Modified bitumen roofing, also called mod bit, is an asphalt-based system designed to be weather resistant and stand up to severe conditions. Businesses looking for outstanding durability consistently turn to Elevated Contracting for modified bitumen roofing installations. Mod bit systems are composed of five layers of roofing materials—insulation, plies, sheets of modified bitumen membranes, adhesive, and surfacing.
Similar to built-up roofing (BUR), modified bitumen roofing systems are ideal for commercial low-sloped roofs or flat roof facilities. The thickness of modified bitumen sets it apart from single-ply materials. When including the granulated cap sheet on a standard 2-ply mod bit system, it’s four times thicker than popular flat roofing systems like TPO or EPDM.
