A material transport system for delivering and dispensing a large capacity of materials at a construction site using a plurality of removable carriages, each bearing a roll of material, mounted on a movable frame. The frame comprises a pair of dual powered axles each driving either a set of drive flanged rollers, or a set of conveyors, for moving the system along purlins, or joists, of a building. The flanged rollers are used when dispensing of material to a side wall of the building is desired and the building is roofless, and when dispensing of material to an end wall of the building is desired and the building is roofed. The conveyors, which are removably mounted to the underside of the material transport system, are used for dispensing material to a side wall when the building is roofed, and when dispensing material to an end wall when the building is roofless. In either case, the flanged rollers, or the conveyors, are simultaneously driven by a common pair of dual-powered axles to negotiate the constant or changing elevation of a building's roof structure.
