A ventilated flexible dome for covering liquid manure storages. A cone-shaped dome (20) includes a circular base (30), a rigid ridge pole (23), support cables (26) connecting the base to the ridge pole, a cover (22), a flexible membrane arranged on the support cables (26) and a ventilation cone (42) with a rigid ridge pole. The circular base (30) includes a belt (62) that keeps the support cables (26) tight and stretches the cover (22). Space is left to allow the inflow of outside air under the cover (22). The rigid ridge pole (22) is supported by a central pole (27) inside or by other means of support outside the cover. An entrance hatch (46) may be added to facilitate access inside the dome. A flexible parabolic dome (120) is available for rectangular-shaped storages. The tension cables are replaced by a pair of roof hoops (124), in compression, whose feet are spaced apart and whose apexes converge.
