Built-Up Roof (BUR) Systems

Built-up roofing — multiple layers of bitumen and reinforcing fabric topped with gravel or a cap sheet — is one of the oldest commercial roof systems still in service today. Decades of field history have proven it durable, fire-resistant, and reliable in extreme climates, which keeps it relevant on Western Slope commercial and industrial buildings where heavy snow loads and serious fire performance both matter.

Rocky Mountain Exteriors installs BUR systems for commercial buildings across Glenwood Springs, Carbondale, Rifle, and the broader Roaring Fork Valley. We'll evaluate your existing roof, recommend the right multi-ply assembly, and install it to manufacturer spec.
