Siplast SBS modified bitumen roofing is applied through a multi-step process. First, the substrate is prepared to ensure proper adhesion. The modified bitumen membrane is then heated using a torch or hot air, allowing it to become pliable. It is rolled out onto the substrate, ensuring proper alignment and overlap. The edges are sealed to create a waterproof barrier. This process enhances the roofing’s durability and flexibility, making it suitable for various environmental conditions.
