Understanding the Differences Between TPO and PVC Roofing Systems

Without the proper understanding of the advantages and disadvantages of PVC and TPO roofing systems, one may invest their money in the wrong roofing system, which could lead them to have more costly expenses in the future. Even though the two mentioned roofing systems share the same membrane, there are still differences that you should know.

This article will tackle the differences between TPO and PVC roofing systems and other information you need to know about it.

The Difference Between the Composition of TPO and PVC

If you have seen the installation of TPO or PVC roofing, most of you will think that the materials used are the same. Even though they look quite identical, the two roofing systems have a unique composition.

PVC Roofing System – PVC stands for Polyvinyl Chloride that features a membrane made from 2 PCV plies with a polyester sheet between them. The following materials used to create PVC plies:

  • Biocides, which works to prevent the buildup of insects, rodents, algae, bacteria, and mold
  • Plasticizers, which works to improve the plies’ flexibility and plasticity
  • Polyester or fiberglass reinforcement
  • Color pigments
  • Ultraviolet light inhibitors

PVC roofing system maintains its water-tightness because of its hot-air welded seams. This means that it can withstand a wide variety of extreme weather conditions.

TPO or Thermoplastic Polyolefin Roofing System. Manufacturing the TPO membrane needs to combine two materials, which are the ethylene-propylene and polypropylene rubber. The TPO plies hold a polyester sheet between them, like the former roofing system. To form TPO plies, the following materials are needed:

  • Talc
  • Fiberglass
  • Color pigments
  • Ultraviolet light inhibitors

Considering the materials used to produce the TPO membrane, plasticizers are not the essential materials to improve its flexibility or plasticity. If it’s installed by a professional, it works in high-quality and can resist even severe conditions.

Performance Comparison Between TPO and PVC Roofing Systems

When it comes to wear and tear strengths, TPO outstands PVC. But, in terms of the overall cost, fire resistance, and chemical resistance, the PVC roofing system is listed on top. PVC is a recommended roofing system for buildings or restaurants with grease traps.

Both membranes of PVC and TPO roofing systems are excellent when it comes to their durability. Their thickness also impacts their pricing as well as their lifespan. Depending on your budget, experts recommend investing in the thickest membrane to avoid costly repair.

Pro Tip: Make sure not to depend on your budget when choosing the best roofing system. If you prefer TPO roofing systems to the PVC, make sure to ask and research reliable information about it. Despite your choice, make sure to hire a contractor with more than 20 years of experience in the industry. Also, work with a manufacturer that offers a clear warranty policy for their items.

Warranties Between TPO and PVC Roofing Systems

Before you check out your order, make sure that you know the product warranties. This is always true despite your choice. Whether you are choosing PVC or TPO, there are two types of warranties to keep in mind.

First, consider the warranty offered by the manufacturer. This type of warranty covers any defects or problems you notice on their roofing membrane in a specific period. The last one is the warranty of the roofing contractor, which includes his workmanship. When it comes to this warranty, you need to remember the items it covers as well as the actions to follow to prevent the warranty from being void.

Considering that the duration and coverage of the two warranties mentioned above will vary depending on the roofing system manufacturer as well as the contractor, this is usually a case-to-case basis.

Pro Tip: Before you agree to the warranty offered by the company and contractor, make sure to understand its coverage. Also, agree only if you’re satisfied with the warranty coverage. After completing the installation process, make sure to document all the warranty descriptions and certificates you can get from the manufacturer and contractor.

Overall Differences Between PVC and TPO Roofing Systems

Thermoplastic Polyolefin (TPO) is a roofing system that’s made from energy-efficient materials. Aside from that, it is also reflective of the sun’s UV rays. In terms of installation, TPO is way easier to complete compared to PVC. So, it’s recommended if you require immediate roofing. Also, this one lasts longer and is durable since it can resist mold growth.

On the other hand, in terms of Polyvinyl Chloride (PVC) is a popular roofing system among commercial business owners as it is more resistant to severe weather conditions. PVC roofing systems work better in flatter roofs and moderate climates. A plus point for it is that it does not require frequent maintenance. It is also an energy-efficient material, like a TPO roofing system.

Another notable difference between the two is their sheet flexibility. TPO has a more flexible sheet compared to PVC. You need to consider the sheet flexibility of the roofing system in terms of flash penetrations as it has something to do, especially in areas of the roof that are not watertight.

The good thing is that despite your choice, it can cut down AC bills because of the cooling effects it offers.


Roofing systems are popular for commercial properties, like restaurants and buildings. When it comes to roofing systems, PVC and TPO are the two popular roofing materials that need to be taken into consideration by most buyers.

To sum it up, both PVC and TPO roofing do their jobs. But, despite being similar in most cases, these two roofing systems are made from different materials. PVC is constructed from chlorine and ethylene, while TPO is constructed from polypropylene and propylene rubber. The two roofing systems look similar, but the PVC roofing system has been used since the 1960s, even until now, while the TPO roofing system started in the early 1990s.

Knowing the advantages and disadvantages of the two materials is important. This will help you to prevent impulsive buying decisions and further expenses in the future.

