News & Advice

The best roofing for commercial buildings depends on the specific needs but often includes built-up roofing (BUR), metal roofing, and thermoplastic polyolefin (TPO) roofing due to its durability and energy efficiency.

The commercial roofing differences are…

Built-Up Roofing (BUR)

• BUR consists of multiple layers of bitumen (asphalt or coal tar) alternated with layers of reinforcing fabrics such as fiberglass or polyester.
  • Advantages
    • Excellent waterproofing properties.
    • Long lifespan, especially when properly maintained.
    • Resistant to weathering, UV radiation, and foot traffic.
    • Provides good insulation properties.
  • Considerations
    • Can be heavy, requiring adequate structural support.
    • Installation may involve odors and fumes from hot-applied bitumen.

Metal Roofing

• Metal roofing can be made from various materials such as steel, aluminum, copper, or zinc.
  • Advantages
    • Long lifespan, often lasting 40 years or more.
    • Lightweight yet durable, resistant to fire, rot, and insect damage.
    • Reflective surfaces can help reduce cooling costs in warm climates.
    • Low maintenance requirements.
  • Considerations
    • The initial cost may be higher compared to some other roofing options.
    • Expansion and contraction with temperature changes may cause noise in some cases.

Thermoplastic Polyolefin (TPO) Roofing

•  TPO roofing is made of a single-ply membrane typically composed of a blend of polypropylene and ethylene-propylene rubber.
• • Advantages
    • Energy-efficient and reflective, helping to reduce cooling costs.
    • Lightweight and flexible, making installation easier and less labor-intensive.
    • Resistant to UV radiation, ozone, and chemical exposure.
    • Seam welding creates strong, watertight seals.
  • Considerations
    • May not be as durable as some other roofing materials, with a lifespan typically around 15-30 years.
    • Susceptible to punctures from sharp objects.
