Popular Types of Commercial Roofs Explained

Built-Up Roofing (BUR): The Time-Tested Solution

Built-Up Roofing, commonly known as BUR, has been a staple in the commercial roofing industry for over a century. This roofing system consists of alternating layers of bitumen and reinforcing fabric, creating a tough, long-lasting roof surface.

Pros:

  • Excellent waterproofing
  • Fire-resistant
  • Low-maintenance

Cons:

  • Heavy
  • Strong odors during installation
  • Potential for leaks if not installed correctly

EPDM Roofing: The Rubber Revolution

Ethylene Propylene Diene Monomer (EPDM) roofing is a single-ply membrane system made from synthetic rubber. Its popularity has soared in recent years due to its durability and ease of installation.

Pros:

  • Lightweight and flexible
  • Resistant to UV radiation and ozone
  • Long lifespan (up to 30 years)
