Commercial modified bitumen roofing is applied using a multi-step process that involves the use of polymer-modified asphalt. First, the substrate is prepared to ensure proper adhesion. The modified bitumen sheets are then heated, either by torching or using a hot air welder, to activate the adhesive properties. The sheets are rolled out and adhered to the substrate, overlapping seams are sealed to create a waterproof barrier. Finally, the surface may be coated for UV protection and durability.
