What Is Modified Bitumen Roofing?
Modified bitumen is a reinforced asphalt-based roofing membrane designed for flat or low-pitch roofs. It’s composed of asphalt blended with polymers like:
SBS (Styrene-Butadiene-Styrene) –
A rubber-modified membrane that adds flexibility and allows for expansion and contraction with temperature changes.
APP (Atactic Polypropylene) –
A plastic-modified material that improves UV resistance and durability.
These membranes are often reinforced with fiberglass or polyester and can be applied through multiple methods, including:
- Torch-down application
- Cold adhesive application
- Self-adhered membranes
