AOS Superior Roofing installs high‑performance Modified Bitumen (Mod Bit) roofing systems — also commonly known as torch‑down roofing — designed for flat and low‑slope structures. Mod Bit is an asphalt‑based system enhanced with polymers or reinforcing fabrics, giving the membrane superior flexibility, strength, and weather resistance.
At the core of the system is a durable bitumen membrane reinforced with fiberglass or polyester, allowing it to expand and contract with temperature changes while maintaining a reliable, watertight seal. Torch‑down application is one of the most trusted installation methods, providing strong adhesion and long‑term durability.
