Soprema 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, either through torching or using a hot air welder, to activate the adhesive properties. The membrane is rolled out and pressed onto the substrate, ensuring a seamless bond. Overlapping seams are then heated to create a watertight seal. Finally, the installation is inspected for quality and integrity to ensure durability.
