A roof assembly (3) for a convertible motor vehicle (1) includes a roof frame (2) adapted to be part of a chassis of the motor vehicle (1), a removable roof portion (4) configured to be arranged in contact with the roof frame (2) in an attachment position, a lock device (5) carried by the roof portion (4) and configured to be operated when the roof portion (4) is in the attachment position according to a first operation mode, according to which the lock device (5) cooperates with the roof frame (2), thereby realizing a constraint to secure the roof portion (4) to the roof frame (2) in the attachment position, and according to a second operation mode, according to which the lock device (5) recedes from cooperating with the roof frame (2), thereby removing said constraint, characterized by further comprising a magnetic device configured to generate a magnetic field, the magnetic field being variable according to the operation of the lock device (5) when the roof portion (4) is in the attachment position, a magnetic field transducer (10) configured to detect the magnetic field at least when the roof portion (4) is in the attachment position and to output a signal according to the detected magnetic field, and a control unit (11) coupled to the transducer (10) and configured to extract from the signal a piece of information associated with the presence of the roof portion (4) in the attachment position and/or with the presence of said constraint.
