Abstract: Equipment support systems and modular platforms provide an equipment support portion with lateral walkways and work areas. The platforms have a skeletal frame that supports a plurality of grates to form the work area. The frame of the platforms also has a number of support legs with circular bases at their lower ends to rest upon the roof or other support surface. The circular bases distribute the load of the supported equipment evenly upon the roof so that specific spots are not overloaded. Outriggers may be removably added to the platform to increase the dimensions of the platform thereby making the platform and supported equipment less prone to overturning from wind loading. Methods are described for providing a support platform designed to resist a specific design wind load. In some preferred embodiments, one or more of the support legs of the platforms are adjustable in length, to allow portions of the platform to be adjusted for differential settlement of the roof.

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.
