The Pros and Cons of Duro Last vs. TPO Roofing

In Arizona, you have a lot of great options for roofing, but you also have a lot of unique challenges to overcome. The harsh climate means that you need roofing that can withstand temperature extremes (including excessive heat), intense rainstorms, and strong winds. Not all roofing types can handle those conditions, which means you’ll be looking at frequently repairing your roof or replacing it early.

Two roofing types – Duro Last and TPO – are very popular in Arizona from the company of, because they stand up to these elements and last a long time. But these two roofing types aren’t created the same. Take a look at the pros and cons and then talk to a roofing contractor n Arizona about which would be best for your property:


Duro-Last Roofing

Duro-last roofing looks like a sheet of PVC. However, it is composed of two layers of thermoplastic created with a mix of plasticizers, stabilizers, flame retardants, resins, and biocides. There are also materials in it that absorb UV rays. The two layers of thermoplastic sandwich a knitted scrim, making the roofing durable and long-lasting.

Duro-last roofing in Arizona comes in a wide variety of colors, so you can create the aesthetic that you want for your property.


TPO stands for thermoplastic polyolefin. You might think that it is similar to Duro-last because of its name, but TPO is not a plastic roofing type. It is made of rubber composed of ethylene-propylene and polypropylene.

TPO is single-ply, while Duro-last is multi-ply. That means that TPO is not as durable as Duro-last. However, the reduced number of layers makes TPO lightweight, which makes it easier to install.

The Pros

There are a number of pros to using either Duro-last or TPO roofing.

Duro-last is prefabricated.

A commercial roofing contractor states that your roofing contractor will come to your home or business and measure your roof. Your roofer will then order the materials already cut to the specifications of your roof. That means that there will be fewer seams, which can allow moisture to penetrate the roof. Prefabrication also reduces the installation time, which will reduce the overall cost of the roofing. Remember, its important to find a reliable roofing company.

TPO roofing is not prefabricated. Instead, it is welded. Though it may end up being water-proof, it is not as durable as Duro-last, and it will cost more to install.

Duro-last is easy to install.

Yes, it is easy to install because it is prefabricated, but it is also easy to install because it can be applied directly to your old roof. Your roofing contractor does not have to rip up the old material, which reduces waste and saves you money. The installation won’t even be noisy or smelly.

Duro-last is energy efficient.

After the installation of your roof, the energy that your property consumes is probably your biggest expense when it comes to your roof. You may not think of it, but your roof contributes significantly to how much energy your property consumes. Duro-last is one of the most energy-efficient roofing materials, and it will keep your costs low.

TPO roofing is also energy-efficient since it has a reflective, white surface, but it is not nearly as energy-efficient as Duro-last.

Arizona’s Duro-last has the best warranty. You can buy a warranty that gives you protection for over 20 years. Your roofing company may give you a warranty on their work, but most roofing materials don’t come with a warranty like Duro-last’s. That warranty takes care of the roof, but what about the other aspects of the house? a home warranty for you that’d cover the major costs that the house incurs is the best kind of comprehensive warranty. 


Of course, there are a couple of cons, depending on your perspective.

One of the biggest disadvantages of these two roofing types is that TPO roofing isn’t as durable as Duro-last.
The welded installation may provide protection against water damage, but over time, those seams can start to crack and allow damage to grow. Other parts of the roof can also crack or shrink over time, leaving the roof vulnerable.

Duro-last offers seamless protection and is durable over the long term.

Both Duro-last and TPO have qualities to recommend them, but if you want the best protection for your investment, Duro-last is the better option for your property.
