What types of materials are commonly used for flat roofs?

Flat roofs are commonly made from materials like bitumen (BUR), EPDM rubber, TPO, PVC, and fiberglass. Fiberglass (GRP) is a popular choice due to its strength, flexibility, and long lifespan. It involves applying layers of fiberglass matting and resin to form a durable, watertight surface. Fiberglass is resistant to UV damage, cracking, and shrinking, offering a low-maintenance and long-lasting solution that can last 20 to 30 years or more with proper care.
