What is not recommended during the installation of a BUR system in high slippage climates?

• A. Use of modified bitumen
• B. Phased construction
• C. Low-slope applications
• D. Increased asphalt use

Answer: (B)

During the installation of a built-up roofing (BUR) system in high slippage climates, it is crucial to ensure that the roofing system adheres properly to the substrate and withstands various environmental factors. Phased construction can lead to complications such as thermal expansion and contraction issues, allowing for potential slippage and improper adhesion between layers. This can compromise the integrity of the roof system, leading to potential failures. Using modified bitumen can provide better flexibility and adhesion, which are essential in high slippage areas. Low-slope applications are common for BUR systems, and they do not inherently cause issues in slippage climates when properly installed. Increased asphalt use can enhance bonding and make the system more resistant to slippage and movement. Thus, while the other options can be beneficial or standard practice in high slippage climates, phased construction is not recommended as it may create vulnerabilities in the installation and performance of the roofing system.
