Flat roofs are a modern and practical roofing solution, especially for commercial buildings and contemporary homes. They are characterized by a nearly level surface, typically with a slight pitch to allow for water drainage. Flat roofs can be covered with a variety of materials, including modified bitumen, EPDM rubber, TPO, and PVC. These materials provide a waterproof membrane that protects the underlying structure. Flat roofs are cost-effective, provide additional usable space (such as for HVAC units or rooftop gardens), and are easier to inspect and maintain than pitched roofs.
