TPO Roofing in Greenville, SC
A bright, heat-welded single-ply membrane for large commercial and industrial roofs. It reflects the Carolina sun, installs efficiently over big areas and stays watertight at the seams.
Why TPO leads commercial roofing
TPO has become the most common choice for new and replacement low-slope roofs because it balances performance and cost on large roofs. Its white surface reflects much of the sun's heat, which helps reduce cooling load in hot, humid Upstate summers. Its seams are welded with hot air rather than glued, so the laps become part of the membrane.
What we do with TPO
- New construction: complete assemblies with insulation, cover board, membrane, flashings and edge metal.
- Tear-off replacement: remove failed roofing down to the deck, correct wet insulation and deck damage, and install a new system.
- Recover: where code and a moisture survey allow, install a new TPO system over the existing roof.
- Repairs: heat-welded patches, re-flashing curbs and penetrations, and seam repairs.
Details that decide how long it lasts
Most single-ply failures start at details, not in the field of the roof: curbs, pipe penetrations, wall transitions and perimeter edges. OTC fabricates its own sheet metal, so coping, edge metal and counterflashing are built to fit the job instead of forced to fit.
TPO or PVC?
If the roof sees grease, oils or chemical exhaust, from restaurants, food processing or some manufacturing, PVC is usually the better choice. For most warehouses, offices and retail buildings, TPO is the efficient default. Compare PVC roofing.
The seam is the system.
TPO and PVC sheets are joined with hot air, fusing the overlapping laps into one continuous membrane. Seam quality is where single-ply roofs succeed or fail, so it gets probed and checked as the work goes.
- Deck & insulationInsulation is fastened or adhered over the deck to meet energy requirements and set the drainage plane.
- Cover boardA hard layer protects insulation from foot traffic and hail and gives the membrane a uniform base.
- Membrane & weldsSheets are mechanically attached or fully adhered, then lap seams are hot-air welded.
- Flashings & edgesCurbs, penetrations, walls and perimeter metal are detailed. This is where most leaks start.
Actual assemblies depend on deck type, code and manufacturer requirements.
