A two piece retractable hard-top roof for interfacing with an automobile body assembly, the retractable hard-top roof having a forward roof component and a rearward roof component, wherein an 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. A front end of the forward roof component is selectively affixable to the windshield trim. The rearward roof component includes a rear window, is affixed at its rear end to the actuation mechanism, and is selectively conjoined at its front end to the rear end of the forward roof component to provide a single, rigid unit. In a retraction operation, the conjoined roof retracts to a first selected location, whereupon the forward roof component is detached from the rearward roof component and theafter seated 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 selectively covers a selected portion of the stowage compartment.
