What is Modified Bitumen Torch-Down Roofing?

Modified bitumen torch-down roofing is a flat or low-slope roof system made from asphalt blended with polymer modifiers for enhanced flexibility and strength. The “torch down” method involves heat-welding the material to create a seamless, waterproof layer. This process resists heavy rain, standing water, intense UV rays, and seasonal temperature changes.


Thanks to its proven performance, modified bitumen roofing has been a preferred choice for decades among property owners seeking long-lasting protection with minimal maintenance. It’s ideal for commercial properties, warehouses, apartment complexes, and residential homes with flat or low-slope roofs.
