Built-Up Roofing Systems
Time Tested Performance
Built-Up Roofing systems (tar and gravel) inherent redundancies forming the most reliable roofing system for buildings with low-slope roofs. In use since 1840, BUR systems consist of multiple plies of roof felts made of bitumen-saturated organic fiber, fiberglass, or polyester felt laminated together with bitumen. The system is assembled onsite by lapping the piles and bitumen in several layers. Then covered with a surface coating called a cap sheet to create the multi-layer water impervious membrane.

RAMCON assembles BUR systems to meet a broad range of designs. Over the years, we have installed tens of millions of square feet of both hot applied (with hot asphalt) and cold applied (with cold process adhesives) roofing systems. Our clients choose BUR because of its low cost of ownership, limited maintenance requirements, and ability to withstand foot traffic.
