Built-Up Roofing (BUR) projects encompass various roofing applications, including hot, cold, and ballasted methods. In hot BUR applications, layers of bitumen and reinforcing fabrics are heated and fused to create a durable membrane. Cold BUR involves using adhesives or asphalt emulsions, offering a more environmentally friendly alternative. Ballasted BUR systems incorporate a ballast layer like gravel to secure the roofing materials. These applications provide:

  • Robust, multi-layered protection.

  • Making BUR a popular choice for flat or low-sloped roofs.

  • Ensuring resilience against weather elements and extending the lifespan of the roofing system.
