Built-Up Roofing (BUR)
BUR Roofing, also known as Built-Up Roofing, is a traditional multi-ply flat roof system that has been used for over a century. It consists of alternating layers of reinforcing felts or mats and bitumen (asphalt or coal tar), creating a thick, durable waterproof membrane.
BUR systems are known for their excellent waterproofing performance and longevity. The multiple layers provide redundancy, making them highly resistant to leaks. When topped with gravel or a mineral surface, BUR roofs also offer good protection against UV rays, fire, and physical damage. This roofing system remains a reliable choice for commercial, industrial, and institutional buildings with flat or low-slope roofs.
In Florida, BUR roofing continues to be used on many commercial properties due to its proven durability and ability to handle heat and occasional ponding water when properly designed and installed.
