Modified Bitumen

---

Modified Bitumen 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.

 

A few manufacturers have begun offering reflective cap sheets which have a bright white "chip" surfacing instead of the standard granule. Another option for those seeking "green" roofs is the application of a reflective coating over a new or existing roof.

 

Mod bit roofs are sturdy and can usually stand up to traffic on roofs that have a large number of mechanical units.
