A roof mesh installation apparatus for a mining machine includes a mesh roll carried at a dispenser at a forward position of the machine capable of unrolling mesh to be laid and bolted at a tunnel roof. A tensioning device positioned at the dispenser is capable of actuation so as to apply a pre-tension to a forward and unbolted section of mesh with the tension being applied against an already laid and rearward bolted mesh section. Accordingly, an automated roof mesh installation apparatus and method is provided.
