Definitions

• the present invention relates to a metal roofing accessory. Sheets are used to make a metal roof of a building. Subsequently, they will be referred to as "cover sheet”. To make a roof, several metal roofing sheets are assembled in partial overlap. The edges of such a roof are terminated by a rim strip.
• a edge strip is a covering accessory intended to provide protection against the elements, in particular against the infiltration of water, from the edge of a roof, at the level of the junction zone between the upper end of the wall and the roof.
• a strip of shore runs along the wall, under the roof line.
• the edge strips equip at least the edges of the roof where the latter is at the wall, without overflow.
• An edge strip may advantageously also equip a wall whose end is protected by an overhang of the roof, to enhance the protection against the weather.
• the presence of a strip of shore makes it possible to limit the entries of rodents by the roof.
