How is app modified bitumen roofing systems applied in asphalt or bitumen modification processes?

App modified bitumen roofing systems are applied through a multi-step process. First, the substrate is prepared to ensure proper adhesion. The modified bitumen membrane is then rolled out and aligned. Heat is applied using a torch or hot air welder to activate the adhesive properties of the membrane. As the material is heated, it bonds to the substrate and overlaps with adjacent sheets, creating a seamless, waterproof layer. Proper installation ensures durability and performance in various weather conditions.
