Modified Bitumen Roofing in Minnesota
Modified Bitumen systems are a modern evolution of the age-old built-up roofing (BUR). Bitumen systems consist of multiple layers of roofing felt embedded in hot-mopped asphalt. Modified Bitumen (MB) roofing is an asphalt-based, close cousin of BUR, designed for buildings with low-slope roof structures in Minnesota.
For more information regarding modified bitumen roofing systems, contact the professionals at Sellers Roofing Company. A typical MB roof includes two layers: a base sheet and a cap sheet.
Types of Modified Bitumen Sheets
- APP (Atactic Polypropylene): A thermoplastic added to asphalt to reflect UV rays and improve cold-weather resistance.
- SBS (Styrene-Butadiene-Styrene): A rubber polymer blended with asphalt, known for flexibility and durability.
APP shares qualities with modern thermoplastic systems.
