A covering system for roofs and for the outside of building walls is provided in which, on top, a high range of various decorative materials and elements ( 14, 15 ) can be fixed without penetrating the watertight layer. The system contains protruding elements ( 20 ) connected to the support ( 1 ) and flexible watertight membranes ( 4 ) arranged so as to cover and contact essentially the complete support surface, including the protruding elements. Panels ( 6 ), preferably rigid insulation panels with excellent resistance to water, are arranged so as to hold down the watertight membranes ( 4 ) onto the support ( 1 ), thus protecting the membrane from thermal cycling, UV rays and physical damage. The panels can be fixed with non-penetrating fastening means ( 16 ) to secure the complete system to the protruding elements ( 20 ) and to the support ( 1 ).
