There is no simple answer to the question of whether flat roofs or regular roofs are better. It depends on a number of factors, including the climate, the type of building, and the budget. In general, however, flat roofs have several advantages over regular roofs. Flat roofs are less expensive to build than regular roofs, and they are also easier to maintain. Flat roofs are also better suited to warmer climates, as they tend to retain heat better than regular roofs.
