A flat roof is a type of roofing system that is nearly level, with a slight slope for water drainage. Unlike traditional pitched roofs, flat roofs are often used in commercial buildings and modern residential designs. They can be constructed using materials like asphalt, rubber, or membrane systems to provide waterproofing and durability. Flat roofs offer several advantages, including additional usable space for rooftop gardens or solar panels. However, they require regular maintenance to prevent water pooling and leaks. Proper drainage systems are essential to ensure the longevity and effectiveness of flat roofs in various weather conditions.
