Single ply roofing is a lightweight roofing system made from one layer of flexible plastic or rubber material. It’s popular for commercial and flat-roof buildings because it’s easy to install and affordable. Single ply comes in three main types: TPO, EPDM, and PVC. Each type has different costs and durability. Many contractors choose single ply because it lasts decades and holds up well in tough weather.
What Are the Main Types of Single Ply?
According to industry data, 91% of commercial roofers use single-ply roofing systems. The three most common types are TPO, EPDM, and PVC. TPO makes up 38% of single-ply installations, EPDM covers 30%, and PVC accounts for 18%.
TPO is the most popular choice. It resists UV rays and heat well. EPDM is a rubber material that’s been used for decades. PVC is the strongest type and works great in places with chemicals or high traffic.

How Much Does Single Ply Roofing Cost?
Single ply roofing costs between $5.50 and $7.50 per square foot when installed. For a typical 1,700 square foot roof, you can expect to pay $6,800 to $68,000 total, depending on labor and materials. Flat roofing systems like single ply tend to be less expensive than shingles or metal options.
According to RubyHome, the average roof replacement cost is $9,526. Single ply is on the lower end of that price range.
How Long Does Single Ply Last?
Single ply roofing lasts 20 to 50 years on average. EPDM rubber roofs can last up to 50 years. TPO typically lasts 20 to 30 years. PVC often reaches 30 years or more.
This is much longer than asphalt shingles, which last only 20 to 30 years. Single ply requires less maintenance than many other roof types.
Why Choose Single Ply?
Single ply roofing offers many benefits:
- Easy and fast to install
- Lightweight on buildings
- Resists UV damage
- Good for flat roofs

According to the U.S. roofing contractor industry data, single-ply systems are the dominant choice in commercial roofing because they work well on flat surfaces and last many years.
