AOS Superior Roofing provides durable and cost‑effective built‑up roofing systems ideal for flat and low‑slope structures. BUR is constructed using multiple layers of reinforced fabric sheets bonded together with asphalt, creating a strong, watertight membrane. The surface is then topped with protective aggregate — such as gravel or stone — to enhance durability and shield the roof from weathering and impact.
Built‑up roofing is known for its long service life, often lasting up to 40 years with proper maintenance. Modern BUR systems may also incorporate insulation layers to improve energy efficiency and overall performance. The result is a continuous, sealed surface that delivers dependable protection and long‑term value for low‑pitch roofs.
