Commercial
Modified Bitumen Roofing in Dallas-Fort Worth
Modified bitumen is a proven multi-layer asphalt roofing system designed for flat and low-slope commercial buildings — particularly well-suited to roofs with heavy foot traffic, multiple penetrations, and demanding North Texas weather exposure.
Modified Bitumen — When Durability and Foot Traffic Matter
Modified bitumen roofing systems are the descendant of traditional built-up roofing — but with a modern polymer-modified bitumen membrane that provides meaningfully better flexibility, UV resistance, and puncture resistance than older BUR systems. In the DFW commercial market, modified bitumen is frequently specified for roofs with significant HVAC equipment, maintenance foot traffic, or penetration density — situations where the robust multi-layer assembly provides better long-term protection than a single-ply membrane. Torch-applied, cold-applied, and self-adhered application methods allow the system to be adapted to a range of building types and safety requirements.
What This Service Includes
Torch-Applied Modified Bitumen
Heat-fused application for maximum seam adhesion and waterproofing performance. Appropriate for roofs where open-flame equipment can be safely used.
Cold-Applied Modified Bitumen
Adhesive-applied systems appropriate for buildings with fire suppression systems or open-flame restrictions.
Self-Adhered Modified Bitumen
Peel-and-stick application for situations where both torch and cold-adhesive application present challenges.
Multi-Layer Assembly
Base sheet, modified bitumen cap sheet, and granule surface installed in sequence to create a redundant waterproofing assembly.
Repair & Restoration
Modified bitumen repair using compatible torch or cold-applied patches for seam failures, blisters, and penetration issues.
BUR Overlay & Compatibility
Modified bitumen can be applied over existing built-up roofing systems in appropriate condition — we assess compatibility before recommending.
Signs You May Need This Service
