What Is Built-Up Roofing?
Built-up roofing is a proven commercial roofing system designed for flat and low-slope roofs.
BUR systems are constructed using multiple layers of reinforcing material and bitumen to create a strong, redundant waterproofing system. Traditional systems are often finished with a protective layer of gravel or aggregate.
The result is a durable commercial roof designed to provide long-term protection against water, weather, UV exposure, and everyday rooftop conditions.
Benefits of Built-Up & Tar and Gravel Roofing
Multi-Layer Protection
Multiple roofing layers create a durable system with added protection against leaks and water intrusion.
Proven Durability
BUR has a long history of use on commercial, industrial, and multifamily buildings.
Strong Waterproofing
Multiple layers of bitumen and reinforcement provide dependable protection for flat and low-slope roofing applications.
UV & Surface Protection
Aggregate-surfaced systems help protect the roofing membrane from sunlight, weather exposure, and physical damage.
Repairable & Maintainable
Many aging BUR systems can be repaired or restored when the underlying roofing system remains in serviceable condition.
Cost-Effective Options
Depending on your roof’s condition, targeted repairs or restoration may help extend its service life and delay the cost of complete replacement.

Repair, Restore, or Replace?
Your Commercial Roof May Have More Life Left
An aging tar and gravel roof does not automatically need to be replaced.
If the roofing system and underlying components remain in suitable condition, repairs or restoration may provide a more economical way to extend the roof’s service life.
Our commercial roofing team will inspect your roof, document problem areas, and help determine whether repair, restoration, or replacement makes the most sense for your property.

Commercial BUR Roof Repair
Leaks in built-up roofing systems can develop around flashing, penetrations, drains, seams, deteriorated roofing materials, and other vulnerable areas.
Our team works to identify the source of the problem—not simply cover the visible symptoms.
Addressing problems early can help prevent water intrusion from damaging insulation, decking, equipment, and interior areas of your building.
