Drive the industrial corridors off Jupiter Road, Miller Road, or Shiloh Road in Garland, TX, and you are looking at square mile after square mile of low-slope commercial roof — most of it aging, a lot of it patched, and nearly all of it a candidate for TPO. TPO roofing Garland, TX has become the default answer for warehouses, retail strips, offices, and multifamily flats, but “default” does not mean “automatic.” Wortham Brothers Roofing has installed roofing systems across North Texas since 1986, and the honest answer is that TPO is the right call for most Garland commercial buildings — and the wrong one for a few. This guide gives you the real 2026 numbers, the comparison, and the decision framework a building owner actually needs.

Key Takeaways
- Installed TPO in Garland runs $6.50–$11.50 per sq ft in 2026 depending on membrane thickness, insulation, and tear-off scope.
- A properly installed 60-mil TPO system lasts 20–25 years under North Texas sun; white TPO reflects heat that dark roofs absorb, cutting summer cooling loads measurably.
- TPO beats EPDM on Texas heat reflectivity and beats modified bitumen on seam reliability; standing-seam metal beats TPO on lifespan but costs roughly double.
- Hail is TPO’s weak point below 60-mil — Garland’s storm history argues for thicker membrane and cover board, not the cheapest bid.
- The most common commercial roof failure WBR inspects in Garland is not the membrane — it’s the flashing details at pipe penetrations, HVAC curbs, and termination bars.
- Wortham Brothers backs commercial installs with a written 10-year workmanship warranty on top of manufacturer coverage.
What TPO Actually Is — And Why It Took Over Garland’s Skyline
No commercial roofing material has taken market share faster in North Texas than TPO, and the reasons are practical, not trendy.
TPO — thermoplastic polyolefin — is a single-ply membrane, usually white, mechanically fastened or fully adhered over insulation, with seams that are heat-welded rather than glued or torched. That distinction matters enormously in Garland’s weather cycle: roof surface temperatures pushing 160°F in July, then sudden 2-inch downpours — a cycle that destroys glued and torched seams over time. A properly heat-welded TPO seam is monolithic. Done right, it is stronger than the membrane surrounding it.
That seam reliability, combined with a reflective white surface in a climate where cooling is the dominant energy cost, is why TPO now covers most new low-slope construction from the Firewheel retail district down to the warehouse blocks along I-635 and IH-30. White TPO reflects solar radiation that black EPDM absorbs — and in Garland’s nine-month cooling season, that difference shows up on utility bills, not just on specification sheets.
What TPO Roofing Costs in Garland in 2026
The question every owner actually has. Real Garland-area ranges for 2026:
What TPO Roofing Costs in Garland in 2026
| System | Installed Cost / Sq Ft | Expected Lifespan | Honest Garland Assessment |
|---|---|---|---|
| 45-mil TPO, mechanically fastened | $6.50–$8.00 | 15–20 yrs | Entry-level spec; adequate for sheltered applications with modest hail exposure |
| 60-mil TPO, mechanically fastened | $7.50–$9.50 | 20–25 yrs | The Garland standard — thick enough for most hail events, cost-effective on large footprints |
| 60-mil TPO, fully adhered + cover board | $9.00–$11.50 | 20–25 yrs | Best hail resistance in the class; gypsum cover board absorbs impact before the membrane |
| 80-mil TPO, fully adhered | $10.50–$13.00 | 25–30 yrs | Premium spec for high-value or hail-exposed buildings; rarely cost-justified on standard warehouses |
| Modified bitumen (2-ply) | $6.00–$9.00 | 15–20 yrs | Better puncture resistance than thin TPO; seams and surface age faster in UV |
| EPDM (black rubber) | $6.00–$8.50 | 20–25 yrs | Good lifespan; absorbs heat rather than reflecting it — the wrong call in Garland’s cooling climate |
| Standing-seam metal | $12.00–$18.00 | 40+ yrs | Wins on lifespan; costs roughly double 60-mil TPO — right for 30+ year horizons and load-bearing structures |
On a typical 20,000 sq ft Garland warehouse, that is roughly $150,000–$230,000 for a quality 60-mil system — and a $30,000–$50,000 spread between the cheapest possible install and one built to survive Garland hail. Those are not equivalent products.
