A device for reducing movements of a roof underlay (11) of a roof structure, the device comprising attachment means (31) for attaching the device to a batten (13) of the roof structure; a contacting element (32) for contacting the roof underlay (11); and an interconnecting element (33) interconnecting the attachment means (31) and the contacting element (32). The attachment means (31) comprises resilient members (31a, 31b) dimensioned to span the batten (13), and snapping ridges (31a', 31b') on the resilient members (31a, 31b) for interacting with edges of the batten (13) so as to allow the device to be attached to the batten by a snapping action of the resilient members (31a, 31b) and the snapping ridges (31a', 31b').
