Modified Bitumen Membrane Construction
Modified bitumen membranes are considered a superior factory made material. These membranes are significantly easier to install reducing field application inconsistencies. They are generally completed with a two part system as opposed to a three or four ply system required in built-up membrane construction. Modified bitumen roofing systems can be installed using cold adhesives,torched into place, or hot-mopped. Modified bitumen membranes resist roof punctures from mechanical damage, foot traffic, and fastener retraction.
