Modified bitumen roofing is a type of asphalt-based roofing material that has been modified with polymers to enhance its performance. It is commonly used in low-slope or flat roof applications and is known for its durability and weather resistance. The polymers added to the asphalt can include atactic polypropylene (APP) or styrene-butadiene-styrene (SBS), which give the material added flexibility, strength, and resistance to temperature fluctuations. Modified bitumen roofing is typically installed in multiple layers, with each layer providing additional protection against water infiltration and other environmental factors. This type of roofing is often applied using heat-welding techniques or cold adhesives, depending on the specific product and installation method.
Modified bitumen roofing is available in various forms, including rolls, sheets, and shingles, making it a versatile option for different types of roofs. It can be installed as a single-ply membrane or as part of a multi-ply system, providing options for different budget and performance requirements. The installation process typically involves heating the material to activate the adhesive and create a strong bond with the roof substrate. This type of roofing is known for its ease of installation and repair, making it a popular choice for commercial and residential properties alike.
