Modified Bitumen Roof Systems

Modified bitumen systems combine the redundancy of a traditional asphalt roof with the performance benefits of a polymer-modified membrane. The result is a low-slope assembly that handles chemical exposure, impact, and thermal cycling exceptionally well — which is why it remains a popular choice for commercial and industrial buildings.

Alpine installs both SBS (rubberized) and APP (plasticized) modified systems, applied with torch, hot mop, or cold-process methods depending on the building and code requirements.
