What is a potential disadvantage of BUR roofing systems?

The correct answer identifies a potential disadvantage associated with BUR roofing systems due to their inherent characteristics. BUR roofing consists of multiple layers of felt and asphalt, which contributes significantly to its overall weight. This added weight can present challenges during installation, requiring careful handling and sometimes additional structural support to accommodate the heavier materials.

Furthermore, the complexity of the installation process with multilayer systems can lead to longer installation times and the need for specialized labor, often increasing labor costs and the potential for human error.

While other options present valid concerns within the context of roofing systems—such as susceptibility to punctures or limited color choices—the weight of BUR systems and the consequent installation difficulties are particularly noteworthy drawbacks that can impact the overall practicality and cost-effectiveness of the roofing solution.
