Modified Bitumen Roofing in Dallas, TX
Modified bitumen roofing has changed over the past 50 years or more from being a novel experiment to one of the most widely used commercial roofing systems. Millions of projects around the world have chosen it as their roofing material of choice due to its high tensile strength, long lifespan, and very simple installation. But what precisely is modified bitumen roofing, and why is it better than other types of roofing?
Application of Modified Bitumen Roofing
Modified bitumen is often sold as rolls of membrane that are attached to the substrate using an adhesive. In some circumstances, the material can self-adhere. The material can also be heat welded or cold-adhered.
Additionally, some modified bitumen membranes may be mechanically fastened. A base layer and a cap layer are often required for applications, although in some circumstances it may be installed in a multi-ply system with three or more layers.
Modified Bitumen Roofing Types
APP Membrane Roofing
Membranes made of atactic polypropylene (APP), sometimes known as “plastic asphalt” membranes, are composed of asphalt mixed with plasticized polymers that expand under high temperatures. APP is a wonderful option for buildings looking to achieve a “cool roof” effect because it is UV-resistant.
SBS Membrane Roofing
Styrene-butadiene-styrene, or SBS, roofing is best thought of as “elastic” or “rubberized” asphalt. For a membrane with a natural elasticity and flexibility, asphalt and polymerized rubber are combined. SBS is a fantastic option for structures whose roofs experience large temperature swings as well as roofs exposed to stronger winds.
