What Is Modified Bitumen Torch Down Roofing?
Modified Bitumen, commonly called Mod Bit, is one of the most trusted roofing systems for commercial flat and low-slope roofs. Built with reinforced asphalt membranes and advanced polymer technology, it creates a highly durable roofing assembly designed to resist leaks, ponding water, hail, wind, foot traffic and ultraviolet exposure.
During installation, each membrane is professionally heat welded using a roofing torch. This process fuses the seams together to create a continuous waterproof barrier that performs exceptionally well in demanding commercial environments. Unlike many roofing systems that rely on adhesives or exposed fasteners, torch-applied seams form a strong bond that helps reduce the likelihood of water intrusion.
Modified Bitumen roofing is ideal for office buildings, retail centers, warehouses, manufacturing facilities, churches, schools, apartment complexes, condominiums and many other commercial properties throughout Indianapolis and Central Indiana.
SBS VS. APP Modified Bitumen
SBS Modified Bitumen offers exceptional flexibility and performs extremely well in colder climates. APP Modified Bitumen provides outstanding UV and heat resistance. Our commercial roofing specialists will inspect your building and recommend the system that delivers the best long-term value for your property and budget.
Call (317) 907-9111 for expert guidance.
Torch Down Application Process
One of the biggest advantages of Modified Bitumen roofing is the torch-down application method. During installation, our trained commercial roofing crews use professional roofing torches to heat the underside of each membrane, creating a permanent bond between the roofing layers and the substrate. This process forms a seamless, watertight roofing system that delivers outstanding protection against leaks, ponding water, wind uplift, and harsh weather.
Every project begins with proper roof preparation, including removing damaged materials when necessary, repairing the roof deck, installing the base sheet, and carefully heat-welding each successive layer. We pay close attention to flashing details around roof penetrations, drains, parapet walls, HVAC equipment, and expansion joints to ensure complete waterproof protection.
Because torch-down roofing uses an open flame, installation should only be performed by experienced, trained professionals who follow manufacturer specifications and strict safety procedures. Our crews use industry best practices to protect your property while delivering a durable roofing system designed to provide 20–30+ years of dependable performance.
