What is Single-Ply Roofing And Why You Should Switch To It

According to a 2021 survey by Roofing Contractor, an overwhelming 91% of their commercial respondents prefer single-ply roofing over other types of roofs.

For many roofing contractors, this statistic doesn’t come as a surprise. Over the past couple of years, companies and architects have opted for low-sloped roofs because of their many advantages. When it comes to low-sloped roofs, single-ply roofing systems are almost always the first choice.

In this article, we’ll talk about what makes single-ply roofing unique and why you should consider switching to it.

What Is Single-Ply Roofing?

Single-ply roofing systems are commonly referred to as single-ply membranes. This type of roof is made of sheets of rubber and various synthetic materials or chemicals. Singly-ply membranes are designed to be installed in one layer.

They are fastened, glued, or installed directly over a roof’s insulation to create a layer of protection. Many contractors prefer single-ply roofing on low-sloped roofs because they are easy to install over their current flat surfaces.  

Types of Single-Ply Roofing

Single-ply roofing has three major types, each with its unique capabilities. These three types are the following:

●   Polyvinyl Chloride (PVC): PVC is known for its longevity, durability, and chemical resistance. It can withstand large chemical build-ups and acidic outflows. PVC roofing is also very easy to manufacture, install, and repair.

●     Ethylene Propylene Diene Terpolymer (EPDM): This is a flexible and versatile type of single-ply membrane that can be installed quickly. It is resistant to UV radiation, extreme weather conditions, and thermal shocks. EPDM roofing is expected to last for over 30 years.

●     Thermoplastic Olefin (TPO): This is another common roofing material in commercial properties and buildings with flat roofs. It’s designed to reflect UV radiation, have excellent weather resistance, and be 3 to 4 times tougher than EPDM.   

Advantages of Single-Ply Roofing

Single-ply roofing has advantages that make it attractive to both contractors and property owners:

1. Easy to Install While Lasting a Long Time

Single-ply roofing is one of the easiest to install, especially on flat roofs. It can be installed in three ways: ballasted, using an adhesive, or mechanically fastened. Whatever you choose, the installation process is still far less complex than other systems.

Single-ply roofing is also known for its endurance. A properly installed and maintained single-ply roof can last between 20 and 50 years.

2. Flexible & Lightweight

Even with multiple layers, single-ply roofing is considered lightweight compared to other commercial roofing systems. A light roof relieves stress on your commercial building.

In terms of flexibility, contractors can use single-ply roofs on any roofing system, even the most complex designs. Single-ply roofs can stay intact even if the building is renovated or expanded. 

3. Extremely Durable

All types of single-ply roofing are durable. They can withstand tears, punctures, and blunt damage. They can also withstand extreme weather like strong winds and sudden temperature changes.

Single-ply roofing resists many kinds of chemical damage, too. It’s also fire retardant and has the unique ability of self-extinguishing.

There are many reasons single-ply membrane is the roofing system of choice for commercial property owners. With its unique features and capabilities, single-ply roofing is something you should consider if you’re installing a new roof.
