Which advantage does BUR offer compared to single-ply roofing systems?

Built-Up Roofing (BUR) systems are known for their robust construction, which typically involves multiple layers of bitumen and reinforcing fabrics. This layered structure provides superior durability, resulting in greater resistance to punctures and impact compared to single-ply roofing systems. The multiple layers create a thicker membrane that can better withstand physical stress from hail, foot traffic, or debris, making BUR a strong choice for roofing applications where such resistance is a priority.

In contrast, while single-ply systems can be lightweight and easier to handle, they often do not provide the same level of puncture resistance because they typically consist of a single layer of thermoplastic or elastomeric material. Therefore, BUR's multi-layer system gives it an edge in terms of protecting against physical damage, making it ideal for certain environments and applications where durability is crucial.
