Bitumen modified roofing is applied through a process that involves heating the modified bitumen to a workable temperature, typically between 350°F and 450°F (175°C to 230°C). The material is then applied using a torch, hot asphalt, or self-adhesive methods, ensuring proper adhesion to the substrate. The modification process enhances the bitumen’s elasticity and durability, allowing it to withstand temperature fluctuations and UV exposure, ultimately extending the lifespan of the roofing system. Proper installation techniques are crucial for optimal performance.
