Claim:
A method of facing a roof structure, said method comprising: securing a facing to respective lower flanges of first and second spaced-apart purlins of the roof structure, said facing extending directly between the respective lower flanges of the first and second purlins, wherein said securing step comprises using a first adhesive zone to adhere the facing directly or indirectly to a bottom face of said lower flange of said first purlin and using a second adhesive zone to adhere the facing directly or indirectly to a bottom face of said lower flange of said second purlin; wherein said step of securing comprises: suspending a carriage beneath said first and second purlins such that a first base portion of said carriage is suspended beneath said first purlin and a second base portion of said carriage is suspended beneath said second purlin by placing a first foot that is connected to said first base portion in contact with an upper surface of said lower flange of said first purlin and by placing a second foot that is connected to said second base portion in contact with an upper surface of said lower flange of said second purlin, wherein said first and second base portions of said carriage are connected to each other by at least one cross-member that extends between and interconnects said first and second base portions; rotatably supporting a roll of said facing on said carriage beneath said first and second purlins with a first end of said roll located adjacent said lower flange of said first purlin from which said first base portion is suspended and an opposite second end of said roll located adjacent said lower flange of said second purlin from which said second base portion is suspended, said step of rotatably supporting said roll comprising rotatably supporting said first end of said roll relative to said first base portion of said carriage and rotatably supporting said opposite second end of said roll relative to said second base portion of said carriage such that said roll extends between said first and second base portions of said carriage; urging said facing into contact with said bottom faces of said lower purlin flanges; and, dispensing said facing from said roll by moving said first and second feet of said carriage on said upper surfaces of the purlin flanges such that said carriage moves relative to and beneath said first and second purlins and said first adhesive zone and said second adhesive zone adhere said facing dispensed from said roll to said first and second purlins from which said carriage is suspended.
