Several process parameters influence the installation of modified bitumen roofs, including temperature, substrate preparation, and application method. The ambient temperature affects the viscosity of the bitumen, impacting adhesion and flow. Proper substrate preparation ensures optimal bonding and prevents moisture infiltration. Additionally, the application method-whether torch-applied, self-adhered, or cold-applied-determines the installation’s effectiveness and durability. Monitoring these parameters is crucial for achieving a reliable and long-lasting roofing system.
