An actuation mechanism for a two piece retractable hard-top roof that interfaces with an automobile body assembly, the retractable hard-top roof having a forward roof component and a rearward roof component which are selectively conjoinable, wherein the actuation mechanism and its associated framework are not located in the passenger compartment, being generally located in a stowage compartment, and wherein a minimal fore-aft dimension is needed to accommodate storage of the retractable hard-top roof. The actuation mechanism is microprocessor controlled, and the rearward roof component is affixed at its rear end to the actuation mechanism. In a retraction operation, an affixment assembly detaches the forward roof component from the windshield trim, a rearward carriage retracts the conjoined roof to a first selected location, a joinder assembly detaches the forward roof component from the rearward roof component, and a forward carriage seats the forward roof component inside the stowage compartment whereat the forward roof component is juxtaposed the rearward roof component. A deployment operation is essentially a reverse of the aforesaid retraction operation. A tonneau cover assembly selectively covers a selected portion of the stowage compartment.
