No, TPO (thermoplastic polyolefin) is not the same as modified bitumen. TPO is a type of single-ply roofing material that is made from a synthetic rubber polymer, while modified bitumen is a type of asphalt-based roofing material.
TPO tends to be white or light gray in color and is heat-welded in order to create a seamless, waterproof membrane on the roof. Modified bitumen is typically black in color and is made up of asphalt layered with a protective coat of either polyester or fiberglass.
Modified bitumen can be applied warm or cold and is usually applied with a torch-down method. Both materials have their advantages and disadvantages and should be discussed with a professional roofer to determine the best type of roofing material for a given situation.
Can you install TPO over modified bitumen?
Yes, it is possible to install TPO over modified bitumen. Modified bitumen is a type of asphalt-based membrane that is often used for flat roofing. TPO (thermoplastic olefin) is a single-ply membrane that is touted for its superior waterproofing, resistance to heat and UV light, and relatively low cost when compared to other single-ply systems.
Before TPO is installed, it is important to thoroughly inspect the existing modified bitumen membrane to check for existing defects such as cracks, splits, punctures, and water ponding. If any of these issues exist, they should be properly corrected before installing the TPO membrane.
The TPO membrane should be fully adhered or mechanically fastened to the underlying modified bitumen, with the recommended attachment pattern and spacing. Additionally, all penetrations and seams of the TPO membrane should be properly sealed with compatible compounds to ensure that the roofing system is fully waterproofed.
As with any roofing system, to ensure it will last and perform as expected, the TPO membrane should always be installed by an experienced roofing professional.
Is TPO roof better?

Additionally, there are several aesthetic options available based on the type of modified bitumen used. Such options can include slate, wood shake, and even metal.
How do you identify a modified bitumen?
Identifying a modified bitumen involves looking for certain distinct characteristics. Modified bitumens are typically made from asphalt and resins which are combined to create a hybrid material that combines the properties of both materials.
These hybrid materials, compared to regular asphalt, tend to be more resistant to cracking and crazing. They also tend to be more pliable, and are therefore able to handle heavier loads and stresses.
In terms of appearance, modified bitumen typically have a thick, glossy, and almost tar-like consistency. At times, other components such as rubber, glass fibers, or polymers, are added to increase the flexibility of the material.
Modified bitumen can also often be identified by its malleability and ability to be easily compressed by hand.
What is modified bitumen flat roof?
Modified bitumen flat roof is an upgraded version of the traditional built-up roof (BUR) and uses slag, asphalt, or rubber-modified asphalt for reinforcement. Modified bitumen flat roof is the most common flat-roof system used in North America and comes in two basic varieties: cold-applied, and hot-applied.
The cold-applied variety is applied with a roller, or with a hand or mechanical sprayer, and comes in a variety of colors and sizes. Hot-applied varieties are often used in new constructions and industrial roofing applications.
Modified bitumen flat roof systems are designed to be more durable and energy-efficient than traditional flat roof systems. They are less prone to cracking, tearing, and other types of damage and can last much longer than traditional flat roof systems.
