A 1,600 square foot roof is typically found on a single-story home with a rectangular or square floor plan. However, the exact size and shape of the roof will depend on the design of the house. For example, a 1,600 square foot ranch-style home with a simple gable roof may have a roof with an 1,800 square foot area. On the other hand, a two-story home with a more complex roof design may have a smaller roof with a 1,200 to 1,600 square foot area, but one that will cost more to replace due to the complexity of a roof design.
