TPO Roofing Systems
Building Owners Please Note:
Many commercial buildings have aging modified bitumen or built-up roofing systems that remain structurally sound but have reached the end of their service life. In many cases, a complete tear-off is unnecessary.
Single-Ply TPO Roofing Systems
Thermoplastic Polyolefin (TPO) roofing systems are among the most popular commercial roofing solutions available today. TPO membranes provide excellent resistance to UV exposure, ponding water, weathering, and temperature fluctuations while delivering outstanding energy efficiency through their highly reflective surface.
The TPO membrane is mechanically fastened or fully adhered according to manufacturer specifications. All seams are heat welded to create a monolithic waterproof surface that provides exceptional long-term protection against leaks and weather intrusion.
Fully Adhered TPO Systems (Recovering Existing Flat Roof Systems)
A fully adhered TPO roofing system provides one of the most attractive and durable solutions for commercial flat roofing applications. Unlike mechanically attached systems, the membrane is bonded directly to the insulation substrate using manufacturer-approved adhesives, creating a smooth, uniform appearance with exceptional wind uplift performance.
Fully adhered systems are often specified for schools, medical facilities, office buildings, retail centers, churches, and high-profile commercial properties where appearance, energy efficiency, and long-term durability are priorities. Our fully adhered TPO roofing systems combine premium insulation, engineered drainage design, heat-welded waterproofing, and precision flashing details to create a roofing assembly built for long-term performance. Every project incorporates proper crickets, saddles, parapet flashings, and coping metal systems to maximize drainage, minimize maintenance, and provide years of reliable protection for your commercial property.
Mechanically Attached TPO Recover System
A mechanically attached TPO recover system allows building owners to install a new roofing assembly directly over the existing roof after repairs and preparation have been completed. This approach reduces disruption, minimizes landfill waste, and often provides a more economical solution than a full replacement.
Our mechanically attached TPO recover systems provide a cost-effective solution for restoring aging modified bitumen and built-up roofing systems without the expense of a complete tear-off. After necessary repairs are completed, a high-performance ISO insulation package is mechanically fastened to the existing roof assembly, creating an energy-efficient substrate for the new roofing system.
State-of-the-Art Seam Welding
Automated hot-air welding technology to create strong, consistent membrane seams. Robotic seam welders maintain precise temperature, pressure, and travel speed throughout the welding process, producing uniform welds across long roof runs.
This advanced equipment helps eliminate inconsistencies often associated with manual welding while improving installation efficiency and overall seam quality. Every seam is subsequently inspected and probed by trained technicians to verify proper fusion and long-term waterproof performance. Why It Matters: the seam is the backbone of a TPO roofing system. A properly welded seam transforms individual membrane sheets into a single monolithic waterproof surface. By combining automated welding technology with experienced craftsmanship and thorough quality control, we provide commercial roofing systems engineered for durability, reliability, and long-term performance.
Recovering Over Existing Built-Up (Tar & Gravel) Roofing Systems
Many commercial buildings still have older built-up roofing (BUR) systems consisting of multiple layers of asphalt, felts, and embedded gravel. While these roofs can often be restored rather than completely torn off, proper surface preparation is absolutely critical to the success of the new roofing system.
Our restoration process begins with the removal of loose gravel and surface contaminants using specialized vacuum equipment. The existing roof is then mechanically prepared using rotary wire-brush machinery to create a clean, stable substrate for the new roofing assembly.
A Smart Alternative to Tear-Off
TPO Retrofit Over Existing Metal Roof Systems
A TPO retrofit system installed over an existing R-panel or standing seam metal roof is one of the most effective ways to extend roof life, improve energy efficiency, and eliminate recurring leak issues without the expense of a complete tear-off.
Before installation begins, the existing metal roof is inspected for structural integrity, loose fasteners, damaged panels, and areas requiring repair. Any deficiencies are corrected before the retrofit assembly is installed. Metal roof panels contain ribs and valleys that create an uneven surface. Custom Flute-fill insulation is installed within these low areas on the R-Panels to create a more uniform substrate.
A high-density cover board is then machicanlly attached over the Flute-fill insulation. Special engineered fastener patterns designed to meet local wind uplift requirements will be applied.
Our TPO Roofing Process
We make TPO roofing straightforward, efficient, and built around long-term performance. Our process is designed to protect your property, control costs, and give you a clean, watertight roof system you can trust.
Inspection, Core Review & Roof Plan
We start with a detailed roof inspection to check membrane condition, moisture risk, drainage, flashing, and insulation performance. We also review attic or interior heat and ventilation issues when needed, then build a clear TPO plan with pricing, timeline, and retrofit recommendations.
System Design & Installation Prep
Before installation, we confirm measurements, material specs, attachment method, and edge detail requirements for your building. Our team coordinates scheduling, delivery, safety setup, and tear-off or overlay prep so the TPO system goes on smoothly with as little disruption as possible.
TPO Installation, Sealing & Final Walkthrough
We install the TPO membrane with attention to welded seams, penetrations, drainage points, and flashing details that prevent leaks over time. After completion, we perform a final quality check, clean the site, and walk you through the finished system so you know exactly what was done and what to expect next.
TPO Roofing Systems FAQs
Common questions we hear from property owners in Richardson and across the Dallas–Fort Worth area about TPO roof replacement, retrofits, repairs, and long-term performance.
- What is a TPO roofing system, and why do property owners choose it?
TPO is a single-ply commercial roofing membrane used on low-slope and flat roofs. Property owners choose it because it is durable, cost-effective, and built for long-term performance. It helps reduce heat buildup on the roof, resists many common weather issues, and can be a smart option for offices, retail buildings, warehouses, churches, and multifamily properties. At Pillar Roofing, we install and retrofit TPO systems with a focus on proper drainage, seam quality, and long-term leak protection.
- How do I know if my building is a good fit for a TPO roof?
TPO is often a great fit for commercial buildings with a flat or low-slope roof, especially when the current roof is aging, leaking, or costing too much in repairs. We start with a full roof inspection to check the existing membrane, decking, insulation, drainage, and problem areas around penetrations and flashing. Because we specialize in commercial roofing restoration and TPO retrofits, we can tell you whether repair, coating, or a full TPO system makes the most sense for your building and budget.
- Can you install TPO over my existing roof, or does everything have to be torn off?
In many cases, a TPO retrofit can be installed over an existing commercial roof, but it depends on the condition of the current system and local code requirements. If the roof is structurally sound and qualifies, a retrofit can save time and reduce disruption to your property. If there is trapped moisture, major damage, or substrate issues, a tear-off may be the better choice. We will inspect the roof and give you a clear recommendation based on what protects your building best, not on what sells the biggest job.
- How long does a TPO roof last?
A properly installed TPO roofing system can last for many years, especially when it is matched to the building correctly and maintained over time. Lifespan depends on installation quality, roof traffic, storm exposure, drainage, and how quickly small issues are addressed. We have been serving the DFW area since 2004, and we know the details that matter, from seam work to flashing to moisture protection. We also offer roof maintenance plans to help extend roof life and catch problems early.
- What problems can cause leaks in a TPO roof?
Most TPO leaks come from poor seam welding, failed flashing, punctures, ponding water, or issues around penetrations like HVAC units and vents. On retrofit jobs, hidden moisture or fastener problems under the surface can also lead to trouble if not handled correctly. Our team takes a careful inspection-first approach so we can find the real source of the problem. We also work on roof coatings and fastener encapsulation when appropriate to help stop leaks and prevent further damage.

