Abstract
An apparatus which is useful on pitched roofs includes structural features which help keep roofing materials from sliding off the roof. The apparatus also protects roofers from heat and abrasion from the roof surface on which they are working. A substantially solid foam rubber wedge forms one component of the apparatus, and a substantially planar pad forms the other component of the apparatus. These components are placed in proximity to each other so that the roofer, when situated on the pad, can readily reach roofing materials disposed against the wedge. The wedge resiliently compresses when roofing materials are placed on its upper surface. This resilient compression, the angle of orientation of the wedge's upper surface, and the frictional engagement of the wedge with the roof surface each contribute in varying degrees to holding roofing materials in position on the roof. The pad is made of material which reduces the amount of heat passing from the roofing surface to the upper surface of the pad on which the roofer is situated.
