What is Modified Bitumen Roofing?
Modified Bitumen (MB) roofing is an asphalt-based roofing system designed for structures with low-slope roofs. MB roofing membranes have been used in the US since the mid 1970s.

Constructed with fiberglass and coated with MB asphalt.
A extra-strength bonding agent that creates a waterproof barrier.
Increases weather-resistance and shields your roof from UV rays.
- Tear Resistance: A major advantage MB roofing offers over other commercial roofing systems is its tear resistance. The combination of fiberglass and/or polyester reinforcement layers under its surface creates a strong, tear-resistant roofing surface. Additionally, this quality makes MB roofing an ideal choice for low-sloped roofs that sustain high foot traffic or rooftop equipment.
- Flexibility: Flexible low-slope roofing is impact resistant as well as highly resistant to temperature changes. MB can expand and contract without losing shape or structure.
- Energy Efficiency: MB can be installed with a “cool roof” treatment like solar reflectance, resulting in reduced indoor cooling requirements.
- Waterproof: MB is one of the top-chosen commercial roofing options, as bitumen is naturally waterproof.
