How can high surface temperatures impact a BUR system?

High surface temperatures can significantly accelerate the aging process of the materials used in a built-up roofing (BUR) system. As the temperature rises, the physical and chemical properties of roofing materials can change more rapidly, leading to issues like brittleness, cracking, and loss of flexibility. This accelerated aging can shorten the lifespan of the roofing system and may compromise its effectiveness against leaks and other forms of weathering.

Understanding how high temperatures affect BUR systems is crucial for maintaining the integrity and performance of the roof over time, ensuring that it provides adequate protection and requires less frequent replacement or repair.
