Although built-up roofs are the oldest type of low-slope roofing systems, gaining an understanding of the advantages and characteristics of modified bitumen membranes will help you select the asphalt roofing system that improves performance and saves on installation costs over traditional asphalt roofs. Learn how “mod bit” roofs, whether APP or SBS, provide improved durability with stronger reinforcements, resist hail and traffic damage, and provide factory-controlled quality manufacturing.

Upon completion of this course, the Learner should be able to:

• Describe how asphalt has been used in built-up roofing (BUR) and modified bitumen products, such as APP and SBS, in terms of physical characteristics and performance advantages.
• List the advantages and disadvantages of the various attachment types: hot asphalt, heat fusion, and cold process.
• Explain the basic details of the seaming techniques used for modified bitumen roofing systems.
• Explain handling hard-to-flash details with liquid flashing products.
• Describe the environmental attributes of asphalt-based systems.
