Are you in the market for a new roof for your business, warehouse, or factory in the Elkhart or South Bend area? There are so many roofing products out there, and commercial roofing requires special expertise.

Finding the right product and a contractor to install it can feel overwhelming. It can be hard to know where to begin.

Like many aspects of building infrastructure, your roof is probably something you don’t give much thought to, until it doesn’t work. Depending on the size and number of your buildings, commercial installation can be a daunting undertaking. But products like prefabricated Duro-Last roofing can make this process easier.

The information below details some reasons to consider Duro-Last for your commercial roofing needs. It may be the solution to you having a sturdy, secure roof so that you can focus on the more important aspects of your business. 

What Is Duro-Last Roofing?

Duro-Last roofing is a single-ply, prefabricated roofing system for commercial and industrial buildings. Although it can be installed on almost any building, it is often seen on low-slope or flat commercial roofs, including factories, warehouses, government buildings, and even schools.

Duro-last membranes are made up of polyvinyl chloride (PVC), a durable polymer. PVC is a common product that is used in a variety of building and construction applications.

It is a thermoplastic, which means it becomes soft when heated, and hardens when cooled. This makes it an ideal product for roofing since it combines malleability with durability.

Roofs are made of many different layers. The “performance” layer is the outer, exposed layer. It is the main surface that defends against the elements.

The “scrim” is the second layer, which provides support to the performance layer. It aids in puncture resistance and helps reinforce the roof from being pulled or torn apart by weather, animals, or debris. The bottom layer attaches the rest of the roof to your building’s structure.

Duro-last membranes are available in 40, 50, and 60 mil thickness. And, with a 50-plus mil membrane, a 28-mil outer performance layer of PVC can be installed. This is far thicker than most industry standards.

Duro-last scrim layers are anti-wicking and have dense weaving––18 by 14 threads per inch––also among the highest in the industry.

What Are the Advantages of Duro-Last Roofing?

There are many reasons to consider Duro-Last products for your commercial roofing needs. The main ones are durability and prefabrication, although there are a few other attributes.


Duro-Last roofing material is extremely strong. Unlike many metals or other materials, PVC is long-lasting and resistant to corrosion and decay. It holds up to usual wear and tear, as well as severe weather events. PVC can withstand snow, ice, wind, and heat from the sun. It can even endure some fires.

Despite being durable, PVC is very lightweight. This aids in the construction and transportation of the roofing system. It also makes it easier to install, which can save a lot of time and money. This also enables greater thickness in layering that protects against damage.

Finally, being lightweight creates the option of installing a Duro-Last roof on top of an existing one. This also can save a lot of money since you avoid the labor of tearing off and disposing of the old roof.


Duro-Last offers prefabrication of the entire roofing system. There are many advantages to this, including that your roof is constructed in a controlled climate, as opposed to a rooftop where the environment is unpredictable. This also reduces rooftop labor, which makes installation easier, quicker, and less disruptive to your business.

In most roofs, water penetration is common in seams that hold the roofing membrane together. Since upwards of 85 percent of the Duro-Last roofing seams are completed in a factory-controlled environment, prefabrication minimizes the chance of leaks. And single-ply is a wide-width sheeting that has far fewer seams in general than most standard asphalt roofs.

Prefabrication also allows for the complete customization of your roof. Your contractor will have the ability to plan every detail of your roof accessories at the outset. This includes the placement of drains, curbs, stacks, vents, and corners.

Although regular inspection and upkeep will increase the longevity of any roof, Duro-Last roofing is very low maintenance. Routine inspection can check for potential damage, but once the roof is secured in place, there is very little to maintain.

Other Attributes

Duro-Last roofing is energy-efficient, due largely to its reflexivity. They are ENERGY STAR certified and can yield huge energy cost savings.

Although white offers the most UV reflexive power, Duro-Last membranes are available in five different colors. These include shades of gray, white, and brown.

Also, the components that make up PVC also are widely available. This helps makes Dura-Last products more economical than many other alternatives.

Finally, Dura-Last is a company that has been around since 1978. They are the world’s largest manufacturer of prefabricated roofing systems, with billions of square feet of membrane installed worldwide.

Although most reputable contractors will offer a guarantee with your service, Duro-Last offers its own 15-year manufacturer’s warranty. They even cover consequential damage to commercial roofing.
