Built-Up Roofing

We often recommend built-up roofing (BUR) systems for industrial roofing due to their simplicity, cost effectiveness and durability. Our techs install BUR systems with hot mopping or cold application techniques depending on the unique needs of your building, then finish with gravel or a smooth coating to guard against water infiltration. Top benefits include:

  • 15- to 30-year lifespan
  • Rugged design
  • Withstands regular foot traffic, allowing installation of rooftop HVAC units and other equipment
  • Guards against leaks and moisture
  • UV protection
  • Flame resistant
  • Seamless design with little need for maintenance

Modified Built-Up Roofing

What sets modified built-up roofing apart from a standard BUR system? It all comes down to polymers that provide additional defenses against wear and the elements. When combined with asphalt, these polymers form bitumen, a tough material that is rolled on in sheets. Modified built-up roofs are not recommended for areas that require extensive foot traffic, but provide an excellent seal and long lifespan. Benefits include:

  • Up to 20-year lifespan
  • Extreme resistance to tears, punctures and similar damage
  • Waterproof and flame resistant
  • Environmentally friendly
  • Energy efficient
  • Easy to maintain and repair


Thanks to its long history of quality performance, single-ply roofing remains a popular choice for many industrial projects. Your existing roof will be cleaned or removed before installing a new single-play roof, and you’ll have the choice of several materials and attachment options to suit your needs. This extremely flexible option is ideal for large areas and provides many benefits, such as:

  • Insulating properties that help control heating and cooling costs
  • Chemical and acid rain resistance
  • UV resistance
  • Lightweight
  • Able to withstand harsh weather
  • Low maintenance
  • Creates a smooth runoff for rain water and snow melt