Tear-off of an existing roof adds $1.00–$2.50/sq ft. A recover — installing over one existing layer where code and decking allow — saves most of that, and WBR tells building owners honestly when a recover is legitimate versus when it is burying wet insulation under a new membrane. The only way to know which situation you are in is a core sample during the inspection.
If you have three bids on a Garland commercial roof and the numbers are far apart, the difference is almost never in the membrane — it is in the insulation, the cover board, and the flashing scope.

TPO vs. EPDM vs. Modified Bitumen: The Honest Comparison
Which system should a Garland building owner actually choose? The right answer depends on three variables: heat, hail, and horizon.
TPO vs. EPDM vs. Modified Bitumen: The Honest Comparison
| Factor | TPO | EPDM | Modified Bitumen |
|---|---|---|---|
| Heat reflectivity | Excellent — white surface reflects most solar radiation | Poor — black absorbs heat; wrong for Garland’s cooling-dominant climate | Good — surface reflects, but seams and texture trap heat faster |
| Seam reliability | Excellent — heat-welded seams are stronger than the membrane | Adequate — factory-seamed rolls hold; field seams vary by crew | Variable — torch-applied seams degrade faster in sustained UV |
| Hail resistance (standard spec) | Moderate — 45-mil is vulnerable; 60-mil + cover board is strong | Good — rubber absorbs impact better than thin TPO | Good — asphalt layers resist puncture; surface granules degrade |
| Lifespan in DFW | 20–25 yrs (60-mil) / 25–30 yrs (80-mil) | 20–25 yrs | 15–20 yrs |
| Installed cost (Garland 2026) | $6.50–$11.50 / sq ft | $6.00–$8.50 / sq ft | $6.00–$9.00 / sq ft |
| Best for Garland | Most new commercial construction, warehouses, retail | Budget-limited projects; northern climates better fit | Recover-over applications; older buildings with limited slope |
Heat is where TPO wins in this market decisively. Garland’s cooling season dominates energy costs in a way that simply does not apply to climates where EPDM originated. The black-rubber argument made in Ohio makes no sense on a warehouse off Miller Road in August.
Hail is where specification thickness matters most. Garland’s storm record — 13 decay-weighted events in recent NWS tracking — keeps producing quarter-to-golf-ball hail. Thin 45-mil TPO over bare polyiso insulation punctures; 60-mil membrane over a gypsum cover board holds up dramatically better. That specification difference is exactly what separates a durable roof from a cheap one.
Horizon determines when metal makes sense. If a building owner plans to hold the asset 30-plus years and the structure supports the load, standing-seam metal wins on pure lifespan at roughly double the installed cost of TPO. Most Garland building owners with a 10-to-20 year horizon land on 60-mil TPO as the value play.
WBR Field Insight
The Most Common Failure Is Not the Membrane
The most common commercial roof failure we inspect in Garland is not the membrane — it is the details. Pipe penetrations, HVAC curbs, and termination bars flashed by the lowest bidder fail years before the field of the roof does. A 60-mil TPO field can look sound and be completely dry while every penetration collar on the roof is beginning to separate.
When you compare commercial roofing bids, compare the flashing scope line by line. How many pipe boots? New curb flashings or reused? Termination bar at every perimeter edge or caulk over existing? That is where the cheap bid got cheap.
What a Garland TPO Installation Actually Looks Like
Process removes uncertainty. Here is the sequence on a commercial TPO replacement:
What a Garland TPO Installation Actually Looks Like
| 1 | Free documented inspection with core samples Confirms what is under the existing roof — wet insulation must come out; a recover over wet insulation traps moisture and fails early. |
| 2 | Written scope and fixed proposal Membrane thickness, insulation R-value, cover board, flashing details all specified — so you can compare bids line by line. |
| 3 | Schedule around your operations Most 15,000–25,000 sq ft Garland buildings take 4–8 working days, sequenced in sections so the building stays watertight every night. |
| 4 | Installation by trained crews Seam welds and flashing details are the work — this is where the cheap bid shows up, two to five years later. |
| 5 | Final walkthrough, photos, and warranty registration Manufacturer warranty registered, written 10-year workmanship warranty issued — both in your file before the crew leaves the parking lot. |
On sequencing: Garland’s commercial tenants cannot shut down for a week while their roof is replaced. WBR sections the work so that every area opened for tear-off is dried in the same day, and the building is watertight every night. That is an installation-quality question as much as a scheduling one — it requires enough crew and enough organization to keep the sequence moving without exposed deck sitting overnight.
