Reliable TPO Retrofit Systems
Lower energy costs and extend roof life with a durable retrofit installed by our RCAT-licensed commercial roofing team.
Service Details
At Pillar Roofing, we install TPO retrofit systems for commercial buildings that need a cost-effective way to improve roof performance without a full tear-off. A TPO retrofit system adds a new single-ply roofing membrane over an existing roof assembly when the structure and current roof are good candidates. This approach can lower disruption to your business, reduce landfill waste, and give you a durable, energy-efficient roofing solution.
TPO stands for thermoplastic polyolefin. It is a strong white roofing membrane known for heat-reflective performance, welded seams, and solid resistance to UV rays, ponding concerns, and normal weather exposure. For many flat roofs and low-slope roofs in North Texas, TPO is a smart option because it helps control rooftop temperatures and can support lower cooling costs during our long hot seasons.
What a TPO Retrofit System Includes
Every building is different, so we tailor the retrofit system to the roof condition, deck type, drainage layout, and budget goals. In most cases, a TPO retrofit system may include:
- Full roof evaluation and core review when needed
- Moisture assessment to check for trapped water in the existing system
- Replacement of wet or damaged sections before installation
- Cover board or insulation board to create a smooth, stable surface
- Tapered insulation options to improve drainage where possible
- Mechanically attached or fully adhered TPO membrane
- Heat-welded seams for a watertight bond
- New flashing at curbs, walls, pipes, drains, skylights, and roof edges
- Edge metal and termination details designed for wind resistance and long-term performance
When a Retrofit Makes Sense
A retrofit is often a good fit when your current commercial roof has aged but the overall assembly does not require complete removal. If the roof deck is sound and moisture intrusion is limited, a retrofit can be a practical way to extend service life and improve energy performance. We commonly recommend this service for property owners and facility managers who want to avoid the higher cost, downtime, and mess that can come with a full replacement.
That said, not every roof qualifies. If we find widespread moisture, severe deck damage, major structural issues, or conditions that would keep the new system from performing the right way, we will tell you plainly. Our job is to recommend the solution that protects your building best, not force a system where it does not belong.
Our Process
We start with a free estimate and consultation. We inspect the existing roof, look at drainage patterns, penetrations, flashing details, and signs of leaks or membrane failure. We also review the type of current roofing system, insulation condition, and any code-related requirements that may affect the retrofit design.
Once we confirm the roof is a good candidate, we build a clear scope of work. We explain material options, attachment methods, insulation upgrades, and expected project timeline. Before installation, we address damaged areas and prepare the surface so the new assembly has a clean, solid foundation.
During installation, our crew pays close attention to seam welding, flashing transitions, roof penetrations, perimeter details, and drainage points. These areas matter most on any commercial roofing system. When the job is complete, we perform a final review to make sure the system is installed with precision and care.
Benefits of TPO Retrofit Systems
- Lower project disruption: In many cases, retrofitting allows your building to stay more operational during the roofing project.
- Reduced tear-off costs: Keeping suitable existing materials in place can help lower labor and disposal expenses.
- Energy efficiency: White reflective TPO can help reduce heat gain and improve indoor comfort.
- Strong seam performance: Heat-welded seams create a durable bond that is a big advantage over many older roofing systems.
- Clean, updated roof surface: A retrofit can improve appearance while boosting weather protection.
- Potential life extension: When installed over a qualified roof, a retrofit system can provide dependable long-term service.
Common Applications
We install TPO retrofit systems on a wide range of commercial properties, including office buildings, retail centers, warehouses, light industrial facilities, churches, and multi-tenant properties. These systems work well on many flat and low-slope roof designs where energy efficiency, leak protection, and budget control are important.
Important Performance Details
The success of a retrofit depends on more than the membrane itself. Proper attachment, insulation setup, drainage planning, edge securement, and flashing workmanship all play a major role. We pay close attention to wind uplift needs, rooftop unit curbs, pipe boots, parapet walls, and transition areas. Those details are often where roof failures start if the work is rushed or done poorly.
We also help clients think through long-term roof care. Even a high-quality TPO roof needs routine inspections and maintenance to protect seams, drains, and penetrations. Our roof maintenance plans are designed to help commercial owners catch small issues before they turn into bigger repair costs.

TPO Retrofit Systems FAQs
Common questions we hear from commercial property owners about TPO retrofit roofing in Richardson and across North Texas.
- What is a TPO retrofit system?
A TPO retrofit system is a way to install a new single-ply TPO roofing membrane over an existing commercial roof when the building is a good fit for it. Instead of a full tear-off in every case, we add a new roofing system designed to improve waterproofing, protect the building, and extend roof performance. At Pillar Roofing, we inspect the current roof first to make sure a retrofit is the right choice.
- How do I know if my commercial roof is a good candidate for a TPO retrofit?
It depends on the condition of your current roof, the type of roof deck, moisture levels, and local code requirements. If the existing system has widespread structural issues or trapped moisture, a retrofit may not be the best option. That is why we start with a full roof inspection and honest recommendations. We will let you know whether a TPO retrofit, roof repair, or full replacement makes the most sense for your property.
- Is a TPO retrofit less expensive than a full roof replacement?
In many cases, yes. A retrofit can reduce labor, material removal, and disruption costs compared with a complete tear-off. That said, the real value comes from choosing the right solution for your roof, not just the lowest upfront price. We provide free estimates and consultations, so you can clearly compare your options and make a confident decision.
- How long does a TPO retrofit system last?
A properly installed TPO commercial roofing system can last for many years, especially when it is supported by regular inspections and maintenance. The lifespan depends on the roof design, drainage, weather exposure, and installation quality. Our team at Pillar Roofing focuses on doing the job right the first time, and we also offer roof maintenance plans to help protect your investment.
- Will a TPO retrofit interrupt my business operations?
We work hard to keep disruptions to a minimum. One reason many owners choose a retrofit roofing system is because it can often be completed with less mess and downtime than a full replacement. Before we begin, we will walk you through the project timeline, jobsite plan, and what to expect each day so your team can stay informed.
- Why should I choose Pillar Roofing for a TPO retrofit system?

"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"

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!!!"

This is an outstanding roofing company."

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!!"
