Time-Tested Protection for Flat and Low-Slope Commercial Roofs

Built-Up Roofing (BUR) systems have been trusted for over a century to protect commercial and industrial buildings. Known for their multi-layer durability, excellent waterproofing, and UV resistance, BUR systems are a reliable choice for flat or low-slope roofs where long-term performance is key.

At St. Louis Roofing Co., we provide expert installation, repair, and maintenance of BUR systems throughout Missouri and Illinois. Our union-trained crews work with precision and safety to deliver dependable results.

What Is Built-Up Roofing?

BUR is a layered roofing system made by alternating sheets of bitumen (asphalt or coal tar) with reinforcing fabrics such as fiberglass or organic felts. The final surface can be finished with gravel or a reflective coating. These multiple layers create a strong, watertight, and fire-resistant system that performs well in a wide range of climates.

Why Choose Built-Up Roofing?

Proven Longevity – BUR systems can last 20–30 years with proper maintenance

Superior Waterproofing – Multiple layers provide excellent protection against leaks

UV & Fire Resistance – Top coatings and gravel layers reflect sunlight and resist flame spread

Heavy-Duty Durability – Ideal for roofs with frequent foot traffic or harsh exposure
