Which factors affect 3 ply modified bitumen roof in asphalt or bitumen modification systems?

Several factors influence the performance of a 3-ply modified bitumen roof in asphalt or bitumen modification systems. Key factors include the type and quality of the bitumen used, the polymer modification (such as SBS or APP), the application method (torch-applied, self-adhered, or cold adhesive), environmental conditions during installation, and the substrate preparation. Additionally, proper detailing and maintenance practices significantly impact the roof’s durability and longevity.
