    Modified bitumen roofs offer enhanced flexibility and durability compared to built-up roofing systems. The incorporation of modifiers, such as SBS or APP, improves resistance to temperature fluctuations and UV degradation, leading to longer service life. Additionally, modified bitumen systems typically feature easier installation and maintenance, reducing labor costs. In contrast, built-up roofs, while robust, can be heavier and more prone to cracking over time, impacting overall performance in modified asphalt applications.
