Modified Bitumen (Mod Bit) roofing is the next generation of the tried-and-true built-up roof. Typically comprised of 2-3 plies of asphaltic felts, they can be torch-applied or installed with cold adhesive. Mod bit roofs typically have a granule-surface cap sheet and are available in a variety of colors. Some manufacturers have modified cap sheets with enough solar reflectivity to meet LEED requirements.
