Modified Bitumen Roofing

Rubberized asphalt protection with proven flexibility

Strong Contractors installs, replaces and repairs modified bitumen roofing systems for commercial, industrial and institutional facilities. Modified bitumen is an asphalt-based membrane reinforced with polymers to improve flexibility, strength and weather resistance. It is commonly selected for complex roof layouts, smaller roof areas, frequent maintenance traffic and conditions requiring a durable, flexible membrane system.

Common Applications:

Commercial and Institutional Buildings
Schools and Municipal Facilities
Healthcare Facilities
Industrial Buildings
Roofs with Complex Penetrations and Transitions
High-Traffic Maintenance Areas
Smaller or Irregular Low-Slope Roofs
Repair, Replacement and Phased Reroofing Projects

Strong Contractors' Approach to Modified Bitumen Roofing

Matched to the Membrane, Application Method and Roof Geometry

Modified bitumen systems may use different membrane formulations, attachment methods and surfacing options. Strong coordinates the substrate, base sheet, membrane, application method, laps, flashings and protective finish around the roof configuration and project conditions.

Understand the Roof Conditions
We evaluate substrate compatibility, drainage, penetrations, maintenance traffic and application constraints.
Select the Appropriate Application
Torch, hot asphalt, cold adhesive, self-adhered or mechanically attached methods are matched to the specified membrane and site conditions.
Control Bonding and Laps
Membrane alignment, adhesion, side laps and end laps are managed to maintain continuous coverage.
Reinforce Complex Details
Corners, penetrations, curbs, transitions and changes in plane receive focused reinforcement and detailing.
