A flashing arrangement for a window with a mainly rectangular window frame comprising frame members consisting of a top frame member, two side frame members, and a bottom frame member is provided herein. The flashing arrangement includes flashing elements which are configured to be attached to the frame members, the flashing elements being profiles of a flexible material for providing a waterproof flashing frame around the window frame when mounted thereon, the flashing elements also matching the top frame member. The side frame members of the window have a U-shaped cross section. The flashing elements include a bottom plane which, in its working position is substantially-parallel to a glass section of the window. The flashing element also includes two upwardly-protruding side flanges. In such side flanges a first side flange is configured to be attached to an outside of a corresponding frame member of said window frame, and a second side flange is configured to serve as a seal in sealing abutment with an underside of surrounding roofing. Flashing elements matching the top frame member and the side frame members of said window frame are made of an elastically-deformable material. The flashing element matches the bottom frame member, and includes a profile having a mainly L-shaped cross section with an upright flange for connection to an outside of said bottom frame member, and an outwardly-protruding flange.The flashing frame can be manufactured by welding together extruded profile elements which are made of rubber or of a thermoplastic elastomer, or can be manufactured in one piece by injection moulding.
