Modified Bitumen Roofing
Modified bitumen (MB) roofing is a highly durable solution that is extensively used in commercial roofing. Its roots trace back to the BUR roofing system, but it has been enhanced with modern technologies to offer superior protection and longevity.
- Long-lasting
- Withstands heavy foot traffic
- Easily maintained
- Flexible installation options
The two most common types of MB roofing are APP (Atactic Polypropylene) and SBS (Styrene Butadiene Styrene). APP is applied using a torch, while SBS is applied with hot asphalt or cold adhesive and has superior flexibility.
MB roofing is renowned for its strength and durability. Each layer of bitumen acts as a water-resistant barrier, ensuring the building’s interior remains dry even in harsh weather conditions. This roofing system can withstand heavy foot traffic, making it ideal for commercial buildings where frequent rooftop access is required.
Another significant advantage of MB roofing is its ease of maintenance. In the event of damage, small sections can be easily repaired or replaced, minimizing downtime and costs. MB roofs are also resistant to punctures and tears, adding to their overall lifespan.
The top layer reflects the sun’s rays, offering excellent thermal performance, helping to maintain a consistent building temperature and reduce energy consumption. This reflective property makes MB roofing a more environmentally friendly option.
In terms of installation, MB roofing systems can be fully adhered, mechanically attached, or torch-applied, providing flexibility based on the building’s specific requirements and the climate conditions. An experienced commercial roofing contractor can easily determine which methods and materials will best suit your specific application.
