What Is Modified Bitumen Roofing?
Modified Bitumen roofing is an asphalt-based roofing system engineered specifically for commercial flat and low-slope roofs. It was developed as an advancement of traditional Built-Up Roofing (BUR) systems by incorporating polymer-modified asphalt to improve flexibility, durability, and weather performance.
The two most common types of Modified Bitumen roofing systems are SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene). These systems are designed to provide enhanced waterproofing protection while offering greater flexibility and performance than traditional asphalt roofing materials.
Modified Bitumen roofing systems can be installed using several application methods, including torch-applied, cold-applied, self-adhered, and mechanically attached systems, depending on the project’s requirements and building conditions.
Because of its proven performance and ability to withstand demanding weather conditions, Modified Bitumen remains one of the most trusted roofing systems for commercial properties throughout Minneapolis and Minnesota.
Benefits of Modified Bitumen Roofing
Exceptional Waterproofing Protection
One of the biggest advantages of Modified Bitumen roofing is its ability to create a durable waterproof barrier. Multiple layers and reinforced membranes help protect commercial buildings from leaks, moisture intrusion, and weather-related damage.
Enhanced Flexibility
Modified Bitumen roofing remains flexible even during significant temperature fluctuations. This flexibility helps reduce the risk of cracking and membrane damage over time.
Strong Weather Resistance
Minnesota commercial roofs must withstand snow, ice, rain, wind, and seasonal temperature extremes. Modified Bitumen roofing is specifically designed to perform well in these challenging environmental conditions.
Durable Commercial Performance
Modified Bitumen systems provide excellent resistance to wear and tear, making them suitable for many commercial and industrial applications.
Easy Maintenance and Repair
Compared to some commercial roofing systems, Modified Bitumen roofing can often be repaired and maintained efficiently, helping property owners extend roof lifespan and reduce long-term ownership costs.
Long-Term Value
When properly installed and maintained, Modified Bitumen roofing systems can deliver years of reliable performance while helping protect valuable commercial assets.
SBS vs APP Modified Bitumen Roofing
Understanding the differences between SBS and APP Modified Bitumen roofing can help building owners select the best roofing system for their property.
SBS Modified Bitumen Roofing
SBS (Styrene-Butadiene-Styrene) Modified Bitumen incorporates rubber-like polymers into the asphalt membrane. This creates a highly flexible roofing system that performs exceptionally well in colder climates.
Benefits of SBS Modified Bitumen include:

Benefits of APP Modified Bitumen include:
- Improved UV resistance
- Enhanced weather resistance
- Excellent heat tolerance
