Abstract: A self-propelled apparatus for dislodging and collecting materials from a surface and having particular use in removing roofing from a roof deck. The apparatus includes a small tractor-like vehicle having a frame and a blade extends forwardly of the frame and is adapted to move along the surface. A brush is mounted adjacent the forward edge of the blade and is adapted to sweep the dislodged material up the blade to an endless conveyor which is mounted on the frame. The brush includes a series of rigid fingers which are located within the bristles and act to move heavy materials up the inclined blade to the conveyor.
