What Is TPO Roofing?
TPO roofing material (Thermoplastic Polyolefin) is a single-ply membrane system commonly used on low-slope commercial roofs. In simple terms: it’s a flexible, high-performance sheet membrane designed to resist UV exposure, weathering, and punctures—while remaining lightweight and efficient to install.
A professionally installed TPO roof typically includes:
TPO membrane (the primary waterproofing layer)
Insulation (to improve thermal performance)
Cover board (optional, improves durability)
Adhesives/fasteners and heat-welded seams
Flashings and details around penetrations, edges, and drains
TPO Roofing Services We Provide
North American Roofing provides full lifecycle TPO roofing support for commercial buildings:
TPO Roof Replacement
When a roof has reached the end of its service life, we can remove and replace the system or recommend a more suitable option based on your facility’s needs.
TPO Roof Repair
Many leaks don’t require a full replacement—especially when a TPO roof is still in good overall condition. Our team can diagnose and repair common problems like seam issues, flashing failures, punctures, and drainage-related leaks.
TPO Roof Installation
If you’re installing a new low-slope roofing system, we’ll evaluate the deck, insulation requirements, drainage conditions, and building use to spec the correct TPO roofing material and installation method.
TPO Roofing Material: Installation Methods
TPO roofing systems can be mechanically attached, fully adhered, or ballasted. Heat-welded seam technology creates an impermeable, monolithic TPO membrane seam for maximum strength and leak prevention for your industrial roofing or commercial roofing protection. Large TPO roof sheets, available in widths up to 12 feet, allow for faster installation so you can get back to focusing on your business.
The right installation method depends on your building design, wind requirements, budget, and performance goals. TPO roofing can be installed using several approaches:
Mechanically Attached TPO Roof
The TPO roofing material is secured using fasteners and plates, then seams are heat-welded. This method is common for many commercial applications and can be a cost-effective solution.
Fully Adhered TPO Roof
The membrane is adhered directly to the substrate with approved adhesives. A fully adhered TPO roof can offer excellent uplift resistance and a smooth finished look.
Ballasted TPO Roof
In certain configurations, the membrane is held in place using ballast such as stone or pavers. Ballasted systems are not appropriate for every building, and we evaluate structural and wind considerations before recommending this method.
Advantages of TPO Roofing
A well-designed TPO roof can be a strong long-term investment for many commercial facilities. Benefits often include:
Reflective surface: Many TPO roofing material options support energy efficiency goals by reflecting sunlight and reducing heat gain.
Heat-welded seams: Welded seams create a strong, watertight bond.
Durability: Good resistance to UV, weathering, and many rooftop stressors.
Versatility: Works for new builds and many replacement scenarios.
Proven commercial performance: Widely used across warehouses, retail centers, manufacturing buildings, and more.
TPO roofing membranes are a heat-weldable blend of polypropylene and ethylene propylene rubber components, available in white, gray, and tan, with white being the most popular for its high reflectivity. A TPO roof can be installed in a variety of thicknesses and price options, ranging from 45 mil to 80+ mil, making it suitable for a wide range of commercial roofing facility applications and budgets. These systems offer proven performance for replacing or recovering existing roofs. Their UV-resistant properties reflect nearly 87 percent of harsh sunrays away from the surface, significantly reducing cooling costs in air-conditioned facilities. A quality TPO membrane also delivers excellent wind uplift resistance and typically comes with warranties of up to 25 years.
Is a TPO Roof Right for Your Building?
TPO roofing is often a great fit for low-slope commercial buildings, especially where efficiency, seam performance, and lifecycle value matter. That said, every facility is different.
We’ll consider:
Roof slope and drainage
Existing roof condition (repair vs recover vs replace)
Wind uplift requirements
Penetrations, curbs, edge metal, and detailing complexity
Building use and access needs
If TPO roofing material isn’t the best match, we’ll tell you—then recommend a better system for your application.

FAQs About TPO Roofing
How long does a TPO roof last?
A TPO roof lifespan depends on membrane thickness, installation quality, details, and maintenance. Many commercial systems are designed for long service life when properly installed and maintained.
Can a TPO roof be repaired?
Yes. Many TPO roofing issues are fixable—especially seam problems, flashing failures, punctures, and localized damage.
Can TPO roofing material go over an existing roof?
Sometimes. A TPO roof recover may be possible if the existing roof is structurally sound and not moisture-saturated, and if code requirements allow it.
What causes TPO roof leaks?
Common causes include seam separation, flashing/detail defects, punctures from foot traffic, poor drainage, and aged or improperly installed roof accessories.
What’s the difference between mechanically attached and fully adhered TPO roofing?
Mechanically attached TPO roofing uses fasteners and plates; fully adhered uses adhesives. The best choice depends on wind design, substrate, budget, and building requirements.
TPO Roofing Systems Offer Flexibility, Versatility, and High Performance.
TPO roofing is the fastest-growing commercial membrane roofing system and a leader in single-ply technology. Engineered for superior, long-term performance, it also offers the advantage of being environmentally sound. Installers and property owners alike value its advanced reflectivity, which pairs well with cool roof solutions to help reduce energy costs in storage facilities, warehouses, and work environments. This TPO membrane requires minimal maintenance and delivers impressive versatility, resisting environmental pollutants and chemicals. In storm-prone regions, a durable TPO roof offers abrasion, tear, and puncture resistance for added protection. It can even contribute to LEED credit qualification and is recognized by both Energy Star and the Cool Roof Rating Council.
