Covers Air-Conditioned Offices or Retail

Fit Check
Is Your Roof a Fit for TPO?
A Covington TPO roofing contractor looks at what sits under the roof and what comes out of its vents before recommending the sheet.
If Your Roof
Sits on a Hilltop With Lots of Corners
Fully adhered TPO gives wind nothing to grab along plate rows, which suits exposed sites.
Start WithAdhered TPO
If Your Roof
Has Many Parapets and Offsets
Flexible rubber forms around odd corners more easily than a stiffer thermoplastic sheet in cold weather.
Start WithEPDM Roofing
If Your Roof
Takes Grease From Kitchen Exhaust
TPO resistance to oils varies by maker, so fan areas on restaurant and plant roofs get PVC or a grease-rated sheet.

What We Look For
Roof Conditions a Covington TPO Roofing Contractor Finds
These are the TPO details that decide whether a roof gets a repair, a recover, or new membrane.
Welds
Cold Spots in Seams
A seam probe catches gaps where the welder ran too fast or too cool, and those laps let water under the sheet.
T-Joints
Unpatched Three-Way Laps
Where three sheets meet, a small step in the lap needs a welded patch to close it.
Curbs
Loose Unit Flashing
Membrane run up the curb sides has to tuck under the unit’s counterflashing, or water gets behind it.
Traffic
Worn Service Paths
Foot traffic from hatch to rooftop units scuffs thin sheets unless walkway pads are welded down.
Edges
Loose Edge Metal
Low-slope edge metal has to be a tested design, and loose gravel stop lets wind peel the sheet back from the perimeter.
Drains
Unclamped Drain Rings
Sheet edges that slip out of a drain’s clamping ring lets water run under the sheet right at the lowest point of the roof.
System Choices
Commercial TPO Roofing Options for Covington
Three ways to hold a TPO roof down, matched to the deck, wind, and weight the structure can carry.
Mechanically Attached TPO
Screws and plates in the laps hold the sheet to steel or wood decks at a lower material cost; corners get tighter rows.
Fully Adhered TPO
Bonding adhesive across the whole sheet suits odd shapes, high wind, and quiet interiors, within the adhesive’s temperature limits.
Ballasted TPO
Stone or pavers hold the sheet on strong decks with parapets all around, though leak tracing means moving stone.
What It Does
Benefits of a New TPO Roof
TPO earns its place on Covington roofs where cooled space, welded seams, and steady foot traffic all matter.
Cooler Roof in Summer
A white sheet reflects sunlight, so the deck and the space below take on less heat than under a black membrane.
Welded, One-Piece Laps
Hot-air welds fuse overlapping sheets into one piece of plastic once cooled, with no tape or adhesive at the lap.
Thicker Sheet Where People Walk
Heavier TPO and welded pads around units and hatches take service traffic without wearing through.
Rated Products on Record
Reflectance values for specific TPO products are listed in the Cool Roof Rating Council directory.

Order of Work
How TPO Roofing Goes On in Covington
TPO installs run section by section, with every seam tested before the crew moves on.
Work Order5 Steps
- On The Roof
Inspect Your Roof
We check the deck, count curbs and drains, and scan for wet insulation that would have to come out before new TPO goes down.
- On The Roof
Set Insulation and Cover Board
Tapered insulation moves water to drains, and cover board shields it from hail dents and boots.
- On The Roof
Test Weld for the Day
Each morning a test weld is pulled apart to confirm heat and speed settings for that day’s temperature.
- On The Roof
Roll Out and Weld the Field
An automatic welder rides each lap, with hand welds at corners, curbs, and patches.
- Paperwork
Probe, Patch, and Photograph
A blunt probe checks every seam, T-joints get patches, and cut samples are taken where the maker asks.

TPO Questions From Covington Owners
What is a TPO roof, and where does it fit in Covington, KY?
White welded membrane
TPO is a thermoplastic polyolefin membrane rolled out in white sheets, with laps fused by hot air. Covington owners put it on warehouses, retail centers, offices, schools, and plants with low-slope roofs, and thicker sheets go where foot traffic around rooftop units is heavy.
TPO vs EPDM vs PVC: which commercial roof membrane fits?
Seams, color, grease
All three cover a low-slope roof well. TPO and PVC are welded and usually white; EPDM is taped rubber and usually black, staying flexible in cold weather. Over cooled offices or warehouses TPO cuts heat gain, while grease from a restaurant fan points to PVC near the exhaust.
How does TPO seam welding and probe testing work?
Test weld, then probe
An automatic hot-air welder rides each lap after a daily test weld is peeled apart to confirm settings. Afterward a blunt probe runs along every seam to find gaps, crews look for a small bead of melted material at the lap edge, and T-joints get a welded patch.
Mechanically attached vs fully adhered TPO: which is better?
Deck and wind decide
The deck type, wind exposure, and the weight the structure can carry decide it. Mechanically attached sheets use screws and plates in the laps on steel or wood decks; fully adhered sheets bond across the whole surface and resist flutter on hilltop sites and roofs with many corners.
What does TPO flashing around rooftop units and drains involve?
Hand work at details
Curbs get membrane run up their sides and tucked under the unit’s counterflashing, pipes get pre-molded boots with clamps, and drains get a sump plus a clamping ring that grips the sheet. Walkway pads welded from the hatch to each unit protect the membrane from service traffic.
Can new TPO go over an existing roof in Covington?
If it is dry and single
Yes, when only one roof is on the building and the insulation under it is dry. The old membrane gets a recovery board, then new TPO is welded over it. Wet areas found by scan are cut out first, and drains and curbs are raised to the new surface.
Does a white TPO roof need special cleaning?
Rinse, no scrubbing
A low-pressure rinse once a year clears dirt that dulls the white surface, and debris around drains comes off by hand. Pressure washers and harsh cleaners scar the sheet, so maintenance crews stick to the maker’s list of approved products.
