The present invention relates to a roll shutter for hinged casement type roof windows, which includes two guide rails (14) for the roll shutter bars (12), which guide rails (14) run parallel to each other and are connected to the shutter and is provided with a roll shutter activation device which includes a first and a second control cable (40 and 42) as well as a third control cable (50). The first and the second control cables (40 and 42) are led to a connection point (47) and are attached to each other. The connection point (47) is also connected with the third control cable (50) which is guided from a spool (26) on the winding shaft (24) of the roll shutter, through an activation loop (59) accessible to the user and an adjoining buffer loop (43) to the connection point (43). The length of the buffer loop (43) is at least as large as the displacement path of the roll shutter (10) between its completely open and completely closed positions.
