The bent edge (2051) of the edge flange comprises a compacted section (2053) closest to the bend line and a lip section (2054) extending from the compacted section at an angle (A) to the flange plane, and the pocket height (PH) is larger than the edge flange height (EH) at the compacted section and smaller than the maximum edge flange height (EHL) at the lip section. A method for mounting cover members of a cover assembly is also disclosed.

         7 . The cover assembly according to  claim 1 , where the first cover member further comprises an engagement section extending ways from the pocket opening along the pocket plane in a direction away from the pocket end. 
     
     
         8 . The cover assembly according to  claim 1 , where at least the edge flange is made from a sheet material. 
     
     
         9 . The cover assembly according to  claim 1 , where at least a portion of at least one of the first cover member and the second cover member is a folded sheet material. 
     
     
         10 . A method for mounting cover members of a cover assembly at one or more roof penetrating structures structure, comprising:
 Providing a first cover member comprising a pocket section forming a pocket having a pocket opening and a pocket end opposite the pocket opening, where a pocket depth is measured from the pocket opening to the pocket end, and where a pocket height is measured perpendicular to the pocket depth,   Providing a second cover member comprising an edge flange extending in an edge flange plane and having a bent edge bent along a bend line, said bend line forming a free edge of the edge flange, where an edge flange height is measured perpendicular to the edge flange plane, and where an edge flange width is measured in parallel to the edge flange plane, perpendicular to and away from the bend line, said edge flange width being equal to or larger than the pocket depth,   Arranging each of the first cover member and the second cover member with an interior side facing a roof window or a roof structure and an exterior side facing towards an exterior, and   Inserting the edge flange of the second cover member in the pocket of the first cover member by relative displacement of first cover member and the second cover member along an insertion direction extending in parallel with the edge flange plane, where a compacted section of a bent edge of the edge flange constitutes the leading edge of the edge flange during insertion into the pocket, and where a lip section extending from the compacted section at an angle to the edge flange plane presses against an inner surface of the pocket during the insertion and in the mounted state of the cover assembly.   
     
     
         11 . The method according to  claim 10 , comprising the following sequence of steps:
 Arranging the cover assembly in a narrow configuration by inserting the edge flange fully into the pocket,   Arranging the cover assembly at a roof penetrating structure, and   Bringing the cover assembly into an expanded configuration by retracting the edge flange partially from the pocket.   
     
     
         12 . The method according to  claim 11 , where the retracting is continued until both cover members are in contact with a roof penetrating structure, or until the bent edge on the second cover member engages with a bent edge on the first cover member.