Yes. We provide free estimates and consultations for TPO roofing systems at commercial properties in Richardson and throughout the Dallas–Fort Worth area.

"Pillar Roofing replaced my roof and gutters last month and they did an excellent job. Steve and George are awesome! They were very quick to respond and answer any questions that we had. I highly recommend Pillar if you need a new roof!!"
"Can’t recommend Pillar Roofing enough! Steve and Wayne came out within a day of my talking to them, took their pictures and came back with several bid offers, everything from a full rebuild to simply minimal patching. We went with the middle road of doing a liquid TPO, which they got done in record time, and hauled off all their materials. No leaks on that project since, and we had them back out for another roof that started leaking after that terrible 2022 north Texas rainstorm. Same story, record time for the bid, and they got it done with no hassle on our end. Highly recommended! John Lee Harrison- The Armstrong Foundation"

"EXTREMELY SATISFIED CUSTOMER! When I was first shopping for roofers for a major skylight leak I couldn’t even find an honest roofer. We have cameras all around our house. We had two roofers give us a quote to replace the entire roof that didn’t even get on top of our roof! BLAKE from Pillar Roofing came out and then met with me to go over his quote and suggested we get an insurance adjuster out because he saw some hail damage. Our roof was over 20 years old. So we did and the inspector agreed. Blake walked me through the entire process and answered all my questions. His crew showed up even earlier than Blake advised on both days. They cleaned up after demo and after install. They completed the job when Blake advised. The roof looks amazing and all my neighbors are asking for their number! Blake is extremely knowledgeable and took time to explain the process to me and everything he advised was true to what occurred. Blake is personable, patient, and very responsive. I felt completely at ease working with Blake on this major project! I am extremely pleased with Pillar Roofing!!!"

I'm happy. Thank you."

"I could not have asked for better service. I was hit by the two major hail storms in Wylie. After the first one, I contacted Blake Joyce to look at my roof.........wasn't sure if I needed to contact my insurance company. He came out right away and confirmed the call. Needless to say, the second one hit and I then had hundreds of holes in my roof..........water coming in everywhere. My adjuster was already scheduled to come out the day after. Once he gave the OK......Blake had his crew were out to cover the roof that night..........by Friday (which was before the next big rain that came) he had our beautiful new roof going and finished Saturday morning. Thank you Pillar/Blake Joyce for the awesome job done and being so kind and patient! Karen Clevenger"
"Pillar handled the storm repair on my house in Wylie, TX in 2017. They repaired my roof, repaired my gutters, replaced my siding, and recommended a great guy to help repair and update my AC unit. They handled all the arrangements with me remotely as I was living out of state at the time. Their customer service was a huge help to me. They were honest, responsive, and understanding. I highly recommend this family owned company. Thank you Pillar!"
"Pillar Roofing was really great. We had our roof ruined in the spring hail storm of 2017 and they were among many roofers we talked to. Pillar gave us a reasonable quote, they were on time and the work was really terrific. And they cleaned up after the job! I highly recommend them."
"Got hit pretty bad with the Murphy Hail Storm last Spring. Steve the owner was personally engaged as well as several of his staff. He took us through the entire process and explained what to expect and the timing from start to finish. He worked directly with our Insurance company and assured all our damage was repaired and even pointed out things to the adjuster that we had no clue were covered. Very satisfied with the results and the professionalism of the crew. While I hope we never have to go through that again, you can be sure we will be calling Pillar Roofing if we do."

"Great company, great customer service!"
"I recently (late 2014) had a fairly major interior and exterior paint job, and woodwork replacement, done to my house. Our house is completely painted brick and fascia, a rather large job. I couldn't be happier with the level of service I received from Pillar Construction. I am a very picky person and they more than satisfied me. I would be happy to answer any questions from a perspective customer, or anyone else, but can't say enough good things about the services performed. They exceeded my expectations!!"
