Built-Up Systems

A built-up/gravel roof can weigh from 2 to 5 pounds per square foot. Thicker systems consisting of several bitumen and roofing felt layers will weigh more than thinner roofs built with fewer layers. Due to the high weight of Built-up or Gravel roof systems, when heavy rain and snow occur the additional weight puts increased strain on your commercial or industrial building.

Although Gravel Roofs have great durability, this added feature causes Built-Up roof systems to weigh much more than Mod-Bit and other modern roof systems, which can present challenges to many buildings. Gravel/Built-Up roofs also tend to accumulate dirt and other debris. Because of this, it can be difficult to locate the point of water entry in leaking Built-Up/Gravel roofs. Additionally, in the event of hail damage, these systems disguise any damage that occurred. Displaced gravel and trapped debris can also block drain and gutter systems, which is another reason why a BUR roof may not be the optimal choice for your commercial or industrial roof.

Built-up roofs do require regular maintenance to get the most life out of them. This ongoing process requires regular inspection of the roof, cleaning debris, ensuring drainage systems are clear, replacing displaced gravel, and maintaining records of all maintenance performed.

Yes, Built-Up/Gravel roofs provide traction and weight distribution for foot traffic. However, if heavy foot traffic is expected a pathway can be installed.
