What's a common challenge when installing BUR roofs in hot climates?

In hot climates, one of the most significant challenges when installing Built-Up Roofing (BUR) is the heat-related softening of materials. BUR systems typically consist of multiple layers of bitumen and reinforcing fabrics, which can include asphalt or tar. In high temperatures, these materials may soften excessively, making them more malleable and potentially compromising their structural integrity and adhesion during installation.

When the material softens too much, it can lead to difficulties in achieving a proper bond between layers, risking delamination or poor performance once the roofing system is in service. Moreover, softening can make the system more susceptible to damage from foot traffic or environmental factors, leading to premature degradation or failure of the roofing system.

This challenge emphasizes the need for careful planning and potentially adjusting installation techniques or materials to ensure performance and longevity when working in hot climates. Choosing appropriate materials designed to withstand higher temperatures or scheduling installations during cooler parts of the day can be strategies to mitigate this issue.
