What is TPO Roofing?
TPO stands for Thermoplastic Polyolefin, a single-ply membrane roofing made from a blend of rubber and include synthetic materials. It’s slightly new in the industry and primarily used on flat or low-slope roofs, offering a durable, energy-efficient, and cost-effective alternative to older roofing systems like EPDM or built-up roofs.
If you’re a customer researching the market for modern residential and commercial roofing solutions, you’ve likely come across TPO roofing. But what is TPO roofing material exactly, and why is it becoming so popular among commercial and residential property owners?
In this guide, we’ll break down everything you need to know — from what TPO is, to its pros, cons, costs, and how it is benefitial and compares to other flat roofing options.
TPO single-ply roofing membrane is generally installed in large rolls and typically, is heat-welded at the seams to create a cooler watertight surface layer.
Key Advantages and TPO Roofing Benefits
✅ Energy Efficiency – TPO membranes are helping reduce sunlight in Summer and energy savings on cooling costs by reflecting UV rays.
✅ Durability – Resists punctures, tears, and dirt buildup better than many other flat roof materials.
✅ Affordable – Lower material and installation costs compared to PVC roofing.
✅ Flexible – TPO can handle building movement, insulation and thermal expansion without cracking.
✅ Eco-Friendly – 100% recyclable and often meets ENERGY STAR® and LEED requirements.
Some of the Disadvantages of TPO Roofing
❌ Shorter Track Record – TPO roofing is relatively new compared to EPDM or PVC, so performance is still being evaluated.
❌ Inconsistent Quality Across Brands – Some manufacturers produce lower-quality TPO membranes, making it crucial to choose a trusted brand.
❌ Vulnerable to When Stressed – While durable, TPO can still be damaged by sharp edge objects or heavy foot traffic on commercial roofs.
❌ Heat-Welded Seams Require Skilled Installers – Proper installation is critical; poorly welded seams can cause leaks or insulate issues and system failure.
❌ Limited Chemical Resistance – TPO doesn’t perform well when exposed to grease, oil, or harsh chemicals, making it less ideal for certain industrial and commercial facilities.

TPO Thickness Options
TPO comes in multiple thicknesses:
-
45 mil – Budget-friendly, but thinner and less durable
-
60 mil – Most common, great balance of price and performance

Consider TPO if you want:
-
A cost-effective solution
