between said further side edge sections.  
   
   
       7 . A roofing system for a building, the building including a plurality of spaced apart rafters support on a building frame the roofing system including a plurality of roof batten forming sheets according to  claim 1  said sheets, in situ being disposed on said rafters, at least one said sheet spanning between adjacent rafters, adjacent said sheets being adapted to be assembled together so that the adjacent side edge portions thereof form a roof batten for retaining roofing material thereon.  
   
   
       8 . A roofing system according to  claim 7  wherein said base panel section has an upper face and at least one side edge portion is a generally L-shaped section one leg extending laterally away from the upper face of base panel section and the other leg being spaced from and generally parallel to the base panel section.  
   
   
       9 . A roofing system according to  claim 8  wherein each of said opposite side edge portions include a said L-shaped section.  
   
   
       10 . A roofing system according to  claim 7  wherein said at least one side edge portion is a generally U-shaped section.  
   
   
       11 . A roofing system according to  claim 7  further including reinforcing ribs in said base panel section.  
   
   
       12 . A roofing system according to  claim 11  wherein said base panel section is generally rectangular when viewed in plan and having further opposed side edge sections extending between said opposed side edge sections, said reinforcing ribs extending between said further side edge sections.  
   
   
       13 . A roofing system according to  claim 7  further including a starter batten strip which is adapted to be mounted to the rafters and a side edge portion of a first of said roof batten sheet is adapted to be fitted thereto.  
   
   
       14 . A roofing system according to  claim 8  wherein said starter batten includes a substantially U-shaped section having a base and two legs, said base, in situ, being secured to adjacent rafters, one of said legs forming part of a batten when connected to a roof batten forming sheet, the other of said legs providing means for mounting thereto a fascia.  
   
   
       15 . A roofing system according to  claim 8  wherein said starter batten is integral with one said sheets and includes a channel section and a batten forming section, the channel section, in situ, being disposed on an outer side of the batten forming section and includes an outer wall for mounting a fascia thereto.
