TPO vs. PVC: Which is better?


The installation of new roofs usually incorporates roofing materials such as TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride). These cost effective, strong and durable materials will not only help you save money, but also make sure that your roof lasts longer over time. But here comes the difficult part, which one should you choose? TPO or PVC? Let’s find out:

TPO (Thermoplastic Polyolefin)

TPO is an economic and durable roofing material that is environmentally friendly, offers better performance as well as being easy to install. A TPO roofing membrane is specifically designed to include the advantages of a rubber roof, combined with hot-air weldable seams for increased durability. The best features of TPO have been adopted from its direct competitors, PVC and EPDM.

Offering innovative, energy efficient and cost effective roofing solutions to house owners and businesses, TPO roofs are dirt, algae and bacteria resistant. The flexibility and durability of the membrane also makes it highly resistant to punctures, and wear and tear. A TPO roof can also withstand the damaging ultraviolet and chemical exposure without losing its efficiency. This is because hot air welded seams are 3 to 4 times greater in strength as compared to EPDM adhesive and tape seams.

TPO is also well designed to meet the increasing demand of green roofing materials. As an environment friendly solution, with solar reflective properties and a light color, TPO roofs result in lesser amounts of energy being wasted through HVAC systems. Being chlorine free, TPO is also one of the few roofing materials which can be recycled completely  to be used in the manufacturing process again.

PVC (Polyvinyl Chloride)

PVC is a relatively hard roofing material and possesses the benefits of plasticizers and contributes in making the membrane more flexible. PVC membranes are heat welded at the seams which create a durable monolithic structure.  They are also resistant to bacterial growth and plant root penetrations on the roof.

This vinyl roofing is however, less durable as compared to TPO and has a thicker membrane to maintain flexibility throughout its lifespan. PVC is usually formed with the help of other polymers and increases the performance capabilities of the original PVC formulation.

These roofs are energy efficient, mainly due to their light coloring. Additionally, vinyl membranes are used to provide waterproofing capabilities to the roofing.

Now that you know about both the types, after evaluating the benefits and qualities of both the materials, we recommend that you opt for TPO roofing due to its greater strength, durability and economical rates.
