TPO Roofs
TPO, short for thermoplastic polyolefin, is a single-ply roofing membrane that has become one of the most common choices for new low-slope roofs. Its two defining traits are a reflective white surface and seams that are melted together with hot air rather than glued.

What makes TPO different
TPO is a thermoplastic, which means it softens with heat and can be welded. Where two sheets overlap, a hot-air welder fuses them into a single piece, and a properly welded seam is typically as strong as the sheet around it. Compared with EPDM, whose seams rely on tape and adhesive, that welded seam is TPO's main advantage. Compared with PVC, which is welded the same way, TPO usually costs less but is not as resistant to oils and grease.
A reflective surface
Most TPO is white or light gray. A white roof reflects much of the summer sun that a dark roof absorbs, which keeps the membrane cooler, reduces heat in the space below and can lower cooling costs on buildings with a large roof area. That matters most on commercial buildings, rowhomes and additions where the roof sits directly over living or working space.
How TPO is installed
TPO goes over a layer of rigid insulation or a cover board. It is either mechanically fastened, with plates and screws along the seams that the next sheet covers, or fully adhered with bonding adhesive. Every seam is welded and then probed to check for gaps. Walls, curbs and pipes get welded TPO flashing, and the roof edge gets metal that the membrane is sealed to, so water flows cleanly into the gutters or scuppers.
Keeping a TPO roof healthy
A TPO roof needs little, but not nothing. Clear debris from drains, scuppers and gutter edges so water does not back up. Keep foot traffic to walkway pads where possible, since tools and dropped screws can puncture the sheet. After a storm or contractor work on rooftop equipment, look for cuts, loose flashing and seams that have opened. Small punctures can be patched by welding on a new piece of TPO.

Process
How long does a TPO roof last?
A well-installed TPO roof often lasts 20 to 30 years. Drainage, seam quality and how much traffic the roof sees matter more than the calendar.
Is TPO or EPDM better for my roof?
TPO has welded seams and a reflective surface. EPDM is very flexible in cold weather and simple to patch. For a large sunny commercial roof TPO is often the pick, while EPDM remains a solid choice on many small residential sections.
Can TPO be repaired?
Yes. A clean, dry TPO roof can have patches welded on, and opened seams can be rewelded. Very old, chalky TPO is harder to weld and may be better covered with a new membrane or replaced.
