Modified Bitumen Roofing
Time-tested, multi-ply asphalt roofing systems engineered to withstand heavy roof traffic and severe physical impacts.
System Specification Overview
Modified Bitumen (Mod-Bit) systems combine asphalt and polymer modifiers to create robust, multi-layered membranes. Mod-Bit is ideal for commercial roofs with high foot traffic, heavy HVAC mechanical equipment, or buildings prone to severe hail and debris impacts. Metroplex offers professional cold-applied, hot-mopped, and torch-down Mod-Bit installations.
Key Engineering Benefits
- Multi-ply layered protection (usually 2 or 3 plies) for redundant water security
- Extreme puncture, tear, and foot-traffic resistance
- Excellent performance in both cold and high-heat cycles
- Lower maintenance overhead for heavily trafficked utility roofs
- Excellent tensile strength and structural reinforcement

System FAQ & Specifications
WHAT IS THE DIFFERENCE BETWEEN BUILT-UP ROOFING (BUR) AND MODIFIED BITUMEN?
Modified Bitumen incorporates synthetic rubber (SBS) or plastic (APP) polymers which give it greater flexibility and crack resistance compared to traditional gravel-topped BUR.
DOES IT COME IN REFLECTIVE COOL OPTIONS?
Yes, we offer premium mineral granule cap sheets with specialized highly reflective coatings to meet cool roof requirements.
