Built-Up Roofing (BUR)

The original built-up roof, engineered for today's buildings

Strong Contractors installs, replaces and repairs built-up roofing systems for commercial, industrial and institutional facilities. Built-up roofing, commonly called BUR, uses multiple reinforcing plies bonded with hot asphalt or an approved cold-applied adhesive and finished with aggregate, a cap sheet or another protective surfacing. It is commonly selected for its puncture resistance, traffic tolerance and long history of performance on demanding low-slope roofs. ‘

Common Applications:

Industrial and Manufacturing Facilities
Schools and Institutional Buildings
Hospitals and Healthcare Facilities
Commercial Buildings
High-Traffic Roof Areas
Roofs with Extensive Mechanical Equipment
Roofs Requiring a Durable, Multilayer Assembly
Complete Replacement and Phased Reroofing Projects

Strong Contractors' Approach to Built-Up Roofing (BUR)

Built Layer by Layer for Continuity and Redundancy

Built-up roofing develops its strength through multiple reinforcing plies bonded with bitumen and protected by a finished surfacing. Strong controls each layer as it is installed because deficiencies in asphalt application, ply placement or adhesion can become concealed as the assembly is built.

Understand the Existing Conditions
We evaluate the substrate, insulation, drainage, traffic demands and roof configuration before beginning the assembly.
Control Bitumen and Ply Placement
Asphalt or approved adhesive is applied consistently while plies are embedded, lapped and offset.
Maintain Multi-Ply Continuity
Laps, flashings and reinforced conditions are integrated without aligning weaknesses through the membrane.
Complete the Protective Surface
Aggregate, cap sheet or coating is installed to protect the finished membrane from weathering and physical damage.
