When you plan a commercial roofing installation, you have several materials to choose from. Modified bitumen is a popular option for businesses. If you’re unfamiliar with this product, here’s a brief introduction to help you determine whether it’s right for your property.

What Is Modified Bitumen Roofing?

Bitumen is a dark and viscous petroleum product that binds asphalt and gives it its color. Modified bitumen roofing consists of layers of bitumen paired with plastic or rubber polymers, glass fiber, and polyester. Together, these materials create a single-ply, flexible membrane.

There are two main types of modified bitumen membranes. Atactic polypropylene (APP) is applied using heat torches and offers greater resistance to the sun’s radiation, enjoying a longer life span. Styrene-butadiene-styrene (SBS) is applied cold, has an adhesive backing, and is more flexible, typically resulting in simpler installation and lower labor costs. Its flexibility also makes it better able to withstand building expansion and contraction due to temperature changes.

What Are Its Benefits?

Modified bitumen is ideal for commercial roofing because it offers exceptional value and durability. It’s entirely waterproof and should last around 20 years with little to no maintenance required. It resists ultraviolet (UV) rays and extreme temperatures without becoming brittle, and absorbs impacts—such as from falling tree branches—without cracking.

The material also contains an insulating layer that prevents heat transfer. This feature helps prevent heat loss and gain in the summer, helping your business save on cooling costs.