  3. During the winter season, the water piled-up is more likely to solidify and expand that can cause more damage.
  4. If the seams overlap, a large mass of water is prone to ponding that can cause damage to the membrane and its seal, allowing more water to pass underneath.
  5. If the stagnant water is not removed properly, it also creates moss, algae, and debris. Through these, a breeding ground for insects can produce.

How to Properly Slope a Flat Roof for Effective Drainage

How does a flat roof drains when they are flat? Have you ever asked this to yourself after admiring a flat-roofed house or building? Well, the answer to that is that although they are flat, they are not levelly flat. Simply put, they are slightly tilted in order for rainwater to drain. They only appear leveled to our eyes, but in actual and careful inspection, you will see that one edge is slightly higher than the other. So how do you properly slope a flat roof for drainage?

Proper Slope Height of a Flat Roof

If you are planning to have a rooftop garden, or if you simply want to maximize your space, a flat-roofed house is the best option for you. But bear in mind that roof drainage of a flat roof is more complex than a pitched roof. Experts in this field, however, find this as a challenge for them. Usually, their answer, if you ask them how to construct an effective drainage for a flat roof, is that all types of roof drainage will depend on how you slope your roof.

The correct tilt of a slope in your roof is the most necessary thing to do when constructing it. You have to remember that a failed slope on your flat roof is failed roof drainage. It should be noted that if you want a proper slop on a flat roof for drainage, you should tilt it with a correct height for the rainwater to flow naturally to the drainage system. Normally, an estimate of one centimeter (1cm) for every sixty centimeters (60cm) of width at the least should suffice for your slope to be described as correctly built. This will be successfully achieved if you use fir-rings in the construction of your flat roof drainage. Fir-rings are wood battens which have varying height in order to create a slight tilt on your flat roof. Once the slope is properly installed, your focus should now revert back to the flat roof drainage.

Common Types of Flat Roof Drainage

It is a must that flat roofs should have effective drainage in order to avoid pools of water to stock on it. Keep in mind that a pool of water stock on a roof will eventually lead to its damage and disintegration. To give you an idea of how a flat roof drainage works, here are the common types used by most.

Guttering Drainage

Guttering drainage is one of the most common types of flat roof drainage because aside from it being affordable, it is also effective. It is also called a conductor pipe. To describe it simply, it just like a trough positioned at the edge of your flat roof where water is mainly drained. Galvanized steel, vinyl, as well as aluminum are some of the materials commonly used for gutters.

Guttering drainage is also excellent in controlling the water flow from your flat roof. Because of its effective draining system, the foundations of your home will be well protected. Also, guttering drainage will not make you worry about soil erosion. The only downside in this flat roof drainage is that it easily clogs since it is an open drainage system. Thus, regular maintenance is required in order for increased longevity use.

Siphonic Roof Drainage

If you want your rainwater to flush itself from your flat roof, then your best choice is the Siphonic Roof Drainage. This flat roof drainage system will help the water pass to the drain faster than the other drainage types. This is generally constructed by allowing a minimal number of outlets, which are all connected and will drain in a single major pipe. Another note worth taking in this type of flat roof drainage is that it does not need sloped pipes. Hence, you will not have any problems when you have to install other equipment on your roof.

Inner Drainage

Inner drainage is most popular with commercial properties or buildings. In this type of flat roof drainage, pipes are placed underneath the roofs or in parapet walls in order to ensure that the pipes will not be visible and space will look good. This inner drainage system is usually positioned in the roof’s center or where the flat roof slope is directed downward.

This is one of the best choices if you are planning to construct a large roof or a rooftop garden since there are no visual hindrances present. A properly built slope plus a correctly installed inner drainage system makes a perfect combination. Another benefit of inner drainage is that even if there are leaks in the pipes, since the pipes are not in contact with the parapet walls or roof, there will be no damage to your property. The water will simply drain away. But on the downside, since the pipes are placed underneath the roof, its maintenance, as well as repair, is expensive as compared to other flat roof drainage systems. There is also a possibility of pipes being clogged. Thus, it is best to inspect them regularly.

Scuppers Drainage

In this type of flat roof drainage, opening at the sides of the walls are made where the water from the roof is carried to the gutter. Hence, when using this type of drainage, it is recommended to combine it with a guttering system. Also, in order to protect the walls from being damaged by the water, you also have to install collector heads aside from the gutters. One of the most recommended scuppers is the wide size so that it will not get easily clogged by leaves or twigs.

Another plus factor of this type of flat roof drainage is that even if there is debris, it will not block the water flow since you have the collector heads to do it for you. But of course, just like any other type of drainage, this also has its cons. One of its downsides is that if you have a limited space, you will have no choice but to use small scuppers. Unfortunately, unlike wide scuppers, small ones easily clog because of its size. Moreover, combining it with downspouts is not a good idea since it may affect the sturdiness of your home’s foundation.

These are only some of the drainage system that you may use for your flat roof. However, if you want to make sure that your home has a properly tilted slope and the best flat roof drainage, it is still recommended for you to consult and hire a professional.
