         10 . The roof window according to  claim 9 , where the head flange abuts the distal edge. 
     
     
         11 . The roof window according to  claim 1 , where the diverter rail comprises a diverter flange between the proximal edge and the distal edge, said diverter flange projecting away from the top frame member. 
     
     
         12 . The roof window according to  claim 1 , where the diverter rail is attached to the top flashing member or the top sash covering. 
     
     
         13 . The roof window according to  claim 1 , where the proximal edge of the diverter rail is inserted into a groove in the top frame member or in an interface unit attached thereto. 
     
     
         14 . The roof window according to  claim 1 , where the diverter angle is adjustable. 
     
     
         15 . The roof window according to  claim 1 , where the diverter rail is replaceable. 
     
     
         16 . The roof window according to  claim 1 , where the diverter rail is attached to a flange of the top flashing member. 
     
     
         17 . The roof window according to  claim 16 , where the diverter rail includes a bent edge in which the flange of the top flashing member is inserted.
