PVC Roofing

Commercial PVC Roofing

PVC (Polyvinyl Chloride) is another widely used single-ply roofing membrane for commercial flat roofs. At a glance it looks similar to TPO, but it has different chemical properties and is often preferred in specific environments, especially where grease, oils, or chemicals are present (like restaurants, food processing, or certain industrial facilities).

Like TPO, PVC is installed in large sheets with heat-welded seams, creating a continuous, watertight system when installed correctly.

There are many PVC manufacturers, and several of the same companies that make TPO also produce PVC product lines. Both TPO and PVC typically come in different thickness options (e.g., 50, 60, 80 mil), with thicker membranes generally used for longer-term performance and warranty requirements.

At Llagua Roofing LLC, we work with major manufacturers and pursue the certifications required to install their systems according to specifications and qualify for available warranties. We can handle submittals, details, and coordination with reps and inspectors as needed.

PVC vs. TPO – Basic Comparison

Similarities:

    • Both are single-ply membranes
    • Both use heat-welded seams
    • Both are available in light colors for reflectivity
    • Both are offered by many of the same manufacturers

      Key Differences (in typical use):
      • PVC is often chosen where grease, oils, or certain chemicals may contact the roof
      • TPO is more common as a general-purpose, large-scale commercial membrane

(Actual performance depends on the specific product line, thickness, and installation quality.)

Pros of PVC Roofing

  • Heat-welded seams provide strong, continuous connections when properly installed
  • Often performs better than many materials in areas exposed to fats, oils, and some chemicals
  • Available in reflective colors that can support energy performance goals
  • Can be installed in various assemblies (mechanically attached, adhered, etc.)
  • Widely supported by established manufacturers

Cons of PVC Roofing

  • Typically more expensive than some TPO systems
  • As with TPO, performance depends heavily on installer skill and detail work
  • Can shrink or pull at terminations over time if not installed and detailed correctly
  • Punctures are possible in high-traffic areas without proper protection or walkway pads
  • Not every building needs PVC’s chemical resistance; in some cases, it may be more than what’s required

Is a PVC Roofing System the Right Choice for My Project?

When reviewing a commercial project, Llagua Roofing LLC can help compare TPO vs PVC based on the actual use of the building, rooftop conditions, and spec requirements, then install the selected system in line with manufacturer guidelines and code—no shortcuts, no guessing.
