Modified Bitumen Roofing Systems for Commercial and Industrial Buildings
Durable Roofing Solutions with Modified Bitumen
Modified bitumen roofing has been a trusted solution for commercial and residential buildings for nearly 50 years. Originally developed in Europe in the late 1960s, modified roofing systems became popular in the United States by the early 1980s. At MRB Contractors, we install modified bitumen systems that offer proven durability, high resilience to foot traffic, and exceptional performance on low-slope and flat roofs.
Designed to withstand heavy usage, modified bitumen roofs are an ideal choice for industrial facilities, rooftops with HVAC equipment, and high-traffic maintenance areas.
Understanding Modified Bitumen Roof Systems
Modified Bitumen (MB) systems are composed of asphalt reinforced with modifiers to give it rubber-like flexibility and strength. The two most common modifiers are:
- APP (Atactic Polypropylene)
Provides enhanced UV resistance and flexibility. - SBS (Styrene Butadiene Styrene)
Adds rubber-like properties for superior elasticity and strength.
Modified bitumen systems can be installed as:
- Single-Ply, Two-Ply, or Three-Ply systems, depending on the substrate and project requirements.
- Hybrid Systems, combining modified membranes with traditional BUR layers for added tensile strength and flexibility.
Where Modified Bitumen Excels
- Flat and Low-Slope Roofs
Ideal for residential patio covers, decks, and commercial roofs with minimal pitch. - High-Traffic Areas
Durable enough to handle frequent maintenance foot traffic around HVAC units and rooftop equipment. - Industrial Facilities
Proven performance in demanding, heavy-use environments.
