Built-Up Roofing (BUR)
Commonly known as “tar and gravel” roofs, BUR systems have been used for over a century. They consist of alternating layers of hot asphalt and reinforcing felts (often fiberglass or organic), topped with a gravel or mineral-surfaced finish.
Benefits of BUR:
- Long-term durability from multiple waterproofing layers
- Excellent fire and UV resistance
- Outstanding protection against foot traffic and impact
- Ideal for large commercial buildings with flat or low-pitch roofs
Built-Up systems are favored in warehouses, schools, and healthcare facilities where redundancy and lifespan are essential.
Modified Bitumen Roofing (Mod Bit)
Modified Bitumen roofs evolved from BUR technology, combining asphalt with modern polymer modifiers to improve flexibility, especially in extreme temperatures – something Louisville sees in both summer and winter.
Types of Modified Bitumen:
- SBS (Styrene-Butadiene-Styrene): Flexible and resilient; best for freeze-thaw cycles
- APP (Atactic Polypropylene): UV-resistant and durable in high heat
Installation methods include torch-down, cold adhesive or self-adhered sheets – allowing customized solutions for your building.
Why Choose Mod Bit?
- Greater flexibility than BUR
- High tensile strength
- Fast, low-odor installation methods
- Excellent choice as an alternative to a built up roof system
Advantages of Asphalt-Based Roofs
Asphalt systems remain a go-to option for commercial roofing because they consistently perform under pressure:
- Exceptional waterproofing
- UV and storm resistance
- Long-lasting with proper maintenance
- Easy to repair and maintain
- Cost-effective for long-term performance
- Proven track record in Louisville’s commercial climate
