Several factors influence the attachment of modified bitumen roofs in asphalt or bitumen modification systems. These include substrate preparation, which ensures proper adhesion; ambient temperature during installation, affecting the material’s viscosity; and the type of adhesive or bonding agent used. Additionally, the quality of the modified bitumen itself, including its polymer content and formulation, plays a crucial role. Lastly, environmental conditions, such as humidity and wind, can impact the effectiveness of the attachment process.
