Built-Up Roof Systems

Built-Up Roofing (BUR) is a traditional roofing system composed of multiple layers of bitumen and reinforcing fabrics, topped with a protective layer of gravel or mineral granules. BUR is known for its redundancy and robust performance in guarding against weather extremes. 

Key Features & Benefits 

• Multi-Layer Protection: 

• • Multiple layers create a redundant system that provides extra security against leaks. 

• Durability: 

• • Gravel topping protects the membrane from UV damage and mechanical wear. 

• Proven Reliability: 

• • A time-tested solution with decades of successful installations in commercial settings. 

• Versatile Application: 

• • Suitable for a wide range of roof slopes and building types. 

Comparison & Considerations 

• BUR vs. ModBit: BUR offers a traditional, multi-layered approach, while ModBit leverages modern polymers for enhanced flexibility and simpler installation. 

• Installation Techniques: 

• • Involves layering and embedding reinforcing materials, ideal for large-scale commercial roofs requiring extensive coverage.
