The flat roof over your building, or over the addition on the back of your house, needs replacing. One roofer recommended TPO, another said EPDM, and a third quoted something you’d never heard of. If you’re reading up on TPO roofing in Kansas City, you’re probably trying to figure out whether the white roof everyone’s talking about is right for you, or just the popular choice this year.

That confusion is common, and it’s not your fault. Flat roofing comes with a lot of acronyms, and a roof you rarely see is a hard thing to judge. You deserve someone who explains the trade-offs in plain words and then lets you decide.

APC Roofing installs and repairs TPO roofs on homes and light commercial buildings across the Kansas City metro, on both sides of the state line. We’re a GAF Certified contractor, licensed and insured, in business since 2017, and your inspection and estimate are free.

What TPO is

TPO stands for thermoplastic polyolefin. It’s a single-ply roofing membrane, usually white, with a fabric reinforcement sandwiched inside for strength. It comes in rolls, and the sheets are joined by melting the edges together with a hot-air welder. Once a seam cools, the two sheets have become one piece.

That welded seam is TPO’s biggest advantage. Seams are where flat roofs leak most, and a properly welded TPO seam is often stronger than the membrane around it. It’s also why the installer’s skill matters so much. A seam that’s welded too cool or too fast can look fine and still let go later, so good crews check every seam after welding.

TPO comes in different thicknesses. Thicker membrane costs more and stands up better to foot traffic, hail and years of sun.

How TPO roofing in Kansas City handles our weather

Summer heat. A white TPO roof reflects much of the sun’s heat instead of soaking it up. On a building that runs the air conditioning hard from June through September, or a bedroom under a flat roof that’s always too warm, that can make a noticeable difference.

Hail. TPO holds up reasonably well to hail, especially in thicker grades over a firm cover board. Large hail can still bruise the insulation underneath or puncture an older membrane, so after a big storm it’s worth having it checked even if nothing leaks.

Cold. TPO gets stiffer in the cold, which matters more during installation than after. Some adhesives need warmer temperatures to bond, so winter jobs may call for different products or a different day.

Ponding. Water that sits on any flat roof works on the seams and freezes in winter. TPO handles occasional ponding, but the better fix is building slope into the roof so water drains.

TPO vs. EPDM

Both are good roofs, and both are common around Kansas City. TPO is white, reflective and has heat-welded seams. EPDM is black rubber that stays flexible in the cold and comes in wide sheets with fewer seams, joined with tape and adhesive. If summer heat is your bigger worry, TPO usually has the edge. If the roof sees a lot of cold-weather movement or is a small, simple shape, EPDM is often a good fit. Our EPDM roofing in Kansas City page covers the rubber side.

Where TPO fits

On homes, TPO is a strong choice for porches, garages, additions and sunrooms with low-slope roofs, especially where the room underneath gets hot. On commercial buildings, it’s one of the most common membranes on offices, retail and warehouses. For full commercial projects, see our commercial roofing in Kansas City page.

How a TPO roof goes on

A new TPO roof starts with removing the old roof and checking the deck, replacing any soft or rotted wood. Insulation goes down next, often with tapered boards to add slope, then a cover board for a firm, smooth surface. The membrane is then attached in one of a few ways: fastened through the seams into the deck, fully glued down, or held by plates that are welded to the underside of the membrane. Seams are welded and checked, and the membrane is run up walls and around pipes and curbs with TPO flashing. Edge metal finishes the perimeter.

Repairing an existing TPO roof

Most TPO problems are repairable: an open seam, a puncture from a dropped tool or flashing that’s pulled loose at a wall. The area is cleaned and a new piece of TPO is welded over it. Older TPO that’s been weathered for years can be harder to weld, so it needs careful cleaning and prep first.

When the membrane is cracking across the field, seams are failing in many places, or the insulation underneath is wet, a TPO roof replacement usually costs less over time than repeated repairs.

TPO roofing questions

Is TPO a good choice for Kansas City winters?

Yes, when it’s installed right. Cold mainly affects installation, so timing and the right adhesives matter. Once in place, a well-welded TPO roof handles freeze-thaw cycles well.

Can you put TPO on a house?

Yes. It’s common on low-slope porches, garages and additions. It isn’t meant for steep roofs, where shingles or metal are the better fit.

Can you repair my old TPO roof?

Often, yes. Seams and punctures can be patched by welding new TPO over them, as long as the existing membrane is in decent shape.

Do you install TPO in Overland Park and Independence?

Yes. We work across the Kansas City metro on both the Kansas and Missouri sides.
