TPO

TPO Roofing

TPO (Thermoplastic Polyolefin) has become the go-to flat roof system on many commercial new construction projects. It’s a single-ply membrane that is heat-welded at the seams, lightweight, and often installed in a white or light color to help with energy performance.

There are many TPO manufacturers in the market, and membranes are available in different thicknesses (commonly 45, 60, or 80 mil), depending on the service life and warranty requirements the architect, builder, or owner wants to achieve.

At Llagua Roofing LLC, we are certified with several major TPO manufacturers. We can:

  • Provide project material submittals (data sheets, assembly details, warranty info)

  • Install systems in line with manufacturer requirements for warranty eligibility

  • Coordinate with reps and inspectors to help secure NDL (No Dollar Limit) warranties when required by spec

Our goal is a clean, compliant install that matches the design and performs as intended in real conditions.

Pros of TPO Roofing

  1. Widely used and understood in commercial construction
  2. Heat-welded seams provide strong, continuous connections when done correctly
  3. Light-colored membranes can help reduce heat gain and may support energy goals
  4. Works with multiple assembly types (mechanically attached, adhered, or ballasted)
  5. Relatively lightweight compared to multi-ply systems

Cons of TPO Roofing

  1. Performance depends heavily on membrane quality and installer skill
  2. Seams and details must be welded and checked properly; poor welding = weak points
  3. Can be more sensitive to chemicals, grease, and some solvents, especially near restaurants or mechanical areas
  4. Punctures can occur in high-traffic areas if no protection or walkway pads are used
  5. Edge, penetration, and termination details must be done right or they become failure points
