Have you heard about single ply roofing? Perhaps you have, and are considering single ply roofing for your home - but you aren’t aware of the basics.
Simply put, single ply roofing is a lightweight, flexible type of flat roof covering. Like the name suggests, this roofing system is composed of one layer or “ply.” The materials used for single ply roofing resemble vinyl.
If you have questions about single ply roofing, Tarheel Roofing and Construction has straightforward, beginner-friendly answers. Read on to find out the answers to the top five most commonly asked questions about single ply roofing.
What is a single ply roofing membrane made of?
A single ply roofing membrane is made up of flexible sheets of synthetic polymer. These polymers are categorized as either thermoplastics or synthetic rubber. Thermoplastics are the more popular choice for roof installation due to its ability to be reheated and remolded.
What are the materials used in single ply roofing?
Tarheel Roofing and Construction specializes in TPO, PVC, and EPDM single ply materials.
Thermoplastic Polyolefin, or TPO, is one of the most common types of membranes used on flat roofs. TPO feels like rubber and typically comes in white.
Polyvinyl Chloride, or PVC, has been a staple in the roofing industry since the 1960s. Found in an array of colors, PVC is particularly adaptable thermoplastic, as it can cover a range of surface sizes. Read more about the uses, benefits, and safety information about PVC here.
EPDM stands for Ethylene, Propylene, and Diene Monomer. The acronym comes from the mix of materials used in this type of single ply roofing membrane. Colors vary from black to gray. Its smooth feel comes from its absence of surface granules.
Also keep in mind the difference in thickness for each material. EPDM is the thinnest material - usually less than a mm in thickness - whereas PVC is the thickest.

What are the benefits of single ply roofing?
No matter your home, single ply roofing comes with multiple benefits, such as:
Weather Resistance - This is a must-have for any roof, but with the application of a hot air wield, a single ply roofing system helps protect against extreme weather and temperatures.
Chemical Resistance - Single ply roofing is resistant to potentially harmful chemicals, such as acidic outflow (acid rain). Most materials are immune to the build up of microorganisms as well.
UV Resistance - Ultraviolet light from the sun can damage roofing, so it’s imperative for any roofing material to be UV resistant. Fortunately, most single ply membrane materials are 100% resistant to harmful UV rays.
Fireproof - Not only are singly ply roofing membranes fire resistant, but they’re also self extinguishing! Stores, offices, and corporate buildings can now ensure the safety of their employees and visitors in case of a fire.
Good for the environment - Compared to traditional roofing options, single ply roofing is much better for the environment. This is due to their production, longevity, and most of all, recyclability.
What are the downsides to single ply roofing and suggested alternatives?
A notable downside is that single ply roofing membranes can be punctured more easily compared to other roofing types. Damage to the membrane may cause leaks.
In addition, roof penetrations such as pipes, HVAC systems, or chimneys, may make the project more expensive. The simpler the roof, the simpler single ply roofing system can be installed.
Downsides to single ply roofing also depend on material type. For instance, PVC is great at resisting heat, but may not bode well in places with lots of rain and snow.
Some alternatives include metal roofing, slate roofing, shingles, or solar tile. It all depends on what benefits matter most for you and your home.
How is single ply roofing installed?
Fortunately, single ply roofing membranes are easy to install. However, installation varies by material.
Standard methods include full adhesion, mechanical attachment, or ballasting. Then, the seams are glued or taped. A nail gun may be used as well.
