Two of the most popular flat roofing options today are modified bitumen and TPO (thermoplastic polyolefin). Each has its own set of defining traits and unquestionable strengths, making either of them an excellent choice for low-slope roof applications.
Here’s what makes each an excellent commercial roof installation option:
Incredible Durability – Modified bitumen systems share the proven performance of classic built-up roofs (BURs). They mix a modifier with high-quality asphalt in lieu of a heavy gravel cover to weather well. Strengthened by a polymer-reinforced roof wear layer, they boast excellent elasticity and flexibility to resist damage due to low temperatures.
Seamless Design – Rolls of modified bitumen overlap one another to prevent leakage effectively. When their joints are fastened as intended, they can protect your building’s interior from the elements with minimal commercial roof maintenance.
Speedy Installation – Modified bitumen roofs are as tough as BURs but not as complicated to apply. Of course, their installation requires specialized skills and tools, but they’re less labor-intensive and prone to errors.
Exceptional Energy Efficiency – The biggest claim to fame of TPO roofs is solar reflectivity. They share this quality with other single-ply membrane systems, but its aesthetic versatility separates them. They generally come in light colors like white, but they’re likewise available in dark ones, including black, without sacrificing their excellent energy performance.
Damage-Resistant Formulation – TPO products vary from manufacturer to manufacturer, but experienced commercial roofing contractors talk frequently about how they repel natural threats, such as mold and dirt, well. They’re also flexible enough to handle building settling, allowing the roof to expand and contract without losing their structural integrity.
Economical Pricing – Affordability is another reason TPO membranes magnetize property owners. While they share many qualities with PVC systems, they typically come at a lower cost.
