Flat roofs are a type of roofing system that is nearly level, with a slight slope for drainage. They are commonly found in commercial buildings but can also be used in residential structures. Flat roofs are typically constructed using materials like asphalt, rubber, or membrane systems to provide waterproofing and durability. One of the main advantages of flat roofs is their usability; they can serve as additional outdoor space for gardens, patios, or solar panels. However, they require regular maintenance to prevent water pooling and leaks, making proper drainage systems essential for longevity.
