Abstract: A felt roller serves as a device for the application of felt paper in a pitched roof environment and which is capable of being maneuvered by use of the provided handle which is attached at each end of a center axle. The axle supports a roller pin assembly and a caster assembly. The caster assembly utilizes two caster wheels to gain multi-directional maneuverability. The caster wheels are restricted in their movement to allow left, right and up directions of movement when on a roof thus offering control and stability of the felt roller unit. The roller pin assembly provides free spinning rotation of the felt roll as needed for stationary dispensing as well as tack and roll applications. The axle includes on the upper end a support wheel which is removable so as to allow loading of a roll of felt material. The handle is pivotable on the axle and extends outwardly to allow the felt roller unit to be guided from above.
