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 the dramatic thermal cycling you see on the Western Slope exceptionally well — which keeps it a popular choice for small commercial and industrial buildings in Glenwood Springs, Carbondale, and Rifle.

Rocky Mountain Exteriors 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.
