At Riddell Roofing, we work extensively with PVC roofing materials. There are many reasons why Duro-Last’s PVC roofs are known as the best, but what are your other options?

Besides PVC, you have two main other options for flat roofing. The most popular alternatives are TPO and EPDM, both of which are rubber roofing. There are pros and cons to each, and it’s important to understand the ins and outs of each material before committing.

PVC

When it comes to durability, PVC membranes can’t be beat. Known formally as Polyvinyl Chloride, it’s hard plastic material that can withstand a lot of pressure, be it from heavy use, or the forces of nature. That’s why it is one of the most popular roofing materials on the market.

Another advantage of PVC roofing membrane is prefabrication. With companies like Duro-Last, your building is measured and the roof is constructed off site. This means the resulting roof has stronger seams and a more precise fit.

The only drawback of PVC roofing is the price. While it is generally more expensive than TPO and EPDM, not only will your roof last longer, but it is usually covered under a lifetime warranty.

In addition, while there may be a higher material cost, prefabrication makes for less installation time. That means lower labor costs, and less interruption of business.

TPO

TPO, or thermoplastic polyolefin, is one of the most widely used roofing materials in the industry. The main drawing point is simply price. It’s a very affordable material, but that should not be the only factor in your decision.

While the price point may be enticing, there are some major durability and longevity concerns. TPO is a newer product, and its track record is not amazing. While the seams offer similar durability to PVC, it has a tendency to shrink over times. This leaves gaps at curves, making for instability and potential leaks.

If budget is the only concern, TPO is a viable option. However, when you take repairs and potential energy lost through gaps, the value goes down, and your costs go up.

EPDM

Ethylene Propylene Diene Monomer is the last material. While EPDM is very popular, it mostly comes down, once again, to cost. It’s much cheaper than PVC, and it has a longer, more successful track record than TPO.

However, it’s simply not as strong. Except in cases where TPO has failed and experienced shrinkage, the seams and overall durability falls short of both TPO and PVC.

In addition, EPDM has been shown to increase utility bills. As it is mostly available in black, it absorbs heat. During the summer, this could lead to high cooling costs. With that in mind, the low material price isn’t quite the drawing point it originally seems to be.

You have many choices when it comes to roofing materials. However, PVC has the stats and track record that you can trust. With the expertise of Riddell Roofing, and the superior quality of Duro-Last, you’ll have a roof you can rely on for years to come. Call us today to schedule a free consultation.
