TPO Roofing Installation: What Commercial Property Owners Need to Know

August 14, 2025

When it comes to protecting your commercial property, few investments are as high-impact—and high-return—as your roof. And if you've been researching durable, energy-efficient options for flat or low-slope buildings, TPO roofing installation has likely risen to the top of your list.

At Best Roofing, we've seen firsthand how TPO (thermoplastic polyolefin) has become the go-to choice for South Florida businesses. But what makes this material so effective? And what should you expect during the installation process?

Let's break it all down—so you can make confident, cost-effective decisions for your building.


What Is TPO Roofing?

TPO is a single-ply roofing membrane made from a blend of polypropylene and ethylene-propylene rubber. It's known for being:

  • Highly reflective (ideal for sunny climates like Florida)

  • Resistant to UV, heat, and chemicals

  • Flexible, even in fluctuating temperatures

  • Cost-effective compared to other commercial roofing systems

This combination of performance and price makes TPO one of the fastest-growing commercial roofing products in the country.


Why TPO Roofing Is Ideal for Commercial Buildings

Whether you manage an office complex, retail center, or industrial facility, TPO offers key benefits tailored to business needs:

1. Energy Savings

TPO's white, reflective surface reduces heat absorption, lowering your HVAC load. Many clients report measurable energy savings, especially during South Florida's peak summer months.

2. Ease of Maintenance

Unlike multi-layered systems, TPO is seamless and simple to inspect. This makes it easier—and more affordable—to maintain over time.

3. Quick Installation

TPO membranes can be mechanically fastened, adhered, or self-adhered. Each method speeds up installation while maintaining performance, helping reduce disruption to your business operations.

4. Durability & Longevity

With proper installation and maintenance, a TPO roof can last 20+ years—a solid ROI for property owners focused on asset management.


The TPO Roofing Installation Process

At Best Roofing, we follow a proven process that combines precision, safety, and manufacturer-certified techniques. Here's what you can expect:

1. Roof Preparation

Before the membrane goes down, we assess and prep your existing substrate. This might involve:

  • Removing the old roofing system

  • Cleaning and leveling the deck

  • Ensuring proper drainage

Pro Tip: If moisture or ponding water is found during inspection, we address it upfront to prevent future problems.

2. Insulation Installation

We install high-performance insulation—most often polyisocyanurate (ISO)—which boosts your building's energy efficiency. Other options include EPS and XPS, depending on your needs and budget.

All insulation boards are custom-cut around penetrations (vents, HVAC units, etc.) for a tight, efficient fit.

3. Cover Board Placement

A high-density cover board is placed on top of the insulation. This:

  • Creates a solid surface for membrane adhesion

  • Improves wind uplift resistance

  • Adds fire and impact protection

4. Membrane Application

The TPO membrane is installed one roll at a time. We offer three options based on your building's conditions:

  • Mechanically fastened (with plates and screws)

  • Fully adhered (with bonding adhesive)

  • Self-adhered (pre-applied adhesive for faster installs)

Every seam is heat-welded using automated welders for a watertight seal. This is a crucial step that sets TPO apart from older glued systems.

5. Detailing & Flashing

To complete the system, we:

  • Flash around walls, curbs, drains, and penetrations

  • Reinforce vulnerable areas

  • Conduct a final inspection to ensure quality and compliance


Self-Adhered TPO: A Smarter Installation Option

One exciting innovation in TPO systems is self-adhered membranes. These pre-coated rolls come with built-in adhesive, eliminating the need for VOC-heavy bonding agents.

Benefits of Self-Adhered TPO:

  • Faster installs with fewer steps

  • Reduced labor costs

  • No flash-off time—work moves continuously

  • Environmentally safer (low-VOC, odorless application)

  • Clean, consistent adhesion

Self-adhered TPO is especially useful for buildings with sensitive tenants (like schools or medical facilities) where odor and disruption must be minimized.


Common Questions About TPO Roofing Installation

Q: How long does it take to install a TPO roof?
A: Installation time varies by project size and complexity, but many commercial roofs can be completed within 1-2 weeks. Self-adhered systems may reduce timelines even further.

Q: Can TPO be installed over my existing roof?
A: Sometimes. If the underlying structure is sound and local code allows it, a recover may be an option. We always conduct a detailed inspection before recommending this route.

Q: Is TPO better than PVC?
A: It depends on your priorities. TPO is affordable than PVC. It's a great all-around solution for South Florida's climate, especially when energy efficiency is a key goal.
