How a TPO Roof Is Built

TPO stands for thermoplastic polyolefin. It comes in wide rolls that are laid over insulation or a cover board and then welded at the seams with hot air, forming one continuous waterproof sheet.

The white surface reflects sunlight, which matters on a hot-climate roof. We install new TPO systems, repair existing ones and detail the flashing at walls, drains and rooftop equipment.

Why Buildings Choose TPO

  • Reflective surface

    A white membrane sends sunlight back instead of soaking it into the building.

  • Welded seams

    Heat-welded seams, done well, form a strong waterproof bond.

  • Efficient on big roofs

    Wide sheets cover large flat areas quickly with fewer penetrations to detail.

TPO for Downtown Buildings

Large flat roofs on offices, retail buildings, hotels and multi-family properties are a natural home for single-ply membranes. Old Town has plenty of them, from buildings near the Civic Center, which spans 21 acres, to commercial blocks along Fifth Avenue.

The trickiest part is rarely the open field of the roof. It is the details: parapet walls, drain bowls, pipes and rooftop equipment. Our crews spend their effort there, because that is where leaks start.

TPO Installation Steps

A TPO project moves through clear stages:

  • Inspect the existing roof and decide between full tear-off and recover.
  • Install or repair insulation and a cover board where required.
  • Attach the membrane mechanically or with adhesive, according to the design.
  • Weld the seams with hot air and probe them to confirm they are sealed.
  • Flash walls, drains and penetrations with prefabricated boots and welded details.

TPO Compared With Other Flat Systems

TPO is not the only choice. Spray foam suits irregular shapes and adds insulation, and a coating can protect a roof that is still in good condition. TPO usually fits best on large, simple roofs with a sound deck where a clean sheet system saves labor.

We compare the options for your building and explain the trade-offs. See foam roofing or roof coatings if you would like to read about those routes first.

Caring for a TPO Roof

TPO is low-maintenance, though not maintenance-free. The usual upkeep includes keeping drains clear, washing the surface when it gets dirty so it stays reflective, and checking seams and flashing on a regular schedule.

Foot traffic from equipment technicians is the most common cause of punctures. Walkway pads and clear access routes cut that risk.

Typical TPO Repairs

Small punctures and splits are patched with compatible TPO and welded in place. Failed flashing at walls and curbs is cut out and rebuilt with new membrane. When seams have opened over a wide area, we assess whether the roof can be repaired or whether the membrane has reached the end of its life.

Questions to Ask Before Choosing TPO

These questions help confirm that a single-ply membrane is the right fit:

  • Is the existing roof dry, and is the deck in good condition?
  • How many penetrations, drains and equipment curbs must be detailed?
  • Will foot traffic from equipment technicians be frequent?
  • Does the building need more insulation at the same time?
  • What warranty comes with the membrane and the installation?

Insulation and Energy Considerations

A TPO roof is often installed over rigid insulation, which is where much of the building's thermal performance comes from. The white membrane keeps the surface cooler, and the insulation slows heat moving through the deck.

If the existing insulation is wet or crushed, we recommend replacing it during the project instead of covering a problem with a new sheet.

TPO Roofing FAQs

Can TPO go over existing roofing?

Sometimes, depending on the existing roof and local code. We inspect first.

Are TPO seams reliable?

Welded seams are strong when done properly, which is why installer skill matters.

Is TPO used on homes?

Mostly on flat commercial and multi-family roofs, and sometimes on flat residential sections.

How are penetrations handled?

With prefabricated boots and welded flashing.

Does TPO need maintenance?

Periodic inspections catch seam and flashing problems early, and cleaning keeps the surface reflective.

Can an existing TPO roof be repaired?

Yes. Small splits and failed flashing are commonly repaired with compatible patches and welds.
