Commercial Roofing Contractors are no strangers to Built-Up Roofs. These systems have been around longer than any other low-slope membrane and with good reason. They have a 100+ year record of remarkable performance and have proven very adaptable as well. While building design, roofing materials, application techniques and environmental standards have all continued to evolve, BUR has remained relevant thanks in part to its inherent adaptability. Our polymer-modified product, ENDURAflex HT SEBS, is a prime example of how modern technologies have improved on a time-tested and trusted system. 

Let’s discuss some of the many advantages that polymer modified asphalts bring to the equation.  

Specifically, the “E” (Ethylene) molecule in SEBS is the key component that allows for superior UV resistance and overall thermal stability of the product. This UV resistance is the key to performance in extreme, hot environments with lots of sunshine. The thermal stability means that contractors can use the same equipment they always have. No expensive jacketed kettles to buy or maintain. Finally, this molecule also bonds with the Butylene component, giving the material its remarkable elasticity, ability to self-heal and resistance to hail damage. The material also exhibits outstanding low temperature flexibility and fracture resistance again reinforcing “greatly improved performance in the most extreme conditions.”
