What technical requirements define modified bitumen roofing price for asphalt or bitumen modification?

The price of modified bitumen roofing is influenced by several technical requirements, including the type of polymer used for modification (such as SBS or APP), the thickness of the membrane, and the manufacturing process. Additionally, factors like the roofing system’s fire resistance, UV stability, and flexibility at low temperatures also play a crucial role. Quality control standards and certifications can further impact costs, as higher quality materials typically command a premium price.
