Modified Bitumen

A modified bitumen (MB) roofing system is a low-slope roofing system.  It is a very reliable roofing system when correctly installed.  An MB membrane is reinforced with polyester, fiberglass or a combination of the two.  This makeup gives it strength and provides an effective roofing system that is very puncture resistance.

The asphalt, or bitumen, is the waterproofing element.  It has also been improved with polymers.  Sometimes you will see mineral granules or metail foil on the surface with a variety of colors, and you can also see the surface not covered and left smooth.  Although the roof is often referred to as rubber or a rubberized roof, it is not the same as an Rubber EPDM roof.
