Scaffolding system for roofs

A scaffolding system (1) comprising, in combination:

• at least one roof scaffold (4) including elongated parts (9) positionable in a first direction along a slope of a roof (2) of a building (3), the roof having a surface, the at least one roof scaffold including crosswise members (10) positionable in a second direction transverse to the first direction, the crosswise members adapted intended to be connected to the elongated parts (9), the roof scaffold (4) having at least one supporting structure (5), the supporting structure including supporting members, the supporting members including at least one first set of supporting members (11), at least one second set of supporting members (12) and at least one third set of supporting members (13), at least one conveying device (6) for moving material(27), up to the roof (2) and down from the roof on at least one inclined plane (20), the conveying device being connected to a recipient surface chosen from the class of recipient surfaces including a roof and a roof scaffold, the conveying device positionable with the supporting structure (5) at a distance from the surface of the roof thereby forming a space between the roof scaffold (4) and the surface of the roof (2) allowing the material to be moved into the space
