When deciding between a new construction roof and a reroof, the key difference is the deck. New builds mean installing a roof from scratch on a bare deck, which is straightforward. Reroofing, however, involves tearing off old layers first—this can reveal hidden damage like rot or mold. That extra step adds labor time but can save your structure in the long run.
