TPO Problems

TPO Roofing Problems We Fix in Louisville

TPO is a durable membrane, but these four problems show up on Louisville TPO roofs as they age.

Seams

Poorly Welded Laps

A seam welded too cold peels open over time. Probing finds the weak lengths, which are cleaned and rewelded. Test welds at the start of each day help prevent cold welds on new TPO.

Usually Means: Welder heat or speed was off during install

  • Punctures From Service Traffic

    Tools and boots near rooftop units puncture TPO.

  • Shrinking at Walls and Curbs

    Aging TPO can pull at corners and curbs, stressing the flashing.

  • Ponding Near Drains

    Water that sits on TPO collects dirt and wears the surface.

  • Flashing Split at Curbs

    Older TPO flashing around unit curbs cracks at inside corners.

TPO Options

TPO Roofing Options for Louisville

TPO can go on several ways. The attachment method depends on the deck, the wind exposure, and the insulation plan.

MethodHow It Goes DownCommon Use
Mechanically AttachedPlates and screws through the seams into the deckLarge steel-deck warehouses
Fully AdheredGlued to cover board with adhesiveOffices and roofs with odd shapes
Induction WeldedMembrane welded to plates under itHigher wind areas and fewer seam fasteners
TPO RecoverOver one dry existing layer with cover boardRoofs that qualify for a recover
TPO RepairCleaned, primed, and welded patchesPunctures and split seams on existing TPO

Why TPO

Benefits of TPO Roofing for Your Building

TPO offers several practical advantages on Louisville commercial buildings with large low-slope roofs.

On The Roof

  • Reflective White Surface

    The white membrane reflects summer sun, which helps buildings with heavy cooling loads keep roof temperatures down.

  • Welded Seams

    Hot-air welding fuses the laps into one piece, which holds up better than glued seams on a big roof.

Inside The Building

  • Cooler Space Under the Roof

    A white TPO surface reflects summer sun off the roof field, which helps warehouses and retail spaces below with heavy cooling loads.

  • Stock Kept Dry

    Welded seams and flashed curbs keep water away from racking, inventory, and finished goods under big warehouse roofs.

For Planning And Budget

  • Simple to Repair

    Clean, primed TPO accepts welded patches, so punctures and seam failures can be fixed for years.

  • Repairs Priced Low Later

    Clean TPO takes a welded patch for years, so future punctures near rooftop units stay small, inexpensive repairs.

TPO Process

How a TPO Roofing Job Runs, Step by Step

TPO goes down in a set order so every seam can be welded and probed before the crew leaves the roof.

  1. Inspect Your Roof

    We check the deck, the existing layers, and the drains, and take cores to find wet boards before planning the TPO.

  2. Prep and Insulate

    Old roofing or wet boards come off, then polyiso and cover board go down with tapered sections toward the drains.

  3. Roll and Weld

    Wide TPO rolls are laid out and attached, and an automatic welder runs every seam at a set heat and speed.

  4. Probe and Flash

    Each seam is probed, curbs and walls are flashed, and edge metal is set before the final roof walk.

About TPO

Why TPO Shows Up on So Many Louisville Roofs

TPO is a single-ply thermoplastic membrane, usually white, that comes in wide rolls and joins at the laps with hot air instead of glue. On the large, open roofs of Louisville warehouses, distribution centers, and retail centers, that combination means fewer seams and a reflective surface over spaces that get hot in summer.

A TPO roof is only as good as what sits under it, so insulation, cover board, and drain heights get as much planning as the membrane itself.

  • Seams fused with hot air
  • White surface reflects summer sun
  • Polyiso and cover board underneath
  • Drain heights set to the new roof

Louisville TPO Roofing Questions

TPO compared with EPDM, and what to know before putting TPO on a warehouse.

Roof Condition

What is the difference between TPO and EPDM roofing?

TPO is white thermoplastic with heat-welded seams and a reflective surface. EPDM is black synthetic rubber with taped or adhered seams that stays flexible in cold weather. On Louisville flat roofs the better choice comes down to the building's cooling load, movement, deck, and any existing membrane to match.

Is TPO a good choice for Louisville warehouses?

Yes, for most of them. Wide TPO rolls and welded seams keep seam counts low on big warehouse and distribution roofs, and the white surface reflects summer heat. Before installing it, we check the deck, the insulation, and the drains, since those decide how long the new membrane lasts.

Membranes and Systems

Can TPO go over my existing roof?

If there is only one existing layer and the insulation is dry, a TPO recover over a cover board is often possible. Two existing layers, or wet boards found in core samples, mean a tear-off first.

How are TPO seams checked after welding?

Every TPO seam is probed along its full length after welding, and test welds are made at the start of each day to set the welder's heat and speed. Any cold or narrow weld found by the probe gets rewelded before the crew moves on.

Planning the Work

How thick should a new TPO membrane be?

Thicker TPO sheets hold up better to foot traffic and hail on busy warehouse roofs. We match the thickness to the traffic, rooftop equipment, and wind exposure of your building and list it in the written scope.

Is white TPO worth it in Louisville winters?

Yes for most commercial buildings. The reflective surface helps most during Louisville's hot, humid summers, and with good insulation under the membrane the winter heat loss stays low. Snow and ice sit on TPO the same way they sit on any low-slope roof, so drains need to stay clear.
