A roof fiber-cement snow retainer has working, support and reinforcement surfaces. Working, support and reinforcement surfaces of the snow retainer are arranged as cramp-like roof element with angle of working element joining roof surface 90° and with angle of inclination of reinforcement surface with respect to working one within 30° and 60°, with determination with direct proportionality of dependence of acute angle of inclination on slope of roof construction. Structural angle transition pieces of support surface to working one, of working surface to reinforcement one and of reinforcement to support one are arranged with roundings. |
