Our TPO work is part of the broader commercial roofing in Irving we do for offices, warehouses, retail and apartments. This page covers what TPO is, how we install it, where it fits better or worse than other single-ply options, and when an aging TPO roof needs repair rather than replacement.
A white roof membrane for Texas sun
TPO (thermoplastic polyolefin) is a single-ply roofing sheet, reinforced with a fabric scrim and supplied in wide rolls. Its seams are melted together with hot air instead of glued, so a good weld becomes one continuous piece of membrane. The white surface reflects much of the sun's heat, which matters in a city where July highs sit around 95°F and the record is 112°F.
Irving cool-roof, permit and registration rules for TPO
Reflectivity is also a code issue here. Irving's local energy amendments (Chapter 8B) require a solar reflectance index (SRI) of at least 78 for low-slope roofs. White TPO is a common way to meet it; darker membranes often are not. A TPO reroof needs a City of Irving permit, and the city requires contractors to hold an annual registration; one published fee schedule lists $150 for a multifamily or commercial reroof permit, so confirm the current figure by calling Irving Inspections at (972) 721-2371. The state adds no layer of its own: Texas does not license roofing contractors, according to TDLR, which is why the city registration matters.
TPO roof installation in Dallas–Fort Worth: our process
- Inspect, core and prepare. We walk the existing roof, take core samples and decide on a recover or tear-off; then damaged deck is replaced, or on a recover, wet areas are cut out and filled.
- Insulate and slope. Polyiso insulation and tapered crickets go down to meet the energy code and move water to drains.
- Attach the membrane. Depending on deck type and wind exposure, TPO is mechanically fastened at the seams, fully adhered, or held with induction-welded plates.
- Weld and probe. Seams are hot-air welded, cooled, then probed along their full length.
- Flash details. Curbs, walls, pipes, drains and edges get TPO flashing, prefabricated corners and termination bars.
- Edge metal, walkways and final walk. New coping, drip edge or gravel stop goes on, walkway pads mark service routes to rooftop units, and we review the roof with you, clean up and hand over photos.
TPO vs PVC and other single-ply roofing in DFW
| System | Seams | Where it fits | Watch-outs |
|---|---|---|---|
| TPO | Hot-air welded | Offices, warehouses, retail; reflective white | Grease from kitchen exhaust can degrade it |
| PVC | Hot-air welded | Restaurants and roofs exposed to oils or chemicals | Usually costs more than TPO |
| EPDM | Taped or glued | Older buildings with existing rubber roofs | Black versions do not meet a high SRI |
| Modified bitumen | Torch, cold or self-adhered | Roofs with heavy foot traffic | Darker surfaces may need a reflective cap or coating |

What TPO roofing in Irving, TX includes with us
A TPO roof is only as good as the parts nobody sees once it is finished: the insulation under it, the welds between sheets, and the flashing at every curb and wall. So our scope covers the whole assembly, from the deck up. It also spells out how the membrane is attached, because fastener spacing at the corners and perimeter, where wind uplift is strongest, is not the same as in the middle of the roof. If your building already has a sound single layer, the scope explains whether a recover with a new cover board makes more sense than a full tear-off, and why. Each line below appears on the written estimate:
- core sample results and a written recover-or-tear-off recommendation
- insulation to the thickness the code requires, plus tapered slope where water ponds
- TPO membrane in the agreed thickness, with welded and probed seams across the field
- flashing at every curb, wall, pipe and drain, with new edge metal and walkway pads to rooftop equipment
- a permit plan stating which party applies for the Irving reroof permit
- photos of hidden details before they are covered, and a final walk
Does an aging TPO roof need repair or replacement?
Owners usually notice the warning signs from the roof hatch: seams lifting at their edges, a chalky white residue that rubs off on a glove, small cracks around the base of curbs, hail dents or punctures near the drains, and water still standing two days after a May storm. Heat drives most of it. A Western States Roofing Contractors Association field study reported surface cracking near field seams on 60-mil TPO in San Antonio after about seven years, and Irving's July sun is close kin to San Antonio's. Restaurant exhaust fans add a second cause, because grease softens TPO around the fan curb.
TPO roof repair works well when the membrane still welds: we clean the area, prepare the surface and weld new membrane over punctures, opened seams or torn flashing. As TPO ages, its surface can chalk and the top layer can wear thin, until new material will not bond. We test-weld before quoting a repair. If the membrane is past that point, or wet insulation has spread under it, a recover or commercial roof replacement is the realistic next step. For sound but weathered membrane, roof coatings can be an option once a moisture check confirms dry insulation.
What affects the price of a TPO roof?
We give free estimates rather than posted prices. The total depends on roof size and shape, tear-off versus recover, how much wet insulation must be removed, insulation thickness, tapered slope, membrane thickness, attachment method, the number of curbs and penetrations, edge metal, crane or lift access, and phasing for occupied space.
A few of those swing the number more than owners expect. Wet insulation is only fully counted once cores and a moisture check are done, so our estimate carries a unit price for replacing it. Thicker membrane (60 or 80 mil instead of 45) adds material cost but buys more protection against heat aging and hail. Fully adhered systems cost more than mechanically fastened ones but avoid fastener rows and suit some decks better. A roof crowded with exhaust fans, skylights and pipe stands takes far more flashing labor per square than an open warehouse roof. And because May is Irving's wettest month, a spring schedule may carry rain days. Our flat roof repair service is a lower-cost path if only a few areas have failed.
