Modified bitumen is an advanced roofing material created by enhancing standard asphalt with specialized modifiers. These additives replace the natural plasticizers lost during the refining process, giving the material more flexibility and resilience. Reinforced with either fiberglass or polyester, modified bitumen is engineered to deliver strength and long-term performance, making it a dependable solution for low-slope and flat roof systems.
There are two primary categories of modified bitumen roofing, each designed with unique advantages:
SBS (Styrene-Butadiene-Styrene): Known for its rubber-like flexibility, SBS membranes adapt easily to expansion and contraction caused by temperature changes. They’re typically applied using cold adhesives or hot asphalt.
APP (Atactic Polypropylene): APP membranes are highly durable and resistant to aging. They provide excellent long-term protection and are usually installed using a heat-applied torch method.
If you’re looking for a roof that can handle years of exposure with minimal upkeep, modified bitumen is a smart investment. Its flexible design, cost-effectiveness, and straightforward installation make it a reliable option for businesses seeking both performance and value.
