When it comes to protecting your commercial property, choosing the right roofing membrane is a critical decision. TPO, EPDM, and PVC are the most commonly used low-slope roofing systems in the industry — but which is best for your building? At CP Rankin, we break down the key differences to help property managers and facility professionals make informed, cost-effective decisions.
TPO Roofing (Thermoplastic Polyolefin)
What Is It?
TPO is a single-ply white membrane known for its reflective surface and affordability. It’s one of the most widely installed roofing systems in the country.
Key Advantages:
-
Energy efficient due to its white, reflective surface
-
Hot-air welded seams offer strong water resistance
-
Resistant to UV, mold, and punctures
-
Cost-effective and recyclable
Best For:
Buildings in warmer climates, or facilities seeking energy efficiency and sustainability.
EPDM Roofing (Ethylene Propylene Diene Monomer)
What Is It?
Often called “rubber roofing,” EPDM is a black synthetic membrane known for its flexibility and longevity.
Key Advantages:
-
Extremely durable and weather-resistant
-
Ideal for colder climates due to its flexibility
-
Large sheet sizes = fewer seams
-
Low material cost
Best For:
Buildings with large spans, minimal rooftop traffic, and colder environments.
PVC Roofing (Polyvinyl Chloride)
What Is It?
PVC is a durable single-ply membrane with excellent chemical and grease resistance, making it a favorite for restaurants and industrial facilities.
Key Advantages:
-
Excellent resistance to chemicals and oils
-
Strong heat-welded seams
-
High puncture resistance
-
Naturally reflective for energy savings
Best For:
Facilities with chemical exposure or frequent rooftop foot traffic.
