Learn why modified bitumen roofing systems are trusted everywhere

Modified bitumen roof membranes are one of the most common types of single-ply modern commercial roof membranes available. Other common alternatives include PVC, TPO, and metal roofing. By comparison, TPO is both durable, cost effective and easy to adjust and repair.  Modified bitumen is similar to other types of asphaltic or synthetic rubberized materials, but the modified part of the terminology indicates that the bitumen component of the modified membrane has undergone a exposure to high pressure air at the time of manufacturing. That process gives increase strength and resilience to the modified bitumen membrane material.

This is similar to a simple historic building roof layout with slope starting high at the front and running lower at an angle to the rear of the building.  Modified bitumen membranes work well for a single direction roof slope.  In contrast, roof valleys, crickets, and ridges create a multi-directional roof layout which requires internal drains and / or multiple terminations.
