What Is Modified Bitumen and What Are Its Main Characteristics?

Designed primarily for low slope and flat roofing applications, modified bitumen is an asphalt-based roofing material that has gained quite a bit of traction in recent years. Its practical qualities are the main reason why it has become as popular as it is today, and ever since it appeared in Europe in the 1960s, experts have been affirming that it’s one of the best commercial flat roofing products out there.

Modified bitumen is designed to withstand harsh weather conditions, and even if it’s exposed to multiple environmental stressors at the same time, its various layers act to protect your building efficiently without caving in to any harmful elements.

Skilled modified bitumen roof Dallas contractors explain that this type of roof is formed from a total of five different layers that together form a nearly impregnable system. The insulation provides thermal resistance, while the modified base sheets and modified bitumen membranes, which are often reinforced with fiberglass, are set in place as the main layers of the roof. A waterproof adhesive formula is added on top along with a UV-resistant surface coating that protects your roof from harmful radiation.

This modern roofing system is surprisingly resilient and dependable, featuring ideal weatherproof qualities and a uniquely impressive high tensile strength that makes it remarkably impact-resistant.
