What technical requirements define how to install modified bitumen roll roofing for asphalt or bitumen modification?
To install modified bitumen roll roofing, ensure the substrate is clean, dry, and structurally sound. Use a torch or hot air welder for heat-applied systems, or a self-adhesive method for cold applications. Overlap seams by at least 3 inches and ensure proper adhesion. Install underlayment as needed, and maintain a minimum slope of 1:12 for drainage. Follow manufacturer guidelines for specific installation techniques and safety precautions.
