Commercial Flat Roofing Materials Compared

Not sure which commercial flat roofing material you need? Here are some pros and cons to three of the most common membrane roofing materials.


commercial flat roofingEPDM (ethylene propylene diene terpolymer) roofing is a synthetic rubber membrane that has been used for decades. In addition to roofing, EPDM rubber is often used in seals, tubing, and hoses for garden, automotive, and other industries. The material is known for its resistance to water and sunlight, making it a long-lasting roofing option. Available in traditional black or reflective white, EPDM roofs are simple to install and fairly affordable.

Modified Rubber

Also known as modified bitumen, modified asphalt, or modbit, modified rubber is an asphalt-based roofing material that provides a better alternative to built up roofs. Modified rubber roofs are made from asphalt and various additives that make it rubber-like and flexible. These systems can be heat welded, hot applied, or cold applied. They offer more surface options, so if you want a “cooler” roof, modbit may be a better option than EPDM.


TPO (Thermoplastic Polyolefin) roofing is a single-ply membrane system that is one of the most affordable options. It is also preferred by many because of its reflective nature, which can reduce cooling costs for your building. TPO can be fully adhered or mechanically attached, and it usually comes in much smaller rolls than EPDM roofing. It is a newer material, but has shown good results when it comes to repelling water, sunlight, and other debris.
