Built-Up Roofing (BUR) is a traditional roofing method preferred for low-slope or flat roofs. It consists of multiple layers of bitumen and reinforcing fabrics that create a finished membrane. Known for its durability, BUR has been a reliable choice in the roofing industry for over a century.

Benefits of Built-Up Roofing

BUR offers several advantages for commercial roofing applications:

  • Exceptional Durability: The multiple layers in BUR provide excellent durability and resistance to water, weather, and foot traffic.
  • High Performance: With its multi-layered approach, BUR effectively prevents water leakage and provides superior waterproofing capabilities.
  • Energy Efficiency: BUR systems can include reflective coatings that significantly reduce building cooling costs by reflecting solar heat.
  • Cost-Effectiveness: Despite its resilience and longevity, BUR is cost-effective compared to other modern roofing systems, especially when considering its lifespan.
  • Fire Resistance: The materials used in BUR are inherently fire-resistant, enhancing the safety of the building.

Components of BUR

The typical components of a Built-Up Roof include:

  • Base Sheets: Attached to the roof deck to serve as the foundation for layering.
  • Interply Layers: Multiple layers of bitumen are alternated with reinforcing fabrics like fiberglass or polyester, known as roofing felts.
  • Surfacing: The top layer may be a cap sheet or gravel embedded in hot asphalt to protect from UV rays and physical damage.

Installation Process

Our BUR installation process includes:

  1. Inspection and Preparation: Evaluating the existing roof condition and preparing the surface for optimal outcomes.
  2. Application of Layers: Precisely applying each layer to ensure tight sealing and bonding.
  3. Finishing: Applying the surfacing layer, which varies based on client needs and environmental factors.
  4. Quality Checks: Conducting thorough inspections post-installation to guarantee the integrity and performance of the roofing system.
