Modified Bitumen Roofing

Rubberized asphalt roofing sheets installed in layers with heat-welded or self-adhered seams for durable low-slope protection.

Modified bitumen is a rubberized asphalt roofing sheet installed in layers, often with a granulated cap sheet on top. It is tough, repairable and has a long track record on low-slope roofs. Owners in Nashville choose it for commercial buildings, flat residential roofs and areas with foot traffic from equipment service.

We begin with a Free Estimate and a survey of the existing roof and deck. We recommend torch-applied, hot-mopped, cold-adhesive or self-adhered installation based on building use and safety, prepare the substrate, install insulation and base sheets and lay the cap sheet with lapped seams. Edges, walls and penetrations are flashed with matching sheets and metal terminations. We follow fire safety procedures closely with any heat application. Safety planning is part of our approach with modified bitumen. When heat is used, we follow fire-safety procedures, keep extinguishers on the roof and watch the area after work is finished. If a building is sensitive to heat, such as one with combustible materials or limited access, we discuss self-adhered or cold-applied options that reduce risk while still delivering a durable roof.

Layered strength

Multiple plies give redundancy, so one layer does not carry the entire waterproofing load.

Foot traffic tolerance

A granulated cap sheet stands up well where technicians walk or service equipment.

Application method

We choose torch, adhesive or self-adhered methods to suit the building and safety needs.

Flashing continuity

Matching base and cap flashings keep walls and curbs tight.