Maintenance: The Part That Decides Whether You Get 15 Years or 25
A common owner mistake is treating a new TPO roof as finished business. The membrane specification determines the ceiling; maintenance determines whether you reach it.
TPO Roof Maintenance
| Maintenance Item | Frequency | Why It Matters |
|---|---|---|
| Twice-yearly inspection | Spring and post-storm season | Catches flashing separations, seam lifts, and curb failures before they are interior leaks |
| Drain clearing | Before each storm season and after heavy leaf fall | Ponding water is the quiet killer on flat Garland warehouse roofs — standing water degrades TPO faster than UV |
| Flashing touch-ups | As identified during inspection | Pipe penetrations, HVAC curbs, and termination bars are where cheap installs fail first |
| Photo log | At each inspection visit | Documents roof condition over time, supports warranty claims, and provides dated evidence for future insurance disputes |
Budget $0.10–$0.25 per square foot annually for a maintenance program. On a 20,000 sq ft building, that is $2,000–$5,000 per year to protect a $150,000–$230,000 asset — and to keep manufacturer warranty coverage enforceable. Most manufacturer warranties include inspection and drain-clearing requirements; a roof that is never maintained is a warranty that may not pay when it matters.
If you have a Garland commercial property and you are not sure what system is under it or how much life is left, a core-sample inspection answers both before you commit to a budget or a bid.
Why Garland Building Owners Choose Wortham Brothers Roofing
Garland’s commercial corridors were built decades ago, and a lot of those roofs are on borrowed time. The contractor who installs the next one matters: when a seam fails in year eight on a warehouse full of product, the warranty is only as good as the company that signed it.

How much does TPO roofing cost in Garland, TX?
Installed TPO in Garland runs $6.50–$11.50 per square foot in 2026, depending on membrane thickness, insulation, cover board, and tear-off scope. A typical 20,000 sq ft building lands between $150,000 and $230,000 for a quality 60-mil system.
How long does a TPO roof last in Texas?
A properly installed 60-mil TPO roof lasts 20–25 years under North Texas heat, and 80-mil systems can reach 30. Maintenance — clear drains and twice-yearly inspections — determines which end of that range you get.
Is TPO better than EPDM in North Texas?
For most Garland buildings, yes. White TPO reflects heat that black EPDM absorbs — a meaningful difference in a climate where cooling dominates energy costs — and TPO’s heat-welded seams outlast glued EPDM seams in the North Texas heat cycle.
Does hail ruin TPO roofs?
Thin 45-mil TPO over bare insulation is vulnerable to large hail, but 60-mil or thicker membrane over a gypsum cover board performs dramatically better. Given Garland’s storm history — 13 decay-weighted hail events in recent NWS tracking — specifying the thicker assembly rather than the cheapest bid is the right call.
Can you install TPO over an existing roof?
Often, yes. Texas code generally allows a recover over one existing roof layer if the insulation is dry and the deck is sound. Core sampling during a free inspection confirms whether a recover is legitimate for your building or whether it would trap wet insulation under the new membrane.
How long does a commercial TPO installation take?
Most 15,000–25,000 sq ft Garland buildings take 4–8 working days, sequenced in sections so the building stays watertight every night and your operations keep running.
Does a white TPO roof really lower cooling costs?
Yes. Reflective white membranes measurably reduce rooftop temperatures versus dark roofs, cutting rooftop-unit runtime through Garland’s long cooling season. The savings are largest on older buildings with modest insulation — which describes most of Garland’s commercial stock along the industrial corridors.
What warranty comes with a TPO roof from Wortham Brothers?
Manufacturer membrane warranties of 20–30 years depending on the system specified, plus Wortham Brothers’ written 10-year workmanship warranty covering the installation itself — the seams, flashings, and penetrations that are the first things to fail on a cheap install.
