Owensboro TPO roof coating restores aged single-ply roofs: seams closed, surface cleaned, a primer made for TPO applied, then a full coating.

Aging TPO
Owensboro TPO roof coating depends on bond. TPO has a slick, chemical-resistant surface, so a coating applied straight onto it can peel. A thorough cleaning and a primer made for single-ply give the coating something to grip.
Before any primer, open seams are rewelded or covered with seam tape, and loose membrane is fastened down. The coating then covers seams and field alike, so the old weld lines sit under one continuous surface.

Is This Roof a Fit?
An aged TPO roof can be coated if the membrane is still attached and the insulation under it is dry.

Roof Conditions
TPO roofs around Owensboro show their age in these four ways.
Heat-welded seams can let go at corners and T-joints, especially where installers worked fast or the weld was cold.
What We Do
Reweld where the membrane allows, or cover the seam with tape.
Older TPO develops fine cracks as the top layer weathers, starting on the sunniest parts of the roof.
What We Do
Patch cracked areas and coat over the field after priming.
Membrane that lifts and billows in wind has lost fasteners or adhesive along a row.
What We Do
Refasten or readhere the membrane before any coating.
Service technicians, dropped tools, and debris leave small punctures near rooftop units.
What We Do
Patch punctures and add walk pads on the main service paths.
Coating Options
Coatings for TPO all start with the same primer step.
| Option | Where It Fits | Watch For |
|---|---|---|
| Silicone over TPO primer | TPO roofs with some ponding | Recoat with silicone later |
| Acrylic over TPO primer | TPO roofs that drain fast | Needs dry curing weather |
| Seam tape plus coating | TPO with scattered open seams | Tape must match the membrane |

Qualified Benefits
Coating gives an aged TPO roof these benefits once it passes inspection. Loose or saturated TPO needs repair or replacement first.
Coating over the existing TPO avoids tear-off and new insulation, so the job prices below a new single-ply roof.
Warehouses, plants, and offices under the roof keep working while each section is primed and coated.
Only damaged sections come off the roof, so far less old membrane goes to the landfill.
A coated TPO roof can be cleaned and recoated when the surface wears, if the membrane stays attached.
Process
TPO coating uses the four stages, with seam work and adhesion testing at the front.
We probe every seam, check attachment along fastener rows, take moisture readings, and run an adhesion test with the primer and coating we plan to use.
Open seams are rewelded where the membrane accepts heat, or covered with compatible tape. Loose membrane is refastened and punctures patched.
The membrane is scrubbed and rinsed to remove dirt and oxidation, dried, and primed with a single-ply primer.
Seams and details get a reinforcing coat, then the field is coated at the specified thickness and checked with readings.

Answers for owners of aging single-ply roofs.
TPO coating falls in our $2.50 to $4 per square foot ballpark range. Seam repair, refastening, and the primer add labor, so a TPO roof with many open seams lands higher in the range than one with tight seams.
A slick surface designed to resist chemicals is part of what TPO is, and that surface also resists coatings. A cleaning to remove oxidation and a primer made for single-ply give the coating a surface it can bond to.
Yes, an aged TPO roof can be coated if the membrane is still attached and the insulation is dry. Open seams are repaired and a single-ply primer is applied before the coating.
Silicone is the common choice on flat TPO roofs where water lingers, and acrylic works on TPO that drains quickly. Both need the single-ply primer underneath.
Many can. Clean, aged TPO often accepts a heat weld after the surface is prepared with a membrane cleaner. Where a test weld will not hold, the seam is covered with compatible seam tape before primer and coating go on.
Coat it when the membrane is attached, seams can be closed, and moisture readings show mostly dry insulation. Replace it when large areas of insulation are wet or the membrane is cracked across most of the roof.
